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:
D. An image that is smaller than the object and is behind the mirror
Answer:
34000 J or 34 kJ
Explanation:
From the question, The energy needed to just melt the ice cube does not requires any external temperature or change in temperature, Hence it is called latent heat
By Applying,
Q' = C'm........................ Equation 1
Where Q' = Latent heat, C' = Specific latent heat of fusion of water, m = mass of ice.
Given: C' = 340000 J/kg, m = 100 g = 0.1 kg
Substitute into equation 1
Q' = 0.1(340000)
Q' = 34000 J
Q' = 34 kJ
the change needed to break down a compound is chemical change
