Answer:

Energy transformation

Explanation:

Energy transformation is when energy changes from one form to another.

Answer:

Explanation:

Consider the initial position of the frog (20 m above ground) as the reference position. All measurements are positive measured upward.

Therefore,

u = 10 m/s, initial upward velocity.

H = - 20 m, position of the ground.

g = 9.8 m/s², acceleration due to gravity.

Part (a)

When the frog reaches a maximum height of h from the reference position, its velocity is zero. Therefore

u² - 2gh = 0

h = u²/(2g) = 10²/(2*9.8) = 5.102 m

At maximum height, the frog will be 20 + 5.102 = 25.102 m above ground.

Answer: 25.1 m above ground

Part (b)

Let v = the velocity when the frog hits the ground. Then

v² = u² - 2gH

v² = 10² - 2*9.8*(-20) = 492

v = 22.18 m/s

Answer: The frog hits the ground with a velocity of 22.2 m/s

Answer:

30 m/s East

Explanation:

Velocity must have a speed unit (m/s) and a direction.  The only one that satisfies the conditions is 30 m/s East.

Answer:

(1).The acceleration is -24 m/s²

The total distance is 912 m.

(2). The distance traveled before it stop is 78 m.

Explanation:

Given that,

Velocity = (12-3t^2) m/s

When t = 1 s, the particle is located 10 m to the left of the origin.

We need to calculate the acceleration at t = 4 sec

Using formula of acceleration

[tex]a=\dfrac{dv}{dt}[/tex]

Put the value of v

[tex]a=\dfrac{d}{dt}(12-3t^2)[/tex]

[tex]a=-6t[/tex]

Put the value of t

[tex]a=-6\times4[/tex]

[tex]a=-24\ m/s^2[/tex]

The displacement from t = 0,t = 10 s, and the distance the particle travels during this time period.

We need to calculate the distance

Using formula of distance

[tex]ds=v\ dt[/tex]

[tex]\int_{-10}^{s}=\int_{1}^{t}{v}dt[/tex]

Put the value of v

[tex]\int_{-10}^{s}=\int_{1}^{t}{ (12-3t^2)}dt[/tex]

[tex]s+10=12t-t^3-11[/tex]

[tex]s=12t-t^3-21[/tex]

At t = 0,

[tex]s_{t=0}=-21[/tex]

At t = 10,

[tex]s_{t=10}=12\times10-10^3-21[/tex]

[tex]s_{t=10}=-901[/tex]

The displacement is

[tex]\Delta s=-901-(-21)[/tex]

[tex]\Delta s=-880\ m[/tex]

The distance at t= 2 sec

[tex]s_{t=2}=12\times2-2^3-21[/tex]

[tex]s_{t=2}=-5[/tex]

The total distance will be,

[tex]s_{T}=(21-5)+(901-5)[/tex]

[tex]s_{T}=912\ m[/tex]

(2). We need to calculate the distance at 2 sec

Using equation of motion

[tex]s=ut-\dfrac{1}{2}at^2[/tex]

Put the value into the formula

[tex]s=27\times 2+\dfrac{1}{2}\times6\times(2)^3[/tex]

[tex]s=78\ m[/tex]

Hence, (1).The acceleration is -24 m/s²

The total distance is 912 m.

(2). The distance traveled before it stop is 78 m.

Answer:A Ed 2020

Explanation:

In order to use the Pythagorean theorem to find the magnitude of a resultant vector, two initial vectors must form a 90 degree angle.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse.

Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

Hence,  two initial vectors must form a 90 degree angle.

Microwave is used to heat the food and uses a different form of electromagnetic radiation. The form of electromagnetic radiation used in microwaves are radio waves and infrared radiation.

The frequency of such electromagnetic waves is 2,450 megahertz (2.45 gigahertz) and the wavelength range is approximately of 30 cm (frequency = 1 GHz) to 1 mm (300 GHz).

Microwaves or electromagnetic radiation produced by a magnetron, an electron tube in the microwave. The cavity of the magnetron cavity magnetron produces electromagnetic waves defined wavelength. Electromagnetic radiation strikes within the metals in the microwave and is absorbed by food. Electromagnetic radiation allows the vibration of water molecules in the food and makes the food hot.

Answer:

Describe the device and its function.

A microwave has electro-magnetic waves. A microwave also heats up and cooks food.

What form of electro-magnetic radiation does it use?

They use infrared radiation.

Describe the frequency and wavelength range of this type of electro-magnetic wave.

Their frequencies are between 300 mhz and 300 ghz. A microwaves wavelength is around 30 centimeters.

Using the information above and details from your research, write a paragraph of five sentences or more explaining how the device uses the behavior and characteristics of the electro-magnetic wave to function. Remember the writing tips from the lesson, and use facts and details to explain your topic sentence.

The microwave heats up food and also cooks it. The form of the electro-magnetic radiation they use is “infrared”. A microwaves wavelength is also around 30 centimeters. Their frequencies run between 300 mhz and 300 ghz. Microwaves use the radiation as heat and power to warm their surroundings such as food placed in microwaves. A microwave can also be found right in your kitchen. Microwaves can heat up about almost everything, even metal. That is also the reason why you should not place any silverware in a microwave, because it can create an electrical current, causing it to explode out of control.

Answer:

a = 2.72 [m/s2]

Explanation:

To solve this problem we must use the following kinematics equation:

[tex]v_{f} =v_{o} + a*t[/tex]

where:

Vf = final velocity = 1200 [km/h]

Vo = initial velocity = 25 [km/h]

t = time = 2 [min] = 2/60 = 0.0333 [h]

1200 = 25 + (a*0.0333)

a = 35250.35 [km/h2]

if we convert these units to units of meters per second squared

[tex]35250.35[\frac{km}{h^{2} }]*(\frac{1}{3600^{2} })*[\frac{h^{2} }{s^{2} } ]*(\frac{1000}{1} )*[\frac{m}{km} ] = 2.72 [\frac{m}{s^{2} } ][/tex]

Answer:

x = v₀ cos θ   t ,   y = y₀ + v₀ sin θ t - ½ g t2

Explanation:

This is a projectile launch exercise, in this case we will write the equations for the x and y axes

Let's use trigonometry to find the components of the initial velocity

              sin θ = [tex]v_{oy}[/tex] / v₀

              cos θ = v₀ₓ / v₀

              v_{y} = v_{oy} sin θ

              v₀ₓ = vo cos θ

now let's write the equations of motion

X axis

         x = v₀ₓ t

         x = v₀ cos θ   t

        vₓ = v₀ cos θ

Y axis

        y = y₀ + [tex]v_{oy}[/tex] t - ½ g t2

        y = y₀ + v₀ sin θ t - ½ g t2

        v_{y} = v₀ - g t

       v_{y} = v₀  sin θ - gt

        [tex]v_{y}^{2}[/tex] = v_{oy}^2 sin² θ - 2 g y

As we can see the fundamental change is that between the horizontal launch and the inclined launch, the velocity has components

The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).

The short answer: The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now (and it could still be stretching).

The long answer: For most of human history, observers of the sky assumed it eternal and unchanging. Edwin Hubble dealt this story an experimental blow in the 1920s when his observations showed both that galaxies outside the Milky Way existed, and that their light appeared stretched — a sign that they were rushing away from Earth.

George Lemaître, a contemporary Belgian physicist, interpreted data from Hubble and others as evidence of an expanding universe, a possibility permitted by Einstein's recently published field equations of general relativity. Thinking backwards, Lemaître inferred that today's separating galaxies must have started out together in what he called the "primeval atom."

The first public use of the modern term for Lemaître's idea actually came from a critic — English astronomer Fred Hoyle. On March 28, 1949, Hoyle coined the phrase during a defense of his preferred theory of an eternal universe that created matter to cancel out the dilution of expansion. Hoyle said the notion that "all matter of the universe was created in one big bang at a particular time in the remote past," was irrational. In later interviews, Hoyle denied intentionally inventing a slanderous name, but the moniker stuck, much to the frustration of some.

"The Big Bang is a really bad term," said Paul Steinhardt, a cosmologist at Princeton. "The Big Stretch would capture the right idea." The mental image of an explosion causes all kinds of confusion, according to Steinhardt. It implies a central point, an expanding frontier, and a scene where light shrapnel flies faster than heavier chunks. But an expanding universe looks nothing like that, he said. There's no center, no edge, and galaxies large and small all slide apart in the same way (although more distant galaxies move away faster under the cosmologically recent influence of dark energy).

Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.

"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."

A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.

Misconseption: Beginning at the beginning, a common question asked by laymen and some physicists is what the universe expands into. The very terminology of the ``big bang'' suggests an explosion, which flings debris out into some void. Such a picture is strongly suggested by many semi-popular descriptions, which commonly include a description of the initial instant as one ``where all the matter in the universe is gathered at a single point'', or something to that effect. This phrase can probably be traced back to Lemaître's unfortunate term ``the primaeval atom''. Describing the origin of the expansion as an explosion is probably not a good idea in any case; it suggests some input of energy that moves matter from an initial state of rest. Classically, this is false: the expansion merely appears as an initial condition. This might reasonably seem to be evading the point, and it is one of the advantages of inflationary cosmology that it supplies an explicit mechanism for starting the expansion: the repulsive effect of vacuum energy. However, if the big bang is to be thought of explosively, then it is really many explosions that happen everywhere at once; it is not possible to be outside the explosion, since it fills all of space. Because the density rises without limit as t -> 0, the mass within any sphere today (even the size of our present horizon) was once packed into an arbitrarily small volume. Nevertheless, this does not justify the ``primaeval atom'' terminology unless the universe is closed. The mass of an open universe is infinite; however far back we run the clock, there is infinitely more mass outside a given volume than inside it.
