Answer:
Negative sign shows that velocity of the car is decreases at a constant rate
Explanation:
We have given velocity of the car is decreases from 32 m /sec to 24 m/sec in 4 second
So initial velocity of the car u = 32 m /sec
And finally car reaches to a velocity of 24 m/sec
Time taken to change in velocity = 4 sec
So final velocity v = 24 m/sec
From first equation of motion v = u+at
So
Negative sign shows that velocity of the car is decreases at a constant rate
Answer:
it means an expert verified the answer so its nearly always true
Explanation:
24hours is the correct answer
Aw, I hate physics, is this on Apex?
Resistance can be calculated with the information given in the question.
Equation for Resistance: R = V/I
V (voltage) = 200 Volts
I (current) = 200 Amps
So 200 divided by 200 = freaking 1
Answer: R = 1 (ohms)
Hope this Helps!
