Answer:
A ball thrown into the air has the most potential energy when it has reached the highest point above the ground before it begins descending. If we consider the vertical motion only beginning when the ball leaves the thrower’s hand, the ball is exchanging kinetic energy for (gravitational) potential energy. When all of the kinetic energy has been transformed, the ball begins falling, and exchanges it’s potential energy back into kinetic energy. If you ignore air resistance, the ball will land with as much energy as it began with.
Answer:
V(peak voltage) is the highest voltage that the waveform will ever attain and the Vrms(root-mean-square) is the effective voltage of the total waveform representing the AC source.
Answer:
I = 0.44 A
Explanation:
The magnetic force on a conductor is given by the expression
F = I L x B
Where bold letters indicate vectors, I is the current, L is the vector in the direction of the current, and B is the magnetic field
Since the force is maximum, the wire must be perpendicular to the magnetic field, therefore
F = I L B sin 90
I = F / L B
Let's calculate
I = 1.2 / 1.5 1.8
I = 0.44 A
Beats only occur when the frequency of two objects is interfere with one another and when those objects are made to identical amplitudes together.
I think the answer is x axis
