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,
We can REARRANGE the formula to:
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 kilometresSo, 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» ★ 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. |

Explain how lamps are used to estimate current flowing in a circuit. |
|
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. ............... |

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
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 |
