Weight on any planet is (mass) x (acceleration of gravity there).
Acceleration of gravity on Earth is about 9.8 meters per second² .
So weight of 50 kg on Earth is (50 x 9.8) = <u>490 newtons</u>.
(That's about 110.2 pounds.)
Explanation:
The speed of light is 300,000,000 m/s. There are 8 zeros, so in scientific notation, the speed is 3×10⁸ m/s.
Answer:
they are found in a nucleus
Explanation:
Answer:
-5.9 rad/s^{2}
Explanation:
radius (r) = 30 cm = 0.3 m
mass (m) = 1.05 kg
initial speed (u) = 77 rpm
final speed (v) = 0 rpm
time (t) = 1.37 s
angular acceleration =
therefore
initial speed (U) = 77 rpm = 77 x (2π/60) = 8.06 rad/s
final speed (v) = 0 rpm = 0 rad/s
angular acceleration =
= -5.9 rad/s^{2}
Answer: uhhhhhhh what is this for?
