Answer:
Federal Bureau of Investigation (FBI)
Answer: its mechanical energy
Explanation:
<span>ΔE = 0
(m_alum) (c_alum) Δt - (m_water)(c_water) Δt' = 0
(30) (897) (20) - (20)(4186) Δt' = 0
Δt' = 6.42857 °C</span>
Answer:
The answer to the question lies in the character of God. God is either finite or infinite. If God is finite and limited, then God could make a rock He could not lift. If God is unlimited in power, then He could create a rock of any size and weight and still be able to lift it.

Answer:
The momentum of the two-block system is 18 kg-m/s
Explanation:
It is given that,
Mass of block A,
Mass of block B,
Velocity of block A,
Velocity of block B,
(it is moving in opposite direction)
We need to find the momentum of two block system. It is given by the product of mass and velocity for both blocks i.e.


p = -18 kg-m/s
So, the momentum of two block system is 18 kg-m/s. Hence, this is the required solution.
