The heavier one. The explanation for this is that <span>momentum is directly proportional to mass. The more mass there is, the more momentum.
This is as simply as I could explain it, hope I helped :) </span>
Answer:
velocity
a). 
direction
b).
kinetic energy
c).
Explanation:
Those kind of question have two typical questions inside to response the final velocity and the direction finding the angle and finally the kinetic energy so each the information you need can find there so
a).

solve to vf






b).

solve to β



c).
Final kinetic energy



Answer:
k=0.0577w/mk
k=0.03338BTU/h-ft-ºF
Explanation:
First we use the equation for heat transfer by conduction and solve for K
Q=KA(T2-T1)/x
Where
q=heat
A=area
T=temperature
K=conductivity
x=thickness
solving for k
k=Qx/A(T2-T1)
Q/A=Heat flux=q
k=qx/(T2-T1)
k=35.1*0.025/(318.4-303.2)
K=0.0577w/mk
remember that 1 btu / hftk equals 1,729 w / mk
K=0.0577/1.729=0.03338BTU/h-ft-ºF
The dark spots on the moon are the craters and there light spots are made up of the moon dust technically called regolith
