Answer:
a
The largest diameter is [tex]d = 0.523 \ m [/tex]
b
The number of revolution is [tex]n = 2.132 *10^{4}[/tex]
Explanation:
From the question we are told that
The kinetic energy of the electron is [tex]K = 6.5 MeV = 6.5 *10^6 * 1.60 *10^{-19} = 1.04 *10^{-12} \ J[/tex]
The magnetic field is [tex]B = 1.4 \ T[/tex]
The time is [tex]t = 1 ms = 1*0^{-3} \ s[/tex]
Generally the kinetic energy of the proton is mathematically represented as
[tex]KE = \frac{1}{2} * m * v^2[/tex]
Here m is the mass of the proton with a value [tex]m = 1.672 *10^{-27} \ kg[/tex]
=> [tex]v = \sqrt{ \frac{2 * K }{ m} }[/tex]
=> [tex]v = \sqrt{ \frac{2 * 1.04 *10^{-12} }{ 1.672 *10^{-27}} }[/tex]
=> [tex]v = 3.5271 * 10^{7} \ m/s [/tex]
Generally the radius of the largest orbit is mathematically represented as
[tex]r = \frac{ m * v}{ B * e}[/tex]
Here e is the charge on a proton with the value [tex]e = 1.60 *10^{-19} \ C[/tex]
[tex]r = \frac{ 1.672 *10^{-27} * 3.5271 * 10^{7} }{ 1.4 * 1.60 *10^{-19} }[/tex]
=> [tex]r = 0.261 \ m [/tex]
Generally the diameter is
[tex]d = 2 * r[/tex]
=> [tex]d = 2 * 0.261[/tex]
=> [tex]d = 0.523 \ m [/tex]
Gnerally the period of revolution round the orbit is mathematically represented as
[tex]T = \frac{2 \pi * m }{B * e}[/tex]
=> [tex]T = \frac{2 * 3.142 * 1.672 *10^{-27} }{1.4 * 1.60 *10^{-19}}[/tex]
=> [tex]T = 4.691 *10^{-8} \ s [/tex]
Generally the number of revolution is mathematically represented as
[tex]n = \frac{t}{T}[/tex]
[tex]n = \frac{1*10^{-3}}{4.691 *10^{-8} }[/tex]
[tex]n = 2.132 *10^{4}[/tex]
. A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.
A ball is dropped from an upper floor, some unknown distance above Tom's apartment. As he looks out of his window, which is 1.10 m tall, Tom observes that it takes the ball 0.190 s to traverse the length of the window. Determine how high ℎ above the top of Tom's window the ball was dropped. Ignore the effects of air resistance.
Answer:
The height is 1.20 m above the window.
Explanation:
Given that,
Height of window = 1.10 m
Time = 0.190 sec
We need to calculate the velocity
Using equation of motion
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
Put the value into the formula
[tex]1.10=u\times0.190+\dfrac{1}{2}\times9.8\times(0.190)^2[/tex]
[tex]1.10=u\times0.190+0.17689[/tex]
[tex]u=\dfrac{1.10-0.17689}{0.190}[/tex]
[tex]u=4.85\ m/s[/tex]
We need to calculate the height
Using equation of motion
[tex]v^2=u^2+2gh[/tex]
Put the value into the formula
[tex](4.85)^2=0+2\times9.8\times h[/tex]
[tex]h=\dfrac{(4.85)^2}{2\times9.8}[/tex]
[tex]h=1.20\ m[/tex]
Hence, The height is 1.20 m above the window.

2. In the activities below indicate if friction is useful or not useful? Explain your answer. i. Writing yes it is useful because when your writing because friction helps you see what your writing ii. Rubbing iii. Skiing iv. Rotating a wheel
Answer:
Please find the answer in the explanation
Explanation:
Friction is a force that opposes motion. One or two of the advantages of friction are break and ability of an object to walk.
Writing yes it is useful because when your writing because friction helps you see what your writing
ii. Rubbing. Yes, it is useful.
friction make it possible for two object to rub each other
iii. Skiing. No. It is not useful because With presence of friction, skiing will not be possible.
iv. Rotating a wheel No. It is not useful because Friction will oppose the rotation of the wheel.

How much is the current in a light bulb whose resistance is 350 ohms when the bulb is connected to a 110-volt outlet?
Answer:
0.31429 Amps
Explanation:
Using the "Ohm's Law" we can look for the current (amps) with a formula of I = V/R
Given:
Resistance (Ohm) = 350
Volts = 110
Solution:
I = 110v/350r
I = 0.31429 amps
Need HELP ASAP PLEASE THANK YOU TO ANYBODY THAT HELPS!!!!!!!!!!!!!!
Answer:
the slop is y x ray down
Explanation:
In a circuit, a variable resistor is to be connected across a potential difference of 60 volts to allow the current to be adjusted in the range from 40 milliamperes to 100 milliamperes.
A variable resistor is a device in which the resistance can be varied.
mA = milliamperes, or 10-3 amperes
Over what range must the resistance vary?
plz help :')
Answer:
600 and 1500 [ohm
Explanation:
To solve this problem we must use ohm's law, which tells us that the voltage is the product of the current by the resistance, so we have:
V = I*R
where:
V = voltage [V]
I = current [amp]
R = resistance [ohm]
Therefore:
R = V/I
R1 = 60/(40*10^-3) = 1500 [ohm]
R2 = 60/(100*10^-3) = 600 [ohm]
So the resistance should be among 600 and 1500 [ohm]
Problem #1- In the first scene in which Miss Clark appears, she is supposed to be wearing a BLACK dress.
The only available dress that will fit the student playing this role is RED. There is no money in the budget to
purchase another dress. What can be done to the lighting on the stage to make the RED dress APPEAR
BLACK?
Answer:
Blue Lighting
Explanation:
In order to make red look black, you must use blue light. The blue would be absorbed and there would be no red light to reflect.
Answer:
You would have to shine green Light on the actress to make the dress appear to be red.
Explanation:
The reason it would appear to be red is because green reflects the red colour and absorbs the rest. So, when green light is shone on the dress, it absorbs all of the green light and not reflecting anything.The dress then appears to beblack.

An old man standing at the edge of a seaside cliff kicks a stone over the edge with a speed of 14 m/s. The cliff is 63.5 m above the water's surface.
a. How long does it take the stone to fall to the water?
b. With what speed does the stone strike the water?
Answer:
a) t=3.6 sec
b) [tex]\mid v \mid =38\ m/s[/tex]
Explanation:
Horizontal Motion
When an object is thrown horizontally with a speed v from a height h, it describes a curved trajectory ruled by a constant speed in the horizontal direction and a variable speed in the vertical direction, where the acceleration of gravity makes the object fall to the ground.
If we know the height h from which the object was launched, the time it takes to hit the ground is:
[tex]\displaystyle t=\sqrt{\frac {2h}{g}}[/tex]
The horizontal speed is always constant:
vx=vo
But the vertical speed depends on the time and acceleration of gravity:
[tex]vy=g\cdot t[/tex]
The magnitude of the velocity or final speed of the object is given by:
[tex]\mid v \mid =\sqrt{vx^2+vy^2}[/tex]
a.
The stone was kicked over the cliff with a speed of v0=14 m/s, and the height it was thrown from is h=63.5 m, thus:
[tex]\displaystyle t=\sqrt{\frac {2\cdot 63.5}{9.8}}[/tex]
t=3.6 sec
b.
The vertical speed is:
[tex]vy=9.8\cdot 3.6[/tex]
vy=35.3 m/s
The final speed is calculated below:
[tex]\mid v \mid =\sqrt{14^2+35.3^2}[/tex]
[tex]\mid v \mid =\sqrt{1,442.09}[/tex]
[tex]\boxed{\mathbf{\mid v \mid =38\ m/s}}[/tex]
