Answer:
The change in momentum experienced by the bowling ball is 96 kgm/s.
Explanation:
Given;
mass of the bowling ball, m = 12 kg
velocity of the bowling ball, v = 8 m/s
time of motion, t = 10 s
The change in momentum experienced by the bowling ball is equal to the impulse experienced by the bowling ball.
ΔP = J = F x t

Therefore, the change in momentum experienced by the bowling ball is 96 kgm/s.
Answer:
r = 1.56 m
Explanation:
B = μ₀I/2πr
r = μ₀I/2πB
I = 9.00 / 52.0 = 0.173 A
μ₀ = 4πe-7 T•m/A
r = 4πe-7(0.173)/2π(2.22e-8)
r = 2e-7(0.173)/(2.22e-8)
r = 1.5592... ≈ 1.56 m
Answer:
after 6 second it will stop
he travel 36 m to stop
Explanation:
given data
speed = 12 m/s
distance = 100 m
decelerates rate = 2.00 m/s²
so acceleration a = - 2.00 m/s²
to find out
how long does it take to stop and how far does he travel
solution
we will apply here first equation of motion that is
v = u + at ......1
here u is speed 12 and v is 0 because we stop finally
put here all value in equation 1
0 = 12 + (-2) t
t = 6 s
so after 6 second it will stop
and
for distance we apply equation of motion
v²-u² = 2×a×s ..........2
here v is 0 u is 12 and a is -2 and find distance s
put all value in equation 2
0-12² = 2×(-2)×s
s = 36 m
so he travel 36 m to stop
Answer:
49 kg is the mass of the couch.
Explanation:
GPE = mgh
9800 = m * 10 * 20
9800 = 200m
m = (9800/20) = 49 m
Thenks and mark me brainliest :))
Alpha particles, because they are the heaviest ones (helium nuclei) and will travel around the body.
