The SI system of amplitude is a metre (m).
Answer:
Explanation:
The work W required for the transfer is equal to the energy difference
where q is the charge we want to transfer and ΔV is the potential difference.
So, the work needed will be
Now, the average power is:
As the Watt is Joule/second, we need the 45 min multiplied by 60:
Taking all this together:
or
22.5 J
Explanation:
Given:
x = 3 m
The spring potential energy is
Answer:
The total kinetic energy of both particles is
Explanation:
Given that,
Kinetic energy of nucleus
Kinetic energy of proton
Radius of proton
We need to calculate the final potential energy
Using formula of final potential energy
Put the value into the formula
We need to calculate the initial energy of both the particles
Using formula of energy
We need to calculate the total kinetic energy of both particles
Using conservation of energy
Hence, The total kinetic energy of both particles is
Answer:
C
Explanation:
Constellations are stellar patterns which are made out of bright stars which appears close to each other and can form a recognisable pattern.
But that does not mean these stars are actually close to each other. The sky that we see from Earth appears as a 2D representation of a 3D Space. If you look in a particular direction in sky you will see all the stars in that direction irrespective of their actual distance from the Earth and hence these stars can be practically very far from each other too.
