Answer:
60,000m
Explanation:
Convert km/h to m/s by multiplying with 1000/3600.
Convert hours to seconds by multiplying with 3600.
Because displacement is a vector quantity and deals with the shortest distance between points, simply plug it into the equation s=vt.
It's B lol they are being forced apart but can't move because the are tied down
Since it was dropped, it should be the speed of gravity which is 9.8 meters/second
Answer:
PART A
It is always zero
PART B
Answer is : 0
Explanation:
PART A :It is always zero because according to my research, The net electric field inside a conductor is always zero. If the net electric field were not zero, a current would flow inside the conductor. This would build up charge on the exterior of the conductor. This charge would oppose the field, ultimately (in a few nanoseconds for a metal) canceling the field to zero.
PART B: You already know that there is a zero net electric field inside a conductor; therefore, if you surround any internal point with a Gaussian surface, there will be no flux at any point on this surface, and hence the surface will enclose zero net charge. This surface can be imagined around any point inside the conductor with the same result, so the charge density must be zero everywhere inside the conductor. This argument breaks down at the surface of the conductor, because in that case, part of the Gaussian surface must lie outside the conducting object, where there is an electric field.
Answer:
The water will rise to a height, H = 10.20 m
Given:
Atmospheric Pressure, P =
density of water,
Solution:
The water in the tube will rise to the point where the weight is balanced by the force as a result of the atmospheric pressure.
Therefore,
Pressure, P =
where
g = acceleration due to gravity = 9.8 m/s
H = height of water in the tube
Now,
Putting the values in the above formula:
H = 10.20 m
