how do you find the kinetic energy of an object?
Answer:
KE = 1/2 * m * [tex]v^{2}[/tex]
Explanation:
use the formula:
KE = 1/2 * m * [tex]v^{2}[/tex]
KE = kinetic energy in joules (J)
m = mass in kg
v = velocity in m/s
Answer:
KE=1/2mv^2
Explanation:
I hope this helps it's just the formula.
KE=1/2×mass×velocity^2
explain electrostatic force
Answer:
Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, or electron, was thus the source of the word 'electricity'.

A man stands in front of a vertical plane mirror which is fixed on a
wall as shown in the diagram below. The image formed by the
mirror is also shown.
The man looks at the image of his feet.
a. Complete the ray diagram to show how the man is able to see the
image of his feet in the mirror.
b. What is the purpose of the normal line in the diagram?
c. State which angle does x represent.
d. What's the type and direction of the image formed by the mirror?
Answer:
a) ray horizontal and ray leaves his feet
b) The normal line respect to which the angles are measured,
c) The angle x is the reflected angle
d) virtual image, right image
Explanation:
a) To complete the rays, you must draw a horizontal ray at the height of the man's head, this ray touches the mirror perpendicularly, therefore it bounces in the same direction.
The other ray leaves his feet and touches the mirror at one point, it is reflected with the same angle, by the law of reflection and reaches the eyes of man, the brain creates an extension of this ray and at the point of the floor creates the image point.
b) The normal line is a line perpendicular to the surface with respect to which the angles are measured,
c) The angle x is the reflected angle, which is equal to the incident angle according to the law of reflection
d) The image is formed by the prolongation of the rays of light, therefore it is a virtual image and as it has the same direction of the man it is a right image

Three components in a parallel circuit have individual resistances of r1, r2, and r3. What formula can you use to determine the total resistance of the circuit?
A. R=r1+r2+r3
B. R=1r1+1r2+1r3
C. 1R=r1+r2+r3
D. 1R=1r1+1r2+1r3
Answer:
D. 1R=1r1+1r2+1r3
Explanation:
If three components are arranged to form a parallel circuit, and the individual resistance of these components are r1, r2, and r3 respectively, the formula for finding the total resistance R is: 1R=1r1+1r2+1r3.
Define A Gamma Ray .....---_---__☘️
Answer:
gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.

3-4 sentences
Answer:
The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe.
Explanation:
Answer:
Hey mate....
Explanation:
This is ur answer.....
According the NASA's StarChild Website, "The universe is a vast open space which contains all of the matter and energy in existence. The universe contains all of the galaxies, nebulae, stars, and planets. The exact size of the universe is unknown. Scientists believe the universe is still expanding outward.

How do you increase the potential energy between two south magnetic
poles?
Answer:
A south pole of one magnet can approach the north pole of another. The magnetic fields are aligned. This makes an attractive force between the two magnets. The farther apart they are, the higher their potential energy.
You want to create a space station that is 50 meters in radius. If you want it to simulate Earth's gravitation, how fast must it go?
Answer:
w = 0.196 rad / s
Explanation:
To generate an acceleration similar to that of the earth, the station's centripetal acceleration must be equal to the acceleration due to gravity.
a_c = v² / r = w² r
a_c = g
we substitute
g = w² r
w² = g / r
w = [tex]\sqrt { \frac{g}{r} }[/tex]
let's calculate
w = √9.8/50
w = 0.196 rad / s
therefore the station must rotate at that angular velocity so that the acceleration in the outer wall is equal to the ratio of gravity

1. Why do you think it is important for people to know when the tides will be high and/or low?
Many reasons. Here are a couple:
1.) Water depth for the draft of incoming ships/vessels so they do not run aground.
2.) Distance between sea level and bottom of structures such as bridges for vessels passing underneath.
A sports car starts at rest at the starting marker then picks up speed, then passes the finish marker in 4.1 seconds. The markers are separated by 120 meters. What is the car's speed at the second marker?
Answer:
S=29.298m/s
Explanation:
Use S=d/t
So, S=120m/4.1s= 29.298m/s
Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of treated glass, aluminum, stainless steel, and copper. The specific heats of these substances are:
Treated glass = 0.75 J/g • °C
