A scooter acqired a velocityof 36km/h in 10 sec just after the start. Calclate the accleration of the scooter.

Answer»

Hey dear......

Given that,
U = 0
V = 36km/h or 10m/s
T = 10 SEC
A = V - U/T
= 10 - 0/10
= 10/10
= 1m/s

The work done per mole of gas in an isothermal expansion is which relation

Answer»

HEYA DEAR........

system = gas The gas pushes upward and does WORK on the piston: W > 0. For an ideal gas that EXPANDS isothermally, all of the heat that is transferred into the gas (in this case, 269 J) is CONVERTED to work done by the gas on its surroundings.

Two spherical balls of masses 2kg and 4kg move along the same line with velocities 1.5m/s and 2 m/s. They collide and after collision the second ball moves with a velocity 1.5 the m/s. Find the velocity of the first ball.

Answer»

Heya mate......

It is given that

m1= 2kg. m2= 3kg (masses of the bodies)

U1=6m/s and u2=4m/s (where u1 and u2 are INITIAL velocities of the bodies)

v1=? v2=3m/s (where v1 and v2 are final velocities of the bodies)

We KNOW that momentum before collision=

Momentum after collision

And momentum = Mass*Velocity

Therefore, m1*u1+m2*u2=m1*v1+m2*v2

2*6+3*4=2*v1+3*3

12+12=2v1+9

2v1=15

v1=15/2=7.5

On what factors does the capacitance of an parallel plate capacitor depends on?

Answer»

A parallel plate capacitor consists of two large parallel conducting PLATES separated by a SMALL DISTANCE.

Factors on which the CAPACITANCE of a parallel plate capacitor depends :-
1. Area of the plate (Capacitance directly proporational to Area)
2. Distance between the plates (inversely proportional)
3. Permittivity of the medium between the plates (directly proportional)

It is possible that a body covers a certain distance but its displacement is zero

Answer»

Yes, it is possible.
if a BODY moves and returns to its starting position, then its displacement is zero.
displacement is the shortest PATH between the starting point and the ending point. of the starting point and ending point is same, then displacement is zero.
we observe this in CIRCULAR motion.
however, distance cannot be zero of a body moves.

Train covers half of its journey with speed of 30 M per second and other half with a speed of 40 metre per second calculate average speed of train during whole journey

Answer»

Let the distance be 2D.
& let The TIME be t.
Case1:
Distance (1)=d
SPEED (1)=30m/s
:.Time(1)=distance(1)/speed(1)
=D/30
Case2:
Distance (2)=d
Speed(2)=40
:. Time (2)=distance (2)/speed(2)
=D/40
Now,
Average speed=total distance/total time
=(d+d)/{t(1)+t(2)}
=2d/(d/30+d/40)
=2d/(40d+30d)/(30×40)
=2d/70d/1200
=(2d×1200)/70d
=2400d/70d
=2400/70
=34.29m/s

An object moves 20 meter in 3 minutes and 30 meter in 4 minutes, calculate its average speed.

Answer»

AVERAGE SPEED = Total distance ÷ Total time

Since, both the TIMES have been given in minutes so we need to convert them into SECONDS..

So 3min= 180 sec
4min= 240 sec

Therefore,
average speed = 20+30 ÷ 180+240
= 50÷420
=0.1190 m/s
