Answer:
4. hours to travel 350km going at a rate of 80km/hr.
Explanation:
Well first you must divide 350/80=4.375~4.
Answer:
The speed of the light signal as viewed from the observer is c.
Explanation:
Recall the basic postulate of the theory of relativity that the speed of light is the same in ALL inertial frames. Based on this, the speed of light is independent of the motion of the observer.
No it would not exceed the 65 mph speed limit.
100 km/hr = 62.13 mph
65 > 62.13
Answer:
9375 N
Explanation:
From the question,
Centripetal force (F) = mv²/r.................. Equation 1
Where m = mass of the car, v = velocity of the car, r = radius of the curve.
Given: m = 900 kg, r = 600 m, v = 25 m/s
Substitute these values into equation 1
F = (900×25²)/600
F = 9375 N.
Hence the centripetal force on the car is 9375 N
That's the symbol for a resistor.
