A 5 Kg mass has an initial speed of 5m/s. After 3 sec, it has come to a speed of 70 m/s.

a. What is the acceleration of the mass?
b. What net force is acting on the mass during those 3 seconds?

Answers

Answer:

a

 [tex]a = 21.7 \ m/s^2[/tex]

b

[tex]F = 108.5 \ N[/tex]  

Explanation:

From the question we told that

   The mass is  m  =  5 kg

    The initial speed [tex]u = 5 m/s[/tex]

    The time taken to attain [tex]v = 70 \ m/s[/tex] is  t =  3 s

   

Generally from kinematic equation we have that

     [tex]v = u + at[/tex]

=> [tex]70 = 5 + a * 3[/tex]

=>  [tex]a = 21.7 \ m/s^2[/tex]

Generally  the force acting is mathematically represented

        [tex]F = m * a[/tex]

=>      [tex]F = 5 * 21.7[/tex]  

=>      [tex]F = 108.5 \ N[/tex]

Describe a way to separate a mixture of fine sand and table salt without having to directly sort tiny crystals using tweezers.

Answers

Answer:

you can add water to the mixture and dissolve the salt

The method used is by solubility which is dissolving the sand and salt mixture into water and heating.

This is just about methods of separations of mixtures.

There are three major methods that can be used to separate a mixture of sand from salt. They are;

- Physical separation by use of magnifying glass and tweezers.

- Dissolving the mixture in water

- Melting the salt

The first method can't be used because we are told to use another method.

In that case, we will use the second option which involves solubility.

Now, salt is made up of sodium chloride which means it is an ionic compound and it will be soluble in water whereas sand is not soluble in water as it contains mainly silicon dioxide.

Now, the process involved in this separation is as follows;

- Pour the mixture into a container.

- Add water to the mixture in the container.

- Turn on a burner and heat this solution in the container till the salt has dissolved completely.

- Then after that, turn of the burner and allow the heated solution to cool off a bit.

- After it has cooled a bit, pour the salt solution on top into another empty container.

- Then collect the sand out of the heated container.

- Then heat the salt solution until the water dries and only the salt is left.

Answers

-2m/s^2

Explanation:

final velocity = 20m/s

initial velocity = 50 m/s

time taken = 60 s

20-50=30m/s

30/60 = -2

A motorbike reaches a speed of 20 m/s over 60m, whilst
accelerating at 3m/s?, determine the bike's initial speed.

Answers

Initial speed = 2√10 m/s

Further explanation  

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

An equation of uniformly accelerated motion  

V = vo + at  

Vt² = vo² + 2a (x-xo)  

x = distance on t  

vo / vi = initial speed  

vt / vf = speed on t / final speed  

a = acceleration  

vf=20 m/s

d = 60 m

a = 3 m/s²

[tex]\tt vf^2=vi^2+2.ad\\\\20^2=vi^2+2\times 3\times 60\\\\400=vi^2+360\\\\40=vi^2\\\\vi=\sqrt{40}=2\sqrt{10}~m/s[/tex]

The measurement of how much matter an object contains is its
a. volume.
b. weight.
c. mass.
d. melting point.

Answers

Answer:

Mass is how much matter an object contains. Mass and weight are different measurements, although they may seem similar. Mass is measured by comparing one object to another object of known mass. Grams and kilograms are units we use to measure mass.

The measurement of quantity of matter in an object is mass ( optionC)

What is mass of a body?

Mass of a body is defined as the quantity of matter(Solid, liquid or gas) contained in the given volume of the body.

Mass is a scalar quantity and also part of the fundamental quantities. It is measured in kilograms. Other units of mass include; gram tonnes e.t.c

Matter is anything that takes up space and can be weighed.

Therefore the quantity of matter in a body is

called mass.

How does changing the number of neutrons affect an atom?

Answers

Answer:

If you change the number of neutrons in an atom, you get an isotope of the same element. The addition of a neutron can make an atom radioactive. When you change the number of protons in an atom, you will change the atom from one element to a different element.

Explanation:

The characteristics of the atomic nucleus allow to find the answer for the effect of the change of neutrons in an atoms is

The change in neutrons changes the atomic mass.

A chemical element is made up of protons, neutrons and electrons; the first two are in the atomic nucleus and the electrons are in orbits around them.

The number of protons corresponds to the atomic number and its change changes the type of element.

The neutrons that are neutral charge together with protons form the mass of the atom, as neutrons are neutral if the number does not affect the type of atom, but if its atomic mass changes.

Elements with the same atomic number, but different atomic mass, different number of neutrons are called isotopes; in general all elements have isotopes, for example hydrogen has an isotope called deuterium that has a neutral and another radioactive isotope called tritium that has two neutrons.

In conclusion using the characteristics of the atomic nucleus we find the answer for the effect of the change of neutrons in an atoms is

The change in neutrons changes the atomic mass.

electromagnetic force, and the number of nucleons involved in the fusion in your answer.
Help me on thiss one once again ughh ! asap ! hurry

Answers

The binding energy per nucleon increases in value from Hydrogen up to Iron (Fe 56). This causes lighter nuclei to fuse together to make more stable heavier nuclei.

The strong nuclear force is responsible for causing the fusion of the nuclei and it is much much stronger than the electromagnetic force that would otherwise keep the positive protons apart.

How is ice more reflective than water??​

Answers

Answer:

Because it has more texture and is solid. Its like glass

Explanation:

Answer:

Why is ice more reflective (has higher albedo) than liquid water? They're both the same substance (water). Is something quantum mechanical involved?

Explanation:

In fact ice is slightly less reflective than water. The reflectivity is related to the refractive index (in a rather complicated way) and the refractive index of ice is 1.31 while the refractive index of water is 1.33. The slightly lower refractive index of ice will cause a slightly lower reflectivity. In both cases the reflectivity is about 0.05 i.e. at an air/water or air/ice surface about 5% of the light is reflected.

Mass refers to the gravitational force on the matter in contact with the surface of a planet. true or false

Answers

Answer:

False

Explanation:

The mass of something does not depend on gravity. A planet has a constant gravitational force. Earth's is 9,80 N/kg. The moon, on the other hand, is 1,6 N/kg. the number of kilograms of something doesn't change if you go from one planet to another and since mass is measured in kilograms, mass doesn't change, therefore it does not refer to gravity. Mass refers to the quantity of matter in an object. It is weight that refers to the gravitational force on an object, since it is measured in newtons, and the amount of newtons per kilogram changes from planet to planet due to different gravity constants
