Answer:

B. An attractive force between two objects due to their mass

Explanation:

Answer:

B

Explanation:

Gravity is a force that pulls 2 objects towards each other and varies depending on mass. The earth for example is large enough to have a gravitational force that keeps us down. The sun has a gravitational force that keeps the Earth in orbit.

Answer:

a. The component of the net force which make up the apparent weight are added to each other at the bottom and subtracted (the centripetal force from the weight) at the top)

b. Apparent weight at the top is approximately 519.06 N

Apparent weight at the bottom is approximately 558.94 N

Explanation:

a. The apparent weight at the top is different from the apparent weight at the bottom of a moving Ferris wheel because of the opposite direction in which the centripetal force acts at the top and the bottom, which are upwards and downwards respectively, while the weight acts downwards constantly

b. The given parameters are

The radius of the Ferris wheel, r = 7.2 m

The period for one complete revolution, t = 28 seconds

The angle covered in one revolution, θ = 2·π radian

The mass of the person riding on the Ferris wheel, the passenger  = 55 kg

Therefore, we have;

The angular speed, ω = Δθ/Δt = 2·π/(28)

From which we have;

Centripetal force, [tex]F_c[/tex] = m × ω² × r

Substituting the known values, we have [tex]F_c[/tex] = 55 kg × (2·π/(28 s))² × 7.2 m ≈ 19.94 N

The centripetal force, [tex]F_c[/tex] = 19.94 N always acting outward from the center

Weight = Mass × Acceleration due to gravity

The weight of the passenger = 55 kg × 9.8 m/s² = 539 N

The weight of the passenger = 539 N always acting downwards

At the top of the Ferris wheel the the centripetal force is acting upwards and the weight is acting downwards

Therefore;

The net force, which is the apparent weight of the passenger at the top [tex]F_{NET_{Top}}[/tex] = 539 N - 19.94 N ≈ 519.06 N

Apparent weight at the top ≈ 519.06 N

At the bottom of the Ferris wheel the weight is acting downwards and the centripetal force is also acting downwards

Therefore;

The net force at the bottom, which is the apparent weight of the passenger at the bottom [tex]F_{NET_{bottom}}[/tex] = 539 N + 19.94 N ≈ 558.94 N

Apparent weight at the bottom ≈ 558.94 N.

Answer:

I think it's 1.625 m/s2

f=150N

m=.5kg

150/.5=300

Answer:

Asha traveled a distance of 50 m

The displacement is 20 m north.

Explanation:

Distance and Displacement

A moving object constantly travels for some distances at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:

dtotal=d1+d2+d3+...+dn

This sum is obtained independently of the direction the object moves.

The displacement only takes into consideration the initial and final positions of the object while moving. The displacement, unlike distance, is a vectorial magnitude and can even have magnitude zero if the object starts and ends the movement at the same point.

Asha walks 15 m west, 20 m north, and 15 m east. The total distance is

dt=15 m + 20 m + 15 m = 50 m

Asha traveled a distance of 50 m

Note the final position is 20 m above the initial position since she goes 15 m west and 15 m east. Thus the displacement is 20 m north.

Answer:

i think its B.NOT all potential energy is converted to kinetic energy

Answer:

Maybe,  B. Not all potential energy is converted to kinetic energy.

Explanation:

Even if air resistance slows down the ball, the potential energy is the same. But if air resistance is in the way, not all of the potential energy can be converted to kinetic energy. Some of the energy has to be used to push the air molecules out of the way.

Answer:

Ammeters are connected in series and voltmeters are connected in parallel in a circuit

Answer:

The earth rotates west to east

Explanation:

Considering that the sun doesn't really move and the earth is rotating around the sun, and it is moving from east to west with us (the earth) facing it in which means the earth rotates around the sun west to east!

Answer: 300 J

Explanation:

Force = 150 KJ

Distance = 2.0 m

The minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically would be 2940 Joules, as the work done is the product of the force applied to the displacement of the object, therefore the correct answer is option B.

The total amount of energy transferred when a force is applied to move an object through some distance

The work done is the multiplication of applied force with displacement.

Work Done = Force × Displacement

As given in the problem we have to find out the minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically.

The minimum work done = 150 × 9.8 × 2

                                          = 2940 Joules

Thus, The minimum amount of work done by a hydraulic lift to raise a 150-kg aluminum block 2.0 meters vertically would be 2940 Joules.

Electron is very light compared to proton and neutrons.

Given that the mass of an electron is

A) equal to the mass of a proton

B) less than the mass of a neutron

C) greater than the mass of a proton

D) equal to the mass of a neutron

The correct answer is B which is less than the mass of the neurons.

Answer:

According to the Newton's law of gravitational every object in the universe attracts every other objects with a force which is called gravitational force.This gravitational force is (i) directly proportional to the product of their masses and (ii) inversely proportional to the square of the distance between their centres.

Explanation:

Newton's law of gravitational is called the universal law because it is applicable to all the bodies either terrestrial or celestial having any shape,size,mass or at any distance apart with any medium between them,at any time(past,present or future).

Answer:

B) a louder sound of the same pitch.

Explanation:

Given that the loudspeaker produces a sound wave of frequency 50hz and the amplitude of the sound wave is increased.

As loudness of the sound depends on the amplitude of the sound while pitch depends on the frequency of the sound.

On increasing the amplitude of the sound there is no effect on the frequency of the sound, so, the loudness of the sound will increase while the pitch remains unchanged.

Therefore, on increasing the amplitude of the soundwave a louder sound of the same pitch is heard.

Hence, option (B) is correct.

Answer:

I think it's 5.

Explanation:

Answer: 4 vectors

Explanation:

Answer:

Newtons.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]

Where;

F represents force measured in Newton.

m represents the mass of an object measured in kilograms.

a represents acceleration measured in meter per seconds square.

Newtons is a measurement we use to determine the amount of force used to move an object by a simple machine. It is the International System of Units (SI) used to measure force and has a symbol of N.

Basically, it was named after Sir Isaac Newton based on his fundamental works in the field of mechanics (motions).

Explanation:

Answer:

Vf = 9.46 m/s

Explanation:

In order to find the final velocity of the dog we can use third equation of motion:

2gh = Vf² - Vi²

where,

g = acceleration due to gravity = 9.8 m/s²

h = height of window = (15 ft)(1 m/3.28 ft) = 4.57 m

Vf = Final Velocity of Dog = ?

Vi = Initial Velocity of Dog = 0 m/s

Therefore,

(2)(9.8 m/s²)(4.57 m) = Vf² - (0 m/s)²

Vf = √(89.572 m²/s²)

Vf = 9.46 m/s

Answer:

c. the speed of a planet is greatest when it is closest to the Sun.

Explanation:

Johannes Kepler was an astronomer who discovered that planets had elliptical orbits in the early 1600s (between 1609 and 1619).

The three (3) laws published by Kepler include;

I. The first law of planetary motion by Kepler states that, all the planets move in elliptical orbits around the Sun at a focus.

II. According to Kepler's second law of planetary motion, the speed of a planet is greatest when it is closest to the Sun.

Thus, the nearer (closer) a planet is to the Sun, the stronger would be the gravitational pull of the sun on the planet and consequently, the faster is the speed of the planet in terms motion.

III. The square of any planetary body's orbital period (P) is directly proportional to the cube of its orbit's semi-major axis.

Answer:

A planet moves faster when it is closer to the Sun.

Explanation:

Kepler law!
