No, it is impossible to determine the exact location of an electron. This is because electrons don't have a definite position, and direction of motion, at the same time and its movements are unpredictable
The gravitational force of attraction between two objects is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.
Where,
G = Gravitational Universal Constant
M = Mass of the Planet
m = Mass of the object
r = Distance
Therefore the amount of force exerted by the first object on the second object is equal to the amount of the force exerted on the second object by the first.
The gravitational force exerted by Larry on the Earth is same as the force exerted on Larry by the Earth.
That is 300N.
Answer:
remote control, neon and fluorescent lights, wireless transmission, computers, smartphones
Explanation:
The weight is the force of gravity acting on the object. So assuming it’s on earth, 12(9.81) also, F(weight in Newtons)=mass( in kg)acceleration (due to gravity)
Answer:
When walking towards the back of a bus while it moves forward its apparent velocity seems slower than it actually is with respect to the ground.
Explanation:
- When a someone follows a moving bus from behind by walking then the apparent speed of the bus is slightly slower by the same magnitude as the speed of walking because both are moving in the same direction.
- This is the concept of relative velocity when the apparent velocity of the same object appears different to different viewers at the same time being on different frame of motion.
- When the same bus is observed from a point on the road the speed of the bus will appear greater than the former case discussed above because the bus here is moving with respect to a stationary observer.
