During either one, the sun, moon, and Earth are lined up in the same straight line. The difference is whether the moon or the Earth is the one in the "middle".
Impulse is change in momentum. The initial momentum was
0.1kg*11m/s=1.1kg m/s.
The second momentum is 0.1*(-8.8m/s)=-0.88 (since it's moving backward now)
The difference is P1-P2 = 1.1-(-0.88)=1.98kg m/s
Given,
pH of bleach = 12
pH of detergent= 8 to 10
pH of eye drops = 7
pH of lemon juice 1 to 3
pH of tea = 4 to 6
On rearranging samples from most acidic to most basic,
1. Lemon juics
2. Tea
3. eye drops
4. detergent
5. Bleach
Incandescent lights get hot very quickly and therefore can easily burn u or catch fire
Using the metric units kilometer (km) and meter (m), as seen in the picture of the ladder method example. So, the answer would be 14km = 14000m
