For an object thrown vertically upward, its time of flight is equal to the equation below:
t = 2v/g
where
t is the time of flight
v is the initial velocity
g is the acceleration due to gravity equal to 9.81 m/s²
Substituting the values,
7.07 = 2v/9.81
v = 34.68 m/s
Answer:
If you are traveling with a relativity constant velocity, then you will interpret your reference frame as being at rest. Since you are moving faster than the other train, the other train is moving backwards relative to you. Seeing the other train go past your window from front to rear makes it look like the train is going backwards
Explanation:
Answer: Option (c) is the correct answer
Explanation:
It is known that when a neutral object comes in contact with a charged object then an opposite charge develops on the neutral object. But this development of charge occurs only when both the objects come in contact and if they are not in contact with each other then there occurs no charge on the neutral object.
As in the given situation, negatively-charged glass rod is brought near, but does not touch the sphere. So, there will occur no charge on the sphere.
Thus, we can conclude that final charge on the sphere is neutral.
Power is energy per unit time. Therefore, D is the correct one
Answer:
Acceleration
Explanation:
Momentum is acceleration because acceleration is movement and momentum is movement.
Momentun = Movement
Acceleration = Movement
Momentum = Acceleration
