distance d = 5 km = 5 x 1000 m = 5000 m
time taken = 25 minute = 25 x 60 sec = 1500 sec
average velocity V = d/t
V = 5000/1500
V = 3.33 m/s towards east
Answer:
kinetic energy
Explanation:
Kinetic energy is energy in motion
Answer:
The energy of the electron in a helium ion is 
Explanation:
Given that,
Charge = +1
Value of n = 4
Suppose 
We need to calculate the energy of the electron in a helium ion
Using formula of energy
Put the value into the formula
Hence, The energy of the electron in a helium ion is
Answer:
Savage is the answer
Explanation: The savage people guess like me
Answer:
A.a space station orbiting Earth
Explanation:
As we know that kinetic energy given as
K.E.=1/2 m v²
Where m= mass
v= velocity
If the velocity of the object is zero then it posses zero kinetic energy.
We also know that when object at a height from the ground or from a reference line then it posses potential energy and it does not have kinetic energy because object is in rest position.
In the option B and C system is in rest position that is why these type of system posses zero kinetic energy.
So the answer is A.
A.a space station orbiting Earth
