The angle subtended by moon at a point on earth is 31'. If the distance of moon from earth is 3.34 x 10^8 m, find the diameter of the moon.​

Answer»

Answer:

The diameter will be approximately 3000 km.

Explanation:

The formula for angular size is:

δ = 2 arc SIN(d/2D)

Here,

  • δ  is the angular size
  • d is the diameter of the object (in this case the Moon
  • D is the distance.

We can REARRANGE the formula to:

  • d = 2D sin(δ/2)
  • δ = 31′ ≈ 0.5167
  • D = 3.34×10⁸ m  

If we plug in the values:

⇒ d ≈ 2 ×3.34 × 10⁸ × sin(0.5167/2)

⇒ d ≈ 6.68 × 10⁸ × sin(0.2583)  

⇒ d ≈ 6.68 × 10⁸ × 0.0045

⇒ d ≈ 3011846 m

⇒ d ≈ 3011.846 km

⇒ d ≈ 3000 kilometres

So, the diameter will be approximately 3000 km.

Two cubes of side 20 cm each, having20 kg and 10 kg of mass. find the density of cubes. Are they madematerial? Justify your answer.​

Answer»

\large\color{red} \mathrm{Hey \: There!}

Edge of each cube = 20cm

=> VOLUME of each cube = (20)^3 = 800cm^3

Mass of CUBE1 = 20kg

Mass of CUBE2 = 10kg.

Thus,

Density of Cube1 :-

m = 20 kg

V = 800cm^3

=> Density (d1) = m/V

d1 = 20/800

d1 = 1/40

=> d1 = 0.025 kg/cm^3

Density of Cube2 :-

m = 10 kg

V = 800cm^3

=> Density (d2) = m/V

d2 = 10/800

d2= 1/80

=> d2 = 0.0125 kg/cm^3

Here, d1 ≠ d2, therefore, we can CONCLUDE that both cubes are made from different materials.

If 0.2ohm, 0.3ohm, 0.4ohm, 0.5ohm and 12ohm resistors are connected to a 9v battery in parallel, what will be the current through the 12ohm resistor? ​

Answer»

GIVEN ,

  • The 0.2 ohm , 0.3 ohm , 0.4 ohm , 0.5 ohm and 12 ohm resistors are CONNECTED to a 9 v battery in parallel

We know that ,

The current flowing through the conductor is directly proportional to the potential difference of the battery

\sf \mapsto V  \propto I \\  \\\sf \mapsto V = IR

The constant of PROPORTIONALITY R is called resistance of the conductor

Thus , the current flowing through the 12 ohm resistor will be

9 = I × 12

I = 9/12

I = 0.75 amp

Answer»

Answer:

Answer: It is measured in the unit of the Ampere, SIMPLY called “Amp,” (A). The most COMMON way to measure current in a circuit is to BREAK the circuit open and insert an “ammeter” in series (in-line) with the circuit so that all electrons flowing through the circuit also have to GO through the meter. ...............

A force of 5 N given a mass m an acceleration of 10 m s a mass m an acceleration of 20 m s what acceleration would if given if both the masses were tied together​

Answer»

Explanation:

Using Newton's second law,

F = m a

5 = M1 × 10

M1 = 5/10 = 0.5 kg

And

5 = M2 × 20

M2 = 5/20 = 0.25 kg

Total MASS = 0.5 + 0.25 = 0.75 kg

Now as per QUESTION,

Let common acceleration is a,

F = (M1 +M2) ×a

5 = 0.75 × a

a = 5/0.75 =500/75 = 6.67 m/s²

1. The speed-time graph of a particle moving along a fixed direction is shown in figure. Find:Distance travelled by the particle between 0 sec to 10 secAverage speed between this intervalThe time when the speed was minimum(iv)The time when speed was maximum.Speed (ms)​

Answer»

Explanation:

Distance travelled by the particle = Area under the given graph

= (1/2) × (10 – 0) × (12 – 0) = 60 m

Average SPEED = Distance / Time = 60 / 10 = 6 m/s

(b) Let s1 and s2 be the distances covered by the particle between time

t = 2 s to 5 s and t = 5 s to 6 s respectively.

Total distance (s) covered by the particle in time t = 2 s to 6 s

s = s1 + s2 … (i)

For distance s1:

Let u′ be the velocity of the particle after 2 s and a′ be the acceleration of the particle in t = 0 to t = 5 s.

Since the particle undergoes uniform acceleration in the interval t = 0 to t = 5 s, from first equation of motion, acceleration can be obtained as:

v = u + at

Where,

v = Final velocity of the particle

12 = 0 + a′ × 5

a′ = 12 / 5 = 2.4 ms-2

Again, from first equation of motion, we have

v = u + at

= 0 + 2.4 × 2 = 4.8 m/s

Distance travelled by the particle between time 2 s and 5 s i.e., in 3 s

s1 = u‘ t + (1/2)a‘ T2

= 4.8 × 3 + (1/2) × 2.4 × (3)2

= 25.2 m ……..(ii)

For distance s2:

Let a″ be the acceleration of the particle between time t = 5 s and t = 10 s.

From first equation of motion,

v = u + at (where v = 0 as the particle finally comes to rest)

0 = 12 + a″ × 5

a″ = -12 / 5 = – 2.4 ms-2

Distance travelled by the particle in 1s (i.e., between t = 5 s and t = 6 s)

s2 = u“ t + (1/2)a″ t2

= 12 × 1 + (1/2) (-2.4) × (1)2

= 12 – 1.2 = 10.8 m ………(iii)

From equations (i), (ii), and (iii), we get

s = 25.2 + 10.8 = 36 m

∴ Average speed = 36 / 4 = 9 m

A Block of weight 50N pushed By a force Fon a horizontal plane moves with acceleration 2m/s when force is doubled its acceleration becomes 6m/s the coefficient of friction is(g=10m/s)​

Answer»

Explanation:

GIVEN that,

Weight, W=100N

Acceleration, a=1m/s

2

Acceleration when FORCE is double, a=10m/s

2

Now, Let the External Force be F and friction force be f.

Then,

F−f

s

=ma

F−μN=ma

F−μ100=10×1

F−μ100=10....(I)

We know, When Force is doubled,

Then,

2F−f

s

=ma

2F−μN=ma

2F−μ100=10×10

2F−μ100=100....(II)

Now, from equation (I) and (II)

F=90N

Now, put the VALUE of F in equation (I)

90−μ100=10

−μ100=10−90

μ=

100

80

μ=0.8

Hence, the coefficient of RESTITUTION is 0.8

x coordinate and y coordinate of a particle is x=(2t^3)/3m, y= (t^2+t)m find the accleration of the particle at t=1 sec

Answer»

Answer:

⃗a(1) = 4i + 2j

| ⃗a(1)| = √20 m/s²

EXPLANATION:

Given

The X co- ordinate of the particle is

x =  \frac{2}{3}  {t}^{3}  \: m

The y co-ordinate of the particle is GIVEN by

y  = ( {t}^{2}  + t) \: m

Calculation

To CALCULATE acceleration we have to calculate d²y/dt² and d²x/dt².

\frac{dy}{dt}  = \frac{d}{dt} (t²+t)  =  2t + 1

\frac{d²y}{dt²}  = \frac{d}{dt} (2t+1)  =  2

\frac{dx}{dt}  = \frac{2}{3} \frac{d}{dt}(t³)  =  2t²

\frac{d²x}{dt²}  = 2 \frac{d}{dt}(t²)  =  4t

⃗a = \frac{d²x}{dt²}i +  \frac{d²y}{dt²}j

⃗a = 4t i +  2j

⃗a(1) = 4*1 i + 2 j

⃗a(1) = 4i + 2j

| ⃗a(1)| = √(4² + 2²)

| ⃗a(1)| = √20 m/s²

a moving particle reduce its velocity from 10 metre per second square to 5 metre per second square in 5 second find acceleration​

Answer»

Answer:

hope it helps you

Explanation:

A = (V - u)/t

= (0 - u)/t

= -u / (5 s)

S = ut + 0.5at²

100 = 5u + (0.5 × [-u / (5 s)] × (5 s)²)

100 = 5u - 2.5u

100 = 2.5u

u = 40 m/s

If u = 40 m/s then

a = -u / (5 s)

= -(40 m/s) / (5 s)

= -8 m/s²

DISPLACEMENT covered in 10 seconds

S = ut + 0.5at²

= (40 m/s × 10 s) + [0.5 × (-8 m/s² × (10 s)²]

= 0 m

Particle travelled 100 m in first 5 seconds and in next 5 seconds it travels 100 m back to initial position. Hence we got Displacement after 10 seconds equal to zero.
