Though corn does occur in alot of food it does not occur in coffee mostly comes from water and coffee beans
Answer:
A
A. Energy is lost when machines don't work right.
There are several information's already given in the question. Based on those given information's the answer can be easily deduced.
First angle of depression = 18°33'
= [18 + (33/60)] degree
= 18.55 degrees
Second angle of depression = 51°33'
= [51 + (33/60)] degrees
= 51.55 degrees
Height of the lighthouse = 200 feet
Then
Distance traveled by the boat from when it
was first noticed until it stopped = (200/tan 18.55) - (200/tan 51.55)
= (200/0.3356) - (200/1.2594)
= 594.95 - 158.81
= 436.14 feet
I hope the procedure is clear enough for you to understand.
The increase in gravitational potential energy for an object of mass m is given by
where
is the increase in altitude of the object.
In our problem, m=3.0 kg,
and
(approximated value), so we have
Answer:
1 Hz
Explanation:
For rope fixed on both ends the length corresponds to λ/2 (λ is wavelength)\
Thus L = λ/2
=> λ = 16 m
We know that frequency and wavelength are related as
f x λ = v where f is frequency and v is speed of the wave
thus f = v/λ
f = 16/16 =1 Hz
