A mass is stretched 4 centimeters from the equilibrium position of a spring. The restoring force will also double if the displacement doubles.
The restorative force is a force that acts to return a body to its equilibrium position. The restoring force is always directed back toward the system's equilibrium position and is solely determined by the position of the mass or particle. The restoring force is frequently mentioned in basic harmonic motion.
F = k Hooke's law force or spring force are other names for x. In this equation, x represents the displacement from equilibrium or deformation, F represents the restoring force, and k represents a constant relating to how difficult it is to deform the system. The minus sign represents a restoring force acting in the opposite direction of the displacement.
Thus, The restoring force will also double if the displacement doubles.

Answer:
Water is non-polar molecule False
Water is polar molecule because the electronegativity of Oxygen is much greater than electronegativity of hydrogen and it has also a bend shape that is why it is polar molecule.
Explanation:
I hope this will help you :)
False. Water is a polar molecule.
Water (H2O) consists of two hydrogen atoms and one oxygen atom. The oxygen atom has a higher electronegativity, meaning it attracts electrons more strongly than hydrogen.
As a result, the shared electrons in the covalent bonds between hydrogen and oxygen are pulled closer to the oxygen atom, creating an uneven distribution of charge.
This leads to a partial negative charge (δ-) on the oxygen atom and partial positive charges (δ+) on the hydrogen atoms, making water a polar molecule.

The answer is B
If we assign speed variable x; and time variable y; then;
xy=150
(y-1) (x+5) = 150
xy + 5y - x – 5 = 150
(remember xy = 150), therefore;
5y – x = 5
X = 25
Y = 6
Answer:
The torque about the origin is 5.0 N.
Explanation:
To calculate the torque (τ) about the origin, you need to know both the force (F) and the position vector (r) from the origin to the point where the force is applied. The formula for torque is:
τ = r × F
Where:
- τ is the torque vector.
- r is the position vector.
- F is the force vector.
In this case, you're given the force vector F = 5.0 y N, where "y" represents the unit vector in the y-direction.
Assuming that the particle is located at a position where the position vector r is given as (x, y), you need to express the position vector in terms of unit vectors. Since the force is applied along the y-axis, you can write the position vector as:
r = x i + y j
Now, you can calculate the torque:
τ = r × F
τ = (x i + y j) × (5.0 y N)
When you take the cross product, the component of the position vector along the direction of the force will contribute to the torque. In this case, only the y-component of the position vector (y j) is along the direction of the force (5.0 y N).
So, the torque about the origin is:
τ = y (5.0 y N)
Now, you can calculate the magnitude of the torque:
|τ| = |y (5.0 y N)| = 5.0 |y|^2 N
The magnitude of the unit vector "y" is 1, so:
|τ| = 5.0 N
The torque about the origin is 5.0 N.
Answer: If one billiard ball hits another, the second will move with the same force as the first.
A child wants to jump to climb a tree (reaction), he must push the ground to propel himself (action).
A man deflates a balloon; the force with which the air comes out causes the balloon to move from one side to the other.
Explanation:
-Hitting A Wall
-Rowing a boat
-Walking
Explanation:
1.If you hit a Wall with your hands or legs, you get hurt. Why?
Because of Newton's Third Law. You hit the wall with a force and that exact same amount of force is returned by the wall.
2. While Rowing a boat, when you want to move forward on a boat, you paddle by pushing the water backwards, causing you to move forward.
3.While Walking, You push the floor or the surface you are walking on with your toes, And the surface pushes your legs up, helping you to lift your legs up.
b. white objects
c. black objects
d. purple object
The food chain will collapse with the decreases and increases of other organisms caused by the removed organism.
