Answer:
The answer is A
Explanation:
Work done = mgh
where mass, m = 92kg, g= 9.81, height,h= 325m
Therefore,
W= mgh
W=92*9.81*325
W=293319
W=2.93*10>5
Answer:
a) -3.267 m/s
b) 2.227 m/s
Explanation:
As per the conservation of momentum
m1v1 + m2v2=0
m1= mass of log
m2 = mass of lumber jack
v1 = velocity of log
v2 = velocity of lumber jack
a) Velocity of first log
m/s
b) m1v1 + m2v2 = m3v3
Velocity of log
=
The answer is C. The Right yo a Speedy Trial. I just had that question and I got it right.
Answer:
Conduction
Explanation:
"Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules."
The heat in your hand melts that chocolate, making it conduction.
