Inertia is defined as the tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force.
When a bus at rest starts to move suddenly,the passenger move backward because of inertia of the passenger to remain in the state of rest .
Answer:
Newton's second law of motion states that the acceleration ( a) experienced by an object is directly proportional to the net force ( Fnet) experienced by the object and inversely proportional to the mass of the object. In equation form, it could be said that a = Fnet/m. The net force is the vector sum of all the individual force values.
Explanation:
The fraction of Oil will be 0.8and block will be 0.95
What is density?
Density is the ratio of Mass of a compound upon Volume of that compound. It's SI unit can be g/cm³, kg/m³.
As we know the Density of water is 997Kg/m³≈1000Kg /m³.
1) Fraction of Oil is
800/1000=0.8
2) Fraction of Block is
950/1000= 0.95.

Answer:
Electric Potential V=130 V
Explanation:
Electrical potential inside a hollow sphere is constant and is equal to electric potential of surface
So
Electric Potential V=130 V
Answer:
The magnetic field at the center of the solenoid is approximately 0.0117 T
Explanation:
Given;
length of the solenoid, L = 15 cm = 0.15 m
number of turns of the solenoid, N = 350 turns
current in the solenoid, I = 4.0 A
The magnetic field at the center of the solenoid is given by;
Therefore, the magnetic field at the center of the solenoid is approximately 0.0117 T.
