Answer:

Down the plane

Explanation:

  • Consider an electron moving left to right in horizontal direction enters a region of a constant magnetic field B which points in the upward direction is acted upon by a force having direction into the plane of the screen which is in accordance to the Fleming's left hand rule.
  • When the left palm extends thumb, middle finger and the index finger mutually perpendicular to each other then the index finger represents the direction of magnetic field. Middle finger represents the direction of motion of a positive charge (assume reverse if the charge is negative) and the thumb represents the direction of force acting on the charge.

What role did gravity played in the formation of the solar system​
hodyreva [135]

Gravity is the cause of . . .

-- star formation,

-- planet formation,

-- orbits.

So without gravity, there pretty much wouldn't be any solar or any system.

I was reading an old thermodynamics textbook and came across this equation describing change in internal energy. What does the (
RoseWind [281]

Explanation:

I remember that notation! The expression

dQ = dU = (\dfrac{\partial U}{\partial T})_{V} dT+ (\dfrac{\partial U}{\partial V})_{T}dV

is the 1st law of thermodynamics and it refers to the heat supplied to the system dQ which is also a change in its internal energy dU. The first term is the <u>partial</u> derivative of the internal energy U with respect to temperature T while the volume V is kept constant, as denoted by the subscript V. The 2nd term is similar but this time, temperature is kept constant while its volume partial derivative is being taken.

Ah, memories!

How is thermal energy naturally transferred between objects?
Sladkaya [172]

The second law of thermodynamics establishes restrictions on the flow of thermal energy between two bodies. This law states that the energy does not flow spontaneously from a low temperature object T1, to another object that is at a high temperature T2.

For example. Suppose you place your cell phone on the table. Your phone is at a temperature of 40 ° C and the table is at 19 ° C. Then, it is impossible for the table to spontaneously transfer its thermal energy to the telephone, and so that the table gets colder and the telephone warmer.


Finally we can say that the correct option is B: From the hotter object to the cooler object

A 2kg Book is sitting on a table.a 10n Force is pulling to the right.a 3n Force is pulling to the left what is the net force act
salantis [7]


The net force = sum of all forces acting on the body



If we take left side as -ve and right side as +ve,
then,

The net force here would be equal to,
10N + (- 3N)
= 7N.


Therefore, a net force of +7N ( + indicates it's moving towards right) is acting on the book of mass 2kg.
