What is static electricity and how does it differ from current electricity
sp2606 [1]

Answer:

1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. 2. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity.

The moment of inertia of a thin ring of mass M and radius R about its symmetry axis is ICM = MR2.
monitta

Answer:

The moment of inertia of large ring is 2MR².

(A) is correct option.

Explanation:

Given that,

Mass of ring = M

Radius of ring = R

Moment of inertia of a thin ring = MR²

Moment of inertia :

Moment of inertia is the product of the mass of the ring and square of radius of the ring.

We need to calculate the moment of inertia of large ring

Using formula of moment of inertia

I=I_{cm}+MR^2

Where, I_{cm} = moment of inertia at center of mass

M = mass of ring

R = radius of ring

Put the value into the formula

I=MR^2+MR^2

I=2MR^2

Hence, The moment of inertia of large ring is 2MR².

A uniform plank of weight 100 N is 2000 mm long and rests on a support that is 400 mm from end E. At what distance from E must a
yan [13]

Answer:

the location of 160 N from end E is 25mm

Explanation:

given:

A uniform plank of weight 100 N is 2000 mm long

and rests on a support that is 400 mm from end E

find:

At what distance from E must a 160 N weight be placed in order to balance the plank?

                                                                      160 N

                                                                           |---x--->|

                                      100N                           \|/

======================||======================E

                                                            Δ---- 400mm---->|

|<----------------------------  2000mm   --------------------------->|

to determine the location of 160N load in order to balance the plank,

you have to take moment at support Δ.

note:

the 100 N is located at the center of a plank.

the distance of 100N from support = (2000 / 2) - 400 = 600mm

∑moment at Δ = 0

0 = -100 N (600mm) + 160 N (400-x)

0 = -60000 N.mm + 64000 N.mm - 160x N.mm

0 = 4000 - 160x

160x = 4000

x = 4000/160

x = 25 mm

therefore,

the location of 160 N from end E is 25mm
