Power is the energy transferred or "WORK DONE" in one second
nordsb [41]3 years ago
5 0

Answer:

Explanation:

Work done is defined as the product of force in the direction of displacement and the displacement.

Work = force in the direction of displacement x displacement

It is a scalar quantity and its SI uni is Joule.

Power is defined as the rate of doing work.

Power = Work / time

It is also a scalar quantity and its SI unit is Watt.

Assume: The bullet penetrates into the block and stops due to its friction with the block. The compound system of the block plus
charle [14.2K]

Answer:

The total energy of the composite system is 7.8 J.

Explanation:

Given that,

Height = 0.15 m

Radius of circular arc = 0.27 m

Suppose, the entire track is friction less. a bullet with a m₁ = 30 g mass is fired horizontally into a block of wood with m₂ = 5.29 kg mass. the acceleration of gravity is 9.8 m/s.

Calculate the total energy of the composite system at any time after the collision.

We need to calculate the total energy of the composite system

Total energy of the system at any time = Potential energy of the system at the stopping point

E=mgh+Mgh

E=(m+M)gh

Put the value in to the formula

E=(30\times10^{-3}+5.29)\times 9.8\times0.15

E=7.8\ J

Hence, The total energy of the composite system is 7.8 J.

the headlamp of a car takes a current of 0.4 ampere from a 12 volt supply. the energy produced in 5 minutes is​
serg [7]
Voltage (V) = 12 v
Current (I) = 0.4 A
Time (t) = 5min = 300sec

Power = Voltage x Current
= V x I
= 12 x 0.4
Power = 4.8wats = 4.8W

Power = Energy / Time
Energy = Power x Time
Energy = 4.8 x 300
Energy = 1440 joules
Final answer : 1440J

A 2kg object is moving horizontally with a speed of 4m/s 2. How much net force is required t keep the object moving at this spee
dezoksy [38]
To continue moving at constant speed in a straight line requires NO net force. Zero. Nada. If there IS any net force on the object, then its speed or direction will change.
