A
method of procedure that has characterized natural science since the
17th century, consisting in systematic observation, measurement, and
experiment, and the formulation, testing, and modification of
hypotheses
Answer:
5 meters per second
Explanation:
5m is the distance
5m west is the vector
5m per second is the velocity
5m per second west is unknown
Answer:
W = 55.12 J
Explanation:
Given,
Natural length = 6 in
Force = 4 lb, stretched length = 8.4 in
We know,
F = k x
k is spring constant
4 = k (8.4-6)
k = 1.67 lb/in
Work done to stretch the spring to 10.1 in.
W = 55.12 J
Work done in stretching spring from 6 in to 10.1 in is equal to 55.12 J.
Answer:
The workdone is
Explanation:
From the question we are told that
The height of the cylinder is
The face Area is
The density of the cylinder is
Where is the density of freshwater which has a constant value
Now
Let the final height of the device under the water be
Let the initial volume underwater be
Let the initial height under water be
Let the final volume under water be
According to the rule of floatation
The weight of the cylinder = Upward thrust
This is mathematically represented as
So
=>
Now the work done is mathematically represented as
