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.

Two objects are dropped from different heights at the same instant. If the first object takes 10.7 seconds to hit the ground and
Lubov Fominskaja [6]

Answer:

The answer to your question is : 521.8 m

Explanation:

Data:

Different heights

Time first object (tfo) = 10.7 s

Time second object (tso)= 14.8 s

Initial speed of both objects(vo) = 0 m/s

a = 9.81 m/s²

Formula:

h = vot + 1/2 (a)(t)² but vo = 0    so, h = 1/2 (a)(t)²

Then, height fo      h = 1/2 (9.81)(10.7)² = 561.6 m

          height so     h = 1/2(9,81)(14.8)² = 1074.4 m

Difference in their heights =  1074.4 m - 561.6 m = 521.8 m
