For this time interval, find the x-component of the average velocity. express your answer using two significant figures.

you add equal amounts of heat to two identical cylinders containing equal amounts of the same ideal gas. cylinder a is allowed t

OleMash [197]

Temperature rise will be there in cylinder B more than in cylinder A because of internal energy.

what is internal energy?

The sum of the kinetic and chemical potential energies of all the particles in the system is the internal energy. Particles accelerate and pick up kinetic energy when energy is applied to increase the temperature.

Briefing:

Cylinder A uses the heat it absorbs to both work while expanding and to increase internal energy (or temperature).

While cylinder B solely uses the heat it absorbs to increase its internal energy

As a result, cylinder B's temperature rise is greater than cylinder A's.

Think Critically Suppose your teacher gave you a slide of an unknown cell. How would you tell whether the cell was from an anima

topjm [15]

Answer:

You will be able to tell whether the unknown cell is from an animal or from a plant through the knowledge of difference between plants and animal cells.

Explanation:

A cell can be defined as the simplest bit of living matter which exhibits a variety of shapes and sizes and that can exist independently.

When a slide of an unknown cell is studied under a microscope, different cell structures would be observed which would be used to conclude if the cell on the slide is a plant or animal cell.

The following features are observed in a plant cell:

--> cellulose cell wall is present

--> Chloroplast is present

--> A large central vacuole is present

--> Centriole is absent

The following features are observed in animal cell:

--> Cellulose cell wall is absent

--> Chloroplast is absent

--> Small vacuoles is present

--> Centriole is present

The difference between a plant and an animal cell can be seen from the features above and a clear knowledge of this will help the student tell whether the unknown cell is from an animal or from a plant.

Explanation:

Volume of 10 coins = 100ml - 75ml = 25ml

Volume of 1 coin = 25ml / 10 = 2.5ml

The average volume of each coin is 2.5ml.

While sitting in a swivel chair, you push against the floor with your heel to make the chair spin. The 6.7 N frictional force is

nexus9112 [7]

Answer:

I = 1.4kgm²

Explanation:

The rotational motion is caused by the frictional force, which generates a torque on the system. As there is no other force that creates a torque, this can be expressed in the equation of rotational motion below:

$\tau_f =I\alpha\\\\$

And $\tau_f=rf$ , where r is the distance from the point of application and the rotation axis, and f is the magnitude of the frictional force. This is because the frictional force is applied in the direction that causes the greatest angular acceleration (this is, 90°) and $rf\sin90\°=rf$ . Then, we have that:

$rf=I\alpha\\\\\implies I=\frac{rf}{\alpha}\\\\$

Plugging in the given values, we obtain:

$I=\frac{(0.39m)(6.7N)}{1.8rad/s^{2} } =1.4kgm^{2}$

In words, the total moment of inertia is equal to 1.4kgm².
