MariettaO [177]

Answer:

3801.13 N

Explanation:

Pressure exerted on a surface is equivalent to applied force divided by the cross sectional area. Then, the applied force will be equal to the product of the pressure exerted and the cross sectional area.

Where given:

Atmospheric pressure (P1) = 1.013*10^5 Pa

T1 =  20+273.15 = 293.15 K

P2 = ?

T2 = 120+273.15 = 393.15 K

Using the gas equation: P1/T1 = P2/T2

Therefore, P2 = P1*T2/T1 = 1.013*10^5 *393.15/293.15 = 13.6*10^4 Pa

The net pressure = P2 - P1 = 13.6*10^4 - 1.013*10^5 = 34.6 kPa

The net force F_{120} = net pressure * area

Area = 0.11 m^2

Thus:  

The net force F_{120} = 34555.7*0.11 = 3801.13 N

trapecia [35]

Answer:

we can say that with a smaller magnitude , the field will point is in same direction

Explanation:

we have given that

solenoid is filled with a diamagnetic material and with air, magnetic field pointing along its axis in the positive x direction

so in small magnitude, the field will point is in same direction

Does a battery produce electric currents?
Leokris [45]

Answer:

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
