According to Newton's second law, how are acceleration and mass related? Directly or indirectly when force is constant?

Answers

Answer 1

Answer:

Newton's second law of motion can be formally stated as follows. The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net Force in the same direction as the net force and inversely proportional to the mass of the object  

Explanation:

The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases

A 100 kg bag of sand has a weight on 100 N. When dropped its acceleration is what?

Answers

Answer:

The acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

Explanation:

We have,

Mass of a bag of sand is 100 kg

Weight of the bag of sand is 100 N

It is required to find the acceleration of the bag when it is dropped. The weight of an object is given by :

[tex]F =ma[/tex]

When it is dropped, a = g

[tex]g=\dfrac{F}{m}\\\\g=\dfrac{100}{100}\\\\g=1\ m/s^2[/tex]

So, the acceleration of the bag of sand is [tex]1\ m/s^2[/tex].

When a current flows through a light bulb, it emits 30 J light energy in 2 seconds, What is the power of the bulb?

Answers

I believe the answer is P= 15w

The power of the light bulb is 15 watts.

What is power ?

Power in physics is defined as the rate of energy per unit time or in other words the work done by any electrical appliance per unit time. Power is expressed as -

P = E/T where E is Energy and T is the time period.

How to calculate the value of power in the question ?

Given that the light bulb emits 30 J light energy in 2 seconds.

We have E = 30J and T = 2 seconds.

Therefore power(P) = Energy(E) / Time(T)

∴  P = 30 / 2 = 15 watts

Thus the power of the light bulb is 15 watts.

In a landfill, old biodegradable materials are breaking down while at the same time, new trash is being added daily. Which statement describes the relationship between a landfill and the mass of the Earth?

A.) The mass of the Earth increases and decreases depending on the amount of trash added to the landfill.

B.) The mass of the Earth decreases due to materials breaking down in the landfill.

C.) The mass of the Earth increases due to trash being added to the landfill.

D.) The mass of the Earth remains the same regardless of the amount of trash in the landfill.

Answers

Answer:

Ok, first, what is trash?

Trash can be different things, like organic stuff (remains of fruit or wood) or not-organic (like plastic)

Naturally, those things come from Earth, meaning that that:

The fruit is on Earth.

Someone eats the fruit

the rest is trowed in the trash

the trash is returned to some location on the Earth.

So the mass of the fruit is always in the Earth, this means that the mass of the Earth does not change by this process.

Now in the process of materials breaking down, those materials are being "absorbed" by the land, so the mass remains on the planet, this process also does not change the mass of the Earth.

D.) The mass of the Earth remains the same regardless of the amount of trash in the landfill.

At what point in a waterfall, do the drops of water contain the most gravitational potential energy?

Answers

Answer:

The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall

Explanation:

The drops of water contain the most gravitational potential energy at the top before they start falling.

At the top of the waterfall

Gravitation

At the top of the waterfall, the water drops have the most gravitational potential energy before they start falling as the water at the peak of the waterfall is higher in the Earth's gravitational field and has gravitational potential energy. The potential energy is converted to kinetic energy when it falls. As a result, energy is not created; it was always there, stored as potential energy.

Potential energy is energy that is stored and is determined by the relative positions of various pieces of a system. Kinetic energy is the energy that an item or particle has as a result of its movement.

What is Wien's displacement law ?

Wien's displacement law states that, the black-body radiation curve for different temperatures will have different peaks of wavelengths and the wavelength is inversely proportional to the surface temperature.

Here,

According to Wien's displacement law,

The wavelength of the star is inversely proportional to its surface temperature.

λ [tex]\alpha[/tex] 1/T

where T is the surface temperature.

Therefore, the star with lowest wavelength will have the highest surface temperature.

Consider the wavelengths of each stars given,

The increasing order of their wavelengths can be written as,

λ(Orange) > λ(Yellow) > λ(White) > λ(Blue)

Therefore the increasing order of their surface temperatures will be,

T(Blue) > T(White) > T(Yellow) > T(Orange)

Hence,

The order of the surface temperature of the stars, starting from the highest to the lowest is Y > X > W > Z.

Dinesh wants to launch a package over the garden wall to his friend on the other side. His plan is to set up a see-saw, put the package on one end and jump on the other end. Dinesh determines that he will land on the board with a force of 1,127 newtons, and the package weighs 322 newtons. The board he is going to use for the see-saw is 9 meters long. How close to the end of the board should Dinesh put the fulcrum?

Answers

Answer:

Dinesh should put the fulcrum 2 m from himself and 7 m from the package.

Explanation:

Let the fulcrum be x meters from Dinesh's end.

The sum of clockwise moment must balance the sum of anti-clockwise moment.

Taking a moment about the fulcrum

(Force exerted by Dinesh) × (Distance of Dinesh from the fulcrum) = (Weight of the package) × (Distance of the package from the fulcrum)

Force exerted by Dinesh = 1127 N

Distance of Dinesh from the fulcrum = x m

Weight of the package = 322 N

Distance of the package from the fulcrum = (9 - x) m

1127 × x = 322 (9 - x)

1127x = 2,898 - 322x

1127x + 322x = 2,898

1449x = 2898

x = (2898/1449) = 2 m

Hence, Dinesh should put the fulcrum 2 m from himself and 7 m from the package.

C. 21.8 m/s, 10.9 m/s
D. −10.9 m/s, 5.2 m/s

Answers

Answer:

10.9 m/s, −1.82 m/s

Explanation:

We have,

Anand gets into an elevator and travels 50 m straight up in a time of 5 s. He then travels in the opposite direction, straight down, for 70 m in a time of 6 s.

Total time of journey is 11 seconds.

Total distance is 50 m + 70 m = 120 m

Total displacement is 50 m - 70 m = -20 m

Average speed, [tex]s=\dfrac{120\ m}{11\ s}=10.9\ m/s[/tex]

Average velocity, [tex]v=\dfrac{-20\ m}{11\ s}=-1.82 \ m/s[/tex]

So, the correct option is (b) 10.9 m/s, −1.82 m/s.

When an atom in a reactant loses electrons, what happens to its oxidation number?
A. Its oxidation number decreases
B. Its oxidation number doubles.
C.Its oxidation number increases.
D.Its oxidation number increases by one.
E. Its oxidation number stays the same.

Answers

It would be e because Reduction happens when an element gains electrons; in this case, its oxidation number is lowered. For example, when iron rusts, oxygen can behave as an oxidizing agent. As the oxygen gains electrons, it changes from an oxidation number of zero to an oxidation number of negative two.

one electrons carries a charge of 1.6 x 10⁻¹⁹ Coulomb
