This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.
Answer:
3.3 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
The fish needs to see the pelican before 0.2 seconds in order to escape so the time pelican has is 1.81-0.2=1.61 seconds
In that time the pelican would have traveled
So, the pelican would be 16-12.71 = 3.3 m above the water.
Answer:
m = image distance/object distance
m=35/15=7/3
f=uv/(u+v)
35*15/(35+15)
f=10.5cm
Hello! I don't know if this will help you any but I worked it out, got nothing on it. So, I just had my twin help me and he had nothing either. But, this is just how to find the transformation. Seems like this is already complete to me.
To find the transformation, compare the equation to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Parent function : y=√a
Horizontal shift : None
Vertical shift : none
Reflection about the x-axis : none
Vertical stretch : Stretched.
I am so sorry if this doesn't help you but to me, in both my eyes and my brother's eyes, this already looks complete. I hope this helps you out. Again, so sorry if it doesn't.
