Answer:

3) 52.5 m

Explanation:

d = v₁t + 1/2at²

d = 16 m/s (5s) + 1/2(-2.2m/s²) (5s)²  = 52.5 m

The car travels for 52.5m during the 5 seconds interval

In order to get the distance traveled by car, we will use the equation of motion. The equation of motion for calculating the distance is expressed as:

[tex]S = ut+\frac{1}{2}at^2[/tex]  where;

Given the following parameters

u = 16m/s

a = -2.20m/s²

t = 5secs

Substitute the given values into the expression as shown:

[tex]S = 16(5)+\frac{1}{2}(-2.20)(5)^2\\S=80-1.10(25)\\S=80-27.5\\S= 52.5m[/tex]

Hence the car travels for 52.5m during the 5 seconds interval.

This question is about matching each definition with its correct term. Please find the term matched with their appropriate definition below.

Explanation:

1. Empirical evidence: An empirical evidence is an observational evidence i.e an evidence gathered by observation or use of senses.

2. Dependent variable: Dependent variable is an experimental factor that changes in response to a change in the independent variable. In other words, it is dependent on the independent variable.

3. Applied research: Applied research is a type of research oriented at solving a present problem or need. It encompasses the production of products that can be sold for profit.

4. Hypothesis: A hypothesis in an experiment is a proposed explanation for a scientific problem that itself can be tested by experimentation. A hypothesis aims at providing a testable explanation to an observed problem.

5. Control: A control is a quantity in an experiment that remains unchanged or constant. It is kept the same by the experimenter for all groups in the experiment in order not to influence the outcome.

6. Basic research: Basic research is the research that expands knowledge in a particular area. It is the kind of research that aims at filling a knowledge void or satiating curiosity.

7. Independent variable: The independent variable is the experimental factor that is changed or manipulated deliberately by the scientist.

Answer:

The displacement and the distance were equal early in the run, however due to the shape of the track the distance is greater than the displacement.

m = 4.3 kg

Hi there !

use formula

G = m×g => m = G/g

g ≈ 10N/kg

replace G ; g

m = 43N/(10N/kg)

m = 4.3 kg

Good luck !

freezing

During freezing, the temperature of a substance remains constant while the particles in the liquid form a crystalline solid. Because particles in a liquid have more energy than particles in a solid, energy is released during freezing. This energy is released into the surroundings.

Answer: -11 m/s^2

Explanation: 22/2, it went to a full stop so it’s negative

The acceleration will be "-11 m/s²".

According to the question,

Time,

Initially traveling,

Full stop means,

As we know, the formula:

→ [tex]V = at +V_0[/tex]

By substituting the values, we get

→ [tex]0 = a\times t+V_0[/tex]

→ [tex]0 = a\times 2+22[/tex]

→ [tex]2a = -22[/tex]

→   [tex]a = -\frac{22}{2}[/tex]

→      [tex]= -11 \ m/s^2[/tex]

Answer:

Answer:

Explanation:

Velocity is the change of displacement of a body with respect to time.

Velocity = Displacement/Time

Displacement = Δv * Δt

From the graph, it can be seen that the object sliding along the horizontal has a velocity of 0m/s since it starts travelling when v = 0m/s

For the time;

Δt =t2-t1

Δt = 8-0

Δt = 8s

object's displacement = 0 * 8

Hence the object displacement is 0m

Answer:

The answer is below

Explanation:

a) Since the 24 N weight feeder creates a tension of 480 N on either side of the rope. Taking into consideration of one side of the rope, this means that 24/2 = 12 N creates a tension of 480 N for a length of 2 m (4/2).

Therefore, Fg = 12 N, F = 480 N

sin θ = Fg/F

sin θ = 12 / 480

sin θ = 0.025

θ = sin⁻¹ (0.025)

θ = 1.43⁰

Let the rope sag be h, hence:

tanθ = h/2 m

h = 2 m * tan (1.43)

h = 0.05 m

b) If the bird lands on the feeder, because of the birds weight, the tension on each side of the road would increase.

Answer:

Explanation:

If a small piece of Styrofoam packing material is dropped from a height of 1.90 m above the ground and reaches a terminal speed after falling 0.400m, the Change in distance will be 1.90m - 0.400 = 1.50m

If it takes 5.4secs fo r the Styrofoam to reach the ground, the terminal velocity will be expressed as;

Vt = change in distance/time

Vt = 1.5m/5.4s

Vt = 0.28m/s

Note that the Styrofoam reaches its final velocity when the acceleration is zero.

To get the constant value B from the equation a = g-Bv

a = 0m/s²

g = 9.81m/s²

v = 0.28m/s

Substituting the parameters into the formula.

0 = 9.81-0.28B

-9.81 = -0.28B

Divide both sides by -0.28

B = -9.81/-0.28

B = 35.04

b) at t = 0sec, the initial terminal velocity is also zero.

Substituting v = 0 into the equation to get the acceleration.

a = g-Bv

a = g-B(0)

a = g

Hence the acceleration at t =0s is equal to the acceleration due to gravity which is 9.81m/s²

c) Given speed v = 0.150m/s

g = 9.81m/s²

B = 35.04

Substituting the given data into the equation a = g-Bv

a = 9.81-35.04(0.15)

a = 9.81 - 5.26

a = 4.55m/s²

Answer:

a

    [tex]v  =  0.28 \  m/s  [/tex]

b

    [tex]a =  9.8  m/s^2[/tex]

c

[tex]a = 4.55 \ m/s^2[/tex]

Explanation:

From the question we are told that

The fall height is [tex]h = 1.90 \ m[/tex]

The magnitude of the acceleration is [tex]a = g -Bv[/tex]

The height at which terminal speed is attained is [tex]h_t = 0.400 \ m[/tex]

The time taken to reach the ground from the terminal velocity height is t = 5.40 s

Generally the height which object traveled with terminal velocity is

[tex]H = h- h_t[/tex]

=> [tex]H = 1.90 - 0.400[/tex]

=> [tex]H = 1.50 \ m [/tex]

Generally the terminal velocity is mathematically represented as

[tex]v = \frac{H}{t}[/tex]

=>        [tex]v  =  \frac{1.50}{5.40}[/tex]

=>       [tex]v  =  0.28 \  m/s  [/tex]

Generally at terminal velocity , acceleration is zero  so

       [tex] g -Bv = 0 [/tex]

substituting

       [tex]9.8 \ m/s^2[/tex]

=>    [tex] 9.8 -B (0.28) = 0 [/tex]

=> [tex] v = 35 \  m/s  [/tex]

Generally at t =  0 s the velocity v = 0  (That no motion at time zero)

So  from acceleration equation

    [tex]a =  9.8  -35(0)[/tex]

=>   [tex]a =  9.8  m/s^2[/tex]

Generally when the speed v  =  0.150 m/s

The acceleration is

      [tex]a =  9.8  -35(0.150)[/tex]

=>    [tex]a =  4.55 \  m/s^2[/tex]

I just did this problem so I promise you my answer is correct the total momentum of the system is 1717.

Explanation:

What you do is find the momentum of the first object which is simple enough 202(8.5) which equals 1717 and an object at rest will have no momentum which is shown when you have to plug in a 0 for velocity and multiply you get zero. Then to find the total you just add 1717+0 which obviously gives you 1717.

Because it is above the Earth's atmosphere. The atmosphere disturbs the starlight (a bit like looking through water) and blurs the images. So Hubble's images are much sharper than those from other telescopes.

Explanation:

Answer:

Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detailed visible light images, allowing a deep view into space.

To prove:

v^2 =u^2 + 2as

we have,

a = v-u/t

or, t= v- u/a......(i)

Again,

s = u + v /2*t...........( ii )

Substitutung the value of 't' from equation (i) in equation ( ii ) , we have,

s= (u+v/2) * ( v- u/a)

or, s=(v^2 - u^2) /2a

or, 2as = v^2 - u^2

therefore,

v^2= u^2 + 2as

Answer:

[tex]Direction= 119.74^\circ[/tex]

Explanation:

Displacement Vector

The displacement, as every vector, has a magnitude r and a direction angle θ measured from the positive x-axis.

If we know the x-y components of the displacement, the magnitude and angle can be calculated by the equations:

[tex]r=\sqrt{x^2+y^2}[/tex]

[tex]\displaystyle \tan\theta=\frac{y}{x}[/tex]

The coordinates of the given vector are x=-12 m, y=21 m, thus:

[tex]\displaystyle \tan\theta=\frac{21}{-12}=-1.75[/tex]

[tex]\theta=tan^{-1}(-1.75)=-60.26^\circ[/tex]

Since the vector lies in the second quadrant, we add 180° to find the correct direction:

[tex]\boxed{Direction=-60.26^\circ+180^\circ= 119.74^\circ}[/tex]
