Answer:
Saturn is mainly composed of the lightest two gases known, hydrogen and helium. It is the only planet in our solar system whose density is less than water.
Explanation:
Answer:
Perfectly inelastic collision
Explanation:
There are two types of collisions:
- Elastic collision: in an elastic collision, the total momentum of the objects before and after the collision is conserved; also, the total kinetic energy of the objects before and after the collision is conserved.
- Inelastic collision: in an inelastic collision, the total momentum of the objects before and after the collision is conserved, while the total kinetic energy is not. In fact, part of the total kinetic energy of the objects is lost during the collision, converted mainly into thermal energy (or other forms of energy) due to the presence of frictional forces.
- A particular type of inelastic collision is called perfectly inelastic collision: this occurs when the two objects stick together after the collision. In this case, the maximum amount of kinetic energy of the system is lost.
As we know that mechanical advantage is defined as the ratio of output force and input force for the pulley system
Here we know that it required 10 lb of input force in order to lift the block of 500 lb so here output force is 500 lb
now we have
here we have
now from above formula we have
so mechanical advantage of this system is 50
Need Height and Mass, since Gravitational Potential Energy is equal to mgh. Not really sure what you’re asking though. Please elaborate and I can give a better answer!
<u><em>Part 1:</em></u>
<u>The basics of conversions state that:</u>
1 ml is equivalent to 1 cm³
This means that the ratio between them is 1:1
Therefore, 200 ml of water would be equivalent to 200 cm³ of water
<u><em>Part 2:</em></u>
<u>Again, the basics of conversion states that:</u>
1 ml is equivalent to 1 * 10⁻⁶ m³
We will use cross multiplication to convert 200 ml to m³ as follows:
1 ml ................> 1 * 10⁻⁶ m³
200 ml .........> ??
200 ml = 
m³
Hope this helps :)
