The x and y components of the velocity vector is 17.32 m/s and 10 m/s respectively.
<h3>
What is the x - component of the velocity?</h3>
The x-component of the ball's velocity is the velocity of the ball in the horizontal direction or x-axis.
The velocity of the ball in x-direction is calculated as follows;
Vx = V cosθ
where;
- Vx is the horizontal velocity of the ball
- V is the speed of the ball
- θ is the angle of inclination of the speed
Vx = (20 m/s) x (cos 30)
Vx = 17.32 m/s
The velocity of the ball in y-direction is calculated as follows;
Vy = V sinθ
where;
- Vy is the vertical velocity of the ball
- V is the speed of the ball
- θ is the angle of inclination of the speed
Vy = 20 m/s x sin(30)
Vy = 10 m/s

During the operation of fan we know that it is working on the electricity
So here when we connect the fan with electricity it uses the electrical energy and convert that energy into mechanical energy of fan
Fan uses this electrical energy to rotate the blades of fan and then it gives the high speed air to us
So here correct answer must be
B.
motion energy
Answer:
acceleration m/s²
Explanation:
The units on the left side of the equation are units of length. The units on the right side of the equation must be units of length also. Acceleration times time squared gives length.
Answer:
That depends a bit on what we are charging. Some examples follow...
Explanation:
If the device being charged is just an ordinary insulator (like a balloon rubbed in your hair), what happens is that electrons from you hair transfer onto the balloon, but only act the point of contact. (This is what it means for a substance to be an insulator - charge applied remains at the location it was placed, without moving.)
If we are talking about charging a capacitor, charge from a battery accumulates on the negative plate of the capacitor and by induction, electrons are repelled from the opposite plate, resulting in a positive charge on that plate.
If it is recharging of a battery, the electrons that are supplied to the cathode of the battery cause a chemical process to occur (called reduction) on the surface of the electrode. This reverses the reaction that occurred during the discharge of the battery, and the battery is then ready to deliver current once again.
