A black hole forms as a result of the collapse of the center of a massive star into itself. This process is known as supernova.
The gravitational pull of the black hole is enormously strong enough that nothing can escape it not even any electromagnetic radiations or light and absorbs everything that tries to cross it as a result of enormously massive star into a very tiny or small space.
<span>Angular distance moved = 220 rad = {35(2π) ≈ 220 rad} Max angular speed = 18 rad/s Final angular speed = 0 rad/s Avg angular speed = 9 rad/s {assuming a CONSTANT de-celeration of wheel} Time to stop = 220/9 = 24.4 s ANS</span>
Let the total distance from the ground be “h” , so the distance travelled in last one second will be “ h/2”. So as it is free fall , u(initial velocity) = 0.
When a person is making cardiovascular gains through aerobic activity they are increasing the amount of oxygen to the heart and lungs. This keeps the heart and lungs of a person very healthy. It decreases the chance of heart diseases.
