Answer:

Interchanging the poles of the magnet

Reversing the direction of the applied current

Explanation:

The working of the electric motor is associated with Fleming's left-hand rule.
It states that if a current-carrying conductor is placed inside a magnetic field, it experiences a force in the direction perpendicular to the direction of the electric current and magnetic field.
These three physical quantities are placed in a mutually perpendicular direction.
So, in order to reverse the direction of force, you have to either change the direction of the current or magnetic field.

A uniform rod of length L rests on a frictionless horizontal surface. The rod pivots about a fixed frictionless axis at one end.

Svet_ta [14]

Answer: a) 0.315 (V/L)

Explanation:

From Conservation of angular momentum, we know that

L1 = L2 ,

Therefore MV L/2 = ( Irod + Ib) x W

M/4 x V x L/2 = (M (L/2)^2 + 1/3xMxL^2) x W

M/8 X VL = (ML^2/16 + ML^2 /3 )

After elimination we have,

V/8 = 19/48 x L x W

W = 48/8 x V/19L = 6/19 x V/L

Therefore W = (0.136)X V/L

D.) 5kg

This is a trick question. The mass of an object does not change based in location. However the weight of an object does change, this is because Weight = Mass × Gravity. Also mass is measured in kilograms and so the answer is 5 kg. So if you ever want to lose weight just go to the moon!

Find the total displacement of a mouse that travels 1.0 m north and then 0.8 m south.

andreev551 [17]

North: 1m
South: 0,8m

Direction:

1m>0,8m

so mouse moved north

Distance:

1m-0,8m=0,2m

so mouse traveled 0,2m

Answer: The mouse moved 0,2m north.

A system consists of electrons and protons only. It contains 150 electrons and has a total charge of +22e. What is the mass of t

siniylev [52]

Answer:

Mass of system will be $288.605\times 10^{-28}kg$

Explanation:

We have given a system consist 150 electrons

Mass of one electron $m_{e}=9.1\times 10^{-31}kg$

So mass of 150 electron $=150\times 9.1\times 10^{-31}=1365\times 10^{-31}=1.365\times 10^{-28}kg$

Charge on system is +22e

So number of proton = 150 +22 = 172

Mass of one proton $=1.67\times 10^{-27}kg$

So mass of 172 proton $=172\times 1.67\times 10^{-27}=287.24\times 10^{-27}=287.24\times 10^{-28}kg$

So total mass on the system $=287.24\times 10^{-28}+1.365\times 10^{-28}=288.605\times 10^{-28}kg$
