Answer:
8
Explanation:
Applying,
v = λf................ Equation 1
Where v = velocity/ speed of the wave, λ = wave length of the wave, f = number of waves the person surf in one seconds.
make f the subject of the equation
f = v/λ............ Equation 2
From the question,
Given: v = 1.6 m/s, λ = 24 m
Substitute these values into equation 2
f = 1.6/24
f = 0.0667 wave/seconds.
If,
in one seconds, the person surf a total wave crest of 0.0667
Therefore,
in one hours, he will surf a total wave crest of (0.0667×60×60) = 240 waves crest
He rides for every 30th wave crest,
Hence,
number of wave crest the person surf in one hour = 240/30 = 8
Answer:
the answer is d
Explanation:
the more mass there is, the larger the gravitational pull is.
Energy keeps our school running properly. Without energy computers, smart-boards, printers, and our lights would not work.
The world runs on energy.
Answer:
1800 m
Explanation:
This question requires you to calculate the distance traveled after 6 minutes at a speed of 5m/s
Given speed as 5m/s and time is 6 minutes then;
Change minutes to seconds by multiplying the minutes by 60 seconds
1 minute=60 seconds
6 minutes= 6*60 = 360 seconds
Apply the formula for speed where;
S=D/T where S is speed, D is distance and T is time
To get D , rewrite formula as S*T
where S= 5m/s and T=360s
D= 5*360 =1800m
Answer:
The answer is B, although technically that is an eclipse.
