We have heat lost by water is equal to heat gained by Juice.
Heat exchanged is calculated using the formula,
Let 
be the final temperature then,
The final temperature of the juice is 12.913 K.
Answer:
Force exerted by car on truck will be 6000 N in opposite direction
Explanation:
It is given that mass of the car is one quarter of the mass of the truck
Force exerted by the truck on the car is 6000 N
We have to find the force exerted by car on the truck
According to newtons third law for any action there is equal and opposite reaction
So force exerted by car on the truck will be equal to 6000 N in opposite direction
Answer:
book resting on a shelf has no potential energy relative to the shelf since it has a height of zero meters relative to the shelf. However, if the book is elevated to some height above the shelf, then it has potential energy proportional to the height at which it resides above the shelf.
An object can have both kinetic and potential energy at the same time. For example, an object which is falling, but has not yet reached the ground has kinetic energy because it is moving downwards, and potential energy because it is able to move downwards even further than it already has. The sum of an object's potential and kinetic energies is called the object's mechanical energy.
As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
Another important concept is work.
Answer:
Kinetic Energy = 1/2mv^2
Kinetic Energy = 1/2(150 kg)(20 m/s)^2
Kinetic Energy = 75 kg(400 m/s)
Kinetic Energy = 30000 J
Let me know if this helps!
A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.
