Answer:
1. The car which is twice as massive as the other will have twice potential energy.
Explanation:
The potential energy of an object is given by:
where
m is the mass of the object
g is the gravitational acceleration
h is the height of the object measured to some reference level
In this problem, we have two cars at same elevation (= same h in the formula) but one car has twice the mass of the second car. Calling m the mass of one car and 2m the mass of the second car, we have:
- Potential energy of the first car:
- potential energy of the second car:
So, the car which is twice as massive as the other will have twice potential energy.
Answer:
If a vertical line extending down from an object's CG extends outside its area of support, the object will topple
Explanation:
We can understand better this situation using a diagram with the forces acting on it.
In the attached image we can see that when the gravity center is bouncing outside from the area of the pedestal, the object will be out of balance and will fall.
Technically, they do have a skeleton. The hard shell it has is called an exoskeleton. It works just like our skeleton, in terms of muscles and support. And, it protects from harm, similar to the way our skin protects the inside of our body from dirt and such.
Answer:
no

so basically I am domb so I can not help you
Liquid to a gas hence the name water vapor
