Answer:

The Answer is B because primary consumers need to get their food from plants

Explanation:

Answer:

1.F = 256 N

2.a = 8 m/s/s

By looking at the given information, you know force, and an acceleration. Therefore you have enough information to use the first formula.

F = ma

256 N = m * 8 m/s/s

m = 256 N/8 m/s/s

m = 32 Kg

Heat always flows through from a higher thermodynamic potential to lower thermodynamic potential.

It can be defined as the branch of science that deals with the interactions of thermal energy across different system and their surroundings.Thermodynamics does not deal with the rate of energy interaction.The movement of the thermal energy depends on the thermodynamic potential of the respective objects or bodies in which the flow of the thermal energy is involved.

The thermodynamics potential is analogous to the electrical potential what is used to flow the current in the electrical circuit in the similar fashion the temperature gradient is the driving force that is used for the transfer of heat energy from a higher temperature potential to the lower to a temperature potential.
This natural flow of heat is valid only when any external work is not done on the thermodynamic system where transfer of heat taking place .

This principle of heat transfer is not applicable in the case of refrigerator and air-conditioner because in that case some external work is done on the system and is the natural driving force of heat transfer.

Hence,we can say that heat always flows through from a higher thermodynamic potential to lower thermodynamic potential unless until some external prime mover is provided for example in case of air conditioner.

Answer:

Final momentum after a head on collision is -2kgm/

Explanation:

  One ball moves to the right and the other moves opposite  and momentum is a vector quantity so that considering the direction

Initial momenta are        P₁=2x3=6kgm/s        P₂=4x(-2)=-8kgm/s      

Final momentum is the vector sum of P(final)= 6-8= -2 kgm/s

Answer:

The depth of the object below the surface of the liquid is 0.510 meters.

Explanation:

The hydrostatic pressure ([tex]P[/tex]), measured in pascals, experimented by the object is directly proportional to density of the fluid ([tex]\rho[/tex]), measured in kilograms per cubic meter, gravitational acceleration ([tex]g[/tex]), measured in meters per square second, and depth of the object ([tex]h[/tex]), measured in meters. That is:

[tex]P = \rho\cdot g \cdot h[/tex] (1)

If we know that [tex]P = 4500\,Pa[/tex], [tex]\rho = 900\,\frac{kg}{m^{3}}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the depth of the object is:

[tex]h = \frac{P}{\rho\cdot g}[/tex]

[tex]h = \frac{4500\,Pa}{\left(900\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]

[tex]h = 0.510\,m[/tex]

The depth of the object below the surface of the liquid is 0.510 meters.

The depth of the object below the liquid's surface will be

"0.510 m".

According to the question,

Object immersed, P = 4500 Pa

Density of liquid, ρ = 900 kg/m³

Acceleration due to gravity, g = 9.8 m/s²

We know the relation,

→ Hydrostatic pressure (P) = ρ.g.h

or,

Depth will be:

→ h = [tex]\frac{P}{\rho .g}[/tex]

By substituting the values,

     = [tex]\frac{4500}{900\times 9.8}[/tex]

     = [tex]\frac{4500}{8820}[/tex]

     = 0.510 m

Thus the above answer is appropriate.

Answer:

Aerobic exercise is any type of cardiovascular conditioning. It can include activities like brisk walking, swimming, running, or cycling. You probably know it as “cardio.”

By definition, aerobic exercise means “with oxygen.” Your breathing and heart rate will increase during aerobic activities. Aerobic exercise helps keep your heart, lungs, and circulatory system healthy.

Aerobic exercise differs from anaerobic exercise. Anaerobic exercises, such as weightlifting or sprinting, involve quick bursts of energy. They’re performed at maximum effort for a short time. This is unlike aerobic exercises. You perform aerobic exercises for a sustained period of time.

Explanation:

Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" is defined as "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism

Answer:

Heat supplied should be equal to zero.

Explanation:

Given that a compressed gas is held inside a canister with a moveable lid. The temperature of the gas is significantly higher than the air temperature outside the canister. When weight is removed from the lid, the gas

expands to lift it.

For this expansion to be as nearly adiabatic as possible, one of the conditions that should be met is that there should be no supply of thermal or heat energy to the system.

According to first law of thermodynamics:

Change in internal energy = heat supply + work done by the system

If heat supplied = 0

Then, nothing is constant.

The internal energy = work done by the system.

Therefore, no heat should be supplied to the system.

Explanation:

The balanced nuclear reaction is shown by the following: ²³⁷₉₃ Np[tex]\rightarrow[/tex]⁴ ₂He +²³³₉₅ Am nuclear fission reaction.

There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.

In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.

In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Explanation:

From the question,

Speed (S) = Distance(d)/Time(t)

S = d/t....................... Equation 1

Make d the subject of the equation

d = St..................... Equation 2

Given: S = 50 km/s = 50000 m/s, t = 5 minutes = 5*60 seconds = 300 seconds

Substitute these values into equation 2

d = 50000(300)

d = 15000000 m

Hence the skier travels 15000000 m

Explanation:

Activity: Is it the same?!

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool (see Figure 1), and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions.

Some of the earliest accounts of light reflection originate from the ancient Greek mathematician Euclid, who conducted a series of experiments around 300 BC, and appears to have had a good understanding of how light is reflected. However, it wasn't until a millennium and a half later that the Arab scientist Alhazen proposed a law describing exactly what happens to a light ray when it strikes a smooth surface and then bounces off into space.

In this activity you will be working as an engineer that is working to modify different kinds of digital cameras and to study the effect of changing incident angle on the reflected angle.

Answer:

T = 10 seconds

Explanation:

Given that,

A remote car makes 2 revolutions in 20 seconds.

We need to find the period of the object.

It means, it will make [tex]\dfrac{2}{20}=0.1\ \text{revolutions/second}[/tex] .

lt T be the period of the object. So,

[tex]T=\dfrac{1}{0.1}\\\\T=10\ s[/tex]

It will take 10 seconds for one revolution.
