write the formula and the SI unit of the power,electiric charge andpressure
Answers
Answer:
Explanation:
POWER
In the International System of Units, the unit of power is the watt(W), equal to one joule per second. P = E/t: This formula is also called the mechanical power equation. Here E stands for energy in joule and t stands for time in seconds. This formula states that the consumption of energy per unit of time is called power.
ELECTRIC CHARGE
SI unit = coulomb
formula = Q = I.t
PRESSURE
SI UNIT = The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2). Pascal is a so-called coherent derived unit in the SI with a special name and symbom
Formula = The formula for pressure is P = F/A, in which P is pressure, F is force, and A is area.
Answer:
SI unit if power - Watt (W)
SI unit of electric charge - Coulomb (C)
SI unit of pressure - Pascal (Pa)
Explanation:
Power is defined as the rate of doing a particular amount of work. Its formula is given as:
Power = work done / time
The SI unit of power is Watt (W).
Electric charge is the basic property of the particles of an element how they behave in an electric field. Its formula is given as:
Electric charge = current × time
The SI unit of electric charge is coulomb (C).
Pressure is defined as the force acting per unit area. Its formula is given as:
Pressure = force / area
The SI unit of pressure is Pascal (Pa).
