Answer:
Explanation:
Given that,
Initial speed, u = 5.1 m/s
Final speed, v = 6.2 m/s
Time, t = 25 s
We need to find acceleration. We know that,
acceleration = rate of change of velocity
So, her acceleration is .
When a pendulum swings, potential energy is transformed into kinetic energy, and then back again to potential energy as the speed and elevation of the pendulum vary during the motion
Answer:
Duration
Explanation:
Because duration is not a factor, but it's the outcome or effect or observation from the reaction used to give the rate of reaction
A current carrying wire placed perpendicular to a magnetic field experiences a force equal to
where
I is the current in the wire
L is the wire length
B is the intensity of the magnetic field
In our problem, the length of the wire is L=1.0 m, the magnetic field strength is B=0.20 T and the force exerted on the wire is F=0.60 N. If we re-arrange the equation and we plug these numbers into it, we find the current in the wire:
