Answer:
mass of the fish is 8.11 kg
Explanation:
As we know that the frequency of oscillation of spring block system is given as
here we know that the reading of scale varies from 0 to 155 N from length varies from x = 0 to x = 10 cm
Now we have
so now we have
so mass of the fish is 8.11 kg
Answer:
340 W
Explanation:
Power = change in energy / change in time
P = ΔKE / Δt
P = ½ mv² / Δt
P = ½ (90 kg) (15 m/s)² / (30 s)
P = 337.5 W
Rounded to 2 significant figures, the power is 340 W.
Explanation:
Gravitational potential energy
= mgh
= (2kg)(10N/kg)(5m)
= 100J.
A compound optical microscope or just a optical microscope is a microscope that uses light and has more than one lens.
