Answer:

The net displacement of the car is 3 km West

Explanation:

Please see the attached drawing to understand the car's trajectory: First in the East direction for 4 km (indicated by the green arrow that starts at the origin (zero), and stops at position 4 on the right (East).

Then from that position, it moves back towards the West going over its initial path, it goes through the origin and continues for 3 more km completing a moving to the West a total of 7 km. This is indicated in the drawing with an orange trace that end in position 3 to the left (West) of zero.

So, its NET displacement considered from the point of departure (origin at zero) to the final point where the trip ended, is 3 km to the west.

The net displacement of the car from the initial point will be 3 kilometer west.

<u>Explanation:</u>

Displacement is the shortest distance between two points, whereas the distance is the total distance between two points.

Displacement is a vector quantity and distance is scalar quantity. Let the car starts from point A and reaches point B in the East direction, i.e., 4 km.

Now from point B it starts moving west and reaches point C beyond point A, i.e., 7 km.  

                                                A---------------------.>B    4KM

                    C <--------------------------------------------B     7KM

finally the resultant distance is 3 km west

A hot copper pan is dropped into at tub of hot water. If the water's temperature rises, what happens to the temperature of the p
choli [55]

Explanation:

As it is given that hot pan of copper is dropped into a tub of hot water and the temperature of water rises. This means that heat from the pan has been released and this heat is gained by water.

As a result, temperature of copper pan has decreased and this decrease will continue till the time temperature of both copper pan and water will reach the same temperature.

As thermal energy is defined as the energy in which when two objects come in physical contact with each other then no exchange of heat energy will take place.

Thus, we can conclude that when temperature of both copper pan and water will be equal then it means that both of them has reached thermal equilibrium.

A street light is mounted at the top of a 15-ft-tall pole. A man 6 ft tall walks away from the pole with a speed of 4 ft/s along
babymother [125]

Answer:

Explanation:

height of pole = 15 ft

height of man = 6 ft

Let the length of shadow is y .

According to the diagram

Let at any time the distance of man is x.

The two triangles are similar

\frac{y-x}{y}=\frac{6}{15}

15 y - 15 x = 6 y

9 y = 15 x

y=\frac{5}{3}x

Differentiate with respect to time.

\frac{dy}{dt}=\frac{5}{3}\frac{dx}{dt}

As given, dx/dt = 4 ft/s

\frac{dy}{dt}=\frac{5}{3}\times 4

\frac{dy}{dt}=\frac{20}{3} ft/s
