Answer:
The required amplitud is 0.11cm
Explanation:
To solve this problem it is necessary to apply the concepts related to simple harmonic motion, where displacement is given by
Where,
A = Amplitude
f = Frequency
t = time
If we derivate the expression we can obtain the Acceleration, there
x would be A for the minimum amplite of vibration, then
Replacing with out values,
Therefore the required amplitud is 0.1146cm
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
Answer:
Yes, extrapolated value do agree with accepted value of free-fall acceleration
Explanation:
Extrapolated value of acceleration up to 90 degree is accepted. There is an existing equation relating the acceleration of a body moving down a frictionless incline plane and the angle of inclination.
acceleration of the object is proportional to sine of the angle of inclination and the acceleration due to gravity. a=gsin(θ)
The value can be derived by calculating the acceleration at different angle of inclination and comparing the trend.
A dish shaped large muscle which moves up and down when there is contraction and expansion of lungs is the diaphragm which is present between the chest cavity and lower abdominal region. The action of the diaphragm is affected by an inflammation occurring below the muscular disc which will affect the process of breathing. The forceful breathing may result in strain and stress in the back muscles of the human body. This in turn causes pain in the shoulder.
