If we assume at time instance t= 0, then the same thing happens. initial velocity is equal to final velocity

During a free fall, only the gravitational force acts on a body. The initial velocity of the body is zero during free fall.

Vertical motion is symmetrical - the distance and time are the same in the rise as in the fall; the final velocity will have the same magnitude as the initial velocity but in the opposite direction. Horizontal components will never be effected by gravity; it is constant velocity motion

The average velocity is the ratio of the total distance traveled to the total time taken. This can happen in two cases, first if the initial velocity and the final velocity are equal to the average velocity and there is no change in the velocity for the entire trip

Velocity is the measure of the amount of distance an object covers in a given amount of time. Here's a word equation that expresses the relationship between distance, velocity and time: Velocity equals distance travelled divided by the time it takes to get there.

Answer:

When two objects collide, the forces that are exerted on each other are determined by their masses and speeds. If the mass of one of the objects is increased, the force that it exerts on the other object during the collision will also increase. Similarly, if the speed of one of the objects is increased, the force that it exerts on the other object during the collision will also increase. In general, the greater the mass and speed of an object, the greater the force that it will exert on another object during a collision. However, it is important to note that the direction of the forces will remain the same, regardless of the masses or speeds of the objects involved.

If you placed 1.00 coulomb (C) of positive charge on the Earth and 1 C of negative charge 384,500 km away on the Moon, the positive charge on the Earth would experience a gravitational force of attraction towards the negative charge on the Moon.

The gravitational force of attraction between two charged particles is given by the formula:

where F is the gravitational force, k is the Coulomb constant, q1 and q2 are the charges of the two particles, and r is the distance between them.

Plugging in the values provided, we get:

F = (8.99 x 10^9 N*m^2/C^2) * (1 C) * (1 C) / (384,500 km)^2

Answer:

Scientific theories are attempts to explain how events occur in the natural world.

Explanation:

A scientific theory is an explanation for a wide range of observations and phenomena that have been tested and supported by multiple lines of evidence. A theory is not based on a single piece of evidence, but rather on a collection of evidence that has been accumulated over time through careful observation and experimentation.

Scientific theories are based on facts, which are observations of events in the natural world. However, a theory goes beyond simply describing these events; it seeks to explain why and how they occur. For example, the theory of evolution explains how organisms have evolved over time through natural selection. It is based on a wide range of evidence, including observations of the fossil record, comparative anatomy, and molecular biology, among others.

Overall, scientific theories are important tools for understanding and explaining the natural world, and they are constantly being revised and updated as new evidence becomes available.

The spring constant of the spring is 7.497 N/m.

The given parameters;

mass of the block, m = 0.482 kg

additional extension, = 0.338 m

The spring constant of the spring is calculated as follow

F = mg

Kx = mg

K = mg/x

K = 0.482 × 9.8 / 0.630 = 7.497N/m

F = -kx.

The spring constant, or k, is the proportional constant. It is a gauge of the spring's rigidity. A spring exerts a force F = -kx in the direction of its equilibrium position when it is stretched or compressed to a length that deviates by an amount x from its equilibrium length. The spring constant is calculated by dividing the force required to extend or compress a spring by the length it goes up or down. It is used to assess the stability or instability of a spring, The spring's stiffness is quantified by the spring constant, or k. For various springs and materials, it differs.

The period of motion is simple hormonic motion and the maximum speed of the particle is 0.0031s

(a) Simple harmonic motion is defined as "the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law (F=-Kx). The motion experimented by the particle is sinusoidal in time and demonstrates a single resonant frequency".

(b) The equation that describes the simple harmonic motion is given by =

= X = Acos(ωt + θ)     [1]

And taking the first and second derivate of the equation (1) we obtain the velocity and acceleration function respectively.

For the velocity:

= V = dx/dt = -Aωsin(ωt + θ)        [2]

For the acceleration:

= A = dv/dt =  -Aω²cos(ωt + θ)           [3]

As we can see in equation [3] the acceleration would be maximum when the cosine term would be -1 and on this case:

= Aω² = 8x10³ m/s²

Since we know the amplitude A=0.002m  we can solve for ω like this:

= ω = √ (8000/0.002)

(b) The longest wavelength in the emission spectrum of the hydrogen atoms corresponds to the transition between the lowest energy levels in the atom. In the case of hydrogen, the ground state is the lowest energy level, so the longest wavelength would correspond to a transition from an excited state to the ground state.

(c) The portion of the electromagnetic spectrum to which the longest wavelength belongs depends on the specific value of the wavelength. The electromagnetic spectrum includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

(d) The series to which the longest wavelength belongs can be determined by the values of the energy levels involved in the transition. In the case of hydrogen, there are three series: the Lyman series, the Balmer series, and the Paschen series. The Lyman series corresponds to transitions from higher energy levels to the ground state, the Balmer series corresponds to transitions from intermediate energy levels to the ground state, and the Paschen series corresponds to transitions from lower energy levels to the ground state.

The bug's maximal kinetic energy changes as 16 times of Kinetic energy before amplitude increases when the amplitude approaches 0.20 mm.

The amplitude of a wave is its largest displacement. The wave's greatest velocity is now expressed as its amplitude, which is: v =Aw= K/M.

Now, the square of the wave is directly proportional to the kinetic energy of a system. As a result, the wave's maximum kinetic energy is given by KE = k/2A^2, which means that

KE1/KE2 = A1^2/A2^2 where KE1 is the kinetic energy prior to the amplitude (A1) increasing and KE2 is the kinetic energy following the amplitude increasing (A2)

Due to that,

The bug's entire vertical journey was S = 0.10m

The wave's amplitude is equal to half of the whole distance from the top to the bottom, hence its value is (A) = S/2 = 0.1/2 = 0.05m.

Now that the wave's amplitude has increased to 0.20 m, KEA = KE1/KE2 = A1^2/A2^2

KE1/KE2 = (0.05)^2/(0.20)^2, which equals 0.0025/0.04 = 0.0625.
