To solve this problem we will apply the concept of magnification, which is given as the relationship between the focal length of the eyepieces and the focal length of the objective. This relationship can be expressed mathematically as,
Here,
= Magnification
= Focal length eyepieces
= Focal length of the Objective
Rearranging to find the focal length of the objective
Replacing with our values
Therefore the focal length of th eobjective lenses is 27.75cm
Answer:
A
Explanation:
You have to give energy away for B. You have to think about that carefully. The CO2 starts out with a great deal of energy (mostly KE) and has to slow down to go from gas to a solid. Not B
In general C is the same way. Water has more energy than ice. Not C
Same principle in D. Not D.
So it's A
Answer:
an exhaust leak is most likely in your systems manifold or any of the joints along the exhaust system if the leak is the manifold not only will your engine volume increase. but some of them can be located and a running vehicle in the engine bay
Explanation:
lol hope it helps^^ I'm no expert but I'm just giving info
Answer: time; mass
Explanation:
The equation E=mc^2 shows that energy, e, and mass, m, are linked.
For objects moving in a straight line, the special theory of relativity applies to show that space and time are linked.
Answer:
y₀ = 1020.3 m
Explanation:
This is a projectile launching exercise, in this case as the package is released its initial vertical velocity is zero.
y = y₀ + t - ½ g t²
when it reaches the ground its height is zero
0 = y₀ + 0 - ½ g t²
y₀ = ½ g t²
let's calculate
y₀ = ½ 9.8 14.43²
y₀ = 1020.3 m
