The relationship between object distance, image distance, and focal length of a spherical mirror is given by
1/f=1/v+1/u
Where
f= focal length of a spherical mirror (distance between the pole and the principal focus of the mirror)
u= object distance (distance between pole and object)
v= image distance (the distance between pole and image)
The correct answer is the following.
The forces that act on the piano are: 2) gravitational force acting on the piano (piano's weight). 5) force of the floor on the piano (normal force). 7) force of Chadwick on the piano.
As we see in the picture that I have attached is Chadwick pushing the piano in a horizontal plane. So Chadwick is applying a force that produces an acceleration. It is his force on the piano plus the acceleration of the weight of the piano, it's a gravitational force. This is pure physics applied to an object.
Answer:
a = 16 m/s²
General Formulas and Concepts:
<u>Dynamics</u>
Newton's Law of Motions
- Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion
- Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration)
- Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction<u>
</u>
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] F = 22000 N
[Given] m = 1375 kg
[Solve] a
<u>Step 2: Find Acceleration</u>
- Substitute in variables [Newton's 2nd Law of Motion]: 22000 N = (1375 kg)a
- Isolate <em>a</em>: 16 m/s² = a
- Rewrite: a = 16 m/s²
Answer:I think it’s self monitoring sorry if wrong
Explanation:
Answer:
To see objects smaller than microscopic limits
Explanation:
The theory of Relativistic Quantum mechanics can be applied to particles that are massive and propagates at all velocities even those which are comparable to the speed of light and is capable to accommodate particles that are mass less. This theory find its application in atomic physics, high energy physics, etc.
It is necessary to use relativistic quantum mechanics when it is desired to see the objects that are too small to be seen with the help of microscope.
