Whoa ! Wait a second. The weight of the displaced water
is ALWAYS equal to the buoyant force.
In the case of a floating object ... whether it's an iceberg or
a dead fly ... the part that's under the surface is the part that's
displacing water.
<span>a. less biomass
b. more biomass
c. more broad-leaf trees
d. locations near the equator
i would say c

Answer:
112.17 m/s
56.427 years
Explanation:
h = 3.18 x 10^10 m
R = 6.4 x 10^6 m
r = R + h = 3.18064 x 10^10 m
M = 6 x 10^24 kg
The formula for the orbital velocity is given by
v = 112.17 m/s
Orbital period, T = 2 x 3.14 x 3.18064 x 10^10 / 112.17
T = 0.178 x 10^10 s
T = 56.427 years
Answer:
see explanation
Explanation:
You are missing the chart with the rates and time to do this, however, I wll do it with a similar exercise here, and you only need to replace the procedure with your data:
See the attached table.
From the left we have:
r = 1/2 (50 + 48 + 46 + 44 + 42 + 40) = 135 L/min
From the right we have:
r = 1/2 (48 + 46 +44 + 42 + 40 + 38) = 129 L/min.
And this should be the correct answer. Watch your chart and replace if it's neccesary.
Considering the definition of kinetic energy, the bullet has a kinetic energy of 156.25 J.
<h3>Kinetic energy</h3>
Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and in a rest position, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its rest state by applying a force to it.
The kinetic energy is represented by the following expression:
Ec= ½ mv²
Where:
- Ec is the kinetic energy, which is measured in Joules (J).
- m is the mass measured in kilograms (kg).
- v is the speed measured in meters over seconds (m/s).
<h3>Kinetic energy of a bullet</h3>
In this case, you know:
Replacing in the definition of kinetic energy:
Ec= ½ ×0.500 kg× (25 m/s)²
Solving:
<u><em>Ec= 156.25 J</em></u>
Finally, the bullet has a kinetic energy of 156.25 J.
