- At pole the gravitation is more than that of equator .
And according to newtons second law
Force=Mass×Acceleration
And
- Hence force varies directly with acceleration hence weight will be more .
Answer:
answer is C
Explanation:
acceleration is rate of changing velocity in a time
Answer: heat energy, sound energy, and mechanical energy only
Explanation: I did the test in got it right.
Given that the arc length is:
s = ∫ √[1² + (dy/dx)²] dx
<span>So arc length between the two points is then: </span>
<span>s = 2*20sinh(x/20)
= 40sinh(x/20) </span>
<span>The straight distance between the two points is : d = 2x </span>
<span>So, x = d/2.
= 40/2
= 20 m </span>
<span>Plug this into the arc length equation to get:
s = 40sinh[20/20)]
=40* ½ (e - 1/e) </span>
<span> = 47 m</span>
To solve the problem, it is necessary to apply the concepts related to the diffraction given in circular spaces. By definition it is expressed as
Where,
\lambda = Wavelength
d = Optical Diameter
Angular resolution
In turn you can calculate the angle through the diameter and the arc length, that is,
Where,
x = The length of the arc
D = Distance
From known data we know that Jupiter's diameter is,
Replacing we have that,
Re-arrange to find d,
Therefore the minimum diameter of an optical telescope to resolve a Jupiter-sized planet is 0.968Km.
