In the figure, particle 1 of mass m1 = 3.1 kg slides rightward along an x axis on a frictionless floor with a speed of 5.0 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2 = 4.6 kg. When particle 2 then reaches a wall at xw = 79 cm, it bounces from the wall with no loss of speed. At what position on the x-axis does particle 2 then collide with particle 1?

and particle 2 is " gaining " at a rate of (10/7)m/s leftward ; this is their relative velocity at that time . Thus , this "gap" of 23cm between them will be closed after an additional time of (0.23m)/(10/7m/s)=0.16s has passed . At this time (t=0.82+0.16=0.98s) the two particles are at x=(−2/7)(0.98)=−28cm

Assume that you have a wireless application you would like to design,build and sell as a commercial product.You have selected a target frequency in the UHF range.How would you decide what frequency to use and how would you get permission to use it ?

Answers

The frequency to use depends on the range and distance of signal transmission. There is government communication agency in charge of issuing license in order to get carrier frequency in which the application can work with.

UHF means Ultra - high frequencies which is mostly used in television broadcasting and mobile phone. Frequency range of the UHF is between 300MHz to 3GHz.

Assuming that you have a wireless application you would like to design, build and sell as a commercial product. And you have selected a target frequency in the UHF range.

Most wireless applications make use of radio wave and microwave depending on the range of distance in which the signal will travel.

The first thing to do is to determine the distance. Whether is short or long distance.Then get a license from the right  government communication agency so that a carrier wave frequency will be allocated for you.  Determine the side bands frequencies and Calculate the bandwidth

Bandwidth = 2[tex]F_{s}[/tex]

Where [tex]F_{s}[/tex] = sidebands frequency

Purchase all the necessary devices and gadgets like transmitter, oscillator, antenna e.t.c

The bullet points above highlighted how  you can decide what frequency to use and how would you get permission to use it

Answer:

Explanation:

As horsepower is the rate  at which that force torque  is a twisting or turning force, horsepower is produced. Hence option  C is correct.

What is horsepower?

Horsepower is defined as a unit used to describe the pace at which labor is done or to quantify power, frequently in relation to the output of engines or motors. Standardization and types of horsepower vary widely. A car's engine power is measured in horsepower (hp); the greater the number, the more power is transferred to the wheels and, in theory, the faster it will travel.

To put it simply, horsepower is your overall speed and power, whereas torque allows you to feel the sensation of acceleration when you put your foot down. When you realize that horsepower is derived from torque, this makes sense. Torque is a unit of rotational or twisting force. The power an engine produces is referred to as horsepower.

Thus, as horsepower is the rate  at which that force torque  is a twisting or turning force, horsepower is produced. Hence option  C is correct.

Internal combustion engine is dependent on the heat of combustion so as to make torque to move the vehicle and power the system.

A lot of heat made during combustion is not often used productively and therefore need to be removed to avoid overheating of the engine.

The heat energy that is not used for is wasted in three ways: They are:

About 33% is wasted by being dumped straight out of the exhaust to the atmosphere. About 33% is wasted by the cooling system, which prevents overheating of the engine components. About 5% is wasted by internal friction and from radiating off of hot engine components straight to the atmosphere.

An egg with an initial temperature 25C was place into a boiling water for 15 minutes. Heat from the boiling water enters the egg and changes its temperature gradually over time and space. Using the 2 dimensional finite element method, prove that the temperature of the egg varies from the shell to the center of the egg. You may need to develop your own nodes before start deriving the equations.

Answers

It is proved from the below that the temperature of the egg varies from the shell to the center of the egg.

Using the 2-dimensional finite element method, we will need to find the Biot number of the system by using the formula:

[tex]\mathbf{Bi = \dfrac{h_c r_o}{k} }[/tex]

According to the Heisler chart, the curves in the graph represent a range of values for the inverse of the Biot number,

where;

[tex]\mathbf{Bi = \dfrac{h_c r_o}{k} }[/tex]

here;

k = the material's thermal conductivity h = the heat transfer coefficient.

By developing nodes based on assumptions;

[tex]\mathbf{Bi = \dfrac{1700 \times 0.025}{0.682} }[/tex]

Bi = 62.32

The inverse of Biot number is:

[tex]\mathbf{=\dfrac{1}{Bi}}[/tex]

[tex]\mathbf{=\dfrac{1}{62.32}}[/tex]

= 0.016

Similarly, the Fourier number [tex]\mathbf{F_o}}[/tex] is calculated by using the expression;

[tex]\mathbf{F_o = \dfrac{\alpha t }{r_o^2} }[/tex]

[tex]\mathbf{F_o = \dfrac{k t }{\rho c_pr_o^2} }[/tex]

where;

time (t) = 15 mins = (15 × 60) sec

[tex]\mathbf{F_o = \dfrac{0.682 \times 15 \times 60 }{958.4 \times 4211 \times 0.025^2} }[/tex]

[tex]\mathbf{F_o = 0.243}[/tex]

Using the 2-dimensional finite element method, the temperature ratio is:

[tex]\mathbf{\dfrac{T(0,t) -T_{\infty}}{T_o -T_{\infty}} = 0.1 }[/tex]

T(0,t) = 100 + 0.1(4-100)

T(0,t) = 100 + 0.1(-96)

T(0,t) = 100 - 9.6

T(0, t) = 90.4° C

Therefore, we can conclude that it is proved that the temperature of the egg varies from the shell to the center of the egg.
