Health psychology focuses on how biological, social and psychological factors influence health and illness. Health psychologists study how patients handle illness, why some people don't follow medical advice and the most effective ways to control pain or change poor health habits.
We must use two formulas of energy first how energy is related to wavelength:
Such that , c is the speed of light in a vacuum and h is Plank's constant.
And the second equation is how energy relates to voltage:
Such that q is the charge of the particle (in this case the electron) and V is voltage. By substituting the second equation into the first we have:
We know that:
And so:
Mass is an internal characteristics of a body (or a particle). Under any circumstances it remains the same.
The value of weight, however, depends on the strength of gravitational force.
Answer:
Maximum Tension=224N
Minimum tension= 64N
Explanation:
Given
mass =8 kg
constant speed = 6m/s .
g=10m/s^2
Maximum Tension= [(mv^2/ r) + (mg)]
Minimum tension= [(mv^2/ r) - (mg)]
Then substitute the values,
Maximum Tension= [8 × 6^2)/2 +(8×9.8)] = 224N
Minimum tension= [8 × 6^2)/2 -(8×9.8)]
=64N
Hence, Minimum tension and maximum Tension are =64N and 2224N respectively
