Salmon often jump waterfalls to reach their breeding grounds. Starting downstream, 3.18 m away from a
waterfall 0.417 m in height, at what minimum
speed must a salmon jumping at an angle of
26.1◦ leave the water to continue upstream?
The acceleration due to gravity is 9.81 m/s2
.

In a good thermo flask the main cause of heat loss is

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
