The maximum efficiency is 10%

Explanation:

The maximum efficiency of a machine is given by:

$\eta=1-\frac{T_C}{T_H}$

where

$T_H$ is the temperature of the hot reservoir

$T_C$ is the temperature of the cold reservoir

For the machine in this problem, we have:

$T_H=400K$ is the temperature of the hot reservoir

$T_C=360K$ is the temperature of the cold reservoir

substituting, we find the max efficiency:

$\eta=1-\frac{360}{400}=0.1$

So, the efficiency is 0.10 (10%).

When a system is heated, heat is _______________ by the system. The amount of heat added is given a _______________ sign. When a

Valentin [98]

First of all, we need to write the First Law of thermodynamics assigning the correct sign convention:

$\Delta U = Q+W$

where

$\Delta U$ is the change in internal energy of the system

Q is the heat absorbed/released

W is the work done

and the signs are assigned based on whether there is an increase in the internal energy or not. Therefore:

Q is positive if it is absorbed by the system (because internal energy increases)

Q is negative if it is released by the system (because internal energy decreases)

W is negative if it is done by the system on the surrounding (because internal energy decreases)

W is positive if it is done by the surrounding on the system (because internal energy increases)

Using these definitions, we can now fill the text of the question:

When a system is heated, heat is ABSORBED by the system. The amount of heat added is given a POSITIVE sign. When a system is cooled, heat is RELEASED by the system. The amount of heat is given a NEGATIVE sign. If a gas expands, it must push the surrounding atmosphere away. Thus, work is done BY the system and is given a NEGATIVE sign. If a gas is compressed, then work is done ON the system. This work is given a POSITIVE sign.

Do we know which has more potential energy? object A or B? Best answer with reasoning gets brainliest.

babymother [125]

Answer:

Object C has the most potential energy.

Between A and B, we do not know which has more potential energy.

Explanation:

We know the object with the most potential energy and this is the object at C.

Potential energy is the energy due to the position of a body above the ground surface.

The higher a body is above ground, the more its potential energy.

Potential energy = mass x acceleration due to gravity x height

So;

Object C has the most potential energy.

Between A and B, we do not know which has more potential energy.

This is because, the height and mass of the objects are not quantified using numbers.

Potential energy is a function of mass and height and acceleration due to gravity but acceleration due gravity is a constant.

A positive charge traveling north enters a region where the electric field is uniform and points east. This charge will Group of

Bingel [31]

Option D is correct : This positive charge will veer east

It is given that the particle has a positive charge.

So, the direction of the force on the positive charge (and also the acceleration) is in the same direction as the electric field.

Now the electric field is uniform and points in east, the force on it $F=qE$ will also be pointed towards the east.

The positive charge was initially moving north, which means that the velocity vector was in the direction of north and when a positive charge first reaches an area with an electric field and force pointing east, its velocity vector will change to be along the electric field, or east.

That’s why a positive charge traveling north enters a region where the electric field is uniform and points east will veer east.
