Answer:
The average speed of the oil is 1 m/s.
Explanation:
Given that,
Viscosity 
Radius r = 3.0 mm
Length = 1.0 m
Pressure = 200 kPa
We need to calculate the average speed of the oil
Using formula of pressure


Where, A = area
= density of oil
= viscosity
Put the value into the formula


Hence, The average speed of the oil is 1 m/s.

<span>The correct answer is option B. i.e UV Rays. The Ultra violet light is the part of electromagnetic light whose wavelength is less than the Visible light light. i.e. UV range is from 10 nm to 400 nm. UV light is invisible to the naked eye.</span>
Answer:


Explanation:
We are given that


We have to find the scalar product and the angle between these two vectors



Angle between two vectors is given by

Where
in degrees

Using formula
Where x= Coefficient of unit vector i
y=Coefficient of unit vector j


Using the formula

degrees
Hence, the angle between given two vectors=
= (3,760 joule/sec) / (4,000 joule/sec)
= 3,760 / 4,000 = 0.94 = 94%
