Why are New Hampshire students required to learn about earths systems

VashaNatasha [74]

Answer:

Explanation:

Why are students in Hawaii required to learn the history of debate surrounding the writing of the first 10 amendments to the constitution? They were not a member of the United States at the time?

The reason they have to learn anything they can about the constitution is because they are governed by it (just as you are).

The reason you have to learn about the Earth's Systems is because currently there is a huge debate about global warming. The problem is that we are not sure what the solution might be and we've already spent billions on reducing our effect on the environment. Billions means your tax dollars (many) or that of your parents. Many scientists are not sure we should be doing anything.

You will enter the work force one day and if you get a good job, you will be taxed. You should never be unaware of what your tax dollars are spent on.

A bag of potatoes has a mass of 2.5 kg. What is its approximate weight on Earth?

ad-work [718]

Weight = m (mass) * g (acceleration due to gravity)

g = 9.80 m/s^2
m = 2.5 kg = 2,500 g

Weight = 2,500 g * 9.80 m/s^2
Weight = 24,500 N

A standing wave on a string that is fixed at both ends has frequency 80.0 Hz. The distance between adjacent antinodes of the sta

OlgaM077 [116]

Answer:

v = 19.2 m/s

Explanation:

In order to find the speed of the string you use the following formula:

$f=\frac{v}{2L}$ (1)

f: frequency of the string = 80.0Hz

v: speed of the wave = ?

L: length of the string = 12.0cm = 0.12m

The length of the string coincides with the wavelength of the wave for the fundamental mode.

Then, you solve for v in the equation (1), and replace the values of the other parameters:

$v=2Lf=2(0.12m)(80.0Hz)=19.2\frac{m}{s}$

The speed of the wave is 19.2 m/s

Do objects with more mass have more friction

Nikitich [7]

Yes. An object of large mass is pulled down onto a surface with a greater force than an object of low mass and, as a consequence, there is greater friction between the surface of the heavy object than between the surface of the light object.

A person pulls a bucket of water up from a well with a rope. Assume the initial and final speeds of the bucket are zero (Vi-Vf-0

n200080 [17]

Answer:

This a closed system because the mass of the system is conserved

The energy system that undergoes change is the Potential energy system

The energy system diagram is shown on the first uploaded image

Work done = Change in gravitational potential energy

So solving algebraically for work done would be

Work done = $m*g*h$

where m is mass

g is acceleration due to gravity

and h is the height

Work done in terms of force and distance is = mg

where m is mass of bucket and

g is acceleration due to gravity

Explanation:

a) At the start, potential and kinetic energy were zero. so, energy is zero.

As the person pulls the bucket up, the potential energy becomes mgh.

so,final energy will be consisting of only potential energy.

B) Here work done is equal to change in gravitational potential energy.

W = $\Delta P.E$

W = m*g*h

where g = 9.9 m/ $s^2$

C) Work = force * distance

mgh = force * h

force = mg

force = weight of bucket
