Answer:
as it travel through the space it behave like a wave and has an oscillating electric field components and an oscillating magnetic field
Let N be the normal force that forces the person against the wall.
Then u N = m g is the frictional force supporting the person's weight
and N = m g / u
also, N = m v^2 / R is the normal force providing the centripetal acceleration
So, m g / u = m v^2 / R
v^2 = g R / u
since v = 2 pi R T
4 pi^2 R^2 T^2 = g R / u and T^2 = g / (4 u pi^2 R)
T = 1/ (2 pi) (g /(u R))^1/2 = .159 * (9.8 m/s^2 / (.521 * 4.4 m)) ^1/2
T = .68 / s
Do you see any thing wrong here?
T should have units of seconds not 1 / seconds
v should be 2 * pi * R / T where T is the time for 1 revolution
So you need to make that correction in the above formula for v.
rest is the state of a body which is stationary relative to a particular frame of reference or another object. When the state of a body does not changes with time with respect to its surroundings in a particular frame of reference that time it is said to be at rest.
in other words we can say that when a body has zero velocity and its position is not changing with time relative to its surrounding then it is said to be at rest.
For example a chair on which you are sitting is at rest or a table on which your desktop is kept is rest because its position is not changing.
<span>Closing ratio is the number of deals you close compared to the number of presentations ( or calls ) you make. In this case it means: 1 sale : 3.5 calls ( average ). We will use proportions: 1 : 3.5 = 23 : x. x = 23 * 3.5, x = 80.5. We have to round this number upwards to be more certain that you get the 23 sales. Answer: 81 calls </span>
As long as the moon orbits the Earth in the same way, the phases will be the same.
