Answer:
Explanation:
Given
Mass = m
Time = t
Force = mass × acceleration ..... 1
Where acceleration = velocity/time
Ave Force = m×∆v/∆t
= mv/t
If the point M(0,38) is on the circle then its radio is:
Compute the distance between the center and N:
Because d < r then point N is INSIDE THE CIRCLE.
The electrostatic force between two point charges is given by:
where
is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between them
In our problem, charge 1 is
while charge 2 is
and their distance is
r=5.0 cm=0.05 m
So, the electrostatic force between them is
And the negative sign means the force is attractive, because the two charges have opposite sign.
Answer:
0.73m/s2
Explanation:
The speed at which the passengers move is the final speed of the plane
Hence acceleration = V-U/t; change in velocity and t is time taken. U is the initial velocity which is 0m/s
a = 73-0/100= 0.73m/s2
