Lower than the natural frequency when only one person is on the swing. This is because the second person's added weight increases the swing's effective mass, making it oscillate more slowly.

The relationship between the natural frequency and the effective mass of a system can be described by the equation:

f = (k / (2 * pi * m))^0.5

Where f is the natural frequency, k is the system's spring constant (related to the stiffness of the swing), m is the effective mass, and pi is the mathematical constant pi (approximately equal to 3.14).

Since the effective mass of the system increases when two people sit on the swing, the natural frequency will decrease. This means that the new natural frequency of the swing is lower than the natural frequency when only one person is on the swing.

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]

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.

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

Betelgeuse has an angular dimension of around 0.0000122 degrees.

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

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.

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.

In summary, radio waves are non-ionizing radiation, while ultraviolet, X-rays, and gamma rays are ionizing radiation.

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.
