All charged objects create an electric field around them. What two factors determine the strength of two electric fields upon the charged objects creating them?

Answers

Answer 1

Answer: -- The product of the magnitudes of the two charges.
-- The distance between the centers of the two charges.

The signs of the charges ... whether their signs are the same
or opposite ... determines the direction of the forces, but not
their magnitude.

Krista and Blaire are identical twins that were separated at birth. Both of the girls are scared of thunder when they are young. Krista's adoptive parents teach her to deal with her fear by pretending that the thunder is a big drum in an orchestra. Blaire's adoptive parents, on the other hand, teach her to deal with her fear of thunder by thinking about sunny days ahead.Both girls have inherited a fear of thunder. The difference in their way of dealing with this fear, however, can best be explained by differences in their _______.
1 . A farmer moves along the boundary of his rectangular field of side 10m x 20m . farmer covers 1m in 1sec . what will be the magnitude of displacement at the total distance travelled.2 . Rahul pedals his cycle from rest. Pedals his cycle to get a velocity of 10 ms-1 in 30 seconds. then he applies brakes in such that the velocity of the cycle comes does to 6 ms-1 in next 5 seconds . calculate the acceleration and deceleration .

Consider the car driving around a circular track. Once started, the driver maintains a speed of 45 m/h. Compare the driver's velocity with his acceleration in this case.A) The car is accelerating because it is changing direction but the velocity is
constant.
B) The car is traveling at a constant rate of speed so it is not accelerating and
the velocity does not change.
C) Acceleration is the change in velocity so the car is experiencing a change
in velocity and it is accelerating.
D) The car is traveling at a constant rate of speed so it is not accelerating but
the velocity changes because the direction the car travels is constantly
changing

Answers

Answer:

B) The car is traveling at a constant rate of speed so it is not accelerating and the velocity does not change.

Explanation:

Since the driver is maintaining his speed, therefore velocity is constant and there is no acceleration because acceleration is the rate of change of speed with time.

Starting from rest, Christina experiences 24.5 m/s2 of acceleration to take off from an aircraft carrier for 5 seconds. How long does the runway need to be? Round to the nearest meter.

Answers

Answer:

The length of the runway to the nearest meter is 306 m.

Explanation:

Given:

Initial velocity of Christina is, $u=0\ m/s(Rest)$

Time taken is, $t=5\ s$

Acceleration experienced by Christina is, $a=24.5\ m/s^2$

The length of the runway is, $d=?$

Now, we use Newton's equation of motion that relates the distance, initial velocity, time and acceleration.

So, we have the following equation of motion:

$d=ut+(1)/(2)at^2$

Plug in all the given values and solve for 'd'. This gives,

$d=0+(1)/(2)* 24.5* 5^2\n\nd=(1* 24.5* 25)/(2)\n\nd=(612.5)/(2)\n\nd=306.25\approx 306\ m(\textrm{Rounding to nearest meter})$

Therefore, the length of the runway to the nearest meter is 306 m.
