Explanation:
Two charged particles, with charges q1 = q and q2 = 4q are located at a distance d = 2cm apart on the x axis A third charged particle, with charge q3 = q is placed on the x axis such that the magnitude of the force that charge 1 exerts on charge 3 is equal to the force that charge 2 exerts on charge 3. Find the position of charge 3 when q = 10n C
Answer:
0.667 cm
Explanation:
|F_1on3| = |F_2on3|
k×q1×q3/x^2 = k×q2×q3/(d-x)^2
q1/x^2 = q2/(d-x)^2
(d-x)^2/x^2 = q2/q1
(d-x)/x = sqrt(q2/q1)
(2 - x)/x = sqrt(4×q/q)
(2 - x)/x = 2
2 - x = 2x
2 = 3x
x = 2/3
x= 0.667 cm

HELPPP BESTIESSS An astronomer is studying two stars that have about the same size and brightness. From the Earth, one of the stars appears very bright in the night sky. The other star appears very faint and dim.
Why does one star appear to be brighter than the other?
A. The Earth is moving toward the brighter star.
B. The Earth is moving toward the dimmer star.
C. The Earth is farther from the brighter star.
D. The Earth is closer to the brighter star.
Answer:
If the stars are about the same size and brightness then the earth must be nearer to the stat that appears brighter, The stars movement, nearer or farther, would only effect the frequency received (redshift).
Answer:
D- The earth is closer to the bright star
Explanation:
If two stars have SAME brightness and size then that means the only point of difference is distance . Earth should be closer to the brighter star for the star to be bright.

A wire has resistivity of 0.12 homes per metre.
a)Find the resistance of 25m of wire.
b)Find the length of this wire that has resistance 22ohms
Answer:
(a) The resistance of 25m of wire is 3 ohms
(b) the length of this wire that has resistance 22 ohms is 183.33 m
Explanation:
Given;
resistivity of the wire, ρ = 0.12 ohms per meter
(a) The resistance of 25m of wire is calculated as follows;
[tex]R = \rho L\\\\R = 0.12 \ \frac{ohms}{m} \times 25\ m\\\\R = 3 \ ohms[/tex]
(b) the length of this wire that has resistance 22 ohms is calculated as;
[tex]L = \frac{R}{\rho} \\\\L = \frac{22 \ ohms }{0.12 \ ohms/m} = 183.33 \ m[/tex]
Define normal force in words
Answer:
The normal force is the force that surfaces exert to prevent solid objects from passing through each other. If the object is at rest, the net force on the object is equal to zero. Therefore, the downward force (weight) must be equal to the upward force (normal force).
2. Calculate the kinetic energy of a football being launched downfield by Patrick Mahomes. The football has a mass of .5 kg and is thrown at a velocity of 25 m/s. Find the kinetic energy.
Answer:
K.E = 156.25 Joules.
Explanation:
Given the following data;
Mass = 0.5kg
Velocity = 25 m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
[tex] K.E = \frac{1}{2}0.5*25^{2}[/tex]
[tex] K.E = 0.25 * 625 [/tex]
K.E = 156.25 Joules.

A wave traveling at 5.00x10^4 meters per second has a wavelength of 2.50x10^1 meters what is the frequency of the wave
Answer:
Frequency of the wave = 2 x 10³ hz
Explanation:
Given:
Velocity of wave = 5 x 10⁴
Wavelength = 2.5 x 10¹
Find:
Frequency of the wave
Computation:
Frequency of the wave = Velocity of wave / Wavelength
Frequency of the wave = [5 x 10⁴] / [2.5 x 10¹]
Frequency of the wave = 2 x 10³ hz
The frequency of a wave traveling at 5.00 x 10⁴ meters per second and a wavelength of 2.50x10¹ meters is 2 × 10³ Hz
HOW TO CALCULATE FREQUENCY:
The frequency of wave can be calculated by dividing the speed of the wave by its wavelength.λ = v/f
Where,
V= velocity of the wavef = frequencyλ = wavelengthAccording to this question, a wave is traveling at 5.00 x 10⁴ m/s and has a wavelength of 2.50 x 10¹ meters. The frequency can be calculated as follows:f = v ÷ λf = 5 × 10⁴ ÷ 2.5 × 10¹f = 2 × 10³HzTherefore, the frequency of a wave traveling at 5.00 x 10⁴ meters per second and a wavelength of 2.50x10¹ meters is 2 × 10³Hz.Learn more at: https://brainly.com/question/19601903?referrer=searchResults

Suppose the equation of the velocity of a car at any given time is Vx= 30m/s+(2.5m/s^3)t^2 Find the change in the velocity of the car during time t1= 4s and t2= 5.5s (a) 70.00 m/s (b) 105.63 m/s (c) 35.63 m/s (d) 175.63 m/s
Answer:
time=4, answer choice A
time=5.5, answer choice B
Explanation:
This is taken from the kinematic equation, v=vo+(1/2)at^2
Velocity at time 4 = 30+(2.5)(4)^2
Velocity at time 5.5 = 30+(2.5)(5.5)^2
Velocity at time 4 seconds = 70 m/s
Velocity at time 5.5 seconds = 105.63 m/s
Three vectors A,B and C are such that A=B+C and their magnitudes are 5,4 and 3 respectively.find the angle between A and C
Answer:
B = A - C
=> B² = A² + C² - 2AC.cos(A,C)
=>
[tex]cos(a.c) = \frac{a {}^{2} + c {}^{2} - b {}^{2} }{2ac} = \frac{5 {}^{2} +3 {}^{2} - 4 {}^{2} }{2.5.3} = \frac{3}{5} [/tex]

Light travels through air faster than it travels through water. How would
the light refract differently if the keys were in air, and the boy was looking
at them from underwater?
Answer:
The fastest thing in the whole universe is the speed of light in a vacuum (like outer space!), clocking in at a great 2.99 x 108 m/s. Light travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through.

Two objects have a force of gravity of 100 N. If the distance between both objects decreases by a factor of 7, while the masses both decrease by a factor of 8. What is the new Fg?
The gravitational force F between two masses M and m a distance r apart is
F = G M m / r ²
Decrease the distance by a factor of 7 by replacing r with r / 7, and decrease both masses by a factor of 8 by replacing M and m with M / 8 and m / 8, respectively. Then the new force F* is
F* = G (M / 8) (m / 8) / (r / 7)²
F* = (1/64 × G M m) / (1/49 × r ²)
F* = 49/64 × G M m / r ²
In other words, the new force is scaled down by a factor of 49/64 ≈ 0.7656, so the new force has magnitude approx. 76.56 N.
