An elastic collision<span> is where there is no loss of kinetic energy in the </span>collision<span>. Momentum is conserved saved in </span>inelastic collisions<span>, but cannot track the kinetic energy through the </span>collision<span> since some of it is changed into other forms of energy.</span>
Answer:
By the use of slow motion camera.
Explanation:
Visually, it is very hard to differentiate between an ac and dc power supply. But Since, we that In Ac supply polarity changes 100 times in a second ( because frequency of ac supply is 50 Hz generally). Whereas, Dc gives a steady power supply. So, in slow motion camera we can easily capture the flickering light tubes which won't happen in case of dc supply.
Answer:
0.079 m or 79 mm
Explanation:
Using the equation of motion
v = √(2as)
Where v is the velocity
a is acceleration = 1400m/s²
s is the distance = 0.55 mm = 0.00055m
Therefore
= √(2 × 1400m/s² × 0.00055 m) = 1.54 m/s
Therefore; initial velocity = 1.54 m/s
Then we use the equation of motion s = v² / 2g
Take g = 9.8 m/s²
Therefore
= (1.54m/s)² / 19.6 m/s²
= 0.079 m or 79 mm
Answer:
Planetary seasons are caused by two factors:
1. axial tilt and
2. variable distance from the sun
Explanation:
Earth's orbit is nearly circular and so has little effect on climate. It's our planet's axial tilt that causes almost all seasonal changes.
