Answer:
a. 250kg I think it's the right answer. hope it helps:)
Answer:
Pressure, 
Explanation:
It is given that,
Combined mass of the man and the chair, m = 95 kg
Radius of the leg of chair, r = 0.5 cm = 0.005 m
A large man sits on a four-legged chair with his feet off the floor. The force acting per unit area is called the pressure exerted.
Area of 4 legs, A = 4 A
So, the pressure each leg exert on the floor is 
. Hence, this is the required solution.
False
It is impossible to get infinite energy let alone to put it inside one battery
Answer:
Thermal energy.
Explanation:
We know that energy is conserved and it only transform one form to another form ,Like potential energy transform in to kinetic energy when a ball fall down from a height and obtain some velocity.
In this case energy changes from gravitational energy to kinetic energy then elastic energy and after some time this energy will convert in to thermal energy.
So the answer is thermal energy.
Answer:
A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.
Explanation:
A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.
Some of the names of the basic quantities include:
- Mass, denoted by the symbol 'm', with S.I. unit 'kg'
- Length, denoted by symbol 'l', with S.I. unit 'm'
- Time, denoted by symbol 't', with S.I. unit 's'
- Current, denoted by 'I', with S.I. unit 's' 'A'
- Temperature, denoted by 'T', with S.I. unit 'K'
- Amount of substance, denoted by 'n', with S.I. unit 'mol'
- Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'
- A basic quantity is chosen arbitrarily.
