Answer:
The amp is the basic unit of electrical current.
(A) is correct option.
Explanation:
Current :
The current is equal to the voltage divide by the resistance.
In mathematically,
Where, I = electric current
V = voltage
R = resistance
We need to calculate the unit of current
Put the unit of voltage and resistance
Here,
Hence, The amp is the basic unit of electrical current.

Answer:
Explanation:
Given
W amount of work is done on the system such that it acquires v velocity after operation(initial velocity)
According to work energy theorem work done by all the forces is equal to change in kinetic energy of object
where m=mass of object
v=velocity of object
When the object is already have velocity v then the final speed is given by work energy theorem
From 1 and 2 we get

b) derived
Explanation:
Density is a characteristic property of substances and materials and is defined as the relationship between the mass
and volume
of a specific substance or material, as shown below:
This means density is inversely proportional to volume.
In addition, density is a derived unit, because is based on two basic units of the International Sistem of Units: Mass (kilograms) and Volume (cubic meters)
