hope this helps
Answer: The control group is the part where you see what happens when you change a variable you want to study/examine. Basically, you need the control group because you need something to see what happens when you change something.
Hope this Helps! :))))
Resistance = (voltage) / (current)
Resistance = (12v) / (0.33 A)
Resistance = (12/0.33) ohms
<em>Resistance = 36.4 ohms</em>
According to the conservation of energy
- Potential energy at any given instance is equal to the Kinetic energy as energy can neither be created nor be destroyed
Mass is 2kg=m
#A
h=5m
PE
Now
- KE=98J
- 1/2mv²=98J
- 1/2×2v²=98J
- v²=98J
- v=√98
- v=9.4m/s
#B
h=3.2m
PE:-
Now
- KE=62.7J
- 1/2mv²=62.7
- v²=62.7
- v=√62.7
- v=7.9m/s
#C
h=2m
PE
Now
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.
