Using v=u+at, Where v is final velocity(m/s), u is initial velocity(m/s), a is acceleration(m/s^2) and t is time(s).

v = 0 + 3.2*6
v=19.2 m/s.

What is the frequency of a wave if 10 waves go past in 1 second ?

KIM [24]

Answer:

f = 10 Hz

Explanation:

We need to find the frequency of a wave if 10 waves go past in 1 second. Total number of waves per unit time is called frequency. So,

$f=\dfrac{10}{1}=10\ Hz$

So, the frequency of a wave is 10 Hz.

Please help!!! The radius of a circle is 5.5 cm, the circumference in meters is 34.56, the area in square meters is 95.03. What

olga nikolaevna [1]

Answer:

47.515 cm²

In meter square= 4.7515 *10^-3 m²

Explanation:

The radius of a circle = 5.5 cm

In meter= 5.5*0.01

= 0.055 m

the circumference= 34.56 cm

in meters = 34.56 cm*0.01

= 0.3456 meters

the area= 95.03 cm²

in square meters =95.03*(0.01)²

in square meters= 9.503*10^-3 m²

. area under the curve at the right

= Area of semi circle

= Area of circle/2

= 95.03 /2

= 47.515 cm²

In meter square= 4.7515 *10^-3 m²
