Answer:
The kinetic energy of the ball when it leaves the gun is equal to 5 J.
Explanation:
It is given that, a child does 5.0 J of work on a spring while loading a ball into a spring-loaded toy gun. We need to find the kinetic energy of the ball when it leaves the gun when the mechanical energy of the system is conserved.
Mechanical energy is equal to the total energy of the system. It remains conserved due to the law of conservation of mechanical energy.
So, the kinetic energy of the ball when it leaves the gun is equal to 5 J. Hence, this is the required solution.
Answer:
The warm seas create a large humid air mass. The warm air rises and forms a low pressure cell, known as a tropical depression.
Explanation:
Hurricanes arise in the tropical latitudes (between 10 degrees and 25 degrees N) in summer and autumn when sea surface temperature are 28 degrees C (82 degrees F) or higher.
Answer:
5,760
Explanation:
1 minute is equal to 60 seconds. so you will multiply 60 times 96. and that equals 5,760
Answer:
The new gravitational force will be of 4.5 units
Explanation:
Recall that the formula for the gravitational force between two objects of masses m1 and m2 separated by a distance d is given by:
in our case, we are told that such gives 72 units of force:
Then we change the distance between the objects to 4 times the original (4 * d), such will produce a new gravitational force Fg':
Therefore the new gravitational force would be of 4.5 units
