Answer: a, c, and g
Explanation:
Buoyant Force is an upward force acting on submerged object equal to weight of fluid displaced by the submerged object.
If no part is submerged (V = 0) that is volume. Therefore there is Zero Buoyant Force.
Fully submerged produces greatest buoyant force since greatest amount of fluid was displaced.
Whenever it is fully submerged it will have the greatest buoyant force.
Buoyant Force DOES NOT Depend on Depth
A fully submerged object displaces its volume in fluid
A floating object displaces its weight in fluid.
The centripetal force : F = 293.3125 N
<h3>Further explanation</h3>
Given
mass = 65 kg
v = 9.5 m/s
r = 20 m
Required
the centripetal force
Solution
Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle
F = centripetal force, N
m = mass, Kg
v = linear velocity, m / s
r = radius, m
Input the value :
F = 65 x 9.5² / 20
F = 293.3125 N
The correct answer is
<span>c) very small and very large
Let's see this with a few examples:
1) if we have a very small number, such as
</span>
<span>we see that we can write it easily by using the scientific notation:
</span>
<span>2) Similarly, if we have a very large number:
</span>
<span>we see that we can write it easily by using again the scientific notation:
</span>
