How does mud stone turn into metamorphic rock

Explain the necessity of smoothing the output voltage before applying it to a transistor

ra1l [238]

In simple words, smoothing can be defined as the circuit which is done to eliminate the ripple from the yield of a direct current power supply.

<u>Explanation:</u>

<u>Necessity of smoothing:</u>

Smoothing can be also applied in the form of a capacitor that acts to decrease or level out variations in a signal. And these capacitors are mostly used after power supply in voltage.
The yield DC voltage of a half-wave rectifier provided in the figure of a sinusoidal wave.
In a method to provide a constant DC voltage from a corrected AC source, a filter or smoothing circuit is required.

A 100-kg astronaut is floating in outer space. If the astronaut throws a 2-kilogram wrench at a speed of 10 meters per second, w

sergey [27]

Since Astronaut and wrench system is isolated in the space and there is no external force on it

So here momentum of the system will remain conserved

so here we can say

$m_1v_{1i} + m_2v_{2i} = m_1v_{1f} + m_2v_{2f}$

initially both are at rest

so here plug in all values

$0 = 100 v_{1f} + 2\times 10$

$v_{1f} = -0.20 m/s$

so here the astronaut will move in opposite direction and its speed will be equal to 0.20 m/s

1. What is the acceleration of a point on the edge of a 0.30 m diameter grinding wheel rotating at 1600 rpm?

anygoal [31]

Complete Question

1. What is the linear speed of a point on the edge of a 0.30 m diameter grinding wheel rotating at 1600 rpm?

2. What is the acceleration of the point?

Answer:

1

$v = 25.14 \ m/s$

2

$a = 4013.5 \ m/s^2$

Explanation:

From the question we are told that

The diameter is $d = 0.30 \ m$

The angular speed is $w = 1600 \ rpm = \frac{ 1600 * 2 * \pi }{60 } = 167.6 \ rad /s$

Generally the is mathematically represented as

$r = \frac{d}{2} = \frac{0.30}{2 } = 0.15 \ m$

Generally the linear speed is mathematically represented as

$v = wr$

$v = 167.6 * 0.15$

$v = 25.14 \ m/s$

Generally the acceleration is mathematically represented as

$a = \frac{v^2 }{r}$

$a = \frac{25.14^2}{0.15}$

$a = 4013.5 \ m/s^2$

The_______theory of matter states that all particles of matter are in constant motion.

MA_775_DIABLO [31]

<u>Answer </u>

kinetic

<u>Explanation</u>

Matter is anything that occupies space and has mass. There are four states of matter, solids, liquids, gases and plasma. All this consist of small molecules that are in constant random motion. This is called kinetic theory of matter.

When these molecules are in motion they may collide. No energy is gained or lost during collision. The particle/molecules move in a constant linear motion.
