Answer:
The answer is time
Explanation:
So when youre given force and distance, you can determine work done
Work Done = Force × Distance travelled in the
direction of the force
Since Power = Work Done/ Time
when you know work done, and you want to find power, you will need time.
Because you have work done already, you dont need energy. Though you can use energy and time to find work too. The alternative formula for Power would be:
Power = Energy Converted/Time
Explanation:
thomas edison and Nikola tesla were involved in the war of currents
Answer:
1.33
Explanation:
speed of light in vacuum, c = 3 x 10^8 m/s
speed of light in medium, v = 2.26 x 10^8 m/s
The refractive index of the medium is given by
μ = speed of light in vacuum / speed of light in medium
μ = (3 x 10^8) / (2.26 x 10^8)
μ = 1.33
Answer:
Explanation:
If m is the mass of the object and v is the velocity of the object. The kinetic energy is due to the motion of an object. It is given by the relation as follows :
The above formula is used to find the kinetic energy of an object.
The error percentage in measuring the volume of the cylindrical box is 6.3 x 10⁻³ %
<h3>
Error percentage in measuring the volume of the cylinder</h3>
The total error percentage in measuring the volume of the cylinder is calculated as follows;
Volume of cylinder = πr²h
Volume of cylinder = π(0.03r)²(0.07h)
Volume of cylinder = (6.3 x 10⁻⁵)πr²h
Error in measuring the volume = 6.3 x 10⁻⁵ x 100% = 6.3 x 10⁻³ %
