FITT principle:

Frequency-is how regular or often a person does the plan of a target health-related physical activity. It depends on how determined you want to accomplish your target. The more often you train, the faster the result.


Intensity - is how hard a person exercise during a physical activity period. It can be measured in different ways, depending on the health-related component. For example, monitoring heart rate is one way to measure the intensity during aerobic endurance activities, but does not indicate intensity during flexibility activities. The harder you work, the faster your heart beats.


Time - is the duration of the physical activity. Together with the other aspects of the FITT principle, time varies depending on the target health-related fitness component. For example, in developing flexibility, stretching may take 10-30 seconds for each activity, while the minimum time for performing an aerobic exercise is 20 minutes of continuous action.


Type - refers to the physical activity chosen to improve a specific component of health-related fitness. Different events require different training programs. For example, if a person wants to increase core muscles, he or she must do exercises that target the oblique muscles, while another person wishing to improve his or her cardiovascular endurance needs to jog, run, swim or perform some other aerobic activities.

The time the ball spend on the air before reaching the ground is 2.325 seconds.

The kinematic formula would be most useful to solve for the target unknown is

H = ut + ½gt²

Basket ball is drop from height

H=10m

It is dropped on planet mass

And the acceleration due to gravity on Mars is given as

g= 3.7m/s²

Time taken for the ball to reach the ground

Initial velocity of the body is zero

u=0m/s

Using equation of motion: free fall

H = ut + ½gt²

10 = 0•t + ½ × 3.7 ×t²

10 = 0 + 1.85t²

10 = 1.85t²

Then, t² =10/1.85

t² = 5.405

t = √ 5.405

t = 2.325seconds

So the time the ball spend on the air before reaching the ground is 2.325 seconds.

According to internal energy, the final volume is 19.75 liters.

We need to know about internal energy to solve this problem. For a closed system, with matter transfer excluded, the changes in internal energy are due to heat transfer and due to thermodynamic work done by the system on its surroundings. It can be determined as

ΔU = Q - W

where ΔU is the change in internal energy, Q is heat and W is work done.

From the question above, we know that

ΔU = -325 J

Q = 155 J

Vo = 15 L = 0.015 m³

P = 1 atm = 1.01 x 10⁵ Pa

By substituting the given parameter, we can calculate the work done

ΔU = Q - W

-325 = 155 - W

W = 480 joule

Find the final volume

W = P . (Vi - Vo)

480 = 1.01 x 10⁵ (Vi - 0.015)

Vi = 0.01975 m³

Vi = 19.75 liters

Answer: The car is travelling at a constant speed. Because it travells 30 miles in 30 minutes. While it travells 40 miles in 40 minutes.

Explanation:

Since an electron cannot be fractionalized, any number that is a multiple of 1.6 is true. Therefore, the appropriate options are -3.2x10-19C, -4.8x10^-19C and -8.0x10-19C.

Matter's electric charge is what gives it a force when it's in an electromagnetic field, which is its physical property.

Protons and electrons, which act as charge carriers, frequently carry both positive and negative electric charges. Charges moving around in a system produce energy.

-1.2x10^-19C in choices is incorrect even if it is a multiple of 1.6 since it has a fraction of one electron because its charge is less than that of a single electron.

Consequently, the values of 1.2x10-19, 5.6x10-19, and -9.4x10-19 are wrong because they contain fractions of electrons that are impossible to exist.

The heat generated by the Earth would keep passing radially outward from the Earth's surface into space if the natural greenhouse effect did not exist, and the Earth would have an average temperature of about -20°C.

The greenhouse effect describes how "greenhouse gases" trap heat near the Earth's surface.

These heat-trapping gases act like a blanket wrapped around Earth, keeping it warmer than it would be without them.

Earth would turn into an icy wasteland if greenhouse gases were not present.

Greenhouse gases maintain our planet habitable by retaining some of the Earth's heat energy, preventing it from escaping into space. The greenhouse effect is the sequestration of heat.

Thus, the greenhouse effect can decrease the temperature of the Earth below average.

The Speed(s) of a car traveling is = 36 km/h west

Distance(d) to the concert is = 12km

Time to get there = t hours

The formulae used are

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

⇒Time(t) = Distance(d) / Speed(s)

Resolving power is most improved by increasing the distance between telescopes.

Relatively close objects, such binary stars or individual galaxies’ stars, occupy very small angles on telescopes. We require really huge apertures to resolve them. The resolving power of telescope is calculated by Rayleigh's formula,

So, resolving power = 1/∆θ = d/1.22λ

The reciprocal of the smallest angle occupied at the telescope’s objective lens by two point objects that can just be recognised as distinct is the definition of a telescope’s resolving power.

The object strikes 40.0 meters far from the base of the cliff on the ground.

Let us assume that the object strikes the ground after a time equal to 't' seconds. And horizontal distance covered by it in 't' seconds is x meters. The vertical distance traveled by it in 't' second would be equal to the height of the cliff.

Vertical distance traveled = s = 122.5m

Initial vertical speed = u = 0 m/s

Acceleration due to gravity = g = 9.8 m/s²  

By using the second equation of motion:

s = ut + 1/2gt²

Put in the value

122.5 = (0)t + 1/2(9.8)t²

122.5 = 0 + 4.9t²

t² = 122.5/4.9

t² = 25

t =√25

t = 5 seconds

Horizontal speed = v = 8.0 m/s

Time taken = t = 5 s

Acceleration = 0 m/s

Using the formula, distance = speed ×  time

x = v × t

x = 8.0 × 5

x = 40.0 m

Therefore the object strikes 40.0 meters far from the base of the cliff on the ground.

100hz, 247hz, 750hz

Then the accurate Nyquist frequency can be taken out as

fs = 2 fmax

The sampling theorem is another name for the Nyquist theorem. The rule is that a pure sine wave measurement, or sample rate, must be at least twice as frequent as the original to be accurately reproduced.

Nyquist explains that we can send data at a rate of up to C=2Blog2M bits per second in a channel with no noise. B is seen as the bandwidth (in Hz) and M is the number of signal levels.

The Nyquist frequency can be defined as fn = 1/2t. When spectra for digital data are displayed, the highest frequency displayed is the Nyquist frequency.

The pace at which an object's direction changes as it is traveling, as observed from a particular viewpoint and as quantified by a certain unit of time, is known as its velocity.

Any object exposed to forces will accelerate. The object's velocity is altered as a result of this acceleration. The speed of the entity prior to the change imposed on by acceleration is therefore known as the initial velocity.

The final pressure of the gas is p2 = 2.085 * 10^5 pa.

Boyle's law is a gas law that states that the pressure exerted by a gas (of a given mass at a constant temperature) is inversely proportional to the volume it occupies. That is, if the temperature and quantity of gas are constant, the pressure and volume of the gas are inversely proportional.

Boyle's Law states that a change in the volume occupied by a gas (at a constant amount and temperature) leads to a change in the pressure exerted by the gas. The following mathematical formulation of this law is possible:

P1V1 = P2V2
