I believe the answer is a. Because the formula of kinetic energy is 1/2(m)•(v^2)
A). Kepler's first law of planetary motion ... "Each planet moves
in an elliptical orbit, with the Sun at one focus of the ellipse."
B). Heliocentric motion ... motion in an orbit around the Sun.
C). Eccentricity ... what makes an ellipse different from a circle.
The eccentricity of a circle is zero.
The eccentricity of the Earth's orbit is very small.
The eccentricity of a comet's orbit is big.
D). Retrograde motion ... the apparent, temporary, backward
motion of a planet on its path through the stars.
Answer: if the door knob is metal the static electricity will exit your body, but shock you in the process
Explanation:
Answer:
The deformation in the pole due to force is 0.70 mm.
Explanation:
Given that,
Height = 20.0 m
Diameter = 4.00 cm
Force = 1100 N
We need to calculate the area
Using formula of area
We need to calculate the deformation
Using formula of deformation
Where, s = shear modulus
F = force
l = length
A = area
Put the value into the formula
Hence, The deformation in the pole due to force is 0.70 mm.
