Answer:
Momentum must be conserved in the collision.
The steel block must move faster after the collision to preserve momentum.
If the steel block is moving faster it will aso have more kinetic energy.
(Note; If the bullet hits the steel block it will have some momentum in the reverse direction and thus have a greater change in total momtntum than the bullet that becomes imbedded in the wood block)
Daniel will earn $2.20 more a week because his pay increase will increase his pay from $8 to $8.40
C because you need to order it from fastest to slowest and the least amount of time taken is the fastest.
I don’t know the first one but the second one is light and the third one is a satellite
Answer:
Explanation:
Total heat = Work done = Force × distance
distance = 0.075 × 12 = 0.9 m
W = 45 × 0.9 = 40.5 joules
Specific heat of the human hand = 3.5 kj/kg = 3.5 j/g
Q = MCΔT
ΔT = (Q) ÷ (MC)
ΔT = 40.5 ÷ (3.5 × 1) = 11.57°C
