You are watching: Water is pumped from a lower reservoir to a higher reservoir
According come the details presented, the is crucial to take into account the principles related come mass flow, particular potential energy and also the strength that will recognize the total work done in the system.
By meaning we understand that the readjust in mass circulation is provided by
Remember the the Discharge is defined as Q = AV, where A is the Area and V is the speed.
Substituting v the worths we have we recognize that the mass flow is identified by
To calculation the strength we require to achieve the certain potential energy, i m sorry is given by
So the power needed to supply the water into the warehouse tank would certainly be
Finally the mechanical power that is convert to heat energy because of friction impacts is:
Therefore the mechanical power as result of friction impact is 6.77kW

Just how strong is the electric force? suppose you had two tiny boxes, each containing 1.0 g that protons. (a) if one to be placed
Let"s usage Newton"s law of second Motion: F=ma. As soon as no other direct force is exhilaration on the system, the acceleration is as result of the gravity. The modified equation becomes: F = mg. So, yes, you need to take into account the gravitational accelerations in the moon and on Earth. g,moon = 1.622 m/s²g,Earth = 9.81 m/s²The net pressure is the stress and anxiety of the string:F,Earth - F,moon = TensionTension = (1/1000 kg)(9.81 m/s²) - (1/1000 kg)(1.622 m/s²)Tension = 8.188×10⁻³ NTo convert, 1 pound force is same to 4.45 Newtons:Tension = 8.188×10⁻³ N * 1 lbf/4.45 NTension = 1.84×10⁻³ lbf

A 39-kg girl is bouncing on a trampoline. Throughout a details interval after ~ leaving the surface of the trampoline her kinetic ener
The street is 0.86 m.
Mass = 39 kg
Initial kinetic energy,
Final kinetic energy,
We must calculate the occupational done
According to work power theorem
Work done is the product that the force and displacement.
From equation (I) and (II)
Hence, The distance is 0.86 m.

A 10 kilogram of mass iron on earth exerts a downward force of 98 newtons. ~ above the moon this exact same 10 kilograms of iron i weighed
Well, the Earth and also the moon have different gravity; a law pressure which defines the attraction an object. For this reason this 10kg mass iron would certainly take longer to fall, together the gravity for planet is 9.8 newton.to discover the force:multiply the mass through the force10x9.8 = 98The gravitation pressure on moon is 1.6310x1.63=16.3this is possible due to the different levels that the grvitaion force on moon and also earth. Us conclude the the attraction that this object is more powerful on planet than on the moon.

A string along which waves can travel is 4.29 m long and has a mass of 228 g. The tension in the cable is 31.1 N. What must be
Length that the string,L = 4.29 m
Mass of the string,m = 228 g
Tension that the string,T = 31.1 N
frequency of travelling, f = ?
Amplitude the the wave,A = 6.83 mm
Average Power,P = 47.1 W.

inserting all the values
f = 199.46 Hz
Hence, the frequency of wave is same to 200 Hz.
