The new acceleration of the rocket is equal to 3.72 g.
What is acceleration?Acceleration can be demonstrated as the rate of change of velocity of a body with respect to time. The acceleration of a body can be defined as a vector quantity and can also be expressed as the second derivative of position w.r.t. time.
According to Newton's 2nd law of motion, the force acting on an object is equal to the multiplication of the mass of an object and acceleration.
F = ma
And, a = F/m
Therefore, the acceleration of a given body is inversely proportional to the body's mass.
Given, the new force exerted by the rocket, Fnew = 46,458 N
The old force exerted by the rocket, Fold = 12,482 N
The ratio of forces:
[tex]\displaystyle \frac{F_{new}}{F_{old}} =\frac{46458}{12482} = 3.72[/tex]
[tex]\displaystyle \frac{a_{new}}{a_{old}} = 3.72[/tex]
[tex]\displaystyle {a_{new}} = 3.72\times {a_{old}}[/tex]

An electron is ejected from the cathode by a photon with an energy slightly greater than the work function of the cathode. How will the final kinetic energy of the electron upon reaching the anode compare to its initial potential energy immediately after it has been ejected?.
It will be approximately equal.
How will the final kinetic energy change?We can infer that all of the energy in the electron is Potential energy (PE) because the energy provided by the photon is hardly enough to outweigh the work function.
It will gain kinetic energy (KE) as it advances in the direction of the anode because it is moving through an electric field. All of the PE will have been transformed to KE by the time it reaches the anode.
According to the question
K = hf - W
W = Work function
The energy of photons is comparable. After conversion, there was only a little amount of KE remaining.
Therefore, PE (W) essentially equals KE (K).

A stretched string is observed to have four equal segments in a standing wave driven at a frequency of 480 hz. what driving frequency will set up a standing wave with five equal segments?
600Hz is the driving frequency needed to create a standing wave with five equal segments.
To find the answer, we have to know about the fundamental frequency.
How to find the driving frequency?The following expression can be used to relate the fundamental frequency to the driving frequency;f(n) = n * f (1)
where, f(1) denotes the fundamental frequency and the driving frequency f(n).
The standing wave has four equal segments, hence with n=4 and f(n)=4, we may calculate the fundamental frequency.f(4) = 4× f (1)
480 = 4× f(1)
f(1) = 480/4 =120Hz.
So, 120Hz is the fundamental frequency.
To determine the driving frequency necessary to create a standing wave with five equally spaced peaks? For, n = 5,f(n) = n 120Hz,
f(5) = 5×120Hz=600Hz.

It is given that in a wire simulation, we have to adjust only the length of the resistor.
It required to find the effect on resistor when adjust only the length of the resistor.
What happens to resistor when adjust only the length of the resistor?As we know that the length is directly proportional to the resistance of the wire that means is we increase the size or length of the wire then it also increase the resistance present in the wire. On the other hand if we decrease the length of the wire, it will decrease the resistance. This can be represented as:

When the wave speed increases the wave stay the same to get the same standing wave pattern
Standing wave are the combination of two waves moving in opposite directions . Amplitude of both the waves is same and frequency is also same . The phenomenon is the result of interference
Wavelength and frequency are inversely related to each other .
frequency = c / wavelength
so if one get change then the other changes. As one get decrease other will increase and vise versa. . The speed of the wave depends on the medium. Change in the frequency of the wave changes its form to go into the next harmonic so the wavelength changes .Also in order to maintain the wave pattern the wavelength remain same

Stellar nurseries, such as the orion nebula, contain hundreds or more fragmenting and contracting regions, as well as many protostars and stars. What condition would allow a protostar to become a stable star?.
The hydrogen fusion process will begin after the protostar reaches a temperature of 10 million degrees kelvin, and it will then turn into a stable star.
How does a protostar become a stable star?The interstellar medium can sometimes be gathered into a large nebula, which is a cloud of gas and dust. A nebula can span a number of light years. These nebulae are where gas and dust can combine to produce stars. Until a star can combine hydrogen into helium, it cannot be considered a star. They are referred to as protostars before then. As gravity starts to gather the gases into a ball, a protostar is created. Accrution is the term for this procedure.
Gravitational energy starts to heat the gasses as gravity draws them into the ball's core, which causes the gasses to radiate radiation. Radiation initially just dissipates into space. However, much of the radiation is retained inside the protostar as it draws in stuff and becomes denser, which causes the protostar to heat up even more quickly.

Direction of |a+b| is south east (|2i - 6j|, this shows 2 units to the right and 6 units down)
Direction of |a-b| is north east (|4i + 2j|, this shows 4 units right & 2 units up)

Which best explains the forces acting on the objects?
Objects W and X have balanced forces, and objects Y and Z have unbalanced forces.
Objects W and Y have balanced forces, and objects X and Z have unbalanced forces.
Objects X and Y have balanced forces, and objects W and Z have unbalanced forces.
Objects X and Z have balanced forces, and objects W and Y have unbalanced forces.
The option that best explains the forces acting on the objects is that option b. Objects W and Y have balanced forces, and objects X and Z have unbalanced forces.
How do you know if forces are balanced or unbalanced?When the motion of an object is said to be altered, the forces are known to be in a sate that is seen as unbalanced.
Note that Balanced forces are said to be one that are equal in size and also opposite in direction.
Hence, if forces are balanced, there is no alteration in motion and it is seen in cases if a person is pushed or pulled on an object that is seen from opposite directions but also has the same force.
Therefore, The option that best talks about the forces acting on the objects is that option b. Objects W and Y have balanced forces, and objects X and Z have unbalanced forces as it does better justice to it.

Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same. (hint: look back in the lesson under the section title ""resistance"")
The light bulb would glow brighter.
What is Resistance?
a force that works against a body's direction of motion and seeks to stop or slow down motion, such as friction. a measure of how much a material prevents an electric current from flowing as a result of a voltage.
What is the law of resistance?
Resistance and Ohm's Law. According to Ohm's law, the resistance of the circuit and the current or energy travelling through the resistance are both exactly proportional to the voltage or potential difference between two places.
The current would grow since it is exactly proportionate to the voltage, increasing the light bulb's brilliance, or simply making it brighter.

When you have two of the same charges along a horizontal line, where is the electric field the greatest? is there ever a point where the field will be zero?
When you have two of the same charges along a horizontal line, The electrical field is the greatest the closest it is to the charges. And there will be a zero charge in between the two like charges.
Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge.
The formula of electric field is given as;
E = F /Q
Where,
E is the electric field.
F is a force.
Q is the charge.
The electrical field is the greatest the closest it is to the charges because there will be high electric strength and electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart. Also , there will be a zero charge in between the two like charges.
