This is what e=mc² means.
So rest energy is RH side of equation that is its mass times speed of light squared.
The Coriolis effect influences wind direction around the world in this way: in the Northern Hemisphere it curves winds to the right; in the Southern Hemisphere it curves them left. The exception is with low pressure systems. ... This happens simply because the Earth is a sphere and would be true if the Earth didn't rotate.
The change in velocity is 10 m/s in 5 seconds.
sinces a = change in velocity/time
a= 10/5
a=2
Given:
ΔT = 38 - 26 = 12°C, temperature change
Q = 11.3 J, heat input
c = 0.128 J/(g-°C), specific heat of lead
Let m = the mass of the lead.
Then
Q = m*c*ΔT
(m g)*(0.128 J/(g-°C))*(12 °C) = 11.3 J
1.536m = 11.3
m = 7.357 g
Answer: 7.36 g (2 sig. figs)
Answer:
71.42857 kgm²
1311.81946 kg
5.082 rad/s
Explanation:
F = Force = 200 N
R = Radius = 0.33 m
= Angular acceleration is 0.924 rad/s²
Moment of inertia is given by
The moment of inertia of the wheel is 71.42857 kgm²
Moment of inertia of a solid cylindrical wheel is given by
The mass of the wheel is 1311.81946 kg
Rotational impulse is given by
Also
The angular speed is 5.082 rad/s
