Question

if F=100N and V=2.5m/s , then power will be how much ?

Answer 1

Answer:

Power is defined as the line rate of doing work or the time rate at which energy is transferred.

• Force (F) = 100 N
• Velocity (v) = 2.5 m/s
• Power (P) = ?

According to the Question now:

$\longrightarrow\rm Power = Force \times velocity$

$\longrightarrow\rm Power = 100 \times 2.5$

$\longrightarrow \red{\rm Power = 250 \:Watt}$

• Dimension of Power (P) is [M¹L²T-³].
• S.I unit of power is Watt or JS-¹.
• CGS unit of power is Erg/s
• Practical units = kilowatt, megawatt and horsepower

Answer 2

Answer:

250 watt
