A coin rolls across the floor at an angular speed of 4 rotations per second. What is its speed in degrees persecond? Hint: One full rotation equals 360 degrees.

Answers

Answer 1

Answer:

Speed in degrees per second or angular speed will be 25.13 radian

What is an angular speed?

Angular speed is defined as the rate of change of angular displacement and can be expressed as angular rotation / time

Total number of rotations = 4

one rotation makes an angle of = 360° = 2 π radian

coil is rolling at an angular speed of 4 rotation / second

4 rotations will make = 2π * 4 = 25.13 radian

hence , speed in degrees per second or angular speed will be 25.13 radian

Answer 2

Answer: If there are 4 rotations per second and 360 degrees in 1 rotation, the angular speed is 1440 degrees per second. (4 * 360)

Usually angular speed is measured in radians though.

An atom of carbon (C) forms covalent bonds with two atoms of oxygen (O) to form carbon dioxide. How are the valence electrons of these atoms rearranged to form the bonds?A. Electrons are transferred from the carbon atom to the oxygen atoms.
B. Electrons are transferred from the oxygen atoms to the carbon atoms.
C. Many valence electrons are shared between the atoms.
D. A few valence electrons are shared between the atoms

Answers

Answer : The correct option is C.

Explanation :

Covalent bond : Covalent bond forms when two non-metal atom share a pair of electrons.

In the covalent bond formation of carbon dioxide, carbon and oxygen atom share four pair of electrons. The carbon atom joined by four covalent bonds to two oxygen atoms.

The valence electrons in carbon atom = 4

The valence electrons in two oxygen atom = 2(6) = 12

Therefore, these atoms are rearranged to form the bonds by the sharing of many valence electrons between the atoms.

The lewis-dot structure of carbon dioxide is shown below.

Which of the following is an SI base unit for measuring mass?Ampere
Gram
Meter
Pound

Answers

Among the option given below, the most appropriate SI base unit for measuring mass is Gram. Thus, the correct option is B.

What is an SI unit?

An SI unit may be defined as a form of the metric system that is utilized universally as a standard for measurements. It is an international system of units. The expanded form of the SI unit is Systeme International.

The exact SI base unit for measuring mass is the kilogram, kg. But it is not mentioned in the options. So, the most appropriate SI base unit for measuring mass is Gram.

Ampere is the SI base unit for measuring the electric current. A Meter (m) is the SI base unit for measuring length. A Pound is the international standard symbol used as a unit of mass and i.e. lb.

Therefore, among the option given below, the most appropriate SI base unit for measuring mass is Gram. Thus, the correct option is B.

The large blade of a helicopter is rotating in a horizontal circle. The length of the blade is 6.58 m, measured from its tip to the center of the circle. Find the ratio of the centripetal acceleration at the end of the blade to that which exists at a point located 4.78 m from the center of the circle.

Answers

Answer:1.37

Explanation:

Given

Length of Blade $L=6.58 m$

Let blades be rotating at an angular velocity of $\omega$

centripetal acceleration at any radial distance r is given by

$a_c=\omega ^2\cdot r$

at $r=6.58$

$a_c_1=\omega ^2\cdot 6.58$

at $r=4.78 m$

$a_c_2=\omega ^2\cdot 4.78$

thus $(a_c_2)/(a_c_1)=(\omega ^2\cdot 4.78)/(\omega ^2\cdot 6.58)$

$(a_c_2)/(a_c_1)=0.72$

$(a_c_1)/(a_c_2)=1.37$

Final answer:

Centripetal acceleration depends inversely on the radius. The ratio of the centripetal accelerations at the end of the blade and at 4.78m from the center is approximately 0.73.

Explanation:

The centripetal acceleration of an object moving in a circle of radius r is given by the formula ac = v²/r, where v is the tangential velocity of the object. In this scenario, the velocity at both points on the blade is the same, as the blade is rotating as a whole.

Therefore, the centripetal acceleration on the blade at any point is inversely proportional to the radius from the center of the circle to that point.

So, the ratio of the centripetal acceleration at the end of the blade (6.58 m from the center) to the centripetal acceleration at a point located 4.78 m from the center, is the inverse ratio of their distances from the center. Therefore, the ratio is 4.78/6.58 which approximately equals 0.73.

the four forces shown have the same strength. which force would be most effective in opening the door?

Answers

if the same forces are applied, then the door will not move due to similar strength. So, regardless the door won't move.

What are the types of force ?

Force is a parameter which can be defined as either pushing or pulling of the object resulting in the object’s interaction or movement, without force the objects can not move, be stopped or change the direction.

Force is a quantitative interacting parameter between two physical bodies, means an object and its environment, there are different types of forces in nature.

If an object is in its moving state then it will be either static or motion, the position of the object will only be changed if it is externally pushed or pulled.

The contact type of force are the force that occurs when we apply some effort on an object such as Spring Force, Applied Force, Air Resistance Force, Normal Force, Tension Force, Frictional Force

Non-Contact type of forces are another type of forces occur from a distance such as Electromagnetic Force, Gravitational Force, Nuclear Force
