vibrations per second. Find ω
.
When a tuning fork for middle C has a frequency of 264 vibrations per second, the ω = 1658.76.
What is frequency?Frequency is the measure of how frequently an alternating current (AC) changes from positive to negative in a second. This switching doesn't occur in direct currents (DC). Frequency is measured in Hertz (Hz). For instance, if a current changes its sign 60 times per second, it is said to have a frequency of 60Hz.
An AC current's period is the time it takes for the voltage to start at zero (zero), go from positive to negative, and then go back to zero (zero). The period's reciprocal is the frequency. High frequency, in contrast to low frequency, has more waves per second and a shorter period. Low frequency, on the other hand, has fewer waves per second but a longer period.
We need to find the value of variable ω
We know that the motion has a frequency of [tex]\dfrac{\omega}{2 \pi}[/tex]
Thus, with a given frequency of 264 vibration per second we obtain :

(b) Calculate the depth of the sunken ocean liner. (c) Calculate the magnitude of the net force due to the fluid pressures only on a viewing port of the submarine at this depth if the viewing port has a surface area of 0.0100 m2 (d) What prevents the ‘net force’ found in part c from accelerating and moving the viewing port. . Suppose that the ocean liner came to rest at the surface of the ocean before it started to sink. Due to the resistance of the seawater, the sinking ocean liner then reached a terminal velocity of 10.0 m/s after falling for 30.0 s. (e) Determine the magnitude of the average acceleration of the ocean liner during this period of time. (f) Assuming the acceleration was constant, calculate the distance d below the surface at which the ocean liner reached this terminal velocity. (g) Calculate the time t it took the ocean liner to sink from the surface to the bottom of the ocean.
(a)Gauge pressure is 412 atmospheres ; (b) depth = 4.24 x 10^2 m. (c)magnitude of the net force = 4.13 x 10^2 N. (d) viewing port is made of strong material that can withstand the high pressure (e)magnitude of the average acceleration = 0.333 m/s^2 (f) d=498.5m (g) t= 29.94 s.
What is gauge pressure?Gauge pressure is the pressure of a system above the atmospheric pressure.
(a) Since the inside of the submarine is kept at atmospheric pressure, gauge pressure on the sunken ocean liner is 413 atmospheres - 1 atmosphere = 412 atmospheres.
(b) P = ρgh, where P is pressure, ρ is density of seawater, g is acceleration due to gravity, and h is depth. Given P = 413 atmospheres, ρ = 1025 kg/m3, and g = 9.8 m/s^2. Therefore, h = P/(ρg) = 413 atmospheres / (1025 kg/m3 * 9.8 m/s^2) = 4.24 x 10^2 m.
(c) As, F = PA, where F is force, P is pressure, and A is area. Given, P = 413 atmospheres and A = 0.0100 m^2. So, F = PA = 413 atmospheres * 0.0100 m^2 = 4.13 x 10^2 N.
(d) The viewing port is made of a strong material like glass or acrylic that can withstand the high pressure of the surrounding seawater.
(e) As, v = at, where v is final velocity, a is acceleration, and t is time. We know that v = 10.0 m/s and t = 30.0 s. So, a = v/t = 10.0 m/s / 30.0 s = 0.333 m/s^2
(f) d = 1/2at^2 to find the distance. d = 1/20.333*30^2 = 498.5m
(g) v^2 = u^2 + 2as, where u is initial velocity, v is final velocity, a is acceleration and s is distance. s = (10^2 - 0^2)/(2*0.333) = 299.4 m. So, time t = s/v = 299.4/10 = 29.94 s.

a.) Third charge is placed so that the net force becomes zero:0.8620 m
b.) Both charges are positive: 0.1092 m
Define the term coulombs law?Coulomb listed the following characteristics of the electric force given charges in a resting state: Unlike charges attract each other whereas like charges repel one another.As a result, a positive charge pulls a negative charge toward it whereas two negatively charged ions repel one another. The line here between two charges is where the attraction and repulsion occurs.The stated data:
Q1 = 5.00 μC Q2 = -3.00 μCLet the third charge be 'Q3' such that (net force acting on Q3 = 0)
Let distance between Q1 and Q2 br 'd' = 0.250 m
Let Q3 be at a distance x to of right of Q2.
Distance between Q3 and Q1: d + x
The distance at which the third charge must be positioned for the net force to be zero is specified.
k|Q1||Q3|/(d+x)² = k|Q2||Q3|/(x)²
Write in terms of 'x'.
x = d/±√((|Q1|/|Q2|) - 1)
Put values:
x = 0.250/±√((|5|/|-3|) - 1)
x = 0.250/±√((5/3) - 1
x = 0.250/(±1.290 - 1)
x = 0.250/(1.290 - 1) or 0.250/(-1.290 - 1)
x = 0.8620 or −0.1092
AS, x can not be negative.
So, x = 0.8620

The kinetic energy increases by equal amounts over equaldistances.
The true statement concerning this situation is the total energy of the block increases by equal amounts over equal distances
What is the velocity of the block at the moment it hits the ground?The velocity of the block when it hits the ground depends on several factors, such as the initial height of the tower, the mass of the block, and air resistance. In the absence of air resistance, the velocity of the block at the moment it hits the ground is equal to the square root of twice the acceleration of gravity multiplied by the height from which it was dropped. Since the acceleration of gravity is approximately 9.81 meters per second squared, the velocity of the block at the moment it hits the ground can be calculated as follows:Velocity = √2 * 9.81 * HeightFor example, if the block was initially dropped from a height of 100 meters, its velocity at the moment it hits the ground would be approximately 44.3 meters per second. However, if the block is falling through air, the velocity may be slightly lower due to air resistance. Air resistance is a force that acts in the opposite direction to the motion of the block, reducing its velocity over time. The magnitude of air resistance depends on the size and shape of the block, as well as its velocity. If the block is falling at a high velocity and has a large surface area, air resistance can be quite substantial.To learn more about acceleration of gravity refer to:

looking at the plot, i determined that the explorer 35's orbit is 11,400 km* across its long dimension. use this distance to find the orbit's semimajor axis in kilometers.
The semimajor axis of Explorer 35's orbit is 5,700 km. The semimajor axis of Explorer 35's orbit is half the long dimension of 11,400 km.
What is orbit's semimajor axis?The semimajor axis of an orbit is the longest radius of the ellipse that is described by the orbit. It is also half of the sum of the periapsis and apoapsis distances. The semimajor axis can be used to calculate the orbital period of an object in an orbit around a given primary body. For example, for an object in a circular orbit around a star, the orbital period can be calculated as T = 2π√a^3/μ, where a is the semimajor axis and μ is the standard gravitational parameter of the star. The semimajor axis is also used to calculate the energy of an object in orbit around a given primary body. For a two-body system, the energy of the object can be calculated as E = -μ/2a, where a is the semimajor axis and μ is the standard gravitational parameter of the primary body. The semimajor axis can also be used to calculate the angular momentum of an object in orbit around a given primary body. For a two-body system, the angular momentum of the object can be calculated as L = μa^2, where a is the semimajor axis and μ is the standard gravitational parameter of the primary body.To learn more about semimajor axis refer to:

O work done on the bob by gravity is positive O work done on the bob by gravity is negative O work done on the bob by gravity is zero
A pendulum bob swings from point A to point B along the circular arc indicated that
a. Work done is positive
b . Work done is ZERO ( because the string force(tension) is always perpendicular to the motion
Work done in physics is the energy that is transferred to or from an item when a force is applied along a displacement. For a constant force acting in the same direction as the motion, the work is simply equal to the product of the force's magnitude and the distance traveled. When a force is applied, it is said to have a component that moves the point of application, or it is said to have positive work. If the component of a force at the point of application is in the opposite direction of the displacement, the force is said to do negative work.

Choose a factor that would impact speed, velocity, or acceleration in a scenario presented by your peer.
Describe the impact that the factor has on the speed, velocity, and acceleration.
Traffic will slow us down, and turning will reduce our velocity. Stops will slow acceleration, and traffic will slow it down. Acceleration or deceleration will also affect velocity.
While turning, acceleration is also affected (centripetal acceleration). You made an excellent choice of the discussion topic.
In physics, velocity is defined as a vector measurement of the motion's direction and rate. To be more specific, an object's velocity can be defined as the rate of change in the object's position corresponding to a frame of reference and time. Simply put, velocity describes the rate at which an object moves in a specific direction. It determines how fast or slow something is moving. Consider the case of two moving objects. If both objects are moving in the same direction, determining which one is moving faster is simple. Velocity is a vector measure of an object's rate of motion.

The change in momentum for each marble is −0.061m/s and the change in kinetic energy for each marble is −0.14m/s.
In physics, what is a momentum?
Momentum is characterised as the intensity of a body's motion.
As momentum depends on both velocity and the orientation of the body's motion, it is quantified by "mass velocity". Since speed is a vector and mass is a scalar, momentum is a vector. Mass times speed equals momentum.
What is the momentum unit in a formula?
Momentum. The momentum of an object is defined as its formas by its speed if it has a mass of m and a velocity of v. mv = momentum Momentum is a vector quantity since it has either magnitude and direction. Newton seconds, abbreviated N s, or kg m s 1 are the units of momentum.

A human body is made mostly of water, which has a density of 1000 kg/m^3. A women weighs 123 pounds. 1 kg of her mass weighs about 2.2 pounds.
What is the approximate volume of the woman's body, in units of m^3??
V= ......m^3
The approximate volume of the woman's body is 55.9 m^3.
How to calculate volume using density and mass in the unit of m^3?To calculate the volume of a substance using density and mass in the unit of m^3, the following equation must be used: Volume = Mass/Density. The mass of the substance must be known, as well as the density. Density is the mass per unit volume, so the density of the substance must also be known.The mass of the substance is typically measured in kilograms (kg). The density of the substance is usually measured in kilograms per cubic meter (kg/m^3). Thus, to calculate the volume in m^3, the mass must first be divided by the density of the substance.For example, if the mass of a substance is 10 kg and its density is 2 kg/m^3, then the volume of the substance can be calculated by dividing 10 kg by 2 kg/m^3. This gives a result of 5 m^3. In conclusion, to calculate the volume of a substance using density and mass in the unit of m^3, the mass must be divided by the density of the substance. The mass of the substance is typically measured in kilograms and the density is usually measured in kilograms per cubic meter.To learn more about density refer to:
