A rock is dropped from a 134-m-high cliff. how long does it take to fall (a) the first 67.0 m and (b) the second 67.0 m?

Answers

Answer 1

The time taken by the rock to travel another 67m is 1.5 s.

Briefing :

Taking +y direction downward and y₀= 0, we have y = V₀t+1/2 gt², which (with V₀≠0) yields t= [tex]\sqrt{\frac{2y}{g(a)} }[/tex]

(a) For this part of motion, y₁ = 67m, so that

                           t₁ = [tex]\sqrt{\frac{2(67)}{9.8 m/s^{2} } }[/tex] = 3.7 s

(b) For this next part of motion. we note that the total displacement is

                      y₂= 134m

Therefore, the total time is t₂ = [tex]\sqrt{\frac{2(134)}{9.8m/s^{2} } }[/tex] = 5.2 s

The difference between this and the answer to part (a) is the time required to fall through that second 67m distance:

Δt = t₂-t₁ = 5.2s - 3.7s = 1.5s

Therefore the time taken by the rock to travel another 67m is 1.5 s.

Gravity causes a body to descend faster, and as it does, the air resistance that slows it down rises. This keeps happening until the weight of the object and the force of air resistance are equal.

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

What do you mean by time?

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.

What is Acceleration ?

Acceleration can be defined as the rate of change of velocity. It is a vector quantity.

Given that a plane accelerates from rest at a constant rate of 5.0 m/s² along a runway that is 1800 mm long. Assume that the plane reaches the required takeoff velocity at the end of the runway.

What would happen if you applied a force that was smaller than the object's mass?

In order to accelerate a heavier (more massive) item in motion, more force must be exerted. When two objects are subjected to the same force, the smaller mass item will change speeds more quickly.

An item can alter its size or shape, begin moving, stop moving, accelerate, or decelerate as a result of a force acting on it. When two things contact, they exert pressures on one another that are identical in size but directed in the opposite direction

Answers

The average acceleration of the car as it accelerates from 15 m/s to 25 m/s will be 2.5 m/s².

What is Average acceleration?

Average acceleration is the average rate of change of velocity with respect to time. Mathematically -

a = Δv/Δt

Given that a car is traveling at 15 m/s in north direction and in 4 seconds it accelerates to 25 m/s in the north direction only. Therefore, we can write -

initial velocity [u] = 15 m/s

final velocity [v] = 25 m/s

time taken [Δt] = 4 s

The magnitude of the average acceleration can be calculated as follows-

a = Δv/Δt

Δv = v - u = 25 - 15

Δv = 10 m/s

a = 10/4

a = 2.5 m/s².

Neurons have a net negative charge when it is at rest. This means that when they are well active, they must have a positive charge.

At rest, neurons have a net negative charge; the inside of neurons is approximately 70 millivolts more negative than the outside. When neurons are active, they must be positively charged in order to generate an action potential.

Neurons have a strong negative charge within them, as opposed to a positive charge outside. This is due to the presence of other molecules known as anions. They are negatively charged but far too large to escape through any available channel. They remain in place and give the cell a negative charge on the inside.

Because of an unequal distribution of positive ions across the membrane, the resting potential is negative; 3 Na+ is pumped out of the cell for every 2 K+ that enters, so the inside of the cell is less negative (less positive) than its surroundings.

Total internal reflection (TIR) is an optical phenomenon when waves arriving at the interface (boundary) of two media, such as water and air, are entirely reflected back into the first (internal) medium rather than being refracted into the second (external). It happens when the waves are incident on the interface at a suitably oblique angle and the second medium has a higher wave speed (i.e., lower refractive index) than the first. TIR occurs not only with electromagnetic waves like light and microwaves but also with other types of waves, including sound and water waves.

[tex]Q_{c}[/tex] =  257 j

[tex]Q_{h}[/tex] =  465 j

Therefore from above equation can be find the value of work input by the refrigerator in each cycle,

[tex]W[/tex] =[tex]Q_{h}[/tex] - [tex]Q_{c}[/tex]

w = (465 j) -(257 j)

w= 208j

A car can go from 0 to 60 mph in 6.0 s .assuming that it could maintain the same acceleration at higher speeds, how long would it take the car to go from 0 to 120 mph?

Answers

The time taken for the  car to reach 120 mph speed is 12 seconds.

Acceleration of the car

The acceleration of the car is the rate of change of velocity of the car with time.

a = Δv/t

where;

t is time = 6 s

a = (60 mph) / (6 s)

when the speed increases to 120 mph

The time of motion at the given constant speed is calculated as follows;

t = v/a

t = (120 mph) / (60 mph / 6s)

t = (120 mph x 6 s) / (60 mph)

t = 2 x 6 s

t = 12 seconds

Thus, the time taken for the  car to reach 120 mph speed is 12 seconds.
