Answer:
4748.4
Explanation:
The first number after the decimal is the tenths place and when it says round it means look at the number after it and if it's above four then raise the tenths place by one.
Answer:
zero
Explanation:
For a solid conducting sphere, charges are present on the surface of the sphere due to a phenomenon known as electrostatic sheilding. This affects the charge present in the body and makes it zero. However, the electrostatic potential appears to be equal to the whole present point that shows on the surface. The surface of a spherical conducting solid sphere is known as an equipotential surface. Thus, the potential difference between the two opposite points on the surface of the sphere will also be zero.
To solve this problem we will use the concepts related to thermal expansion in a body for which the initial length, the coefficient of thermal expansion and the temperature change are related:
Where,
= Change in Length
= Coefficient of linear expansion
= Change in temperature
= Initial Length
Our values are:
Replacing we have,
Therefore the change in milimiters was 0.4126mm
The inner planets have atmospheres that are able to sustain weather. all of them have rift valleys and volcanos. out of all the inner planets, mercury is the smallest and the hottest planet because of its closeness to the sun.
The amplitudes are subtracting which is when one has a peak (high point) and one has a trough (low point) This cancellation is called destructive interference
