Answer:
1.63103 seconds
Explanation:
= Actual period of clock = 1 second
v = Speed at which the observer is moving = 0.79 c
c = Speed of light =
Time dilation is given by
The period is 1.63103 seconds
Answer:
Explanation:
The weight of the bee is:
with m the mass and g the gravity acceleration.
Electric force of the bee is related with the electric field of earth by:
with q the charge, E the electric field and Fe the electric force.
So:
Because Newton's first law we should make the net force on it equals cero:
with W the weight, Fe the electric force on the bee due earth's electric field and F the force.
So, the applied electric field should be:
The negative sign indicates that the electric field should be opposite to earth's electric field, so it should be upward.
Weather balloons are filled with only a small amount of helium because the __Volume__. of the balloon will increase as the air pressure decreases at higher altitudes.
