Answer:Decreases

Explanation:

Given

Volume is held constant that is it is a isochoric process.

We know that

PV=nRT

as n,V& R are constant therefore only variables are

P & T

so $\frac{P_1}{T_1}=\frac{P_2}{T_2}$

$\frac{P_1}{P_2}=\frac{T_1}{T_2}$

As $T_1$ is decreasing therefore Pressure must also decrease so that ratio remains constant.

Which characteristic do arid and polar regions share?

Setler79 [48]

few plants

Explanation:

Arid and polar regions of the world typically have few plant species. The plant species in such environment are called xerophytes. They are plants that can live in an area with little to no precipitation.

Arid regions of the world are about the most driest in the world with very high diurnal temperature range.
Polar regions are frigid and cold all year round.
Both arid and polar regions have little to no precipitation all year round.
They have poor soils to support plant growth.
This is why they both have few plants.

It takes four hydrogen nuclei to create one helium nucleus in the proton–proton chain, which is the main energy source of the Su

Artyom0805 [142]

Answer:

0.1371 * 10 ^ -27 kg

Explanation:

From the question number of hydrogen nuclei used to form 3 Helium nuclei = 12 ( 4 * 3 )

mass of the 12 hydrogen nuclei = 12 *( 1.6726 *10^-27) = 20.0712 * 10 ^-27

mass of single helium = 6.6447 * 10 ^-27 kg

therefore the mass of the 3 helium = 3 *( 6.6447 *10 ^-27) = 19.9341 * 10 ^-27 kg

The mass difference between the hydrogen and the helium used

= (20.0712 * 10^ -27) - (19.9341 * 10 ^-27) = 0.1371 * 10 ^ -27 kg

therefore 0.1371 * 10^-27 kg is converted into energy to create the three helium nuclei

DIA [1.3K]

To develop this problem we will apply the linear motion kinematic equations. Specifically, the second law that describes the position of a body as a function of its initial velocity, time and acceleration.

$y = ut+\frac{1}{2}gt^2$

Here,

u = Initial velocity

t = Time

g = Acceleration due to gravitation

If we replace the values to find the gravitational acceleration we have then,

$1.7m = 0+\frac{1}{2} g*0.36^2$

$g= 26.2346m/s^2$

Recall that the force of gravity on the planet Jupiter is 24.79 m / s² so the measure is closer to this planet. It is likely that you are in Jupiter.

What is the power generation in a machine that produces 76 j in 3.7s

ICE Princess25 [194]

Power is the ratio between energy and time:
$P= \frac{E}{t}$
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
$P= \frac{76 J}{3.7 s} =20.5 W$
