Explain in your OWN words what erosion mass wasting means
marishachu [46]

Explanation:

Erosion is the physical removal and transportation of weathered material by water, wind, ice, or gravity. Mass wasting is the transfer or movement of rock or soil down slope primarily by gravity. Rock falls, slumps, and debris flows are all examples of mass wasting.

Two long, straight wires are parallel and 10 cm apart.One carries a current of 2.0 A, the other a current of 5.0A. (a) If the tw
lubasha [3.4K]

Answer:

Explanation:

Given

Distance between two wires d=10 cm

Current value i_1=2 A

i_2=5 A

(a)If current flows in opposite direction

When current Flows in opposite direction the two wires will repel each other

Force due to current carrying wire F=\frac{\mu _0i_1i_2}{2\pi r}

F_{12}=F_{21}=\frac{\mu _0\times 2\times 5}{2\times \pi \times 0.1}

F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}

F_{12}=2\times 10^{-5} N (Repulsive Force)

(b)If current is flowing in the same direction

When direction of current is same then force will be attractive in nature

F_{12}=F_{21}=\frac{\mu _0i_1i_2}{2\pi r}

F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}

F_{12}=2\times 10^{-5} N (attractive Force)

A baseball has a mass of 0.145 kg. A professional pitcher throws a baseball 67 mi/h, which is 30.0 m/s. What is the magnitude of
Kamila [148]

The concept of momentum tells us that it is equivalent to the product between the mass and the velocity of the object, that is to say that in general it can be written as

p = mv

Where,

m = mass

v = Velocity

Our values are given as,

m = 0.145kg

v = 67mi/h = 30m/s

Replacing we have that,

p = (0.145)(30)

p = 12.45 kg\cdot m/s

Therefore the magniude of the momentum of the pitched baseball is 12.45 kg\cdot m/s

A football is left on the field outside during the winter months, the next morning the football was partially deflated. Using wh
jenyasd209 [6]

Answer:

B  

Volume decreases due to less molecular motion of the gas inside the football.

Explanation:

Assuming that the atmospheric pressure (and therefore, the pressure of the air inside the football) remains constant, this means that we can apply Charle's law, which states that:

"For a fixed amount of gas kept at constant pressure, the volume of the gas is proportional to its absolute temperature"

Mathematically:

\frac{V}{T}=const.

where

V is the volume of the gas

T is its absolute temperature

In the winter month, the air becomes colder, which means that the temperature of the air (and of the gas inside the football) decreases. As the average kinetic energy of the molecules of a gas is proportional to its absolute temperature, this also means that there will be less molecular motion in the gas, and therefore (as stated by Charle's law) the volume of the gas also decreases.
