Oh okay the first person who answered is incorrect but
0—> PE=0J
1—>PE=1J
20—>PE=20J
50—>PE=50J
100—>PE=100J
Answer:
It is a copy of an object and appears to be coming from behind the mirror.
Explanation:
- The plane mirror has a flat surface, where of its surface is polished to reflect the light.
- The plane mirror shows the image as the same size of the object.
- The image produced by the plane mirror is virtual and erect.
- But the orientation of the image formed changes the left and right.
- Hence,the image appears to be coming from behind the mirror.
Answer:
91.5 km
Explanation:
Hi!
If we are to ignore the variation in gravity we can use the formula for teh potential energy near the surface of a planet:
mgh
If the energy of the material ejected from the volcano on Io's surface is the same on earth's surface we have:

where subindexes Io and e means Jupiter's moon Io, and Earth, respectively
solving for h_e

The acceleration due to the gravity of a planet can be calculated as:

Where R and m are the radius and mass of the planet
Therefore:

m_e = 5,972 × 10^24 kg
R_e = 6 371 km
Replacing all given values:
h_e = 500 km *(0.183) = 91.515 990 km
The statement 'energy cannot be created or destroyed' BEST supports the idea that energy remains constant during an energy transformation. It is the first law of thermodynamics.
<h3>Law of Conservation of Energy</h3>
The law of conservation of energy, also known as the first law of thermodynamics, indicates that energy can neither be created nor destroyed.
According to this law, the energy can be interchanged from one type of energy (e.g., kinetic energy) form to another (e.g., potential energy).
The first law of thermodynamics is fundamental for understanding major science disciplines, and it is a rosetta stone in physics.

Answer:
The maximum electrical force is
.
Explanation:
Given that,
Speed of cyclotron = 1200 km/s
Initially the two protons are having kinetic energy given by

When they come to the closest distance the total kinetic energy is converts into potential energy given by
Using conservation of energy


Put the value into the formula


We need to calculate the maximum electrical force
Using formula of force



Hence, The maximum electrical force is
.
