a 0.100-kg weight is attached to a spring scale. find the reading on the scale when it is not moving.

The distance between the two electrons is  q√K/2mg,where q is the charge of the electron.

The electron ( e or β ) is a subatomic molecule with a negative one rudimentary electric charge. Electrons have a place with the original of the lepton molecule family, and are by and large remembered to be rudimentary particles since they have no known parts or base

We know that force exerted by each electron on other is electrostatic force which is given by the formula,

F=(Kq₁q₂) / r²

where q₁,q₂ are the charges of the electron and r is the distance between them.

Since,both are electrons,q₁=q₂.

Now,both electrons have some mass which we assume as m.Due to presence of acceleration due to gravity,both act certain amount of force which is equal to their weight i.e.mg

So,total weight of two electrons is=2mg

Now,2mg=(Kq₁q₂) / r²

=>2mg=Kq²/r²

=>r²=Kq²/2mg

=>r=√Kq²/2mg

=>r=q√K/2mg.

Hence,distance between two electrons is q√K/2mg.

The platform will move in an upward direction at a velocity of [tex]-0.704m/s[/tex]

Frequency is a measure of the number of cycles of a periodic wave that occur in a unit of time. It is generally expressed in Hertz (Hz). One Hertz is analogous to one cycle per second.

The frequency of a wave determines its pitch. Higher-frequency waves have a higher pitch, and lower-frequency waves have a lower pitch. In sound waves, the frequency of a wave is directly proportional to the perceived pitch of the sound.

The beat frequency is then given by:

[tex]fbeat=|f'-fO|[/tex]

Setting this equal to [tex]7 Hr[/tex] and solving for v, we find:

[tex]v=(c/2)*(f_beat /fO-1)=(344/2)*(7/250-1)=-0.704m/s[/tex]

The phrase "arc second" is used in astronomy in three ways: (1) to describe a given distance in declination on a star chart, (2) as a given unit of astronomical object size, and (3) as a statement of telescope resolving ability. Circle angles may be calculated in radians since 2 times the radius equals the circumference, with 2 of these making up one full revolution. Alternatively, 0.017453 radians per degree. Multiply 206,265 arcseconds per radian to convert radians to arcseconds.

Here,

To convert the angular diameter of Betelgeuse from arcseconds to degrees, we can use the conversion factor:

1 degree = 3600 arcseconds

So, the angular size of Betelgeuse in degrees can be found by dividing the angular diameter in arcseconds by the conversion factor:

Angular size (in degrees) = Angular diameter (in arcseconds) / (3600 arcseconds/degree)

Angular size (in degrees) = 0.044 arcseconds / 3600 arcseconds/degree

Explanation:

To find the resultant of two forces when given an angle, you can use the two-dimensional vector addition method. Here are the steps to follow:

Represent each force as a vector. The magnitude of each vector should be equal to the magnitude of the force, and the direction of each vector should be equal to the direction of the force.

Place the vectors on a coordinate plane with their tails at the origin and their tips pointing in the direction of the forces.

Find the x and y components of each vector using trigonometry. For example, if the angle between the x-axis and the vector is θ, then the x-component of the vector is equal to the magnitude of the vector times cos(θ) and the y-component of the vector is equal to the magnitude of the vector times sin(θ).

Add the x and y components of the two vectors to find the x and y components of the resultant vector.

Use the Pythagorean theorem to find the magnitude of the resultant vector. The magnitude of the resultant vector is equal to the square root of the sum of the squares of the x and y components.

Find the direction of the resultant vector by finding the inverse tangent (tan^-1) of the ratio of the y-component of the resultant vector to the x-component of the resultant vector.

The final result is the vector that starts at the origin and ends at the point determined by the x and y components of the resultant vector, with a magnitude equal to the magnitude of the resultant vector and a direction equal to the direction of the resultant vector.

By using this method, you can find the magnitude and direction of the resultant of two forces given an angle between them.

40.08 m/s is the distance between the ships changing at 8:00 p.m. if ship a is 200 km west of ship b. ship a is sailing south at 34 km/h.

Let's consider a coordinate system with Ship B at the origin (0,0), and Ship A at point (200,0). Then, Ship A is moving in the negative y direction with a speed of 34 km/h, and Ship B is moving in the positive y direction with a speed of 21 km/h.

The distance between the ships is given by the distance formula:

d = √((x2 - x1)² + (y2 - y1)²) = √(200² + (y2 - y1)²),

where x1 and x2 are the x-coordinates, and y1 and y2 are the y-coordinates of the two ships.

The rate of change of the distance between the ships is equal to the derivative of d with respect to time:

d/dt = √(200² + (dy/dt)²),

where dy/dt is the relative velocity of the two ships.

At 8:00 p.m., the relative velocity is 34 km/h - 21 km/h = 13 km/h = (13 * 1000/3600) m/s. So,

d/dt = √(200² + (13 * 1000/3600)²) = √(200² + (13² * 1000²/3600²)) m/s

d/dt = √(200² + (13² * 1000²/3600²)) m/s = √(200²+ (13² * 1000²/3600²)) m/s = 40.08 m/s.

The magnitude of the police car's constant acceleration is 23 m/s² to catch the speeding car after the police car travels a distance of 356 m .

Let's call this time t.

The distance covered by the police car is calculated as follows:

                             d =  v0t + (1/2)at²,

where a is the acceleration,

t is the amount of time it takes to catch the fast car, and

                    v0 is the initial velocity (0 m/s).

If we set this at 356 m, we have:

We are able to isolate t:

                    t = (356/(1/2at²))

The next step is to determine the police car's relative speed to the fast car.

When we set v equal to the speed of the fast car (37 m/s), we get:

                            v = v0 + at

                                     37 = at

Since we now have t and a, we can put t back into the equation instead of

                      v: 37 = a√(356/(1/2a)) + (0 m/s)

Expanding the right side:

                                  37 = a√(356/0.5a)

divided by a on both sides:

                                    37/a = 356/0.5a

Squaring both sides:

                                    1369/a²= 356/0.5a

Expanding the right side:

                                         1369/ a² = 712/a

Cross-multiplication:

                    a³ = 1369 × 0.5 × a

Divided by a on both sides:

                                    a²  = 1369/2

Using both sides' square roots:

                                           a² = 1369/2

                                           a = √(1369/2)

                                           a = 23 m/s²,

so the magnitude of the police car's constant acceleration is 23 m/s².

Radio waves are most likely to be non-ionizing radiation.

Electromagnetic radiation can be classified into ionizing or non-ionizing radiation, depending on its ability to ionize atoms or molecules in its path. Ionizing radiation has enough energy to remove electrons from atoms or molecules, while non-ionizing radiation lacks sufficient energy to do so.

Radio waves have the lowest frequency and energy among the different types of electromagnetic radiation in the electromagnetic spectrum. They have a wavelength range of 1 millimeter to 100 kilometers, and their energy is typically below 10^-4 electron volts, which is not enough to ionize atoms or molecules. As a result, radio waves are classified as non-ionizing radiation.

On the other hand, ultraviolet, X-rays, and gamma rays have higher frequencies and energies than radio waves and are classified as ionizing radiation. Ultraviolet radiation has enough energy to ionize atoms or molecules in the air, causing sunburn and other skin damage. X-rays and gamma rays have enough energy to penetrate through materials, including human tissues, and can cause cellular damage or mutations if exposure occurs.

The depth of penetration of the 100kg projectile into the ground is 5.09 meters.

How does the height of release affect the depth of penetration?

The height of release affects the depth of penetration in that a higher release point will result in a higher initial velocity for the projectile. This in turn will cause a deeper penetration into the ground upon impact.

The depth of penetration of the 100kg projectile into the ground can be calculated using the following formula:

d = (v^2)/(2g), where v is the velocity upon impact and g is the acceleration due to gravity.

Assuming no air resistance, the velocity upon impact can be calculated as v = √(2gh) = √(2 * 9.8 * 100) = 44.72 m/s.

Plugging in this value into the formula gives d = (44.72^2)/(2 * 9.8) = 508.57 cm or 5.09 meters.
