Because the Earth rotates through two tidal<span> “bulges” every lunar day, coastal areas experience<em> two </em></span><em>high</em><span><em> and two low </em></span><em>tides</em><span><em> every 24 hours and 50 minutes</em>.
</span>High tides occur<span> 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from </span>high<span> to low, or from low to </span>high<span>.
I hope this helped!! Have an amazing day :))</span>
Answer:
Explanation:
1 Joule () is equivalent to . So, we have to make the conversion:
Joules KiloJoules

Дано:
S1 = 50 км
t1 = 4 часа
S2 = 100 км
t2 = 1 час
Найти:
Vср - ?
Решение:
Vср = S/t
Sср = S1 + S2 = 50 + 100 = 150 км
tср = t1 + t2 = 4 + 1 = 5 часов
Vcр = 150/5 = 30 км/ч
Ответ:
30 км/ч
Answer:
Work done = 838470 Joules.
Explanation:
Given the following data;
Power = 19 hp
Time = 1 minute to seconds = 60 seconds.
Next, we would convert the unit of power in "hp" to "Watt."
1 Watt = 0.00135962 horsepower
x Watt = 19 horsepower
Cross-multiplying, we have;
19 = 0.00135962x
x = 19/0.00135962
x = 13974.5 Watts.
Now, to find the work done in moving the mower;
Work done = power * time
Substituting into the formula, we have;
Work done = 13974.5 * 60
Work done = 838470 Joules.
