Answer:
Variance is
Solution:
As per the question:
Average value of the steam, = 25000 pounds per hour,
To calculate the variance, of the steam:
where
= standard deviation
at 0.8 is 1.285 from Z-table
Thus
Variance,
Answer:
Explanation:
Stars form inside relatively dense concentrations of interstellar gas and dust known as molecular clouds. The deep cold also causes the gas to cluster to high densities. When the density reaches a certain degree, stars form. Since the regions are dense, they become opaque to visible light and are known as dark nebula.
Answer:
Distance : 0.06533 meters or 65.33 mm
Explanation:
To solve this problem we can make the forces equal when the system is at equilibrium.
mass gravity ( constant ) = spring constant
where l = the length at which the rubber band is stretched
0.2 kg 9.8 m / s² = 30 N/m
1.96 kg m / s² = 30 N/m
l = 1.96 kg m / s² / 30 N/m = 0.06533 meters / 65.33 mm
The rubber band is stretched a distance of 0.06533 meters, or 65.33 mm.
To solve the problem it is necessary to apply the concept of Load on capacitors. The charge Q on the plates is proportional to the potential difference V across the two plates.
It can be mathematically defined as:
Q= CV
Where,
C = Capacitance
V = Voltage
Our values are given as,
Substituting values in the above formula, we get
Where
Therefore the charge must be 18pC to create a 30V Poential difference.
Hello,
Here is your answer:
The proper answer to this question is that you find the velocity by "you have to divide the distance by time of the object".
