How does an environmental change (ex. hurricane, drought, etc.) affect the organisms that are adapted to the environment before

rjkz [21]

The environmental changes can will negatively affect different organisms differently, for example some organisms might die due to failure of the organisms to adapt to the new changes. Some organisms will be forced to migrate in order to counter these changes, this may lead to this organisms leaving their old living routine and adapt to the new methods of living, this may lead to evolution caused by new environment.

According to the second law of thermodynamics, it is impossible for ____________. According to the second law of thermodynamics,

Tomtit [17]

Answer:

It's impossible for an ideal heat engine to have non-zero power.

Explanation:

Option A is incomplete and so it's possible.

Option B is possible

Option D is related to the first lae and has nothing to do with the second law.

Hence, the correct option is C.

The ideal engine follows a reversible cycle albeit an infinitely slow one. If the work is being done at this infinitely slow rate, the power of such an engine is zero.

We can also stat the second law of thermodynamics in this manner;

It is impossible to construct a cyclical heat engine whose sole effect is the continuous transfer of heat energy from a colder object to a hotter one.

This statement is known as second form or Clausius statement of the second law.

Thus, it is possible to construct a machine in which a heat flow from a colder to a hotter object is accompanied by another process, such as work input.

An empty rubber balloon has a mass of 12.5 g. The balloon is filled with helium at a density of 0.181 kg/m3. At this density the

Taya2010 [7]

Answer:

5.5 N

Explanation:

mass of balloon (m) = 12.5 g = 0.0125 kg

density of helium = 0.181 kg/m^{3}

radius of the baloon (r) = 0.498 m

density of air = 1.29 kg/m^{3}

acceleration due to gravity (g) = 1.29 m/s^{2}

find the tension in the line

the tension in the line is the sum of all forces acting on the line

Tension =buoyant force + force by helium + force of weight of rubber

force = mass x acceleration

from density = \frac{mass}{volume} , mass = density x volume

buoyant force = density x volume x acceleration

where density is the density of air for the buoyant force

buoyant force = 1.29 x (\frac{4]{3} x π x 0.498^{3}) x 9.8 = 6.54 N

force by helium = density x volume x acceleration

force by helium = 0.181 x (\frac{4]{3} x π x 0.498^{3}) x 9.8 = 0.917 N

force of its weight = mass of rubber x acceleration

force of its weight = 0.0125 x 9.8 = 0.1225 N

Tension = buoyant force + force by helium + force of weight of rubber

the force of weight of rubber and of helium act downwards, so they

carry a negative sign.

Tension = 6.54 - 0.917 - 0.1225 = 5.5 N

A proton and an electron are both accelerated to the same final speed. If λp s the de Broglie wavelength of the proton and e is

meriva

Answer:

Explanation:

The relation between the de Broglie wavelength and the momentum of the particle is given by

$\lambda =\frac{h}{m\times v}$

where, m is the mas of the particle and v be the velocity of the particle and h be the Plank's constant.

So, the de broglie wavelength of proton is given by

$\lambda _{p}=\frac{h}{m_{p}\times v}$ .... (1)

The de broglie wavelength of electron is given by

$\lambda _{e}=\frac{h}{m_{e}\times v}$ .... (2)

Divide equation (2) by equation (1), we get

$\frac{\lambda _{e}}{\lambda _{p}}=\frac{m_{p}}{m_{e}}$

As the mass of proton is much more than the mass of electron, so the de broglie wavelength of electron is more than the de Broglie wavelength of proton.

Why does the desert sand, next to a lake, heat up quicker than the water in the lakes

ICE Princess25 [194]

Water is a slow conductor of heat. Land absorbs heat quicker, so the sand next to the lake will heat up quicker than water.
