Answer:
The value of the power is
Explanation:
From the question we are told that
The power rating
The frequency is
The frequency at which the sound intensity decreases
The decrease in intensity is by

Answer:
The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°
Explanation:
The direction of the force acting on a conductor through which a charge flows is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field
Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force
Looks like a double covalent bond.
O is an element (Oxygen) and H2O2 is a compound (Hydrogen Peroxide)
Answer:before throwing and after catching the ball
Explanation:
When basketball is in the hand of player net force on it zero as holding force is canceled by gravity Force. During its entire motion gravitational force is acting on the ball which is acting downward. Even at highest point gravity is constantly acting downwards.
After catching the ball net force on it zero as holding force is canceled by gravity force and ball is continue to be in stationary motion.
