Answer:
Contact forces can be classified according to six types: tensional, spring, normal reaction, friction, air friction, and weight. Noncontact forces: Forces that take place when two objects do not touch. These forces can be classified according to three types: gravitational, electrical, and magnetic.

What is the speed of an object that travels 60 meters in 4 seconds?
a) 240 m/s
b) 15 m/s
c) 0.067 m/s
d) 15 mph
Answer:
B) 15 m/s
Explanation:
Since most of the answer choices are in m/s, you can try dividing 60 meters/4 seconds in order to get the seconds on the bottom to become 1 second.
You want to find how many meters the object can travel in 1 second, rather than 4 seconds.
[tex]\frac{60 \ m}{4 \ s} \div \frac{4}{4} = \frac{15 \ m}{1 \ s}[/tex]Now you can see that for every 1 second of time, the object can travel 15 meters. This corresponds to answer choice B) 15 m/s.
The last option, D, is incorrect because we are not dealing with hours as our unit of time. We are dealing with seconds.
Answer:
b) 15 m/s
hope it help you

How Can the human ear detect the sound
Answer:
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.
Explanation:
The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

When performing a standard push-up, our hands should be placed on the ground... as close together as possible to make it the most challenging as close together as possible to make it the most challenging really wide to focus on chest development really wide to focus on chest development just outside our shoulders
Answer:
Kindly check the explanation section.
Explanation:
The statement given in the question or problem above is true or let's say it is correct. And the statement describes different kinds or types of push up.
Push up is a kind of excercise that is being done mainly to strengthen the arm and the cheat. The way one goes about it determines which part of the body one is strengthening.
The kind of push up in which one has to close up the gap between his or hands is known as the close push ups. This kind of push up strengthens the arm more than the other part of the body and the more one puts his or her hands closer the more problematic the push up excercise becomes.
Other types or kinds of push ups are the Slow Eccentric Push Ups, Wide Push Ups, Staggered Push Ups, T push ups, Fingertip Push Ups and many more.

how does shape of object affect friction
Answer:
There are three types of friction.
1. Slanting friction
2. Sliding friction
3. Rolling friction
In the first two types of friction, the body of the object will come in contact with the irregularities on the surface more than in the case of rolling friction, thus a heavy box in square shape will have more friction than a heavy-duty vehicle.
This is also the reason why all vehicles are having wheels as they reduce friction and makes transportation easier and many people suggest to use a small log of wood to be placed on the bottom of a heavy box with flat bottom so it can moved easily due to reduction of friction

why might a CD be a more reliable way to copy and distribute a sound recording than a vinyl record
Answer:
Is either b or d
Explanation:
A CD be a more reliable way to copy and distribute a sound recording than a vinyl record because a CD is easier to copy exactly over and over again.
What are CDs and vinyl records?CDs are digital music storage devices, which means the music is binary data encoded. It uses a 2-channel, 16-bit, 44.1 kHz configuration as the norm for CDs. A laser reads the data, and after it has been decoded, audio is played back.
A sensitive needle known as a stylus is used to read the physical record of the music that is imprinted on the vinyl disc because vinyl is an analogue storage medium. The 12-inch 33-rpm LP, 7-inch 33-rpm EP, and 7-inch 45-rpm single make up the typical vinyl album.
The diameter and playback speed are what determine a vinyl disc's storage capacity (larger discs and slower playback means more capacity). The stereo channels are divided among the groove's two sides.
Hence, option (D) is correct.

Answer: B. Elements
Explanation:
Most things we use everyday are compounds which are composed of two or more elements.
What are compounds?
Compound is defined as a chemical substance made up of identical molecules containing atoms from more than one type of chemical element.
Molecule consisting atoms of only one element is not called compound.It is transformed into new substances during chemical reactions. There are four major types of compounds depending on chemical bonding present in them.They are:
1)Molecular compounds where in atoms are joined by covalent bonds.
2) ionic compounds where atoms are joined by ionic bond.
3)Inter-metallic compounds where atoms are held by metallic bonds
4) co-ordination complexes where atoms are held by co-ordinate bonds.
They have a unique chemical structure held together by chemical bonds Compounds have different properties as those of elements because when a compound is formed the properties of the substance are totally altered.
