Answer:

2,500 Joules (J) or Newton Meter (N M)

Explanation:

Work = Force x Distance

The force in this equation is 500 Newtons. The distance (displacement) is 5 meters. Plug it into the equation above.

Work = 5m x 500n

Work = 2,500 Joules or Newton-Meters.

Therefore 2,500 Joules or Newton Meters of work is done on an object.

Which of the following statements is true for real gases?

jok3333 [9.3K]

Answer:

A. The volume occupied by the molecules can cause an increase in pressure compared to the ideal gas.

D. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures.

Explanation:

as we know by real gas equation

$(P + \frac{an^2}{V^2})(V - nb) = nRT$

while ideal gas equation is given as

$PV = nRT$

so from above formula we can say that net pressure is increased in real gas

Also we know that all real gas will close to behave like ideal gas when the pressure of the real gas is low and temperature of the gas is high

So above are the correct observations

The driver of a car traveling at a speed of 25.5 m/s slams on the brakes and comes to a stop in 3.4 s. If we assume that the car

marusya05 [52]

Answer:

(a). The average speed of the car is 12.75 m/s

(b). The distance is 43.35 m.

Explanation:

Given that,

Initial speed = -25.5 m/s

Final speed = 0

Time = 3.4 s

(a). We need to calculate the average speed

Using formula of average speed

$v_{avg}=\dfrac{v_{f}-v_{i}}{2}$

Put the value into the formula

$v_{avg}=\dfrac{0-(-25.5)}{2}$

$v_{avg}=12.75\ m/s$

(b). We need to calculate the acceleration

Using equation of motion

$v_{f}=v_{i}+at$

$a =\dfrac{v_{f}-v_{i}}{t}$

$a=\dfrac{-25.5-0}{3.4}$

$a=-7.5\ m/s^2$

We need to calculate the distance

Using equation of motion

$s = ut+\dfrac{1}{2}at^2$

$s=25.5\times3.4+\dfrac{1}{2}\times(-7.5)\times(3.4)^2$

$s=43.35\ m$

Hence, (a). The average speed of the car is 12.75 m/s

(b). The distance is 43.35 m.

Which of the following statements accurately describes a series circuit? Select all that apply. The flow of electrons follow the

hammer [34]

In series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits.

And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.

Option A and D

<u>Explanation:</u>

A circuit consists of number of passive and active devices in it. And depending upon the connections between the passive devices, the flow of current and potential drop across them will be specified.

Like if the passive devices are connected parallel to each other, the current flow through each device will vary but the voltage drop will be same. Similarly, if the passive devices are connected in series, then the current flow will be constant in the devices but the potential drop will vary.

Thus, in series connections, the flow of electrons follow the same path as the current remains constant in all the elements of the circuits. And the total resistance of the circuit increases as more resistors are added to the circuit in serial manner.
