Explanation:
The linear momentum of a particle is defined as the product of the mass of the particle times the velocity of that particle. Conservation of momentum of a particle is a property exhibited by any particle where the total amount of momentum never changes. Linear momentum of a particle is a vector quantity and is denoted by →p
Answer:
0.25 J
Explanation:
Given that
Force on the spring, F = 30 N
Natural length of the spring, l1 = 20 cm = 0.2 m
Final length of the spring, l2 = 35 cm = 0.35 m
Extension of the spring, x = 0.35 - 0.2 = 0.15 m
The other extension is 40 - 35 cm = 5 cm = 0.05 m
Work done = ?
Considering Hooke's Law of Elasticity.
We're told that the spring stretches through 15 cm, and thereafter asked to find the work done in stretching it through 5 cm
The question is solved in the attachment below
We know, U = F * h
U = 25 * 3
U = 75 J
In short, Your Answer would be 75 Joules
Hope this helps!
Sine value is defined in the following way
Explanation:
- In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. Try this Drag any vertex of the triangle and see how the sine of A and C are calculated. The sine function, along with cosine and tangent, is one of the three most common trigonometric functions.
- Let's start with the basic sine function, f (t) = sin(t). This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of 2π because the sine wave repeats every 2π units.
