If the car is accelerating uniformly then,
velocity of car at the fourth second is 16m/s
Then if the car with this velocity stopped after 2s then acceleration is,
a=0-16/2=-8m/s^2
braking distance is given by
d=16*2-0.5*8*2*2
=32-16
=16m
this answer is valid only if the motion is one dimensional
all the best.
Answer:
You're going 3.2 meters per second.
Explanation:
Answer:
Complete Circuit
Explanation:
A circuit is defined as a completed path for voltage to flow from a source of voltage through a load and back to the source. A complete circuit or path is often referred to as a(n) ? circuit. Before current can flow in a circuit, the circuit must be closed. 100% right
The correct option is;
The voltages become negative instead of positive and keep the same magnitudes
Explanation: Here we have that there is a change in direction from positive to negative with the direction pointing to opposite of the initial direction whereby the field strength does not change due to the reversal of the. Therefore the voltage becomes negative instead of negative while keeping the the magnitude.
That is there is a electric field reversal or a change electric field direction.
