The pressure was 50pa ,when a perpendicular force was applied on a surface area of 2.5m2.what is the force applied??????​

Answers

Answer 1

Answer:

Force = 125 Newton

Explanation:

Given the following data;

Pressure = 50 pa

Area = 2.5 m²

To find the force applied;

Force = pressure * area

Substituting into the formula, we have;

Force = 50 * 2.5

Force = 125 Newton

WHICH OBJECT?

When the C4 key on a piano keyboard is pressed, a string inside the piano is struck by a hammer and begins vibrating back and forth at approximately 260 cycles per second.
a. What is the frequency in Hertz of the sound wave?
b. What is the wavelength of the wave?

Answers

Answer:

Frequency = 260 Hz and wavelength = 1.31 m

Explanation:

Given that,

A hammer begins vibrating back and forth at approximately 260 cycles per second.

(a) The frequency of an object is the number of vibrations per unit time. The frequency of the sound wave is 260 Hz.

(b) The speed of sound in air is 343 m/s. So,

[tex]v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{343}{260}\\\\\lambda=1.31\ m[/tex]

Hence, this is the required solution.

You flip a coin straight up if the coin reaches a high point of 0.25 m above where you released it what was the initial speed?

Answers

Answer: 2.21 m/s

Explanation:

Given

Coin reaches a height of  0.25 m above the launch point

Suppose u is the initial speed of the coin

Using the equation of motion

[tex]\Rightarrow v^2-u^2=2as\\[/tex]

Putting values

[tex]\Rightarrow 0^2-u^2=2\times g\times s=2\times (-9.8)\times 0.25\\\Rightarrow u^2=4.9\\\Rightarrow u=2.21\ m/s[/tex]

Thus, the initial velocity is 2.21 m/s

What is the acceleration of a 24 kg mass pushed by an 8 N force?

Answers

Answer:

0.25 m/s squared

Explanation:

Mass of the body (m)= 24kg

Applied force on the body(F)= 6N

Acceleration of the body (a)= ?

Solution

F = ma

a = F/m

a = 6N/24kg

a = 0.25m/s^2

Answer: The acceleration of the body is 0.25m/s^2

I hope this helps

Answer:

[tex]\boxed {\boxed {\sf a=\frac {1}{3} \ m/s^2}}[/tex]

Explanation:

Force is the product of mass and acceleration.

[tex]F=ma[/tex]

The mass is 24 kilograms and the force is 8 Newtons. Let's convert the Newtons to make the problem easier.

1 Newton is equal to 1 kilogram meter per square second. The force of 8 N equals 8 kg*m/s²

Substitute the known values into the formula.

[tex]8 \ kg*m/s^2= (24 \ kg )*a[/tex]

Since we are solving for a, we must isolate the variable. It is being multiplied and the inverse of multiplication is division. Divide both sides by 24 kilograms.

[tex]\frac {8 \ kg*m/s^2}{24 \ kg}= \frac{(24 \ kg )*a}{24 \ kg}[/tex]

The kilograms will cancel, hence our earlier unit conversion.

[tex]\frac {8 \ m/s^2}{24 }= a[/tex]

[tex]\frac {1}{3} \ m/s^2=a[/tex]

The acceleration is 1/3 meter per square second.

C.
Can the wave travel through a vacuum?


D.
Can the wave travel through a liquid?

Answers

Answer:

A.  Can the wave transfer matter?

Explanation:

EMW is made by vibrations of the charged particles and they work on a mechanical waveform. The energy is transferred through a vacuum and thus they need a medium to pass the energy.  Thus in order to transport the energy from one place to another, such as a sound wave. Hence first she should have knowledge about the chemical and physical properties of the waves such as can they transfer matter.

Answers

Answer:

During photosynthesis solar energy is converted into chemical energy

Explanation:

During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.

ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.

ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.

The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.

These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).

ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.

Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.

Chlorophyll molecules entrap solar energy . There are 2 types of photo-systems in chlorophyll. These are photo-system -I and photo-system-II .

The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.

During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.

Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.

The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.

Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

If the pelican was traveling 8.79 m/s but was only 2.7 m above the water, how far would the fish travel horizontally before hitting the water below?

Answers

Answer:

6.52m

Explanation:

The horizontal distance travelled is known as its range. This is expressed as;

Range = u* √2H/g

u is the speed of the pelican

H is the maximum height

g is the acceleration due to gravity

Range = 8.79*√2(2.7)/9.8

Range = 8.79 * √5.4/9.8

range = 8.79*√0.5510

Range = 8.79*0.7423

Range = 6.52

Hence the fish will travel 6.52m before hitting the water below

A centrifuge used in DNA extraction spins at a maximum rate of 7000rpm producing a "g-force" on the sample that is 6000 times the force of gravity. If the centrifuge takes 10 seconds to come to rest from the maximum spin rate: a) What is the angular acceleration of the centrifuge? b)what is the angular displacement of the centrifuge during this time

Answers

Answer:

A) a = 73.304 rad/s²

B) Δθ = 3665.2 rad

Explanation:

A) From Newton's first equation of motion, we can say that;

a = (ω - ω_o)/t. We are given that the centrifuge spins at a maximum rate of 7000rpm.

Let's convert to rad/s = 7000 × 2π/60 = 733.04 rad/s

Thus change in angular velocity = (ω - ω_o) = 733.04 - 0 = 733.04 rad/s

We are given; t = 10 s

Thus;

a = 733.04/10

a = 73.304 rad/s²

B) From Newton's third equation of motion, we can say that;

ω² = ω_o² + 2aΔθ

Where Δθ is angular displacement

Making Δθ the subject;

Δθ = (ω² - ω_o²)/2a

At this point, ω = 0 rad/s while ω_o = 733.04 rad/s

Thus;

Δθ = (0² - 733.04²)/(2 × 73.304)

Δθ = -537347.6416/146.608

Δθ = - 3665.2 rad

We will take the absolute value.

Thus, Δθ = 3665.2 rad
