30 speed of light in the glass
Answer:
Increase in total energy will be equal to the increase in the internal energy i.e 
Joules
Explanation:
Given
Weight of sledge hammer 
kilogram
Speed of sledge hammer 
meter per second
Kinetic energy is equal to half the product of mass and velocity square
Substituting the value of mass and velocity, we get -
It is given that one fourth of the energy is converted into internal energy
One fourth of kinetic energy is equal to
Increase in total energy will be equal to the increase in the internal energy i.e Joules
As of now, the current temperature in Enterprise, Alabama is 58 degrees Fahrenheit. However, it may change based off of the climate and the day. Hope this helped!
Answer:
The mass of the object on the Moon (and anywhere else) is about 30.61kg. Please see more detail below.
Explanation:
Weight is the gravitational force exerted on the object and is a function of mass and gravitational acceleration:
(weight) = (mass) x (gravitational acceleration)
We are to find the mass, knowing the weight on Earth to be 300N:
(mass) = (weight on Earth) / (gravitational acceleration on Earth) = 300N / 9.8 m/s^2 = 30.61 kg
The mass of the object is 30.61kg.
The mass of the object is independent of gravity. Therefore the answer to the question "What is its mass on the Moon" is 30.61kg.
If the question were what is its weight on the Moon, the answer would be
(weight on Moon) = (mass) x (grav.accel. on Moon) = 30.61kg x 1.62 m/s^2 = 49.59N
which is about 1/6 of the object's weight on the Earth.
Potential energy is present in the river water behind a dam.
<h3>How is potential energy defined?</h3>
- Potential energy is a form of stored energy that is dependent on the relationship between different system components.
- When a spring is compressed or stretched, its potential energy increases.
- If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy.
- The object's mass, its mass in relation to some reference points, and the gravitational field it is in all affect the potential energy of the object.
- Joule is the SI unit of potential energy as a result (J)
- As weight and height increase, gravitational potential energy rises.
