What disperses seeds?

People, animals, water, and the wind
People, water, cars, and the wind
Animals, water, wind, and the sun
Water, wind, heat, and people

Answers

Answer 1
The answer would be :People, animals, water & the wind.
The reason as to why these would be the answer is because the wind disperses seeds by blowing them through the air to different locations. The water washes the seed away to a location away from the parent. Animals disperse seeds, when they leave behind their waste and the seeds are in the waste. Lastly people disperse seeds in many ways, but one of them would be like throwing them into the grass, and ir planting them.

Predict what would happen to the volume of a gas if the pressure on that gas were doubled and then the absolute temperature of that gas were doubled.

Answers

The new volume of the gas will remain the same.

Data obtained from the question Initial pressure (P₁) = PInitial temperature (T₁) = TInitial volume (V₁) = VNew pressure (P₂) = 2PNew temperature (T₂) = 2TNew Volume (V₂) =?

How to determine the new volume

The new volume of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

(PV) / T = (2P × V₂) / 2T

Cross multiply

T × 2P × V₂ = PV × 2T

2PT × V₂ = 2PVT

Divide both side by 2PT

V₂ = 2PVT / 2PT

V₂ = V

Thus, the new volume will remain the same

What is boyle's law?

Boyle's law states that if the temperature of a gas sample is constant, the volume of the sample will vary inversely as the pressure.  

This means an increase in pressure will lead to a decrease in volume, also a decrease in volume will lead to an increase in pressure.

Therefore, when the pressure on the piston is doubled, the gas moves downward in the piston until the pressure produced by the gas equals the pressure produced by the piston.  At this point, the volume of the gas will be reduced.

Answers

 The percentage error in his experimental value is -51.97%.

What is percentage error?

This is the ratio of the error to the actual measurement, expressed in percentage.

To calculate the percentage error of the student, we use the formula below.

Formula:

Error(%) = (calculated value-accepted value)100/(accepted............. Equation 1

From the question,

Given:

Calculated value = 4.15 g/cmaccepted value = 8.64 g/cm

Substitute these values into equation 1

Error(%) = (4.15-8.64)100/8.64Error(%) = -4.49(100)/8.64Error(%) = -449/8.64Error(%) = -51.97 %

Answer : 413.44N

Here it is given that an elevator is moving down with an acceleration of 3.36 m/ . And we are interested in finding out the apparent weight of a 64.2 kg man . For the diagram refer to the attachment .

From the elevator's frame ( non inertial frame of reference) , we would have to think of a pseudo force. The direction of this force is opposite to the direction of acceleration the frame and its magnitude is equal to the product of mass of the concerned body with the acceleration of the frame . When a elevator accelerates down , the weight recorded is less than the actual weight .

From the Free body diagram ,

This question involves the concepts of Newton's Second Law of Motion.

The force delivered to the froghopper as it makes the jump is "0.0792 N".

NEWTON'S SECOND LAW OF MOTION

According to Newton's Second Law of Motion whenever an unbalanced force is applied to an object, acceleration is produced in it in the direction of the force. Mathematically,

F = ma

where,

F = Force delivered to the grasshopper = ?m = mass of the grasshopper = 1.98 x 10⁻⁵ kga = acceleration = [tex]\frac{\Delta v}{t}[/tex]Δv = change in velocity = 4 m/s - 0 m/s = 4 m/st = time = 0.001 s

Therefore,

[tex]F= ma = m\frac{\Delta v}{t}\\\\F = (1.98\ x\ 10^{-5}\ kg)(\frac{4\ m/s}{0.001\ s})\\\\[/tex]

Several trials are conducted, and the average and 95% confidence interval are calculated. The mass determined using this other balance scale does NOT agree with the mass measured on a digital scale. Is it possible that the balance scale and the electric scale are accurate, and the lack of agreement was just random?

Radioactive decay

In nuclear physics, beta decay is a type of radioactive decay in which a beta particle is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide

Answer:

In alpha decay, mass number of the nucleus decreases by 4 unit and atomic number is decreased by 2 unit. Alpha decay : ZAX→Z−2A−4Y+24He. When a parent nucleus emits an electron (beta particle) along with the daughter nucleus, then the nuclear reaction thus is called as beta decay.

Adam and kevin are roommates. Adam can clean their apartment in 45 minutes. Kevin can clean it in 60 minutes. Rounded to the nearest minute, how much time will it take if they work together?.

Answers

If you add both numbers together it makes 105 but we’re talking time so it’ll be an hour and 45 minutes for them to clean their apartment.

If they work together, required time to clean the apartment will be 26 minutes.

What is time and work problems in mathematics?

Time and work are concerned with the amount of time it takes a person or a group of people to complete a task and the effectiveness of the work performed by each of them.

Given parameters:

Adam can clean their apartment in 45 minute

Kevin can clean it in 60 minutes.

So, in 1 minute,  Adam can clean 1/45 part of their apartment.

and, in 1 minute, Kevin can clean 1/60 part of their apartment.

If they work together, in 1 minute, they  can clean = (1/45 + 1/60) part of apartment.

=(4+3)/180 part of apartment.

= 7/180 part of apartment.

Hence,  if they work together, the apartment can be cleaned in 180/7 minutes, that is, in 26 minutes.

A 5.0 kg Foucalt Pendulum swings at the end of a 4.0 m long cable. The pendulum is released from a height of 1.5 m above the lowest position of its swing. What is the maximum tension in the cable?

Answers

Hi there!

We can begin by solving for the pendulum's velocity at the bottom of its trajectory using the work-energy theorem.

Recall:
[tex]E_i = E_f[/tex]

Initially, we just have Potential Energy. At the bottom, there is just Kinetic Energy.

[tex]PE = KE\\\\[/tex]

Working equation:
[tex]\large\boxed{mgh = \frac{1}{2}mv^2}[/tex]

Rearrange to solve for velocity:
[tex]gh = \frac{1}{2}v^2\\\\v = \sqrt{2gh}\\\\v = \sqrt{2(9.8)(1.5)} = 5.42 \frac{m}{s}[/tex]

Now, we can do a summation of forces:
[tex]\Sigma F = T - W[/tex]

The net force is the centripetal force, so:
[tex]\frac{mv^2}{r} = T - W[/tex]

Rearrange to solve for tension:
[tex]T = \frac{mv^2}{r} + W\\\\T = \frac{5(5.42^2)}{4} + 5(9.8) = \boxed{85.75 N}[/tex]

Answer:

Explanation:

Specific heat has a unit that describes the amount of heat (J) is required to raise a unit mass (g) by 1 degree temperature (C),  It should take the form of J/(g*C) if we stick with the metric units provided in the question.  Be aware that specific heat can be written in many different formats, all equivalent, but with differing measures.  Examples:

(BTU/kgC)

kJ/(mole*K)

J/(g*C)

and so on.  The specific heat for a material can be expressed in any of these formats.  There are all equivalent, just expressed with different units.

--------------

In this problem:  (150J)/[(100g)*(5C)] = 0.300 J/(g*C)

An accurate value of specific heat may be used for identification of the metal.  The closest I found is Barium (0.290 J/(g*C) and Zinc (0.388 J/(g*C)
