Hello!

[tex]\large\boxed{\text{C. 7,350,000 J}}[/tex]

Use the equation:

[tex]PE = mgh[/tex]

Where:

m = mass of the object (kg)

g = acceleration due to gravity (≈9.8 m/s)

h = height above ground (m)

Plug the given values into the equation:

PE = 7500 · 9.8 · 100

PE = 7,350,000 Joules.

Answer:

3.6 kg*m^2/s

Explanation:

The angular momentum equals mvr, where m is the mass, v is the velocity, and r is the radius or rotational arm. Inputting these values, we can find the angular momentum.

Angular momentum = (1.5 kg)(3.0 m/s)(0.8 m) = 3.6 kg*m^2/s

I hope this helps! :)

Answer:

3.6 kg is the answer

Explanation:

Explanation:

Answer:

See the explanation below

Explanation:

The watt (the power) is equal to the relationship between the work and the time in which that work is performed.

[tex]P = W/t[/tex]

where:

W = work [J] (units of Joules)

t = time [s].

Now 1000 [W] are equal to 1 [kW]

And 1000000 [W] are equal to 1 [MW]

The horsepower is the unit of power in the imperial system of units.

And 745.7 [W] are equal to 1 [Hp]

Answer:

[tex]a = 0\ m/s^2[/tex]

Explanation:

The acceleration of a body is defined as the change in velocity of an object, with respect to time. So, in order to produce and acceleration in any object, the velocity of that object must change. And, if the velocity of the object is not changing with respect to time, then the object is said to have a uniform motion. The acceleration of the object in such uniform motion is always zero. Because the change in velocity is zero.

[tex]acceleration = change in velocity/time\\acceleration = 0 / time\\acceleration = 0 m/s^2[/tex]

Since, the car in this case is moving with a constant speed. Therefore, its acceleration will also be zero.

a = 0 m/s²

Answer:

A difference between of echo and reverberation​  is described below in details.

Explanation:

Here's a piece of immediate information: An echo is an individual consideration of a soundwave off a horizon exterior. Reverberation is the consideration of sound waves generated by the superposition of the before-mentioned echoes. ... A reverberation can happen when a sound wave is displayed off a nearby covering.

Answer:

[tex]\boxed {\boxed {\sf 20 \ Hz}}[/tex]

Explanation:

The frequency of a wave can be found using the following formula.

[tex]f=\frac{v}{\lambda}[/tex]

where f is the frequency, v is the velocity/wave speed, and λ is the wavelength.

The wavelength is 10 meters and the velocity is 200 meters per second.

Therefore:

[tex]v= 200 \ m*s^{-1} \\\lambda = 10 \ m[/tex]

Substitute the values into the formula.

[tex]f=\frac{200 \ m*s^{-1}}{10 \ m}[/tex]

Divide and note that the meters (m) will cancel each other out.

[tex]f=\frac{200 \ s^{-1}}{10 \ }[/tex]

[tex]f=20 \ s^{-1}[/tex]

[tex]f= 20 \ Hz[/tex]

The frequency of the wave is 20 Hertz

Answer: 5N

Explanation:

Horizontal component is the force that is applied as a result of the diagonal application of force.

here in this case,

given diagonal force =10N.

angle= 30°

horizontal component is found using trigonometry..

so,

A vector of magnitude 10 N is provided.

It is at an angle of 30° to the + x axis.

To find:

The components along the x and y axis.

Calculation:

Along x axis:

F(x) = F cos(θ)

=> F(x) = 10 × cos(30)

=> F(x) = 10 (√3/2) = 5√3N

Along y axis:

F(y) = F sin(θ)

=> F(y) = 10 sin(30°)

=> F(y) = 10 × ½

=> F(y) = 5 N.

Additional information:

1. A vector is a quantity that can be defined with both magnitude and direction.

2. Since force is a vector, we are able to break it down into components along chosen axis.

Answer:

9.81 × 10 = 98.1 meters

vertical displacement is s=1/2 at^2 + vt

initial vertical velocity is 0 so s=1/2 at^2

a in this instance is gravitational acceleration so 60m= 1/2 (9.81)t^2

solve for t, t = 3.497s. //I corrected this answer as just now I misread horizontal as vertical.

*For free fall,

Initial velocity (u) = 0

g = 9.8m/s²

time(t) = 10s

Using the second equation of free fall;

s = ut + 1/2gt²

where 's' is the distance fallen.

s = 0(10) + 1/2(9.8)(10)²

s = 1/2(9.8)(100)

s = 490m.

*Initial horizontal velocity (Ux) = 3m/s

Initial vertical velocity (Uy) = 0

since it did not start with any vertical velocity.

Using the second equation of vertical downward motion:

h = Uyt + 1/2gt²

where h is the height of the cliff = 60m.

g = 9.8m/s²

60 = 0(t) = 1/2 (9.8)(t²)

60 = 4.9t²

t = √(60/4.9) = 3.5s.

Question:

What happens to electrical energy that is used by objects in our homes? (1 point)

a It is absorbed by batteries.

b It is destroyed.

c It is stored in solar panels.

d It is transformed into other forms of energy.

Answer:

D

d. It is transformed into other forms of energy.

When electrical energy is used by objects in our homes, it is transformed into other forms of energy depending on the specific device or appliance. For example:

This transformation of electrical energy into other forms is governed by the principles of conservation of energy, which state that energy cannot be created or destroyed, only converted from one form to another. So, while electrical energy is consumed and "used up" by the devices in our homes, it is not destroyed but rather converted into different forms of energy that serve various purposes.
