Answer:
This is the complete answer and step by step explanation.
Given:
a = 3m/s
m = 85 kg
Unknown:
The Kinetic energy of the man jogging
Formula and solution:
KE = 1/2 mv²
KE = 1/2(85 kg)(3 m/s)²
KE = (42.5 kg)(9 m²/s²)
Final Answer:
KE = 382.5 kg.m²/s² or simplify as 382.5 J is the kinetic energy of man jogging
As we know that gravitational force of Sun will provide the centripetal force to all planets
so here we will have


here we know that



now from above equation




Answer:
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Yes, but it's a null vector .So,no vector can have a component at right angle to itself unless it is a zero vector.
<span>Immediate and long lasting because they pollute the water itself which is the most important commodity for humans. Dirty water gives us all types of diseases which are all long lasting and the body has a immediate reaction to the pollutants in the water. Drinking polluted water or even bathing in it can be very harmful to the human body.</span>
