For an ideal case the temperature should be zero.
Kinetic energy = (1/2) (mass) (speed)²
Since the 'speed' in the KE formula is squared, if the car's speed
increases by 5 times, its kinetic energy increases by (5²) = 25 times.
The loss of kinetic energy in a skid is just the wo0rk done by friction
between the tires and pavement. So the skid distance is proportional
to the initial kinetic energy, and the car must skid 25 times as far when
it enters the skid at the higher speed.
25 x 30m = 750 meters
Answer:
Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
An educated guess to something you should test over and over
Answer:
the car accelerates in
Explanation:
here's the solution : -
we know,
=》
=》
=》
=》
so, acceleration = 1500 m/s^2
now,
=》
here, a = acceleration, v = final velocity,
u = initial velocity, t = time taken.
So,
=》
=》
=》
=》
