Wind Energy is the kind of energy will Cassie uses to power the boat.
What is wind energy?
The method of producing electricity using air or wind currents that naturally occur in the earth's atmosphere is known as wind energy (or wind power). Electricity is produced by modern wind turbines that harness the kinetic energy of the wind. Wind passing across the turbine's blades is the initial step.
What is the major problem with wind energy?
Wind energy has the potential to have negative environmental effects, including the possibility of reducing, fragmenting, or deteriorating habitat for wildlife, fish, and plants, as with all energy supply choices. Furthermore, flying animals like birds and bats may be harmed by turbine blades in operation.

Answer:
minimum two photogate
Explanation:
The photogate allows us to activate the measurement of time, so we must place at least two of them, one at the beginning of the movement to measure the initial time and another at the end of the movement to measure the final time, of course we must have measured the distance. This gives us the average speed between the two photocells
For measurements with more changes curves, slopes, one photogate must be placed at the beginning of the curve or slope and another at the end.
Answer:
move the point of the fulcrum
Explanation:
you can do this by moving yourself closer to the pivot point, or moving the sea saw so that your sister has more of the board on her side
Transmits i think sorry hope i helped
Answer:
Work done, W = 141174 Joules
Explanation:
It is given that,
Constant tension acting on the boat, T = F = 465 N
Speed of the boat, v = 4.6 m/s
Time, t = 1.1 min = 66 seconds
Let W is the work done by the tension. It is equal to the product of force and displacement. It is given by :
Since,
W = 141174 Joules
So, the work is done by the tension is 141174 Joules. Hence, this is the required solution.
