Answer:

7. 1.56

8. A curved line that slopes upward

Explanation:

7. The curve for quartz at the left side of the graph (400 nm) is just above the middle of the distance between 1.5 and 1.6, so is best approximated by 1.56.

___

8. The graph shows n vs. wavelength. The question asks about n vs. frequency. Frequency is inversely proportional to wavelengh, which means you need to describe the curve from right to left, rather than left to right. From right to left, the curve rises, so can be called "a curved line that slopes upward."

WheN a car is driven some distance the air pressure in the tyre increases,why?
KatRina [158]
Over the course of a long drive, as a result of alternating between braking and acceleration and of course steering, tires get heated up. When this happens, the air within the tires gets heated up, causing the air within the tire to expand. This expanding air exerts force on the tire from inside thus increasing tire pressure.

What force in Newton is required to accelerate a car starting from rest to 20 m/s in 15 seconds if the mass of the car is 2500 k
Lyrx [107]

We will solve this question using the second law of motion which states that force is directly equal to the product of mass and acceleration.

\sf \: F=ma

Where,

  • F is force
  • m is mass
  • a is acceleration

In our case,

  • F = ?
  • m = 2500 kg
  • a = 20m/s

\tt \: F_{net}  = 2500 \times 20 \\   \tt= 50000

<em>Thus, The force of 50000 Newton is required to accelerate a car of 2500 kg...~</em>
