The absolute temperature of a gas is t. in order to double the rms speed of its molecules, what should be the new absloute tempe
jenyasd209 [6]

The new absloute temperature should be 4t.

<h3>Temperature </h3>

The hotness of matter or radiation is expressed by the physical quantity known as temperature.

There are three different types of temperature scales: those, like the SI scale, that are defined in terms of the average translational kinetic energy per freely moving microscopic particle, like an atom, molecule, or electron in a body; those that solely depend on strictly macroscopic properties and thermodynamic principles, like Kelvin's original definition; and those that are not defined by theoretical principles but rather by useful empirical properties of particula.

Using a thermometer, one can gauge temperature. It is calibrated using different temperature scales, each of which historically defined itself using a different set of reference points and thermometric materials.

A charge of 1. 5 µC is placed on the plates of a parallel plate capacitor. The change in voltage across the plates is 36 V. How
ELEN [110]

It is a type capacitor is in which two metal plates arranged in such a way so that they are connected in parallel . The potential energy is stored in the capacitor will be 2.7×10⁻⁵.

<h3>What is parallel plate capacitor ?</h3>

It is an type capacitor is an in which two metal plates arranged in such a way so that they are connected in parallel and have some distance between them.

A dielectric medium is a must in between these plates. helps to stop the flow of electric current through it due to its non-conductive nature .

The given data in the problem is;

Q is the charge= 1.5 µC

V is the change in voltage across the plates is = 36 V.

U is the potential energy=?

The formula for the potential energy is given by;

\rm U= \frac{1}{2} \times Q \times V \\\\ \rm U= \frac{1}{2} \times 1.5\times 10^{-6} \times 36 \\\\  \rm U=2.7\times10^{-5}

Hence the potential energy is stored in the capacitor will be 2.7×10⁻⁵.

How do we maintain heat in our body ?​
zysi [14]

Answer:

When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

Explanation:

The system can respond to internal and external influences and make adjustments to keep your body within a degree or two of your normal. The hypothalamus and your autonomic nervous system work with your skin, sweat glands, muscles and even your blood vessels to keep your temperature normal. As in other mammals, thermoregulation is an important aspect of human homeostasis. Most body heat is generated in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. Some nuts like peanuts, almonds, cashews, pistachios, and dates are also beneficial in winter. These nuts speed up your metabolism and increase your body temperature, eventually making you feel hot.

What is the net force on this object A: 0 newtons b: 200 newtons c:400 newtons D:600 newtons
Ilya [14]

Answer:

100kg

Explanation:

Total force =400N+600N=1000N

As we have,

F=m×g

1000N=m×10m/s²

1000N÷10m/s²=m

m=100kg
