Explanation:
3. When a magnetic sector instrument was operated with an accelerating voltage of 4.50*103 V, a field of 0.251 T was required to focus the CH4 on the detector. a) What range of field strengths would be required to scan the mass range between 12.5 and 2.50*102 , for singly charged ion, if the accelerating voltage is held constant
Answer:
The answer is "[tex]4,500 - 225 \ V[/tex]".
Explanation:
Using formula for calculating the Voltage:
[tex]M_1=12.5\\\\M_2=250\\\\V_1=4,500 \\\\\bold{\text{Formula: }}\\\\\to \bold{\frac{m_1}{m_2}=\frac{V_2}{V_1}}\\\\\to \frac{12.5}{250}=\frac{V_2}{4,500}\\\\\to 0.05=\frac{v_2}{4,500}\\\\\to 0.05\times 4,500= V_2\\\\\to V_2=225\\\\[/tex]
Hence the range of accelerating in voltage is [tex]4,500 - 225 \ V[/tex]

How has the theory of the Universe changed over time?
Suppose you are planning a trip in which a spacecraft is to travel at a constant velocity for exactly six months, as measured by a clock on board the spacecraft, and then return home at the same speed. Upon return, the people on earth will have advanced exactly 90 years into the future. According to special relativity, how fast must you travel
Answer:
v = 0.99 c = 2.99 x 10⁸ m/s
Explanation:
From the special theory of relativity:
[tex]t = \frac{t_o}{\sqrt{1-\frac{v^2}{c^2} } }\\[/tex]
where,
v = speed of travel = ?
c = speed of light = 3 x 10⁸ m/s
t = time measured on earth = 90 years
t₀ = time measured in moving frame = 6 months = 0.5 year
Therefore,
[tex]90\ yr = \frac{0.5\ yr}{\sqrt{1-\frac{v^2}{c^2} } } \\\\\\\sqrt{1-\frac{v^2}{c^2}} = \frac{0.5\ yr}{90\ yr}\\ 1-\frac{v^2}{c^2} = 0.00003086\\\frac{v^2}{c^2} = 1-0.00003086\\[/tex]
v = 0.99 c = 2.99 x 10⁸ m/s
How is the gravity between two objects affected by their masses?
Answer:
Objects with greater mass have a stronger force of gravity between them. Objects that are closer together have a stronger force of gravity between them.
Explanation:
Newton's law states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.

A flywheel having constant angular acceleration requires 4.00 ss to rotate through 164 radrad . Its angular velocity at the end of this time is 106 rad/srad/s . Find the angular velocity at the beginning of the 4.00 ss interval; the angular acceleration of the flywheel. For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Rotation of a bicycle wheel.
Answer:
[tex]\omega '=-13.5rad/s[/tex]
Explanation:
From the question we are told that:
Time [tex]t=4sec[/tex]
Angular displacement [tex]\theta= 161 rad[/tex]
Final Angular velocity [tex]\omega = 100 rad / s[/tex]
Let
Angular acceleration [tex]\alpha[/tex]
Generally the equation for Initial Angular velocity [tex]\omega '[/tex] is mathematically given by
[tex]-\omega '^2=2 \alpha \theta -\omega^2[/tex]
[tex]\omega '^2= \alpha 328 +11236[/tex]
Also,Initial Angular velocity [tex]\omega '[/tex] is mathematically given by
[tex]\omega '=\omega - \alpha t[/tex]
Therefore substitution
[tex]-\omega '^2=2 \alpha \theta -\omega^2[/tex]
[tex]\omega '=\omega - \alpha t[/tex]
[tex](\omega - \alpha t)^2=2 \alpha \theta -\omega[/tex]
[tex]-16\alpha^2+848\alpha+11236= \alpha 328 -11236[/tex]
[tex]16\alpha^2-520\alpha=0[/tex]
[tex]\alpha=29.875rads/s^2[/tex]
Substitution in the 2nd equation for Initial Angular velocity [tex]\omega '[/tex]
[tex]\omega '=106-(29.875rads/s^2*4)[/tex]
[tex]\omega '=-13.5rad/s[/tex]

Sarah is a 30 year old white female. Her occupation is part time chef. She is recently been divorced and has custody of
her three children. She has extreme changes in her mood that began to appear in her 20's but she never went to
see a
doctor about them. When family tries to talk to her about her upset, she reacts by becoming angry and blaming them
for her situation. She is currently complaining of crying episodes, not eating, headaches, thinking she is a failure,
spending most of her time in bed, and not being interested in activities she once enjoyed doing with her kids, such as
going to the park and seeing movies. Her mother and grandfather also showed signs of mental illness and she
reported that her mom has taken Depakote before, which helped. Sarah wants to open her own restaurant and move to
a bigger house.
1. Please answer the following questions by referring to the above case study and the assigned reading for this
unit:
• What psychological and physical symptoms does Sarah present with?
. What is the primary psychological disorder diagnosis that fits her symptoms based on the disorders
described in the textbook?
Answer:
how to deal with devoirce
Explanation:
The psychological and physical symptoms that Sarah presents include:
She frequently has headaches.She also has a loss of appetite.She gets angry easily.From the information given, we can infer that some of the symptoms include the fact that Sarah frequently has headaches, loss of appetite, and gets angry easily.
The primary psychological disorder diagnosis that fits her symptoms based on the disorders will be depression. She's depressed because she just got divorced. This has taken a toll on her health.

How much far is the Moon from Earth if it takes light 8.53 hours to travel there?
Answer:
9.21x10¹² m
Explanation:
In order to solve this problem we need to move the speed at which light moves. That value can be readily found on textbooks:
c = 3x10⁸ m/sThen we can use the formula for speed:
Speed = distance / timeDistance = Speed * timeWhere in this case Speed is c, and the time is 8.53 hours.
Now we convert 8.53 hours into seconds:
8.53 hr * [tex]\frac{60min}{1hr}*\frac{60s}{1min}[/tex] = 30708 sFinally we calculate the distance:
3x10⁸ m/s * 30708 s = 9.21x10¹² mASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP NEED HELP ASAP

how are dams made do they just freeze time?
Answer:
Gravity dams are so named because they are held to the ground by gravity – they weigh a lot, and are typically made from concrete or stone. Engineers must de-water the river where the dam is meant to be built. This is done by diverting the river through a tunnel that runs around the intended construction zone.
Answer:First, they dug tunnels from below the dam to above the dam. Then, they put the cofferdam in place, and opened the tunnels. The water flowed around the site where the permanent dam would be built until they were done, at which point the cofferdam was removed.

meters and t is in second
find the
il amplitude
i frequency
wavelengths
velocity of the Progress in
waveم ا )
Answer:
Amplitude = 0.02m
Frequency = 640 Hz
Wavelength, λ = 0.5m
v = 320 m/s
Explanation:
Given the wave equation :
y=0.02 sin2π/0.5 (320t - x) where x and y are in
meters and t is in second
Comparing the above relation with the general wave equation :
y(x, t) = Asin2π/λ(wt - kx)
The amplitude, A = 0.02
From the equation :
2π/0.5 = 2π/λ
λ = 0.5 m
320t = vt
Hence, v = 320 m/s
Recall :
v = fλ
320 = f * 0.5
f = 320 / 0.5
f = 640 Hz
