Answer:
Explanation:
We are asked to find the potential energy of a bowling ball.
Potential energy is the energy an object possesses due to its position. It is calculated using the following formula.
In this formula, m is the mass, g is the acceleration due to gravity, and h is the height.
The bowling ball has a mass of 2 kilograms. The hill is 5 meters high. Assuming this situation is occurring on Earth, the acceleration due to gravity is 9.8 meters per second squared.
- m= 2 kg
- g= 9.8 m/s²
- h= 5 m
Substitute the values into the formula.
Multiply the numbers together.
Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. Our answer of 98 kg*m²/s² is equal to 98 Joules.
The bowling ball has <u>98 Joules of potential energy.</u>
Answer:
0.136 C
Explanation:
This question uses the simple idea of conservation of energy. We work with the assumption that energy loss is zero
At the top of the waterfall the water has maximum potential energy
Where
= Mass of water
= Acceleration due to gravity
= Height
Now at the bottom just before impact all of the potential energy is converted to kinetic energy and right after impact all this kinetic energy is converted to thermal energy ()
Where
= Mass of water
= Specific Heat Capacity of Water
= Change in Temperature
Equating the two equations
Since the value of is a constant, it is equal to 4186 J / (kg * C). We input all the given values into the equation and find the answer
The capacity of something to be flattened or reduced in size by pressure.
