Newton told him the orbits must have ellipses. Let me know if this helps.
Answer:
Work is defined as the process of energy transfer to the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule.
Explanation:
Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt. One watt is equal to one joule per second. Power is a scalar quantity.
Answer:
I = 0.25 [amp]
Explanation:
To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the current by the resistance.
V = I*R
where:
V = voltage [Volt]
I = amperage or current [amp]
R = resistance [ohm]
Since all resistors are connected in series, the total resistance will be equal to the arithmetic sum of all resistors.
Rt = 2 + 8 + 14
Rt = 24 [ohm]
Now clearing I for amperage
I = V/Rt
I = 6/24
I = 0.25 [amp]
12.5 = 100 * (1/2)^n
divide by 100:
0.125 = (0.5)^n
this is equivalent to:
, which equals 3.
(since 0.5 cubed = 0.125)
Answer:
* Temperature changes
* Changes in the tension
* Errors in the meter marks
Explanation:
When we are using several meters to make a measurement we have several aspects that can cause the readings to differ.
* Temperature changes make the dilation between readings different, at higher temperatures the material of the meter expands and the reading decreases.
* Changes in the tension with which the meter is pulled to keep it straight, in general all materials bend under the action of gravity, so you have to pull them to make them straight, if the forces are different from the material is lengthened decide Young's modulus, inducing different readings
* Errors in the meter marks, especially in the initial part that is covered by a hook, different positions of the hook change the readings.
* Structural problems, such as rust, bends that create changes in the length of the meter material.
