Answer:
See explanation for step by step explanations.
Explanation:
Let X be the mass of a randomly selected resistor
The probability density function is given as
, 80<x<120
=0, otherwise
a) By using the given pdf we have to find the probability of the resistors having resistance less than 90
=
=
=0.0625
the probability of the resistors having resistance less than 90 is 0.0625
Step 2 of 4<
/p>
b) we have to find the mean resistance
Mean=
=
=
=106.67
The mean resistance is 106.67
Answer:
When unbalanced forces act on an object at rest, the object will move. ... Second, when unbalanced forces act on a moving object, the velocity of the object will change. Remember that a change in velocity means a change in speed, direction or both speed and direction.........Eg.If you kick a football and it moves from one place to another, it means that unbalanced forces are acting upon it. Ball moves from one place to another after kicking it.
The correct answer to
the question that is stated above is letter b, <span>Plate tectonics caused lava to flow. All of the options are mentioned in the theories of the formation of the moon except for letter B.
There are 5 serious theories about the formation of the moon,these are:
</span>The Fission Theory--
The Capture Theory--
The Condensation Theory--
The Colliding Planetesimals Theory--
<span>The Ejected Ring Theory--
See attached file for the description of each theory.</span>
The complete sentence is:
<span>Centrifugal force is a fictitious force that some people believe causes you to feel as if you are being pushed outward from the center of a circle while traveling in uniform circular motion.
In fact, centrifugal force is an inertial force: it is not a real force, but it is due to the fact that the reference frame is rotating. The real force in a uniform circular motion is the centripetal force, which pushes towards the centre of the circle, and keeps the object in circular motion.</span>
Answer: λ (wavelength) = 3.3 m → ΔS = 3.3 m
v (speed) = 5.6 m/s → ΔV = 5.6 m/s
T (period) → ΔT = ?
f (frequency) = ?
If:
Now: (if, ΔT = T), Using the formula of the period of a wave, find the frequency:
