A meter is 100 meters. So a hundredth of a meter stick is a centimeter.<span />
Answer:
The moun lives 2.198*10^-6 s as measured by its own frame of reference
The Earth moved 648 m as measured by the moun's frame of reference
Explanation:
From the point of view of the observer on Earth the muon traveled 3.53 km at 0.983c
0.983 * 3*10^8 = 2.949*10^8 m/s
Δt = d/v = 3530 / 2.949*10^8 = 1.197*10^-5 s
The muon lived 1.197*10^-5 s from the point of view of the observer.
The equation for time dilation is:
Then:
From the point of view of the moun Earth moved at 0.983c (2.949*10^8 m/s) during a time of 2.198*10^-6, so it moved
d = v*t = 2.949*10^8 * 2.198*10^-6 = 648 m
Force between two charges =
( 1/4πε₀ ) · (Charge #1) · (Charge #2) / (Distance between them)²
in the direction away from each other.
In other words, if the force is positive, the charges are repelling.
If the force is negative, the charges are attracting.
Answer:
east
Explanation:
15km east
_______________
X________
8km west
so you are where the xX is so you are still in the eastward direction
First of all, we need to convert the final angular velocity from rpm (revolutions per minute) to rad/s. Keeping in mind that
We have
the angular acceleration is given by
where
is the initial velocity (in this case, zero), and
is the time needed to accelerate the drill to its final velocity. Using
, we can calculate
