Answer:

The Moon spins in space in a movement called rotation. Oddly enough, it also takes the Moon about 27 days to spin around once (which is much slower than Earth's rotation, which only takes 24 hours). That means the Moon goes all the way around Earth in the same amount of time it takes to spin around just once!

Answer:

D) 735 J(oules)

Explanation:

Work is defined as force * distance

Force is defined as mass * acceleration

Given a mass of 15 kg and a gravitational acceleration of 9.8 m/s² since the box is being lifted up, the force being applied to the box is 15 kg * 9.8 m/s² = 147 N

Since the distance is 5 meters, the work done is 147 N * 5 m = 735 N/m = 735 J, making D the correct answer.

Answer:

[tex]R = 1.5* 10^{-10}m[/tex]

Explanation:

Given

[tex]r = 2.5 * 10^{-11}m[/tex] -- radius of hydrogen atom

See attachment

Required

Determine the radius of magnesium atom (R)

From the attachment, the ratio of a hydrogen atom to a magnesium atom is:

[tex]Ratio = 6mm : 36mm[/tex]

Simplify

[tex]Ratio =1 : 6[/tex]

Represent the radius as ratio:

[tex]Ratio = r : R[/tex]

Substitute [tex]r = 2.5 * 10^{-11}m[/tex]

[tex]Ratio = 2.5 * 10^{-11}m : R[/tex]

Equate both ratios

[tex]2.5 * 10^{-11}m : R = 1 : 6[/tex]

Express as fraction

[tex]\frac{2.5 * 10^{-11}m}{R} = \frac{1}{6}[/tex]

Cross Multiply

[tex]R * 1 = 2.5 * 10^{-11}m * 6[/tex]

[tex]R * 1 = 2.5 * 6* 10^{-11}m[/tex]

[tex]R * 1 = 15* 10^{-11}m[/tex]

[tex]R = 15* 10^{-11}m[/tex]

[tex]R = 1.5*10* 10^{-11}m[/tex]

[tex]R = 1.5* 10^{1-11}m[/tex]

[tex]R = 1.5* 10^{-10}m[/tex]

Hence, the radius of the magnesium atom is: [tex]1.5* 10^{-10}m[/tex]

Answer:

Explanation:

Answer:

0 becouse it will still before falling

Explanation:

In addition to the resultant force acting on an object, the mass of the object should be known to find the acceleration. So, the mass is the answer.

Newton's second law of motion states that

a = F / m

Where:

a is the acceleration of the object,

The net force acting on the object is F

m is the mass of the object.

By dividing the net force (F) by the mass (m), you can determine the acceleration (a) of the object.

So, both the net force and the mass are necessary to calculate the acceleration. So, the mass is the answer.

Answer:

If the atoms get two close then the nuclii will repell each other.

Explanation:

Since electrons are negative they are attracted to the nucleus because it is positive. If two atoms get close enough together then the electrons of each atom will be attracted to both nuclii.

Explanation:

People are wild about amusement parks. Each day, we flock by the millions to the nearest park, paying a sizable hunk of money to wait in long lines for a short 60-second ride on our favorite roller coaster. The thought prompts one to consider what is it about a roller coaster ride that provides such widespread excitement among so many of us and such dreadful fear in the rest? Is our excitement about coasters due to their high speeds? Absolutely not! In fact, it would be foolish to spend so much time and money to ride a selection of roller coasters if it were for reasons of speed. It is more than likely that most of us sustain higher speeds on our ride along the interstate highway on the way to the amusement park than we do once we enter the park. The thrill of roller coasters is not due to their speed, but rather due to their accelerations and to the feelings of weightlessness and weightiness that they produce. Roller coasters thrill us because of their ability to accelerate us downward one moment and upwards the next; leftwards one moment and rightwards the next. Roller coasters are about acceleration; that's what makes them thrilling. And in this part of Lesson 2, we will focus on the centripetal acceleration experienced by riders within the circular-shaped sections of a roller coaster track. These sections include the clothoid loops (that we will approximate as a circle), the sharp 180-degree banked turns, and the small dips and hills found along otherwise straight sections of the track.

Answer:

The braking distance of the car is 40 m

Explanation:

The two steps are;

1) Calculation (finding) of the initial kinetic energy , K.E., of the car

2) Calculation (finding) of the braking distance from the calculated K.E., of the car

The initial Kinetic energy of the car, K.E. = 1/2×m×v²

Where;

m = The mass of the car = 1,600 kg

v = The velocity of the car = 20 m/s

∴ K.E. = 1/2 × 1,600 kg × (20 m/s)² = 320,000 joules

2) The work done in stopping the car, W = The braking force, 'F' × The braking distance, 'd'

∴ W = F × d

Where;

F = The braking force = 8,000 N

d = The braking distance of the car

By energy conservation principle, the work, 'W', that is required to stop the car = The initial kinetic energy of the car, K.E.

∴ W = K.E. = 320,000 joules

Therefore, by substituting the known values for the variables, we have;

320,000 J = 8,000 N × d

∴ d = 320,000 J/(8,000 N) = 40 m

The braking distance of the car, 'd' = 40 m.

Answer: The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

Answer:

It provides shape and support for the body

Explanation:

Providing shape and support for the body is one of the many functions of the skeletal system, which is directly helpful to the circulatory system. Thus, the correct option is D.

The skeletal system is the body's central framework. This system consists of bones and connective tissue, including the cartilage, tendons, and ligaments. The system is also called the musculoskeletal system. It is made up of 206 bones.

The human skeleton serves six main functions which are providing support, movement of the body, protection, production of blood cells such as red blood cells and white blood cells, storage of ions such as calcium and phosphorus, and the endocrine regulation. Bone is a hard, dense connective tissue which is responsible for forming most of the adult skeleton, the support structure of the body of an organism.

Providing shape and support for the body is the function which is directly helpful to the circulatory system of the body.

Therefore, the correct option is D.

.c ...energy

Explanation:

Amplitude does not affect wavelength. It also does not affect wave speed. Amplitude is the energy of the wave measured from the rest position to the top of the crest. A wave with more energy has a higher up crest/ higher amplitude.

As the amplitude of a mechanical wave increases, the quantity which increases is: C. energy.

A mechanical wave can be defined as a type of wave that requires a medium for its propagation and it creates a disturbance in the medium. Thus, a good example of mechanical wave is sound wave, which is typically transported in a perpendicular direction.

Amplitude refers to the maximum displacement of a wave when measured from its equilibrium position. Also, the amplitude of a mechanical wave has no effect on the following:

Answer:

 θ = 64.5º

Explanation:

To find the angles of a vector with respect to some axis of a coordinate system, the tangent function is used.

           tan θ = [tex]\frac{y}{x}[/tex]

where y is the opposite leg and x is the adjacent leg

in this case the angle is

        θ = tan⁻¹   [tex]\frac{A_y}{A_x}[/tex]

let's calculate

        θ = tan⁻¹ [tex]\frac{15.9}{ 7.6}[/tex]

        θ = tan⁻¹ 2.09

        θ = 64.5º

this angle is with respect to the positive pâté of the x axis
