Non-renewable energy comes from SOURCES that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes. Most non-renewable energy sources are FOSSIL fuels: coal, petroleum, and natural GAS. CARBON is the main element in fossil fuels.

Answer:

6000 A

Explanation:

1.0003 WAVELENGTH of YELLOW LIGHT in vacuum=6000 A

ANSWER:

ANSWER :

• The recoil velocity of gun is -0.5 m/s

Given :

• Mass of bullet = 100 g = 0.1 kg

• Mass of gun = 20 kg

• Velocity = 100 m/s

To Find :

• Recoil velocity of the gun = ?

Concept Used :

To CALCULATE the recoil velocity of gun we need to know the concept of conservation of momentum!!

• Conservation of Momentum = Mass × Velocity

Solution :

Hence we conclude that,

Momentum(before gun was supposed to be fired) = Momentum of gun + Momentum of bullet

Let us assume the recoil velocity of gun as v m/s !!

By applying law of conservation of momentum,

★ Conservation of Momentum = Mass × Velocity

➝ 20 + 0.1 kg × 0= 20 × v + 0.1 ×100

➝ 0 = 20v+ 10

➝ 0 - 10 = 20v

➝ v = -10/20

➝ v = -0.5 m/s

The velocity of recoil is -0.5 m/s.

Here, the minus sign INDICATES that the gun recoils in the opposite direction to the direction that of the bullet!!

⠀⠀━━━━━━━━━━━━

More to know :

• Recoil velocity is the backward velocity .

• It is experienced by a SHOOTER when he shoots a bullet.

• Hence, it is the RESULT of conservation of momentum .

Answer:

TWO plane monochromatic waves propagating in the same direction with amplitudes

and DIFFERING UN PHASE by

superimpose. Calculate the amplitude of the resulting wave.

Answer:

Mass of two blocks which are connected to massless string:

>>> 20 kg and 10 kg

DISTANCE travel by the 20 kg block:

>>> 0.6 m

Acceleration due to gravity:

>>> 10 m/s²

INITIAL velocity:

>>> 0

Time TAKEN to travel

First find the acceleration of the both block with the massless string:

Where,

a = Acceleration

m1 = Mass of the FIRST block

m2 = Mass of the second block

And then use the second equation of MOTION to find the time taken:

Where,

s = Distance travelled

ut = Initial velocity

a = Acceleration

t = Time taken

To find the acceleration subtract mass of 1 st block with the acceleration due to gravity like this :

Where,

a = Acceleration

m1 = Mass of the first block

m2 = Mass of the second block

g = Acceleration due to gravity

First , acceleration:

___________________________________

Now , find the time taken:

So , the time taken by the first block is 0.6 seconds .

First equation of motion:

Where,

Vf = Final velocity

Vi = Initial velocity

a = Acceleration

t = Time

Third equation of motion:

Where,

v² = Final velocity

u² = Initial velocity

a = Acceleration

t = Time

Fourth equation of motion:

Where,

v² = Final velocity

u² = Initial velocity

a = Acceleration

Answer:Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these THREE quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, ASSUMING you know the composition of the material.

Calculations are straightforward for solid objects, but things get more COMPLICATED for liquids, where density changes with TEMPERATURE, and for gases, for which density is dependent on temperature and pressure.

Use Consistent Units

The equation relating density, mass and volume is straightforward and allows you to calculate the density of a material if you measure its mass and volume. The only caveat is that you have to make the measurements in the same system.

TO FIND:

• Gavitational force between the two bodies.

EXPLANATION:

Here G is the universal gravitational constant.

Hence the force between the two bodies =
