Answer:
Resistors restrict current flow through a circuit.
(The electrons don't easily get from one side to the other)
High voltage is actually needed for to send power over long distances because if you use high current, a lot of the power is lost to the resistance in the wires.
Explanation:
hope it helps <3
It is a conglomeration of rock that collected together over time, and it rotating in a spinning ball that is orbiting a sun that is in the middle of our solar system.
You should look at a picture of the earth from a satellite.<span />
Explanation:
Initially, the object is at rest, u = 0
Acceleration of the object,
(a) Distance travel in 2 second can be calculated using second equation of motion as :
(b) Distance travel in 4 second can be calculated using second equation of motion as :
(c) Initial velocity of the object, u = 4 m/s
(d)
Hence, this is the required solution.
<span>For maximum visibility, backing a vehicle requires a driver to:
Adjust the mirrors so that the driver can see the intended trailer path.
</span>when driver is moving backward or backing a vehicle, adjusting of mirror is important factor because a driver can see backward from the mirror.
Always park back in a space.
<span>There are also other factors a driver should keep in mind:
Turn your head also while backing
back slowly and should ready to stop any moment
if someone is walking behind the vehicle, horn the vehicle etc

Answer:
3947.7 kg/m³
Explanation:
The relativistic density can be calculated using below expression;
ρ = ρ' /[√( 1 - v²/c²)]
where,
ρ = Change in Density as a result of motion
ρ'= Actual density of cube
ρ' is given as = 1800 kg/m³
v = Velocity that the cube moves = 0.89c
c = Speed of light
c= 3×10^8 m/s
ρ = ρ' /[√( 1 - v²/c²)]
if we substitute the given values we have
ρ= 1800/ √ 〈1- 0.89c²/ c²〉
ρ=3947.7 kg/m³
Hence, the cube's density is 3947.7 kg/m³
