Question

Note down the maximum temperature of first seven days of November 2021 and represent the data using Line Graph.​

Answer 1

Answer:-

A bell works with the principle of working of electromagnetism.

When the switch is pushed on, the circuit gets completed and the current starts flowing through the U-shaped electromagnet which creates a magnetic field in the core. This attracts the iron armature.

When the armature moves towards the electromagnet, the hammer strikes the gong and the bell rings.

As the armature moves towards the electromagnet, the contact with the adjustment screw breaks which breaks the closed circuit and stops the current. Now, when there is no current there is no electromagnetism and the armature returns to the original position. This making and breaking of the circuit of the electromagnet continue as long as the button remains pressed.Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism.

Answer 2

Answer:

We have two graphs actual and forecast, In the graph x−axis represents days and y−axis represents the temperature

Scale :

On x−axis 4 cm =1 day

On y−axis 2 cm =5° C

To find the temperature at particular day:

Trace the vertical line parallel to y−axis passing from the point on x−axis, find the point where this vertical line intersects the graph.

Now from that point trace a horizontal line parallel to x−axis, this line intersects the y−axis at required point.

To find the day at particular temperature:

Trace the horizontal line parallel to x−axis passing from the temperature point on y−axis, find the point where this horizontal line intersects the graph.

Now from that point trace a vertical line parallel to y−axis, this line intersects the x−axis at required point.

Now,

a) Forecast temperature and actual temperature are same where the graphs of both intersects which is Tuesday, Friday and Sunday

b) Follow step 1 to find temperature for graph forecast on days of week,

Mon −15° C

Tue −20°C

Wed −25° C

Thu −22.5°C

Fri −15°C

Sat −30° C

Sun −35° C

So, maximum forecast temperature during the week is 35°C
