shtirl [24]

Answer: The correct answer is option (D).

Explanation:

The area under the line is 10 meters that is displacement which means that area enclosed by the right angled triangle is 10 unit squares.

So, the it can be written as:

\text{area of triangle}=\frac{1}{2}\times velocity\times time

10=\frac{1}{2}\times 2.0 m/s\times time

time =10 seconds

Hence the, the correct answer is option (D).

disa [49]

Answer:

Correct option : (c) period.                        

Explanation:

The time that is required for a vibrating object to complete one full cycle is called the time period. If f is the frequency of a wave, then the relation between the frequency and the time period is given by :

T=\dfrac{1}{f}

These are the characteristics of a wave. Some other characteristics are wavelength, amplitude, intensity etc. So, the correct option is (c) "period".
