Answer:

Option B

Explanation:

Displacement = Area under the velocity-time graph

So to find the displacement of a particle from 7 to 8 seconds we take the triangle and calculate its area.

$Area\ of\ a\ right\ angled\ triangle = \frac{1}{2}*(base)*(height) \\\\Area\ of\ a\ right\ angled\ triangle = \frac{1}{2}*(1)*(3) \\\\Area\ of\ a\ right\ angled\ triangle = 1.5$

So the displacement is 1.5 meters

I have an uploaded image so you can understand it better hope it helps

A cow is given a growth hormone and then compared to another cow that was not given a growth hormone. Both cows were weighed at

igomit [66]

The complete question is as follows:

A cow is given a growth hormone and then compared to another cow that was not given a growth hormone. Both cows were weighed at 2 years. What is the independent variable?

if the cow is given growth hormone or not

weight of the cow

same cows

type of growth hormone

Answer:

The correct answer is - if the cow is given growth hormone or no

Explanation:

The independent variable is here is if the growth hormone is given or not as the variable which is subject to change or manipulated during an investigation and affects the dependent variable is known as the independent variable.

Due to this independent variable manipulation the weight of the cows might be different which makes the weights as the dependent variable.

If a motorcyclist accelerates from rest to 40 m/s in 8 seconds, what is their acceleration?

IgorC [24]

Answer:

5 m/s²

Explanation:

Given:

v₀ = 0 m/s

v = 40 m/s

t = 8 s

Find: a

a = (v − v₀) / t

a = (40 m/s − 0 m/s) / 8 s

a = 5 m/s²

A man tries to push a 200 kg Car that moves at a acceleration 0.50 m/s2. The man is able to displace the car 10 m. How much work

yawa3891 [41]

The work done by the man pushing the car over the given distance is 1000J.

Given the data in the question;

Mass of car; $m = 200kg$

Acceleration of the car; $a = 0.5m/s^2$

Distance covered by the car; $d = 10m$

Work done; $W = \ ?$

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

$Work\ done = f * d$
