Explanation:

Newton's LAW of universal gravitation is usually stated as that every PARTICLE attracts every other particle in the UNIVERSE with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

ong>Answer:

The RESISTANCE of a conductor depends on the cross sectional AREA of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is.

b) BOSE EINSTEIN (answer)

ggggjfhggjfugugjfjhhh

potential difference , V = 198v

Resistance , R = 49.5 OHM

Current , I = V/I

= 198/49.5 = 4 A

TIME , t = 0.25 s

CHARGE , Q = It = 4×0.25 = 1 C

1 C = 6.25 × 10¹⁸ e

Given:-

→ CURRENT flowing = 4 mA

→ TIME = 20 s

To find:-

→ Charge flowing through the conductor.

Solution:-

Firstly let's convert the unit of current from mA to A.

⇒ 1 mA = 0.001 A

⇒ 4 mA = 4(0.001)

⇒ 0.004 A

________________________________

Now, we KNOW that :-

i = Q/t

Where :-

• i is the current flowing.

• Q is the charge.

• t is time.

Substituting values, we get :-

⇒ 0.004 = Q/20

⇒ Q = 20(0.004)

⇒ Q = 0.08 C

Thus, the charge flowing is 0.08 C .

A point mass starts MOVING in straight LINE with CONSTANT acceleration a from REST at t=0. At time t=2s, the acceleration changes the sign remaining the same in magnitude. The mass returns to the initial position at time t=t0 after start of motion.

rong>Answer:

Angular velocity is not constant when a skater pulls in her arms, when a child starts up a merry-go-round from rest, or when a computer’s hard disk slows to a halt when switched off. In all these CASES, there is an angular acceleration, in which ω changes. The FASTER the change occurs, the greater the angular acceleration. Angular acceleration α is defined as the rate of change of angular velocity. In equation form, angular acceleration is expressed as FOLLOWS:

α=ΔωΔt" role="presentation" style="font-family: proxima-nova, sans-serif; -webkit-font-smoothing: subpixel-antialiased; padding: 1px 0px; margin: 0px; font-size: 17.44px; vertical-align: baseline; background: transparent; BORDER: 0px; outline: 0px; display: table-cell !important; line-height: 0; text-indent: 0px; text-align: center; text-transform: none; font-style: normal; font-weight: normal; letter-spacing: normal; overflow-wrap: normal; word-spacing: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 3.384em; min-height: 0px; width: 10000em; position: relative;">α=ΔωΔtα=ΔωΔt,

where Δω is the change in angular velocity and Δt is the change in time. The units of angular acceleration are (rad/s)/s, or rad/s2. If ω increases, then α is positive. If ω decreases, then α is negative.

Solve for the centripetal acceleration of an object moving on a circular path.

Use the EQUATIONS of circular motion to FIND the POSITION, velocity, and acceleration of a particle executing circular motion.

Explain the differences between centripetal acceleration and tangential acceleration resulting from nonuniform circular motion.

Evaluate centripetal and tangential acceleration in nonuniform circular motion, and find the total acceleration vector.

er :- Consider electron e is revolving around nucleus with speed v.

Period of revolution= velocity circumference

T= v 2πr ---- 1

Circulating current I= TTe ----- 2

= 2πr/vv

= 2πrev ---- 3

DEFINITION :-

Magnitude of magnetic moment associated with the circular current is: MM =IA= 2πrev ×πr2---- 4

= 2evr ------- 5

Multiplying and dividing the right-hand side of equation (5) by the mass of

electron, me

then, M0

Definition :-

vr= angular MOMENTUM of the electron revolving around the nucleus.

The ratio of magnetic dipole moment with angular momentum of

revolving electron is called the gyromagnetic ratio.

Gyrometric ratio = L0M0

tional FORCE or (force of friction)

A ball rolling ALONG the GROUND gradually slows down and finally comes to rest. We find no. of visible force appears to be acting on the ball, yes it's SPEED gradually decreases and finally comes to rest after some time. What causes in a change in the STATE of the motion of the ball ? Is there any force acting on the ball to slow it down that gradually Stops it ? In which direction must this force be acting ? This is a force of friction. The force of Friction acting between the surface of the ball and ground that opposes the motion of the ball, brings the moving ball to rest. The force acting along the two surfaces in the contact which opposes the motion of one Object over other is called the force of friction.

Frictional force always opposes the motion of the moving object.

This force of Friction is due to the the roughness of the surfacces of the objects in contact. The more is the roughness of the object, the more the force of Friction between them.

CONDENSER is used to CONDENSE substances from GASEOUS to liquid state, typically by cooling it. In this problem, a stream of humid AIR (31.6 mole% N2, 8.4 mole% O2 and water) enters a condenser in which 90% of the water vapor in the humid air is condensed and removed as liquid water. It is determined that the flow rate of this liquid water leaving the condenser as 500 cm3/hr. Given the properties for the substances as following: Water (SG 1.00 and MW 18.016), N2 (SG 0.967 and MW 28.02) and O2 (SG 1.105 and MW 32.00).
