Answer:
formula used K=F/∆l
∆l is the elongation of the spring
- F=10N
- ∆l=20mm===> 0.02m
- K=10N divided 0.02m= 500N/m
It’s either snow or rain if it’s a riddle sort of.
Answer:
Part a)
Part b)
Explanation:
As per momentum conservation we know that there is no external force on this system so initial and final momentum must be same
So we will have
Part b)
By equation of kinetic energy we have
"B" When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.
Answer:
Yes
Explanation:
Given that the battery is the same the PD ( potential difference ) in the circuit will also be the same likewise the flow of charge in the circuit,
Hence the same amount of charge flow is delivered to any circuit.
