Why do we say that a spring is elastic? Why do we say that a spring is elastic? It does not obey Hooke's law. When deformed, it

returns to its original shape. It is made of rubber. When deformed, it does not return to its original shape.

Answer:

When deformed, it returns to its original shape

Explanation:

  • A spring is elastic.  
  • Elasticity is the property of a material to regain its shape after having been deformed.
  • It means that when the force is doubled, the amount of deformation in it gets doubled.
  • Hence, the correct option is (b) " When deformed, it returns to its original shape".

What is Newton's Law of Conservation of Momentum?
Anastaziya [24]

Answer: The law of conservation of linear momentum helps to understand the behavior of a Newton's cradle In a closed system. This law is nothing more than action and reaction.it can be used to predict the resulting direction and speed of motion of objects after they collide.

Explanation: Just as an example, when you play pool/8ball, the white play exerts force on the other balls causing them to break away.

hope this helps.

A girl takes her dog for a walk on a sunny beach. Find the force of gravity between the 45-kg girl and her 11-kg dog when they a
Lady_Fox [76]

The gravitational force acting between them is 8.25*10^-^9N

Data given;

  • M1 = 45kg
  • M2 = 11kg
  • r = 2.0m
  • G = 6.67*10^-^1^1m^3kg^-^1s^-^1

To solve this question, we need to apply gravitational force or energy formula.

<h3>Gravitational Force</h3>

This states that the force of attraction between two bodies is equal to the product of their bodies and inversely proportional to the square of their distance apart.

Mathematically;

F = \frac{GM_1M_2}{r^2} \\

let's substitute the values and solve

F = \frac{Gm_1m_2}{r^2}\\F = \frac{6.67*10^-^1^1 * 45 * 11}{2^2}\\F = 8.25*10^-^9N

The force of gravity acting between them is 8.25*10^-^9N

A steady beam of alpha particles (q = + 2e, mass m = 6.68 × 10-27 kg) traveling with constant kinetic energy 22 MeV carries a cu
cluponka [151]

Answer:

Explanation:

q = 2e = 3.2 x 10^-19 C

mass, m = 6.68 x 10^-27 kg

Kinetic energy, K = 22 MeV

Current, i = 0.27 micro Ampere = 0.27 x 10^-6 A

(a) time, t = 2.8 s

Let N be the alpha particles strike the surface.

N x 2e = q

N x 3.2 x 10^-19 = i t

N x 3.2 x 10^-19 = 0.27 x 10^-6 x 2.8

N = 2.36 x 10^12

(b) Length, L = 16 cm = 0.16 m

Let N be the alpha particles

K = 0.5 x mv²

22 x 1.6 x 10^-13 = 0.5 x 6.68 x 10^-27 x v²

v² = 1.054 x 10^15

v = 3.25 x 10^7 m/s

So, N x 2e = i x t

N x 2e = i x L / v

N x 3.2 x 10^-19 = 2.7 x 10^-7 x 0.16 / (3.25 x 10^7)

N = 4153.85

(c) Us ethe conservation of energy

Kinetic energy = Potential energy

K = q x V

22 x 1.6 x 10^-13 = 2 x 1.5 x 10^-19 x V

V = 1.17 x 10^7 V
