Answer: Yes.
Explanation:
There is gravity in water because How does the water go up in the cycle? the garavity with the wind pull it up.
Answer:
Energy is stored in the bonds between atoms
Answer:
option C
Explanation:
The correct answer is option C
When the ray of light pass from higher refractive index to lower refractive index then the light bend away from the normal.
when the refracted ray is parallel to the boundary of the medium, θ₂ = 90°
and the incident angle θ₁
so, the angle θc is known as the critical angle.
At critical angle the refracted ray becomes parallel to boundary surface.
Answer:
Fatty acids.
Explanation:
-Long term energy storage is stored in the form of triglycerides .
-They are efficient storing molecules. They are more efficient thatn glycogen(cabohydrates).
-Fatty acids are more calori dense hence them being ideal for long term energy storage.
1. Ideal Mechanical Advantage (IMA): 9
Explanation:
For a wheel and axle system like the steering wheel, the IMA is given by:
where
is the radius of the wheel
is the radius of the axle
For the steering wheel of the problem, we see that 
and 
, so the IMA is
2. Efficiency: 88.9%
Explanation:
The efficiency of a system is defined as the ratio between the AMA (actual mechanical advantage) and the IMA:
In this problem, AMA=8 and IMA=9, so the efficiency is
