The mass of an object is 201 g the object requires 150j to raise its temperature by 100°c. what is the specific heat of the object?
7.46 j/kg-k
0.00130 j/kg - k
3,020,000 j/kg . k
1500 j/kg . k

its c its is a mixture of gases

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
