Y’all this assignment determines if i pass , please help me out.. Part 2: Graphing the Effect of Changing Mass and Velocity on K

jarptica [38.1K]

Answer:

* energy is proportional to masses. in a graph it would look like a line

* kinetic energy varies with the square of the velocity, In a graph it gives rise to a quadratic curve

Explanation:

Kinetic energy is defined by

K = ½ m v²

when analyzing this expression we can see:

* energy is proportional to masses. Therefore, doubling the mass doubles the kinetic energy and if the mass rises 4 times the energy rises 4 times, that is, they are directly proportional, in a graph it would look like a line

* kinetic energy varies with the square of the velocity. Therefore by doubling the speed the energy goes up 4 times. In a graph it gives rise to a quadratic curve

A series RC circuit contains a 1,000 ohm resistor and a 0.025 microfarad capacitor. What is the time constant of this circuit?

stiks02 [169]

The RC time constant, also called tau, the time constant (in seconds) of an RC circuit, is equal to the product of the circuit resistance (in ohms) and the circuit capacitance (in farads), i.e.

$\tau = RC$

Here,

R = Resistance

C = Capacitance

Replacing we have that

$\tau = (1000)(0.025*10^{6})$

$\tau = 25*10^{-6}$

$\tau = 25\mu s$

Therefore the time constant of this circuit is $\tau = 25\mu s$

Compare the outermost electrons of an atom with the inner most electrons of an atom in terms of energy

iris [78.8K]

The innermost electron of an atom has the lowest level of energy while the outermost electron has the highest level of energy.
There are different energy levels in the atoms of elements, for an atom to go into an higher level it has to obtain more energy and to go to lower level it has to lose energy.<span />

Higher amplitudes sound will have a _____________________ sound while lower amplitude will have a __________________________ sou

lukranit [14]

Answer:

9) HIGHER AND LOWER INTESITY, 10) speed of sound must decrease.

11) guitar the strings, flute, 12) In the mountains, 13) sound of a low frequency horn (sub-wofeer)

Explanation:

In this exercise we are asked to complete the sentences.

9) the intensity of the sound is the square of the amplitude, the missing words are

HIGHER INTESITY

LOWER INTENSITY

10) the speed of sound is

v = $\sqrt{\frac{B}{\rho} }$

and it is also related to temperature

v = $v_o \sqrt{1+ \frac{T}{273} }$

We must be careful since the compressibility modulus (B) changes significantly between the solid, liquid and gaseous states, if we are in the same medium, the speed of sound decreases with increasing density. For a higher density the speed of sound decreases

Also the speed of sound increases with temperature, but its effect is less,

Therefore, by having these two effects in the opposite direction, the change in density is more important, so the speed of sound must decrease.

.

11) when you listen to a guitar the strings resonate with the instrument body

on the flute has a resonance between the blown air and the flute tube

12) When you are in front of a tall object, the sound is reflected and the echo is heard.

In the mountains, in the squares where there is a large object that reflects in sound

13) when we hear the sound of a low frequency horn (sub-wofeer) we feel the vibration of the air, this is an effect of the pressure energy of the sound on our chest
