Answer:
<em>In the observational method, the hypothesis is constructed to explain the observations. A simple one may be a generalization of the observations. A more complex hypothesis may postulate a relationship between the events, and may even be used to predict other observations.</em>
Answer:
Assume that
;
.
Density of the disk: approximately
.
Weight of the disk: approximately
.
Buoyant force on the disk if it is submerged under water: approximately
.
The disk will sink when placed in water.
Explanation:
Convert the dimensions of this disk to SI units:
- Diameter:
. - Thickness
.
The radius of a circle is 1/2 its diameter:
.
Volume of this disk:
.
Density of this disk:
.
indicates that the disk will sink when placed in water.
Weight of the object:
.
The buoyant force on an object in water is equal to the weight of water that this object displaces. When this disk is submerged under water, it will displace approximately
of water. The buoyant force on the disk will be:
.
The size of this disk's weight is greater than the size of the buoyant force on it when submerged under water. As a result, the disk will sink when placed in water.
The resistance of the laser whose voltage difference pushes the current through its laser diode is 2 ohms.
<h3>What is resistance?</h3>
The resistance is the opposition offered to the current flow.
According to the ohm's law, potential difference is directly proportional to the current flowing in the conductor.
V =I x R
Where R is the constant of proportionality called resistance.
Given is the potential difference V =10 Volts and the current flow of 5A, then the resistance will be
R = 10/5 = 2 ohms.
Thus, the resistance of the laser is 2 ohms.

The independent variable is how steep the slope is
what ever force the wave hit it at (on the x-axis) would create another wave from the force of the first wave. though the wave would be smaller because of other forces
