Exactly C ; two spaceships approaching each other move at very close to the speed of light, each sending a beam of light to the other. each measures the speed of light from the other spaceship is 'C'.
A fundamental physical constant, typically abbreviated as c, the speed of light in a vacuum is significant in many branches of physics. 299,792,458 meters per second is the precise speed of light, or c. (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour). [Note 3] The special theory of relativity states that the maximum speed at which ordinary matter or energy (and thus any signal carrying information) may move across space is c.
Including visible light, all types of electromagnetic radiation move at the speed of light. Light and other electromagnetic waves will appear to propagate instantly for many practical uses, but for very sensitive measurements over great distances, their finite speed has noticeable impacts.

Determine the magnitude of the initial vertical velocity of the projectile, viy, when the magnitude of its initial velocity, vi, was 40. meters per second. [1]
A projectile was fired with initial velocity of 40 m/s and at angle 30⁰ above the horizontal. Its initial vertical velocity is 20 m/s.
In a projectile motion, at a time instant t, the velocity v can be divided into its horizontal and vertical components: vx and vy. Let the projectile is fired at angle θ above the horizontal, then:
vx = v cos θ
vy = v sin θ
Where:
v = velocity at time instant t
Parameters given:
v = 40 m/s
θ = 30⁰

The final rotation rate of the person, after the wheel has slowed according to conservation of angular momentum is 0.5 rev/sec.
Conservation of angular momentum is a physical property of a spinning system in which the spin remains constant unless acted on by an external torque; in other words, the rotational speed is constant as long as the net torque is zero.
Moment of inertia of wheel , Iw = 5kg m2
Moment of inertia of inertia of person + stool, Ip =20kg
Initial angular speed fw = 4 rev/s
Initial angular speed, f = 0 rev/s
Final angular speed of wheel, fw' = 2 rev/s
Let, final angular speed of person + stool, f' = ?
From angular momentum conservation, we have the formula
Iw * fw + Ip * f = Iw * fw' + Ip * f'
That gives, 5 * 4 + 20 * 0 = 5 * 2 + 20 * f'
20 = 10 + 20 * f'

What is frequency?
The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to it as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed. The period is indeed the reciprocal of a frequency because it is the length of time for one cycle in a repeating event. When a heart beats 120 times per minute (2 hertz), for instance, the period (T), or space between beats, is half a second. In science and engineering, frequency is a crucial parameter for describing the temporal rate of change seen in oscillatory as well as periodic phenomena.
Let q and p represent the frequency of each allele, respectively.
If A and a have equal frequencies, then p = q = 0.5
because p + q = 1. The equation p2+2pq+q2 = 1
can be used because the population has been in
Hardy-Weinberg equilibrium.
As a result, the frequency of AA individuals is p2 = 0.52 = 0.25,
the frequency of Aa individuals is 2pq = 2 x 0.5 x 0.5 = 0.5,

In deep water, a wave is not really migrating but is transferring energy through the water in simple cyclic undulations. These are called waves of transition.
What is meant by waves of transition?Transitional waves are waves that move through water at a depth of 1/20 L D 1/2 L, which is less than half the wavelength but greater than one-twentieth the wavelength. Often wind-generated waves that have entered shallower water are transitional waves. The wave effect deformation begins at the specified beginning point and spreads over the mesh with rectilinear or circular wave fronts that are parallel to the X or Y axes.a wave that is accompanied by a significant net motion of the fluid, even if the wave moves more quickly than the fluid. Rivers have translator flood waves. A smaller group or subset of the Transition-related actions that must be carried out or accomplished before the Provider can provide the Services is referred to as the "Transition Wave."To learn more about waves of transition refer to:

the galactic distances used to measure the acceleration of the universe are determined by observations of question 6 options: a) trigonometric parallax b) hubble's law c) exploding white dwarfs (supernovae) d) cepheid variable stars
The galactic distances used to measure the acceleration of the universe are determined by observations of exploding white dwarfs (supernovae). Correct answer: letter C.
Because the brightness of a supernova is known very precisely. By measuring the brightness of a supernova, astronomers can calculate its distance from Earth. This allows them to measure the distance of far away galaxies and compare them over time to determine the acceleration of the universe.
What are white dwarfs?
White dwarfs are the dense, glowing remains of stars that have exhausted their nuclear fuel. These stars range in mass from about 0.6 to 1.4 times the mass of the Sun and are about the size of Earth. White dwarfs are some of the oldest stars in the universe, with lifespans of billions of years.

What happens to inflation and unemployment during a period of stagflation?.
The inflation rate will be high or increasing and unemployment will remains steadily high during a period of stagflation.
What is Inflation?Inflation can be described as the rate of increase in prices over a given period of time howver the Inflation serves as the broad measure, which can be seen in the overall increase in prices as well as the increase in the cost of living in a country.
It should be noted that in economics, stagflation can be regarded as the recession-inflation which is a case wheeby inflation rate is high or increasing, and in this case the economic growth rate slows, whereby the unemployment remains steadily high and thee will be a problem in the process of making economic policy, becvauise when trying to lower inflation may affect unemployment.
In conclusion, inflation rate will be high and in this case the unemployment will remains steadily high as a result of stagflation.

what will happen to the force needed to keep something in a circular path if the radius doubles while other variables stay the same?
The force doubles as it is directly proportional to the radius.
Does anything move faster when it follows a circular path?A shift in velocity can occur in either its magnitude (speed), its direction, or both. Even if the speed may be constant in uniform circular motion, there is always an accompanying acceleration since the direction of the velocity is continually changing.
What maintains the car's trajectory in a curve?Friction between the tyres and the road causes the centripetal force that causes the car to turn in a circular motion. If there isn't enough friction, the car will move in a curve with a larger radius and veer off the road.
