A 20N net force acts upon an object with a mass of 4. 0kg. What is the object's acceleration?

Answers

Answer 1

Answer:

5ms^-2

Explanation:

F = 20N, m = 4.0kg, a = ?

Using the formula for Force

F = ma

Then making acceleration the subject of the formula

a = F/m

a = 20N/4.0kg

a = 5ms^-2

1. A box with a mass of 6 kilograms is pushed with a net force of 10N to
the right on a frictionless surface. Calculate the acceleration of the box. *

Answers

Answer:

[tex]a=1.67\ m/s^2[/tex]

Explanation:

Given that,

Mass of the box, m = 6 kg

The net force acting on the box, F = 10 N

We need to find the acceleration of the box. We know that the force acting on an object is given by :

F = ma

a is the acceleration of the box,

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{10\ N}{6\ kg}\\\\a=1.67\ m/s^2[/tex]

So, the acceleration of the box is [tex]1.67\ m/s^2[/tex].

What is the mass of an object with a velocity of 24.1 m/s and a momentum of 28.3 kg m/s?​

Answers

Answer:

1.17427...kg

Explanation:

Assumptions: no friction, no air resistance, no internal resistance, and it is 1 dimensional travel for velocity.

p=mv, where p is momentum, m is mass, and v is velocity

28.3=24.1(m)

divide both sides by 24.1

you get 1.174273859

Answer:

[tex]\boxed {\tt 1.17427386 \ kilograms}[/tex]

Explanation:

The formula for momentum is:

[tex]p=mv[/tex]

From this formula, we know that mass can be found by dividing the momentum by the velocity.

[tex]\frac{p}{v}=m[/tex]

The momentum is 28.3 kg m/s and the velocity is 24.1 m/s

[tex]p=28.3 \ kg \ m/s \\v=24.1 \ m/s[/tex]

[tex]\frac{28.3 \ kg \ m/s }{24.1 \ m/s} =m[/tex]

Divide. The meters per second or "m/s" will cancel each other out.

[tex]\frac{28.3 \ kg}{24.1} =m[/tex]

[tex]1.17427386 \ kg=m[/tex]

The mass of the object is 1.17427386 kilograms.

predict the long term cost and benefit of using renewable or non renewable resources. please help will give brainliest ​

Answers

Answer:

The long term cost and benefit of renewable resources is that it is most likely a one-time purchase kind of thing. For example, if you use solar energy, you only have to buy the solar panels for your roof once. However, if you use gas oil to cook, you have to keep buying since it runs out. Sunlight doesn't run out.

The long term cost and benefit of non renewable resources is that it is something you can profit off of very easily. It will take a lot of time for people to completely switch over to renewable resources, so it is something that can steadily bring in money. Examples of non renewable resources that people constantly use is oil, gas, coal, etc.

Answers

Force is studied by physics and according to it four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

What is force?

It is that magnitude that affects a body and is responsible for changes in its state of motion, according to quantum mechanics ordered from weakest to strongest are:

Gravitational force is the force exerted by one mass on the other, being a weak force.

Weak nuclear force is the force responsible for radioactive decay.

Electromagnetic force is the force that affects electrically charged particles and has two directions (attraction-repulsion).

Strong nuclear force is the force that keeps the nuclei of atoms stable, being stronger than the electromagnetic force.

Therefore, we can conclude that four fundamental forces are recognized at the quantum level ordered from weakest to strongest are: the gravitational force, the weak nuclear force, the electromagnetic force and the strong nuclear force.

Explanation:

Because plants cant move and animals can.

The characteristic which describes an organism of kingdom Animalia is able to move on its own when compared to the plants kingdom. Thus, the correct option is A.

What are the characteristics of Animalia Kingdom?

Animals are the multicellular, eukaryotic organisms in the biological kingdom Animalia. Animals are the organisms which consume organic material, breathe oxygen gas, are able to move on their own, can reproduce sexually and produce organisms which contain genetic information which is recombination of both the parents, and these organisms go through an ontogenetic stage in which their body consists of a hollow sphere of the cells, the blastula, during the embryonic development of organisms.

Organisms belong to Animal kingdom show some characteristics which are not found in the organisms which belong to the plant kingdom including movement. Animals can move on their own while plants cannot.

its final velocity?

Answers

Answer:

Vf = ≈56.436 m/s

Explanation:

We'll need to use the equation:

Vf^2 = Vi^2 + 2aΔx

Plugging in what we know, we get:

Vf^2 = (0)^2 + 2(4.55)(350)

Finally, some algebra:

There is nothing physical about radio waves. They are pulses of energy caused by periodic variations in electric and magnetic fields. These are caused by electrons “jumping” between energy levels. Radio waves have the lowest energy, longest wavelengths and lowest frequencies. These values change gradually as we go through microwaves, infra red, visible light, ultra violet, x-rats abd gamma rays which have the highest energy, highest frequency and shortest wavelength.

Answers

The electric field strength is defined as the ratio of electric force and charge. The electric field strength will be 2.8 ×10⁵ N/C.

What is electric field strength?

The electric field strength is defined as the ratio of electric force and charge. The field's direction is determined by the direction of the force acting on the positive charge.

A positive charge produces a radially outward electric field, whereas a negative charge produces a radially inward electric field.

The given data in the problem is;

Q is the charge= 6. 4 × 10–7 C

E is the electric force=1. 8 × 10–1 N

The relation between the electrostatic force and the electric field due to a charge is given as:

[tex]\rm F_E=Q E \\\\ \rm E=\frac{F_E}{Q} \\\\ \rm E=\frac{1.8\times 10^{-1}}{6.4\times 10^{-7}} \\\\ \rm E=2. 8 \times 10^5\ N/C.[/tex]

Hence the electric field strength will be 2.8 ×10⁵ N/C.
