Milimetres are before centimetres and centimetres are before metres
Answer:
Correct answer: Ep₁ = 105.11 J
Explanation:
if we take as the zero reference point the bottom of the hole then the height difference is 11 m. Let named h₁ = 11 m
The formula for calculating potential energy is:
E p = m g h => mg · 9.0 m = 86 J => mg = 86/9
when we substitute this into the next formula we get
m g h₁ = 86/9 · 11 = 105.11 J

Answer:
Time = 801.802 secs.
Explanation:
Speed can be defined as the rate of change in the magnitude of distance with respect to time. It is a scalar quantity because it only has magnitude but no direction.
Given the following data;
Average speed = 11.1m/s
Time =?
Distance = 8900m
Making time (t) the subject of formula, we have;
Time = 801.802 secs.
<em>Hence, the time the biker takes to cover the segment is 801.802 seconds. </em>
I am pretty sure it is called an interval between the 2 full Moons.
Answer:
gravitational force and outward pressure
Explanation:
The stars are very massive stellar objects, so they have a strong gravitational force, which drives the star to contract itself, but also in stars there are nuclear reactions such as fusion of hydrogen and other elements, that releases energy and creates a pressure from the center to the star exterior, an outward pressure that goes against the gravitational force. So when a star is stable these two forces exist in equilibrium or in balance, in which the star does not collapse by gravity or disintegrate by its outward pressure.
