27% helium and 71% hydrogen
Example? I see none, so I'll make up my own.
An example of kinetic energy, is like bicycle riding down a hill.
Kinetic energy, is basically <em>moving</em> energy.
Hope this helps!!!:)
Answer:
63N, 45N
Explanation:
Given:
Tension 1 = T1
We have the following free body equations:
F - T1 = 100*0.3 -(I)
T1 - T2 = 60*0.3 -(II)
T2 = 150*0.3 -(III)
Adding the three above equations, we have
F - T1 + T1 - T2 + T2 = (100*0.3) + (60*0.3) + (150*0.3)
Hence, F = 93N
Hence, substituting into equation I we have
T1 = Force by bar on lighter cart = 93 - (100*0.3) = 63N
Hence, force that heavier cart exerts on bar
T2 = 150*0.3 = 45N
C.an equal and opposite reaction
Answer:
4750000 J
Explanation:
Kinetic Energy= 1/2* mass* velocity²
1/2*950*100²=4750000
