Answer:
<span>C) Both have rocky composition
Explanation
Earth has rocks. Many many rocks.
It is made of many type of rocks such as </span>sedimentary<span>, </span>metamorphic<span>, and </span><span>igneous rocks. and guess what a asteroid is? That is right ! A ROCK.
</span>A asteroid is normally made of <span>stony silicate rocks , but not always , sometimes I can be diamonds!! The point is , they both are rocks floating around space.</span><span>

Answer:
Mass and Acceleration
Explanation:
The typical Force equation is:
F = ma
where m = mass, and a=acceleration.
Answer:
3300J
Explanation:
Work done is the energy that is lost by the skater
Formula for workdone = 1/2*mV^2
m = 66kg
V = 10m/s
Work done = 1/2 * 66 * 10^2
= 3300J
Answer:
The momentum of bath cars is 40000 Ns which make the difficulty to stop each car in aspect of fprce is the same.
Explanation:
Momentum (P) =mass(m) × velocity (v)
For car A,
P = m × v = 1000 × 40 = 40000 Ns
For car B,
P = m × v = 4000 × 10 = 40000 Ns
Force (F) = Momentum change(ΔΡ)/ time taken(t)
F = ΔΡ/t
When stopping the car the momentum changes from 40000 Ns to 0
So momentum change in both cars is the same. So to stop the two cars in a given time (t) you need the same force, which means you will feel same difficulty.
