Answer:
0.72 kg per cubic m
Explanation:
Mass = 14.4 kg
Volume = lbh = 4*1*5 = 20 cubic m
Answer:
it would be 12/A
Explanation:
if you dived 5 by 12 youll get 60 and you cant get 60 y anything else in there so therefor its 12 :)
<span>AS T1,T2,T3 are the tensions in the ropes,assuming that there are Three blocks of mass 3m, 2m, and m.T3 is the string between 3m and 2m,T2 is the string between 2m and m ,T1 is the string attached to m thus T1 pulls the whole set of blocks along, so it must be the largest. T2 pulls the last
two masses, but T3 only pulls the last mass, so T3 < T2 < T1.</span>
Answer:
I need an image, but if you're talking about Potential and Kinetic energy, I will determine for you:
Explanation:
Potential Energy: stored energy that depends upon the relative position of various parts of a system.
Kinetic Energy: the form of energy that an object or a particle has by reason of its motion.
Therefore, if the skier is on top of the mountain, they would have potential energy since their energy from the ground to the top of the surface is stored. But, if the skier is in motion/mid-air from the top of a mountain, their energy is kinetic (in motion) because their stored energy (potential) is released as they step off of the surface.
Answer:
179.47m/s
Explanation:
Using the law of conservation of momentum
m1u1 + m2u2 = (m1+m2)v
m1 and m2 are the masses
u1 and u2 are the initial velocities
v is the final velocity
Substitute
7750(179)+72(230) = (7750+72)v
1,387,250+16560 = 7822v
1,403,810 = 7822v
v = 1,403,810/7822
v= 179.47m/s
Hence the final velocity of the probe is 179.47m/s
