It would fall at about/ around 96 mph
<span>1. Turning on the light converts electrical energy to light energy. 2. The ball sitting on the floor has a potential energy [energy at rest], kicking the ball converts its potential energy to kinetic energy, which is energy in motion. 3. MP 3 player uses batteries which possess chemical energy, the chemical energy is converted to sound energy when the player was turned on. 4. When the fan was turned on, the electrical energy which powered the fan was converted to mechanical energy which makes the fan blades to rotate. 5. The candy bar possesses chemical energy which was converted to mechanical energy in the eater which make it possible for him to perform the mechanical work of dancing.</span>
A chemical compound consists of 2 or more chemical elements. They can be separated into simpler substances. Atoms of elements can be combined to form compounds. Molecules are groups of 2 or more atoms held together by chemical bonds. Minerals are chemical compound that can be found in nature. Valence is a measure of the combining power of an element.Answer: A. Atoms of elements.
Answer: The speed is 15.5 m/s
Explanation:
The kinetic energy can be written as:
K = (1/2)*m*v^2
where m is the mass and v is the speed.
Then we have that:
18 j = (1/2)*0.15kg*v^2
Now we solve this for v.
√(18*2/0.15) = v
15.5 m/s = v
The change in momentum of the ball is 0.6Kgm/s.
To find the answer, we need to know about the momentum.
<h3>What's the expression of change in momentum during collision?</h3>
- The change in momentum= final momentum - initial momentum of the objects
- And momentum= mass × velocity
<h3>What's the change in momentum here?</h3>
- Here the initial momentum= 0.10×30=3Kgm/s
- Final momentum= 0.10×24= 2.4Kgm/s
- Change in momentum= 3-2.4= 0.6Kgm/s
Thus, we can conclude that the change in momentum is 0.6Kgm/s.
