Answer:
5 pounds of force in the opposite direction
Explanation:
If a ball is rolling 5 pounds of force, to stop this ball, we would require 5 pounds of force in the opposite direction.
A force is a pull or push on a body. It can be with contact or without any contact.
Therefore, to stop this body direct an equal and opposite amount of force to it.
Based on Newton's third law of motion "action and reaction forces are equal and opposite in their actions"

Why can't you see individual atoms with special tools?
Answer:
Atoms are so much smaller than the wavelength of visible light that the two don't really interact.
Explanation:
To put it another way, atoms are invisible to light itself.
Visible light has a wavelength that ranges from 400 to 700 nm. Atoms, in contrast, typically have a diameter of between 0.1 and 0.3 nm. The size difference is greater than a thousand times, even with straightforward calculations.
What are the properties of atoms?Over 500,000 times of magnification are possible using an electron microscope, which is sufficient to observe a great deal of information inside cells.
The electron microscope comes in a variety of varieties. Atoms and nanoparticles can be observed with the use of a transmission electron microscope.
In a chemical reaction, atoms cannot be formed or destroyed, since they are indivisible units. The mass and chemical characteristics of each atom of a specific element are the same.
Therefore, the atom's structure is invisible to visible light.

49. A vertically hung 0.50-meter- long spring is stretched from its equilibrium position to a length of 1.00 meter by a weight attached to the spring. If 15 joules of elastic potential energy are stored in the spring , what is the value of the spring constant?
Answer:
[tex]K=120[/tex]
Explanation:
From the question we are told that
Length of spring [tex]l_1=0.5m[/tex]
Length of stretched [tex]l_s=1m[/tex]
Potential energy of spring [tex]E=15J[/tex]
Generally equation for energy stored is mathematically given as
[tex]U=1/2K \triangle x^2[/tex]
[tex]K=\frac{2U}{\triangle x^2}[/tex]
[tex]K=\frac{2*15}{ 0.5^2}[/tex]
Therefore value of the spring constant in N/m? is given as
[tex]K=120[/tex]
The value of the spring constant is 120 N/m.
Spring constant
The spring constant of the spring is calculated by applying the principle of conservation of energy as follows;
[tex]\frac{1}{2} k \Delta x = U[/tex]
Where;
K is the spring constantΔx is the extensionU is the elastic energyThe value of the spring constant is calculated as follows;
[tex]k = \frac{2U}{\Delta x} \\\\k = \frac{2\times 15}{0.5^2}\\\\k = 120 \ N/m[/tex]

A freight train has a mass of 270, 700 kg and has an acceleration of 40 m/s2. How much force is acting on the train? Formula:
Answer:
1.08 x 10⁷N
Explanation:
Given parameters:
Mass of freight train = 270700kg
Acceleration = 40m/s²
Unknown:
Force acting on the train = ?
Solution:
From Newton's second law of motion, we know that:
Force = mass x acceleration
So;
Force = 270700 x 40 = 1.08 x 10⁷N

A man is attempting to push a chair across the floor exerting a force of 50 N .When will the chair exert a force of 50 N on the man?
Answer:
ALWAYS ( in all cases and at all times)
Explanation:
From Newton's 3rd Law of motion which states that every action that occurs (force) there will be equal as well as opposite reaction. Therefore as the man is pushing the chair exerting 50N force, the chair also is is exerting equal force as well as opposite force on him as he is pushing it

a truck starts from rest and accelerates for 25 seconds to reach a velocity of 60m/s . calculate the rate of acceleration for the truck
Answer:
2.4m/s²
Explanation:
Given parameters:
Initial velocity = 0m/s
Time 25s
Final velocity = 60m/s
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of displacement
Acceleration = [tex]\frac{Final velocity - Initial velocity}{time}[/tex]
Acceleration = [tex]\frac{60 - 0}{25}[/tex] = 2.4m/s³

Sliding friction is friction that acts on objects when they are sliding over a surface. Sliding friction is weaker than static friction. That's why it's easier to slide a piece of furniture over the floor after you start it moving than it is to get it moving in the first place.

Waves propagate along a stretched string at a speed of 8.0 m/s. The end of the string vibrates up and down once every 1.5 s. What is the wavelength of the waves traveling along the string?
Answer:
So we have waves F= 1/t So F= 1/1.5= 0.66V= wavelength × F 8.0m/s= x × 0.66x=12.2The wavelength of the waves traveling along the string is 12 meters.
What is a Wavelength?
The distance between adjacent successive crests or troughs of a wave is termed as its wavelength. Wavelength is calculated in the wave's direction.Given:
Waves propagate along the stretched string at speed = 8.0 m/s
The end of the string vibrates up and down once every 1.5 s.
∴ Time = 1.5 s
We have to find the wavelength of the waves.
We know,
⇒ Time = 1/frequency
⇒ 1/frequency = 1.5
Now
⇒ speed = frequency × wavelength
⇒ wavelength = speed / frequency
⇒ wavelength = 8 × 1.5
⇒ wavelength = 12 m
Therefore, the wavelength of the waves traveling along the string with given speed is 12 m.

are clocks permanently stuck to walls?
Answer:
It depends
Explanation:
what is this question
Answer:
No...
Explanation:
I think this may be a trick question... so from my reasonable logic, I'm gonna say no because more often then not they are attached to the wall with nails/screws. Or they are hanging.
So they could come off. Also if someone was desperate, they could always grab a chainsaw and force it off of the wall. Not a great idea though, then the wall would be broken!! Most likely the clock too!
