Answer:
a = -10m/s²
Explanation:
Givens:
Vf = 0m/s
Vi = 50m/s
t = 5s
Use the following kinematic equation:
Vf = Vi+at
Rearrange
a = (Vf-Vi)/t
a = -10m/s²

Explanation:
Because you need 5 N to push a 5 kg object so 5 will be left over
Name two ways to decrease the electric force between two charged objects.
Answer:
Inverse relationships are common in nature. In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.
Explanation:
Two ways to decrease the electric force between two charged objects:
by lessen charge of the test objects.by increasing distance between test change and source charge.What is coulomb force?As a result of their electric charge, particles or objects are attracted to or repelled by the Coulomb force, also known as electrostatic force or Coulomb interaction. Charles-Augustin de Coulomb, a French scientist who published the findings of an experimental inquiry into the proper quantitative description of this force in 1785, gave the electric force its name. The electric force is one of the fundamental physical forces.
Positive or negative electric charges that are similar to one another repel one another in a straight line between their centers. Positive and negative charges that are opposite each other are drawn together along a straight line connecting their centers.

Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating charge that has charge q and acceleration a is given by dEdt=q2a26πϵ0c3 where c is the speed of light.Part AIf a proton with a kinetic energy of 5.0 MeV is traveling in a particle accelerator in a circular orbit with a radius of 0.530 m , what fraction of its energy does it radiate per second?(dE/dt)⋅1sE =
Answer:
P /K = 1,997 10⁻³⁶ s⁻¹
Explanation:
For this exercise let's start by finding the radiation emitted from the accelerator
[tex]\frac{dE}{dt}[/tex] = [tex]\frac{q^{2} a^{2} }{6\pi \epsilon_{o} c^{2} }[/tex]
the radius of the orbit is the radius of the accelerator a = r = 0.530 m
let's calculate
\frac{dE}{dt} = [(1.6 10⁻¹⁹)² 0.530²] / [6π 8.85 10⁻¹² (3 108)³]
P= \frac{dE}{dt}= 1.597 10⁻⁵⁴ W
Now let's reduce the kinetic energy to SI units
K = 5.0 10⁶ eV (1.6 10⁻¹⁹ J / 1 eV) = 8.0 10⁻¹⁹ J
the fraction of energy emitted is
P / K = 1.597 10⁻⁵⁴ / 8.0 10⁻¹⁹
P /K = 1,997 10⁻³⁶ s⁻¹

Leo places a plant in front of the center of curvature of a concave mirror. Which characteristics will the image of the plant have? Check all that apply.
Answer:
1, 3, 5,
Explanation:
A concave mirror is a hollowed sphere that has been cut into parts, each of which has a painted exterior. The plant's image has the qualities of a real, inverted, and smaller image. So, the correct options are A, C and E.
What is Concave mirror?A hollow spherical formed into a mirror when the external surface of the each cut portion was painted, reflecting light from the interior surface. This kind of mirror is known as a concave mirror. When the concave mirror is placed too close to the item, a magnified and phoney image results.
This has an inward-curving reflective surface that faces away from the source of light. Light is reflected internally to a single focus point. Headlights on cars and torches are examples of concave mirrors. But, as the distance grows between the object and the mirror, the size of the image reduces and a real image is produced.
Thus, the correct options are A, C and E.

Real virtual inverted upright smaller larger same size.Biker 1 is on a motorcycle facing West is initially at rest. The motorcycle speeds up from rest to 25 mph in three seconds.
Biker 2 is right by his side to start. He speeds up from rest to 85 mph in eight seconds.
Which biker has a greater acceleration?
Biker 1's acceleration:
(25 mph) / (3 s) = ((25 mi/h) • (1/3600 h/s)) / (3 s) ≈ 0.00231 mi/s²
Biker 2's acceleration:
(85 mph) / (8 s) = ((85 mi/h) • (1/3600 h/s)) / (8 s) ≈ 0.00295 mi/s²
Biker 2 has the greater acceleration.
A rock has a mass of 3.1 kg. What is its weight on earth
Answer:
W = 30.38 N
Explanation:
Given that,
Mass of a rock, m = 3.1 kg
We need to find the weight of the rock on the surface of Earth. Weight of an object is given by :
W = mg
g is the acceleration due to gravity, g = 9.8 m/s²
W = 3.1 kg × 9.8 m/s²
= 30.38 N
So, the weight of the rock on the Earth is 30.38 N.

is lighting firecrackers a form of conduction, convention, or radiation
Answer:
Convection
Explanation:
conduction is like, electricity. radiation is like using a microwave.
Answer:
conduction
Explanation:
recall that conduction is the transfer of heat between objects that come in direcr contact.
You are putting heat directly on the part of the firework that allows it to spark, therefore it is conduction.
Convection takes place within a fluid.
Radiation is indirect heat through waves. (think of the sun warming us indirectly)
Professional research telescopes should be large enough to gather sufficient radiation from space. Which of these statements best explains why a reflecting telescope is best used as a professional research telescope?
Question 5 options:
Mirrors of reflecting telescopes gather harmful radiations from space.
Bigger lenses are easier to manufacture and they produce less distortion.
The series of mirrors and lenses help to reduce distortion of images.
Reflecting telescopes reflect away more radiation and distort images.
Answer:
Bigger lenses are easier to manufacture and they produce less distortion.
Explanation:
A reflecting telescope is best used as a professional research telescope because " Bigger lenses are easier to manufacture and they produce less distortion."
This is evident in the fact that the mirror of a reflecting telescope is simpler and inexpensive to be manufactured.
Also reflecting telescope is known not to support chromatic distortion, which often is a byproduct of dispersion.

Karla Ayala pulls a sled on an icy road (dangerous!). Because of Karla's pull, the tension force is 151 N, and the rope makes a 20.0° with the horizontal. If the 7.0-kg sled is pulled across 10.0 meters, what is the work done by Karla?
Answer:
W = 1418.9 J = 1.418 KJ
Explanation:
In order to find the work done by the pull force applied by Karla, we need to can use the formula of work done. This formula tells us that work done on a body is the product of the distance covered by the object with the component of force applied in the direction of that displacement:
W = F.d
W = Fd Cosθ
where,
W = Work Done = ?
F = Force = 151 N
d = distance covered = 10 m
θ = Angle with horizontal = 20°
Therefore,
W = (151 N)(10 m) Cos 20°
W = 1418.9 J = 1.418 KJ

PLS HELP which ones would be made of cells? and which ones show cell walls?
Cork, Sponge, Wood, Plastic, Tree
The first question's answer depends on what you mean by "sponge". If you're talking about sea sponges, then all but plastic are made up of cells. Some sponges used for cleaning are also made of plant material but also other, non-organic materials like dyes.
Cell walls are only present in plant cells, so they would be found in cork (derived from a certain tree bark), wood, and trees. Synthetic sponges made with plant material might also contain them, but they wouldn't be made entirely of cells with walls.
From given options or choices all are made up of cells except plastic and among the other four Cork, Sponge, Wood, and tree all show cell walls except Sponge.
A cell is the basic structural unit of all living organisms and contains various cell organelles. On the base of different cell organelles or presence or absence of the certain organelles help in distinct and divide the cell type.
The major types of cells are:
Prokaryotic cellsEukaryotic cellsPlastic is not a living organism as there are no cells and is made up of polymers of hydrocarbon.
The cell wall is one of the major cellular structures that helps in identifying the type of cell organism and protects the organism from the external environment. It classifies the organism on its constituent of the cell wall.
In eukaryotic cells, animal cells have no cell wall, however, fungi cells, plant cells have a cell wall. A sponge is an animal and other cork wood, and trees are plants or plant-based products.
Thus, the sponge does not show the cell wall.
