Answer: 2.5x10^8 kilometers
Explanation:
Given that:
Distance between the earth and the sun = 2.5x10¹¹metres
Convert distance in metres to kilometers
Recall that 1000 metres = 1 kilometers
So, 2.5x10¹¹metres = Z kilometers
To get the value of Z, cross multiply
Z km x 1000 m = (2.5x10¹¹metres x 1km)
1000Z = 2.5 x 10^11
Divide both sides by Z
1000Z/1000 = 2.5 x 10^11/1000
Z = 2.5x10^8km
Thus, the distance between the earth and the sun is about 2.5x10^8km
10. A safe place to use the trebuchet would be away from other buildings and people. A good example of a place would be a large field with no nearby structures.
14. Many factors need to be kept consistent throughout the experiment. One example of a variable that would need to be consistent is the weight and size of the projectile.
15. It is important to do many trials so that you can make sure that the results of each trial are nearly the same. If they are all vastly different, then it means that something has gone wrong.
Sorry I was only able to answer a few questions, but I hope these few answers help! :)
Answer:
a = 2m/s^2
Explanation:
Force (F) = 100 N
Mass (m) = 50 kg
Here,
F = m×a
100 = 50 × a
a = 100÷50
a = 2m/s^2
Thus, the acceleration on the cart is a = 2m/s^2

Between B and C, the object was going at a constant velocity; it is going 60 m/min consistently for that time frame.
