In this sense, I believe that we simply divide both currents.
Therefore, we do 16 / 2 = ... 8. And to check answer, we turn back to equation. 8 = voltage (x) (2) equals 16.
Answer:
Answer:
Sound is produced when an object vibrates, creating a pressure wave.
Explanation:
This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. ... The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
(a) time taken for the car to accelerate from v to 2v = t =
(b) velocity of the car moving at 2t seconds = ΔV = 2at
(a) we know that,
a=
where, is the final velocity
is the initial velocity
a = acceleration
t = time
Time taken to accelerate from V to 2V:
t =
(b) We know that,
a=
where, is the final velocity
is the initial velocity
a = acceleration
t = time
how fast is the car moving at 2t seconds after starting,
we can represent - = ΔV
at time = t= 2t, it becomes
a= = a = ΔV/2t
t= ΔV/2a
ΔV = 2at
<h3>What is acceleration?</h3>
Rate of change of velocity with time, both in terms of speed and direction is known as acceleration.
<h3>What is speed?</h3>
- the rate at which an object's location changes in any direction.
- The distance traveled in relation to the time it took to travel that distance is how speed is defined.
- Since speed simply has a direction and no magnitude, it is a scalar quantity.

Answer:
Explanation:
opposite charges attract
same charges repel
neutral charges don't attract or repel
Charge = (current) x (time)
Charge = (0.4 Ampere) x (2 seconds)
Charge = (0.4 Coulomb/second) x (2 seconds)
<em>Charge = 0.8 Coulombs</em>
