Answer:
It’s 1
Explanation:
Potential difference =Work Done (in Joules)/ Total Charge(in Coulomb)
So Here
Potential difference =2J/2C
=1V
thankyou : )
Answer:
The work done required is
Explanation:
Given that,
Stretch spring = 2 cm
Stretch spring = 1 cm
We need to calculate the work done
Using formula of work done
Put the value into the formula
.....(I)
We need to calculate the work done
Using formula of work done
Put the value into the formula
.....(II)
We need to calculate the work done
Using equation (I) and (II)
Hence, The work done required is
The answer is c it reflects the suns light back to earth
Answer:
15.0 m/s
Explanation:
When elastic collision occurs, the final velocities, v of the bodies are obtained by
Where u and m denote initial velocities and mass while the subscripts 1 and 2 are for tennis ball and the other ball
Substituting 0.311 for mass of tennis, 0.0570 for mass of the other ball, 30.3 m/s for velocity of tennis ball and -19.2 m/s
