Potential energy. Kinetic energy is movment
Answer:
Option 2. √3 x V
Explanation:
Let the velocity of satellite orbiting Earth at r be V
Let the velocity of the satellite orbiting at 3r be V1
V (orbiting at r) = √(2gr)
V1 (orbiting at 3r) = √(2g3r)
Now let us find the ratio of V1(orbiting at 3r) to V(orbiting at r) .
This is illustrated below
V1 / V = √(2g3r)/√(2gr)
V1 / V = √3
Cross multiply to express in linear form
V1 = V x√3
V1 = √3 x V
From the above illustrations, we can see that the velocity of the satellite when it is moved to an orbital radius of 3r is: √3 x V
Astrophysics is a term used to describe knowledge about the universe.
Answer:
θ = 3.19 arc second
Explanation:
The resolution of a telescope is given by the rayleigh criterion, which establishes that two objects are separated if the principal maximum of diffraction of one of them coincides with the first minimum of diffraction of the second object, based on this the solution is given by the first diffraction minimum, the a slit is
a sin θ = m λ
with m = 1
in the case of circular apertures the equation must be found in polar coordinates, therefore a numerical constant is introduced
a sin θ = 1.22 λ
Angles are measured in radians and in these experiments they are small
sin θ = θ
θ= 1.22 λ / a
in this case a = 6.09 in, the wavelength is wrong = 550 10⁻⁹ m which is the maximum resolution of the human eye
l
et's reduce the magnitudes to the SI system
d = 6.09‘ 2.54 10⁻-2 m / 1 inch = 15.4686 10-2 m
let's calculate
θ = 1.22 550 10-9 / 15.468 10-2
θ = 15.5 10⁻⁶ rad
rad = 2.06 105 s
θ = 15.5 10⁻⁶ rad 2.06 105s/ 1 rad
θ = 3.19 s
Answer:
Explanation:
Input refers to the amount of energy put into a device, and output refers to the amount of energy that comes out. A device may change the type of energy but not the amount. For example, a light bulb's input energy is the form of electrical energy, and its output energy is in the form of light and heat. Efficiency.
