Answer:
The least number of forces required to stretch a spring is one.
Explanation:
Let suppose that spring is ideal, that is, that effects from its mass can be neglected since it is insignificant in comparison with external forces. In addition, let the spring have a linear behavior, meaning that net external longitudinal force exerted on spring is directly proportional to defomation. (Hooke's Law) That is:
(1)
(2)
Where:
- Net external force, measured in newtons.
- Spring constant, measured in newtons per meter.
- Deformation of spring, measured in meters.
Hence, the least number of forces required to stretch a spring is one.
Answer:
Explanation:
Altitude of the Sun and the latitude position on the earth play an important role in the season change on the earth.
When the altitude of the sun is high then the average temperature of the earth is higher because the luminous intensity of the sun rays is higher due to the focusing of high energy sun rays over a small area.
But when the sun is at higher altitudes we receive less denser rays of the sun and hence we have less heat on the earth on an average.
- But despite of the altitude some places on the earth have distinct temperature than the other place at the same time of the year. This is due to their latitudinal location. The places near the equator are warmer most of the times throughout the year because they receive the most direct rays while the poles receive slanting rays and hence are colder even in summer when the earth is at lower altitudes.
For a myelinated nerve fiber has a conduction speed of 53 m/s, the capacitance of each segment is mathematically given as
C=8.2*10^{-13}F
<h3>What is the capacitance of each segment?</h3>
Generally, the equation for the Constant is mathematically given as
t=RC
Therefore
t=V/d
Hence
C=V/Rd
C=1.2*1)^-3/26*10^6*56
C=8.2*10^{-13}
In conclusion, the capacitance
C=8.2*10^{-13}F
