Answer:
15.29m/s
Explanation:
Using the law of conservation of momentum
m1u1+m2u2 = (m1+m2)v
m1 is the mass of the clown = 85kg
u1 is the velocity of the clown = 0m/s (fired out from rest)
m2 is the mass of the cannon = 480kg
u2 is the velocity of the cannon = 18m/s
Let v me the recoil speed of the cannon
Substitute into the formula
85(0)+480(18) = (85+480)v
0+8640 = 565v
v = 8640/565
v = 15.29m/s
Hence the recoil speed of the cannon is 15.29m/s
Answer:
nuclear fusion
<h3>The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.</h3>
And the answer is False.
It will help you.
False because that would not matter cause we all weigh different weights
C = Q/V, and since C is a constant, if voltage is doubled, charged will be doubled as well. Therefore charge will be 2Q
