Explanation:

There is a basic DIFFERENCE, because mass is the ACTUAL amount of material contained in a body and is measured in kg, gm, etc. Whereas weight is the force EXERTED by the gravity on that object mg. NOTE that mass is independent of EVERYTHING but weight is different on the earth, moon, etc.

Answer:

W of electron = 5.76 ×10^-23

W of proton = 1.04× 10^-23

Explanation:it will depend on both proton and electron MASS as

W=h/(2ME)^1/2

E=energy in EV

E=1mev= 10^6ev

Now,

Mass of proton = 1.6 ×10^-27kg

Mass of electron = 9.01 × 10^-31kg

W(electron)=

6.65 ×10^-34÷(2×9.01×10^-31×10^6)^1/2

=5.76×10^-23

W(proton)=

6.65×10^-34÷(2×1.6×10^-27×10^6)^1/2

=1.04×10^-23

I hope that this is the answer

If i am wrong then please LET me know.

ANSWER:

plzzz GIVE me brainliest ans and PLZZZZ FOLLOW me

F=frequency (in per second)

W= wavelength(in metre)

E=energy(in joule)

C= velocity of LIGHT(3×10^8m/s)

h=planks constant(6.65×10^-34)

E=hF

F=C/W

E=hC/W

we have to find W

E=1Mev= 1.6×10^-19 ×10^6

E=1.6×10^-13

(1EV= 1.6×10-19 Joule

1M=10^6 Joule)

Now,

hC=6.65×10^-34×3×10^8

hC= 2×10^-25

W=hC/E

W=2×10^-25÷1.6×10^-13

W=20 ×10^-12÷16

W=1.25×10^-12metre

I hope this is the answer if I am wrong then please LET me know

ANSWER:

The MAIN difference between an OHMIC and a non-Ohmic conductor is whether they follow Ohm's law. An Ohmic conductor would have a linear relationship between the current and the voltage. With non-Ohmic CONDUCTORS, the relationship is not linear. A GOOD example of an Ohmic conductor is the resisto

ANSWER:

TURNS to LIQUID and HEAT

Dear Student,

◆ Answer - (1)

Velocity = 8I’ - 6j’ m/s

● Explanation -

# Given -

Speed = 10 m/s

Direction = 4i’ - 3j’

# Solution -

UNIT vector ALONG 4i’ - 3j’ is -

Unit vector = (4i’ - 3j’) / √(4^2 + 3^2)

Unit vector = (4i’-3j’)/5

Velocity of the OBJECT is given by -

Velocity = speed × unit vector

Velocity = 10 × (4i’-3j’)/5

Velocity = 8i’ - 6j’ m/s

Therefore, velocity of object is 8i’-6j’ m/s.

Hope that helps you...

Answer:

The voltmeter is CONNECTED in a parallel connection in an ELECTRIC circuit, because when the current is switched on, the voltmeter SHOWS some resistance. Leading to INCORRECT value of current through the circuit when calculating. Therefore, to avoid the resistance and incorrect reading of current, voltmeter is connected in parallel in a circuit.

ANSWER:

...................

Answer:

Option (3) 6s

Explanation:

Given,

The height of the tower = 100 m

Initial HORIZONTAL speed = 10 m/s

Ball is THROWN horizontally from the top of the tower therefore its initial vertical speed will be zero

Thus using the second equation of motion

The vertical distance h covered in 2 seconds

or, m

Therefore the height left = 100 - 20 = 80 m

The vertical velocity after 2 seconds

using the first equation of motion

m/s

Since the gravity disappears after 2 seconds

therefore there will be no acceleration in the vertical direction

TIME taken to cover 80 m distance = distance/velocity

                                                          = 80/20 = 4 seconds

Therefore, TOTAL time taken by the ball to reach the ground = 2 + 4  =6 seconds

Answer:

360 m

Explanation:

Kinetic ENERGY of bullet = 0.5mv²

= 0.5 × 0.1 kg × (600 m/s)²

= 0.5 × 0.1 × 36 × 10⁴ J

= 1.8 × 10⁴ J

= 18000 J

Potential energy of OBJECT after attaining a HEIGHT "H" = MgH

= 5 kg × 10 m/s² × H

Kinetic energy of bullet is CONVERTED into potential energy of body

18000 J = 5 kg × 10 m/s² × H

H = (18000 J)/(5 kg × 10 m/s²)

= 360 m

Answer:

u

Explanation:

The initial and final SPEED of a projectile is same.

In the GIVEN case:

1. the horizontal component of velocity remains same THROUGHOUT the journey (SINCE there is no acceleration along the horizontal axis)
2. the vertical component of initial velocity reaches zero at maximum HEIGHT and then retains its initial speed when it just touches the ground. It can be proved by "conservation of energy".

Electroplating is the process of coating a metal with a thin layer of ANOTHER metal by electrolysis to IMPROVE the metal's corrosion RESISTANCE.

Answer:

24 m

Explanation:

Time taken to travel first part of the journey (while accelerating) = t

Time taken to travel rest of the journey = 6 - t

Use equation of MOTION: v = U + at

In first part of journey

v = 0 + 2t

v = 2t .....(1)

In second part of journey

0 = v - 4(6 - t)

v = 4(6 - t) .....(2)

Divide equations (1) and (2)

v/v = 2t / (4(6 - t))

1 = t / (2(6 - t))

2(6 - t) = t

12 - 2t = t

3t = 12

t = 4 s

Then, from equation (1)

v = 2t

= 2 × 4

= 8 m/s

DISTANCE covered in first part

x = ut + 0.5at²

= (0 × 4) + (0.5 × 2 × 4²)

= 16 m

Distance covered in second part

y = vt + 0.5a't²

= (8 × 2) + (0.5 × -4 × 2²)

= 16 - 8

= 8 m

Total distance = 16 m + 8 m = 24 m

Answer:

11556600 kg

Explanation:

Volume of water in the tank

= Length × Width × DEPTH

= 51 m × 20 m × 11 m

= 11220 m³

Mass of water = Volume of water × Density of water

= 11220 m³ × 1030 kg/m³

= 11556600 kg

= 11556.6 tonnes

ANSWER:

Plasma is the fourth STATE of matter...

HOPE it HELPS you!

LET time taken by body is t second

distance cover by body = 2T

distance cover after UNIFORM time = 4t

average velocity =( 2t + 4t)/2t = 3m/s

since body follow uniform acceleration so time become same .
