A free positive charge released in an electric field will _____

Physics
1 answer:
morpeh [17]3 years ago
4 0

Answer:

Accelerates in the same direction as the field

Explanation:

When a charge is immersed in an electric field, the charge experiences an electric force, whose magnitude is given by

F = qE

where q is the magnitude of the charge and E is the magnitude of the electric field.

The direction of the force depends on the sign of the charge. In particular,

- For a positive charge, F and E have the same direction

- For a negative charge, F and E have opposite directions

Therefore, a free positive charge will experience a force in the same direction as the field - therefore, it will accelerate in the same direction.

Suppose a large truck on a hydraulic lift exerts 7,000 N of force on a piston with an area of 0.4 m2. The piston can only suppor
uysha [10]

Pressure is the amount of force per unit area. In formula it is,

P = F ÷ A

P = 7000 N ÷ 0.4 m2

P = 17,500 N/m2

The amount of pressure the truck exerts on the piston is 17,500 N/m2

A frictionless piston–cylinder device contains 7 kg of nitrogen at 100 kPa and 250 K. Nitrogen is now compressed slowly accordin
lora16 [44]

Answer: -1038.8 kJ

Explanation:

From the question, we can see that PV^n = constant. And as such, we can deduce that it is a polytropic process. Thus, we can use the polytropic work equation to calculate the needed work input.

from the question we were given

Mass of nitrogen, m = 7kg

initial temperature, T1 = 250k

Final temperature, T2 = 450k

Polytropic index, n = 1.4

Specific gas constant, R = 0.2968kJ/kgK

W = [p2 * v2 - p1 * v1] / 1 - n

W = [m * R * T2 - T1] / 1 - n

W = 7*0.2968*(450 - 250)] / 1 - 1.4

W = [7*0.2968*200] / -0.4

W = 415.52 / -0.4

W = -1038.8 kJ
