a metal coin has certain properties that can be measured.which property of a coin is different on the moon that is on earth?

Sloan [31]

Answer:

Coins weigh less on the Moon.

Explanation:

Gravity is only 1/6th as strong on the Moon than it is on Earth. Where a nickle is about 5 grams on Earth, it is less than 1 gram on the Moon. Gravity is affected by the size of the planet or moon. The Moon is much less massive than the Earth.

How would you describe the stability of the atmosphere if you noted a dry adiabatic rate of 10ºC/1000 meters, a wet adiabatic ra

muminat

Answer:

conditional instability (Γd > Γe > Γw)

Explanation:

Given;

dry adiabatic rate, Γd = 10ºC/1000 meters

wet adiabatic rate, Γw= 6.5ºC/1000 meters

environmental lapse rate, Γe = 7.8ºC/1000 meters

Stability of the atmosphere can be described as Absolute stability, Absolute instability or conditional instability.

Conditions for Absolute stability:

Γd > Γw > Γe

Conditions for Absolute instability:

Γe > Γd > Γw

Conditions for conditional instability:

Γd > Γe > Γw

Thus, conditional instability satisfies the given values of the atmospheric condition: Γd (10) > Γe (7.8) > Γw (6.5)

S1.1 The Acre-Foot. Hydraulic engineers in the United States often use, as a unit of volume of water, the acre-foot, defined as

Mars2501 [29]

Answer:

1072 acre foot

1331424000 kg

Explanation:

1 feet has 12 inches, so 2 in is 0.167 feet.

1 km^2 has 1 million m^2.

1 acre is 4074 m^2.

So, 1 km is 247 acres.

Then 26 km^2 is 6422 acres.

So, the volume of water is

6422 * 0.167 = 1072 acre-foot

Since one cubic meter of water has 1000 kg

One inch is 25.4 mm = 0.0254 m

One feet is 12 * 0.0254 = 0.3048 m

An acre-feet has a volume of

4074*0.3048 = 1242 m^3

And that is a mass of water of

1242 * 1000 = 1242000 kg/acre-feet

Therefore the mass of rainwater in the town is of

1072 * 1242000 = 1331424000 kg = 1331424 tons

A particle moves along a circular path of radius 300 mm. If its angular velocity is θ = (2t) rad/s, where t is in seconds, deter

uysha [10]

Answer:

4.83m/ $s^{2}$

Explanation:

For a particle moving in a circular path the resultant acceleration at any point is the vector sum of radial and the tangential acceleration

Radial acceleration is given by $a_{radial}=w^{2}$ r

Applying values we get $a_{radial}=(2t)^{2}$ X0.3m

Thus $a_{radial}=1.2t^{2}$

At time = 2seconds $a_{radial}= 4.8m/s^{2}$

The tangential acceleration is given by $a_{tangential} =\frac{dV}{dt}=\frac{d(wr)}{dt}$

$a_{tangential}=\frac{d(2tr)}{dt}$

$a_{tangential}= 2r$

$a_{tangential}=0.6m/s^{2}$

Thus the resultant acceleration is given by

$a_{res} =\sqrt{a_{rad}^{2}+a_{tangential}^{2}}$

$a_{res} =\sqrt{4.8^{2}+0.6^{2} } =4.83m/s^{2}$
