Flag what horizontally applied force will accelerate a 400 kg crate at 1m/s2 across a factory floor against a friction force half its weight?

A ship travels 20 km to the south and then 40 km to the west. The ship's displacement from its starting point is approximately 44.7 km. Hence, the displacement is approximately 45 km.

Here, the calculation is done,

a = 20 km (southward movement)

b = 40 km (westward movement)

Now, one can find the displacement (d) using the Pythagorean theorem:

d² = a² + b²

d² = (20 km)² + (40 km)²

d² = 400 km² + 1600 km²

d² = 2000 km²

Now, by taking the square root of both sides to find the displacement (d):

d = √(2000 km²) d ≈ 44.7 km (rounded to one decimal place)

So, the ship's displacement from its starting point is approximately 44.7 km.

Hence, the displacement is approximately 45 km.

For customer arrivals, the random number interval assigned to the time between arrivals of 2 minutes is 0.0500-0.19999.

Time is the continued sequence of the existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of the various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with the three spatial dimensions.

Time has long been an important subject of the study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.

Time in physics is operationally defined as the "what a clock reads".

The physical nature of the time is addressed by general relativity with respect to events in spacetime. Examples of events are collision of two particles, the explosion of a supernova, or the arrival of a rocket ship. Every event can be assigned the four numbers representing its time and position (the event's coordinates).

However, the numerical values are different for the different observers. In general relativity, question of what time it is now only has meaning relative to a particular observer. Distance and the time are intimately related, and the time required for light to travel a specific distance is the same for all observers, as first publicly demonstrated by Michelson and Morley. General relativity does not address nature of time for extremely small intervals where quantum mechanics holds. At this time, there is no generally accepted theory of the quantum general relativity.

The correct answer for the ratio of the period of object a to the period of object b 4.

we know time for one revolution. around which is the period for one revolution it has to travel distance equal to perimeter.

So, speed of object in circular motion

v = perimeter /t

time period = 2πr/v

for object A ,Ta = 2 π R/ v

for abject B, Tb = (2π R/2 )/2v

now Ta / Tb = ((2πR)/v)/((2π(R/2))/(2V)) = 1/(1/4) = 4

Circular motion is defined in physics as the movement of an object around the circumference of a circle or the rotation of an object along a circular path. It can be uniform, with a constant angular rate of rotation and speed, or non-uniform, with a variable rate of rotation.When the magnitude of an object's velocity in uniform circular motion is v, the velocity is equal to the circumference C of the circle divided by the period. As a result, V = fracCT. The circumference of a circle is equal to pi multiplied by R. So, C = 2Π R.

The correct answer for the affect in the stage capacity is that it will increase.

The stage's capacity will increase .

The capacity formula is as follows:

Capacity = (Batch size) / (Total setup time + processing time x batch size) 

Clearly, increasing the batch size twice will increase capacity, but not in the same proportion because the batch size is the same in the numerator and denominator. Increasing the batch size will increase the capacity but in very small proportions. Furthermore, if the batch size is too large, goods will be produced even if there is no demand, and if the batch size is too small, capacity will be lost. As a result, there is a trade-off between batch size and capacity.

However, the atmospheric pressure and density are essentially the same at the peak and bottom of the falls. Therefore,

v^2/2 + gz = constant , so:

v_bottom^2/ 2 = v_top^2/2 + gz, or:

v_bottom = sqrt(v_top^2 + 2gz) = sqrt(v_top^2 + 2g*170)

Answer:

A mature star is a star that has exhausted its supply of hydrogen

Explanation:

For the most part, a star is powered by nuclear fusion. The energy is first produced by the fusion of hydrogen atoms in the core of a main-sequence star. Later, when the helium predominates in the core, stars like the Sun begin to fuse hydrogen along a spherical shell around the core. This allows the star to steadily increase in size, passing through the subgiant stage and eventually reaching the red giant stage.

When they reach this stage, the hydrogen in them nearly completely depletes, and they get brighter and hotter, eventually becoming low-mass white dwarfs.

When a star's supply of hydrogen in its core runs out, leaving only helium, the outward force provided by fusion begins to diminish, and the star can no longer maintain equilibrium. When the force of gravity exceeds the force of internal pressure, the star begins to disintegrate. The outcome of this collapse is determined by the mass of the star.

We have to integrate the specified acceleration vector to obtain the velocity vector of the particle before integrating the velocity vector to obtain the position vector of the particle.

So, the acceleration vector: a(t) = 6i + 3j

We will the find the velocity vector,

To find the velocity vector, we integrate the acceleration vector with respect to time 't':

∫a(t) dt = ∫(6i + 3j) dt

when we integrate with respect to time 't' that gives us:

v(t) = 6t i + 3t j + C

where 'C' is the constant of integration.

Using the initial velocity condition to find 'C':

Given initial velocity: v(0) = k

Substitute t = 0 into the velocity vector equation:

v(0) = 6(0) i + 3(0) j + C

k = C

So, C = k

We put the value of 'C' back into the velocity vector equation:

v(t) = 6t i + 3t j + k

Calculate the position vector r(t):

To find the position vector, we integrate the velocity vector with respect to time 't':

∫v(t) dt = ∫(6t i + 3t j + k) dt

Integrating with respect to time 't' gives us:

r(t) = [tex]\rm 3t^2 i + (3/2)t^2 j + kt + D[/tex]

where 'D' is the constant of integration.

We use the initial position condition to find 'D':

Given initial position: r(0) = i

Substitute t = 0 into the position vector equation:

r(0) = [tex]\rm 3(0)^2 i + (3/2)(0)^2 j[/tex]+ k(0) + D

i = D

So, D = i

when we put the value of 'D' back into the position vector equation:

It's common to refer to photons as energy packets. This analogy is excellent because a photon has uncondensable energy. An alternating electric field is how this energy is kept in reserve. The universe's size, which is the longest theoretical wavelength of light, and the Planck length, which some theories claim to be the smallest, have never been measured.
