-- IF the meter stick is oriented perpendicular to the direction from
it to you, then it appears 1 meter long to you, but very very skinny.
The Lorentz contraction only applies in the direction of motion.
-- If the length of the meter stick is pointing toward you, then . . .
L = L₀ √ (1 - v²/c²)
= √ (1 - 0.36)
= √ (0.64) = 0.8 meter .
So.......
here,
Mass (m) = 20g
Change in Temperature (ΔT) = 29C-10C
= 19C
Specific Heat Capacity = 0.1 cal/ g C
now, plug the info. into the formula,
specific heat capacity = quantity of heat / (mass * change in temperature)
0.1 = quantity of heat / (20 * 19)
0.1 = quantiy of heat / 380
0.1 * 380 = quantity of heat
38 = quantity of heat
so the granite rock boulder absorbed 38 calories of heat energy from the sun
Answer:
Coulomb's law is:
First, force has units of Newtons, the charges have units of Coulombs, and r, the distance, has units of meters, then, working only with the units we have:
N = (1/{e0})*C^2/m^2
then we have:
{e0} = C^2/(m^2*N)
And we know that N = kg*m/s^2
then the dimensions of e0 are:
{e0} = C^2*s^2/(m^3)
(current square per time square over cubed distance)
And knowing that a Faraday is:
F = C^2*S^2/m^2
The units of e0 are:
{e0} = F/m.
<span>The property of sound that determine its volume is its AMPLITUDE. The amplitude and the volume of the sound are directly varied. Which means that the larger the amplitude, the larger is the volume and the softer it is if the amplitude is smaller. It is not affected by the motion of the sound source so long as the barriers are not breached. </span>
