The question is incomplete. Here is the complete question.
An inductor, battery, resistance and ammeter and switch are connected in series. If the switch, initially open, is now closed, what is the current's final value?
a. zero
b. Battery voltage divided by inductance
c. battery voltage times inductance
d. battery voltage divided by resistance
Answer: d. battery voltage divided by resistance
Explanation: Resistance, voltage and current are related by <u>Ohm's</u> <u>Law,</u> which is explained as the current that passes through a conductor is directly proportional to the applied voltage. The constant of proportionality between them is <u>Resistance.</u>
Ohm's Law is represented by
<u>Inductor</u> is a component that stores magnetic energy when electricity is applied to it.
<u>Ammeter</u> is an object constructed to measure electric current of a circuit and it is always connected in serie.
So, in the circuit, when the switch is closed, the "only way" for current to pass through is because of Ohm's Law, which means its magnitude will be:
Then, the correct alternative is d. voltage divided by resistance.

Answer:
The coefficient of friction is 0.38.
Explanation:
The free body diagram is drawn below.
Let be frictional force acting in the backward direction as shown. Let the coefficient of friction be
. Let
be the normal reaction force acting on the bag.
Given:
Mass of the bag is,
Force acting at ° is
Acceleration due to gravity is,
The force F can be resolved into its components as and
Therefore,
Now, as there is no acceleration in vertical direction, therefore,
Sum of upward forces = Sum of downward forces
Now, as the bag is moving at a constant speed, so acceleration in the horizontal direction is also zero as acceleration is the rate of change of velocity.
Therefore, backward force = forward force.
Now, frictional force is given as:
Therefore, the coefficient of friction is 0.38.
Answer:
Gravity.
Explanation:
The force that controls the movement of the planets around the sun, holds together stars grouped in galaxies, and galaxies grouped in clusters is called gravity.
This ultimately implies that, gravity is considered to be a universal force of attraction that acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, weight is given by the formula;
Where;
m is the mass of an object.
g is acceleration due to gravity.
Answer:
Explanation:
As we know that height of the slide is given as
so time taken by the child to hit the water from the slide is given as
now we will plug all data in it
now we know that the horizontal distance moved by it is given as
now by energy conservation
so height of point A is given as
