Answer:
F = 0N
Explanation:
The force between two charges is given by

where r is the distance between the charges and K is the Coulomb's constant
(k=8-89*10^9Nm^2/C^2)
The force in the first charge is only the sum of the forces due to the other charges. Hence we have


Ft=0N

Answer:
- your body moving forwards when sudden brakes/force is applied e.g. sudden braking in a car
- feeling a backwards force when something moves quickly from rest e.g a bus
- when you stir a cup of tea, it continues to swirl for a short period of time even though you have stopped
- when shaking a tree, it's leaves or fruit fall down
- satellites which move due to the inertia of motion
hope this helped :)
Answer:
1331.84 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 0
s = Displacement = 490 km
a = Acceleration
g = Acceleration due to gravity = 1.81 m/s² = a
From equation of linear motion

The speed of the material must be 1331.84 m/s in order to reach the height of 490 km
Answer:
proton
Explanation:
pro + positive neutron =neutral and electron= negative
The choices can be found elsewhere and as follows:
<span>A 10 timesB 2 timesC 4 timesD 8 timesE 16 times
I believe the correct answer from the choices listed above is option E. If you turn up the temperature of an oven from 250 degrees kelvin to 500 degrees, the oven will be radiating 16 times.</span>
