Answer: 44.89 times
Explanation:
Given that the earth's average velocity is about 6.7 times faster than that of planetoid Makemake
Given that the formula involved is:
R2/R1 = (V1/V2)^2
Let V1 = earth velocity and R1 = earth orbital distance
While R2 = Makemake velocity and R2 = orbital distance.
Since the earth's average velocity is about 6.7 times faster than that of planetoid Makemake, then,
V1/V2 = 6.7
Substitute this in the formula above
R2/R1 = (6.7)^2
R2/R1 = 44.89
Cross multiply
R2 = 44.89R1
Therefore, Makemake's orbit is about 44.89 times larger than the earth's orbit.
The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
Answer:
0.11m
Explanation:
let's assume the boat is of uniform construction
Ignoring friction losses
Also assume the origin is at the end of the boat originally with the heavier person
the center of mass of the whole system will not change relative to the water when the two swap ends
Originally, the center of mass is
85[0] + 90[3.5/2] + 50[3.5] / (85 + 90 + 50) = 1.14m from the origin
after the swap, the center of mass is
50[0] + 90[3.5/2] + 85[3.5] / (85 + 90+ 50) = 1.030m from the origin
The center of mass has shifted
1.14-1.030 = 0.11m
as no external force acted on the system, the center of mass relative to the water will not change. The boat will therefore shift towards the end where the heavier person originally sat
;Net force = mass of the body × acceleration of the body due to the net force
; 5000 = 2500 a...then divide both sides by 2500
; acceleration(a) = 2 m/s^2
Density reduces
Explanation:
The density of a fluid will reduce as a substance gains more thermal energy. Heat is a form of thermal energy usually noticed as temperature differences in a matter.
- When thermal energy is gained by a body, the temperature of the body rises.
- The particles of the medium gains more kinetic energy.
- This causes the substance to expand and it has more volume.
- When a substance expands, it occupies more space.
- The more the volume a body occupies, the lesser the density.
- Expansion does not change the mass of the fluid but the volume changes.
- This is why density decreases.
