Answer:

Terminal velocity occurs when the frictional force of air counteracts the gravitational force of gravity.

In Second image, Both forces are equal and therefore is the correct answer

Explanation

Step 1

Diagram:

Step 2

the work done by an object is defined as:

the product of the displacement of an object and the component of the applied force which is in the direction of the object's displacement:

so,let

therefore,l to reduce the amount of force needed , we need to affect the distnace or the angle

Step 3

let's check every option

A)Make the ramp higher.

as the distnace becomes greater the force must increase too, so this is not the rigth option,in other words , a higher distnace will neeed a stronger force

B)making the ramp longer will make the angle becomes smaller, and this makes the distance becomes greater,

C) when yuo make the ramp shorter ,you will need the same force because the displacementis vertical

when the angle becomes smaller, the work will be the same, but the distnace and force, change, cos

when the angle goes to 0° degrees the required force becomes smaller, so

the answer is

b. Make the ramp longer.

D)finally, if yuo lift the object witouth the ramp ( vertically) , the distnace becomes smaller, ( only 3 m),but the force is the total weigth of the object ( 300 N)

Distance between canyon wall and the person who hear the echo after 2.29 seconds is 786.23 meter.

An echo is a sound that is partially or completely repeated as a result of REFLECTION. REVERBERATION is a type of reflected sound, although in this instance, it is impossible to tell apart individual repetitions of the original sound. They are also used in SONAR (Sound navigation and ranging) and RADAR(Radio detection and ranging).

Given that in the question it takes 2.29 seconds to reach the person speed of sound in air is 343.33 m/s, so the distance between the person and the source of sound canyon is 786.23 m.

786.23 m  far away from a canyon wall are if it takes 2.29 seconds to hear echo.

If you are dividing an objects distance traveled by its speed, you are calculating its Time of travel.

What is Time of travel?
Time travel is the idea of moving between certain moments in time, similar to moving between various points in space by a person or an object, usually with the use of a fictitious machine called a time machine. The idea of time travel is well known in philosophy and literature, especially science fiction. H. G. Wells' 1895 book The Time Machine popularised the concept of a time machine. It is unknown whether going back in time is physically possible, and if it is, there may be causality issues that arise. It has been widely seen and is generally understood within the context of special relativity and general relativity to be possible to move through time in the opposite direction from how we typically perceive it.

Answer:

9.68 seconds

Explanation:

To answer the question, we will use the following equation for the uniformly accelerated motion:

Where x is the distance travel by the object, v0 is the initial velocity, a is the acceleration and t is the time.

Since, the man drops his screwdriver, x = 1500 ft, v0 = 0 ft/s and a = -32 ft/s².

Then, replacing the values, we get:

Then, solving for t, we get:

Therefore, the screwdriver takes 9.68 seconds to hit the ground.

Q = m x c x ΔT

Where:

Q= heat

m= mass

c = specific heat capacity

The following is a strategy for encoding a message that is gesturing.

The communication process begins when a sender or sender selects words symbols images, etc. to represent the message to be conveyed to the recipient. This process known as encoding involves putting thoughts ideas, or information into symbolic form. Coding is the process of transforming thoughts into communication. Encoders use the medium to send messages phone calls emails text messages face-to-face meetings, or other means of communication.

There are varying levels of conscious thought in encoding messages. Encoding and decoding a message is the process of first converting the original text into a random meaningless text called ciphertext. This process is called encoding. Decryption is the process of converting this ciphertext back to the original text. This process is also called the encryption-decryption process.

[tex]S = 4\times17 + \frac{1}{2}(0)17^2[/tex]

S = 68 m

The acceleration is positive when the object is speeding up and negative when speeding down. According to Newton’s Second Law, the net unbalanced force which acts on the object causes this to happen. Thus, it can be said that acceleration is a vector quantity. It is so because it changes the time rate of change of velocity.

Justin Beiber (mass 60kg) fell off a 108m cliff and landed in the sea. The velocity of him when he was going when he hit the water is (V)=46.08 m/s.

Velocity is a term of physics that is used to decide the value of object's covered distance in a constant time. It can be measured in m/s and cm/s.

To calculate the velocity we are using the formula here is, v²-u²=2gh

Here we are given,

u= The initial velocity of Justin Beiber = 0 m/s.

g= The acceleration due to gravity. = 9.8 m/s².

h= The height of the cliff. = 108m.

We have to calculate the final velocity of Justin Beiber = v.

Now we put the values in above equation, we get,

v²-u²=2gh

Or, v²-(0)²=2*9.8*108

Or, v²=2116.8

Or, v=46.008 m/s
