gravity is less on the moon than it is here on earth
Answer:
A.) Size of the charge
B.) Distance
Explanation:
From the expression for electric field intensity due to a point charge
E= Q/4πεr²
Where Q is the charge
r= is the distance
ε= permittivity of free space
From the formula we see that the Electric field E is a function of charge and distance.
What is electric field?
Electric field is a region around an electric charge where an electric force is experienced by other charges.
There is only one possible state: constant uniform motion. That means constant speed in a straight line.
(If the constant speed happens to be zero, this description also covers the case where the object isn't moving. That special case is called "at rest".)
Answer:
Explanation:
Velocity will be zero when the derivative of position is zero.
Set the origin at the ground with UP as the positive direction
The equation with the known information included is
h = -16t² + 112t + 0
h' = -32t + 112
0 = -32t + 112
32t = 112
t = 112/32
t = 3.5 s
I):final velocity=initial velocity+acceleration due to gravity*time of travel
Therefore,
v=0+9.8*3.1
=30.38 m/s
If by floor you meant water bed then i think there isn't enough info in the question.
