Bright white shadings on infrared images indicate cloud tops that have relatively ________ temperatures

Maru [420]

Infrared is created by detecting the produced radiation coming off of clouds. The temperature of the cloud will define the wavelength of radiation produced from the cloud. The benefit of the infrared imagery is that can be used day and night to conclude the temperature of the cloud tops and earth surface structures and to get the general idea of how clouds are. Based on the general guidelines to define cloud features, if the cloud is bright white on infrared then it is a high cloud or has a cloud top that is developed high into the troposphere. In this way infrared images actually display patterns of temperature on a gray scale such that at one extreme dark gray is warm and at the other extreme bright white is cold. A color scale is used to portray temperature and some improved infrared images show two or more gray scale sequences. High cold clouds are brighter white than low warm clouds.

Two speakers emit the same sound wave, identical frequency, wavelength, and amplitude. What other quantity would be necessary to

Komok [63]

Answer:

Phase Difference

Explanation:

When the sound waves have same wavelength, frequency and amplitude we just need the phase difference between them at a particular location to determine whether the waves are in constructive interference or destructive interference.

Interference is a phenomenon in which there is superposition of two coherent waves at a particular location in the medium of propagation.

When the waves are in constructive interference then we get a resultant wave of maximum amplitude and vice-versa in case of destructive interference.

For constructive interference the waves must have either no phase difference or a phase difference of nλ, where n is any natural number.

For destructive interference the waves must have a phase difference of n×0.5λ, where n is any odd number.

The starter motor of a car engine draws a current of 140A from the battery. The copper wire to the motor runs for 0.90s until th

nasty-shy [4]

"1 Ampere" (A) means "1 coulomb of charge per second"

140 A means 140 coulombs per second

(140 coulomb/sec) x (0.9 sec) = 126 coulombs of charge.

Go a little farther:

Electrons are the things that move through wire carrying charge.

6.25 x 10¹⁸ electrons carry 1 coulomb of charge.

126 coulombs = 787,500,000,000,000,000,000 electrons (rounded)

In which of these situations, is mechanical energy being conserved? (Neglect, air resistance, friction, and breaking) Check all

Amiraneli [1.4K]

1) Mechanical energy is conserved in all the situations mentioned

2) True

3) Potential energy

4) The potential energy is 490 J

5) The potential energy is 750,000 J

Explanation:

1)

The mechanical energy of an object is the sum of its potential energy (PE) and its kinetic energy (KE):

$E=PE+KE$

When there are no conservative forces acting on the object (i.e. air resistance of friction), the mechanical energy is always conserved, so it is constant:

$E=const.$

This means that there is a continuous conversion between potential energy and kinetic energy.

In all the examples mentioned here, there are no air resistance or friction acting on the system: therefore, mechanical energy is conserved in all cases.

2)

The potential energy of the object falling to the ground is given by

$PE=mgh$

where

m is the mass

g is the acceleration of gravity

h is the height of the object above the ground

While the kinetic energy is given by

$KE=\frac{1}{2}mv^2$

where

v is the speed of the object

As the object falls, its height h decreases, while the speed v increases: therefore, the potential energy decreases and it is converted into kinetinc energy, which increases.

3)

The energy possessed by an object due to its position is called potential energy. It can be of two types:

- Gravitational potential energy: it is the energy possessed by an object due to its position in a gravitational field. It is given by

$PE=mgh$

where m is the mass, g the acceleration due to gravity, h the height of the object

- Elastic potential energy: it is the energy stored in an elastic object which is compressed or stretched - it is given by

$PE=\frac{1}{2}kx^2$

where k is the spring constant and x the elongation of the object relative to its equilibrium position.

4)

The (gravitational) potential energy stored in the block is calculated as

$PE=mgh$

where:

m = 10 kg is the mass of the block

$g=9.8 m/s^2$ is the acceleration due to gravity on Earth's surface

h = 5 m is the height of the object above the ground

Substituting, we find the potential energy:

$PE=(10)(9.8)(5)=490 J$

5)

The potential energy of the elevator is given by

$PE=mgh$

In this case, we have

h = 500 m (height of the elevator)

W = 1500 N (weight of the elevator)

We also know that the weight is the product of mass and acceleration due to gravity:

$W=mg$

So we can rewrite the first equation as

$PE=Wh$

And substituting, we find

$PE=(1500)(500)=750,000 J$

The temperature of a quantity of an ideal gas is a. one measure of its ability to transfer thermal energy to another body. b. pr

solong [7]

Answer:

d. correctly described by all the statements above.

Explanation:

Kinetic molecular theory of gases states that gas particles exhibit a perfectly elastic collision and are constantly in motion.

According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on temperature.

This ultimately implies that, the average kinetic energy of gas particles is directly proportional to the absolute temperature of an ideal gas. Thus, an increase in the average kinetic energy of gas particles would cause an increase in the absolute temperature of an ideal gas.

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Generally, the temperature of a quantity of an ideal gas is;

a. a measure of the ability of an ideal gas to transfer thermal energy to another body.

b. the average kinetic energy of gas particles is directly proportional to the absolute temperature of an ideal gas

c. proportional to the internal energy of the gas.
