Unlike friction, gravity is a force and acts between objects that are not touching. The correct option is d.

Gravity is the force by which an object attracts another object toward its center.

Gravity is also known as the gravitation force that acts between the two objects kept a distant apart.

Thus, option d is correct.

Answer:

c

Explanation:

When a coil of wire is stationary and there is no relative motion between the coil and a permanent magnet, there will be no induced electrical current in the coil. The correct statement in this scenario would be C. The coil and the magnet are not moving relative to each other.

Electromagnetic induction states that a change in magnetic field through a conductor (in this case, the coil of wire) will induce an electromotive force (EMF) or voltage across the ends of the conductor. This induced voltage can then drive an electric current to flow if there is a complete circuit.

When there is no electrical current flowing through a coil of wire that contains a permanent magnet, the interaction between the magnetic field of the magnet and the coil's magnetic field depends on their relative motion. In this case, if there is no movement between the coil and the magnet, the magnetic fields are not changing with respect to each other. Therefore, the absence of relative motion between the coil and the magnet is the condition in which no electrical current is induced in the coil.

Therefore, the correct statement in this scenario would be C. The coil and the magnet are not moving relative to each other.

Explanation:

:)

the characteristics of continental tropical air masses They have warm, dry air. Hence option B is correct.

Tropical Air is a Tanzanian airline operating in Zanzibar. It was the first locally owned airline in Zanzibar, starting operations in 1999 with a single aircraft. Captain Omar Haji established it. It works in Pemba, Dar es Salaam, and other areas in Tanzania. They are no longer in use.

Throughout the year, the maritime Tropical (mT) air mass is the most important moisture-bearing and rain-producing air mass. It goes poleward in the winter and is cooled by the ground surface. As a result, it is distinguished by fog or low stratus or stratocumulus clouds, rain, and limited visibility.

Meteorology (the study and forecasting of weather), climatology (the study of long-term atmospheric patterns and their impacts), and aeronomy are the three classic thematic areas of the atmospheric sciences.

Sum of Vectors

The vectors plotted in the graph are arranged using the head-to-tail method, i.e. placing the tail of the second vector at the head of the first vector. The head of the second vector indicates the sum of both vectors.

From the graph, we can see the head of the second vector lies in the point of coordinates (4,2).

This vector is represented as:

Explanation:

Answer:

See the answer below

Explanation:

1. Speed is calculated as the ratio of distance and time. Hence, Jame's speed can be calculated as:

       400/5 km/hr = 80 km/hr

The unit for the speed would be km/hr. This can also be converted to m/s:

80 km = 80,000 m

1 hr = 3,600 s

80 km/hr = 80,000/3600 m/s = 22.22 m/s

2. Since James drove 400 km in 5 hours, the distance he drove is 400 km.

3. The time it took for James to get there is 5 hours.

Answer:

2 pc

Explanation:

The parallax angle is the angle of the earth at different times in a year relative to a given closest star.

P = [tex]\frac{1}{d}[/tex]

where p is the parallax angle, d is the distance between the earth and the star

Since p = 0.5 arcsec, then;

d = [tex]\frac{1}{p}[/tex]

  = [tex]\frac{1}{0.5}[/tex]

  = 2

d = 2 pc

The star is 2 parsec away from the earth.

kinetic energy and thermal conductivity processes allow the correct answers to the questions are:

4. The answer for the total kinetic energy correct is:   D. 17761 J

5. the answer is:   C. The energy loss can increase or decrease.

4. Kinetic energy is due to the motion of bodies and is given by the relation  

           K = ½ m v²

Wher k is de kinetic energy, m the mass and v speed.

Let's look for the kinetic energy of the bullet

           K₂ = ½ 18 23²

           K₂ = 4761 J

They indicate the kinetic energy of the cannon is K = 72000 J, they ask the energy at total kinetic energy is

           [tex]K_{total}[/tex] = K + K₂

           K_{total} = 72000 + 4761

           K_{total} = 76761 J

When checking the answer, the correct one is

              D. 76761 J

5. In modern houses and systems, insulation is created to maintain heat and reduce losses

            P =[tex]\frac{A \Delta T}{R}[/tex]  

Where P is the heat flux, A the insulated area, ΔT the temperature difference and R the relationship between the thickness of the insulation and its thermal conductivity.

In this case they indicate that the flow increases and the isolated area increases. We have several possibilities

In this case it indicates that the two increases, therefore the heat requests can increase or decrease

The correct answer is :

  C. The energy loss can increase or decrease.

With kinetic energy and thermal conductivity processes we can find the correct answers to the questions that are:

4. The answer for the total kinetic energy correct is:   D. 17761 J

5. the answer is:   C. The energy loss can increase or decrease.

Answer:

It must travel farther than Earth does to complete one orbit around the Sun.

Explanation:

Each planet orbits around the Sun along an elliptical path. The farther away from the Sun a planet is, the larger the ellipse. The larger the ellipse, the longer the distance around it. Because the orbit of Mars is larger than the orbit of Earth, Mars must travel farther than Earth does to complete one orbit around the Sun.

Mercury travels a shorter distance than Earth does to complete one orbit around the Sun.

Based on the positions of the 8 planets from the sun, Mercury is closest to the sun. The implies that the distance of Mercury from sun is very short when compared to Earth or other planets.

The shorter the distance, the shorter time it would require to make a complete orbit around the sun.

For instance;

Thus, we can conclude that Mercury travels a shorter distance than Earth does to complete one orbit around the Sun.

1st law you would move forward if you were sitting right with a seatbelt

If you are driving forward and suddenly break due to inertia your body moves forward demonstrating newton's first law of motion. Therefore, option (A) is correct.

Newton’s 1st law of motion can be defined as the object will stay in the state of rest or uniform motion in a straight line until and unless an external force acts on it.

Once the body starts to move, it won't stop or change its speed until and unless some external force applies upon it one or more times. Newton's 1st law of motion is also known as law of inertia.

There are two conditions for Newton's first law of motion. If an object is at rest, velocity (v) and acceleration (a) are equal to zero. Therefore, the object will continue to be at rest state.

When a body is already in motion, velocity will be non-zero (v ≠ 0), while acceleration (a = 0) is equal to zero. Therefore, the body will continue to be in motion with the same speed and in the same direction.

Answer:

 P´ = 11.3 P

power increases 11.3 times

Explanation:

For this exercise let's use the equation for power transmitted on a string

        P = ½ μ w² A² v

when we bend the rope the area and density change

        A´ = 2 A

        μ'= 2m / l

        μ'= 2 μ

the speed of the rope is

        v² = T /μ

indicate that the tension in the two strands is the same

        v´² = T / μ´

        v´² = T / 2μ

        v´ = √ ½  v

we substitute in the power

        P´ = ½ μ´  w² A´² v´

        P´ =  ½  2μ   w²  4A   v/√2

         P´ = 8/√2  P

        P´ = 11.3 P

power increases 11.3 times

Explanation:

Answer:

Wy = - 268.3*cos(42) = - 199.38 [N]

Wx = 268.3*sin(42) = 179.52 [N]

Explanation:

To solve this problem we must make a free body diagram, in the attached image we can see a free body diagram.

Taking the inclined X & y axes with the same angle of 42°, we can see that the weight can be decomposed on both axes.

Since the angle is adjacent to the y-axis, we can use the cosine function

Wy = - 268.3*cos(42) = - 199.38 [N]

Wx = 268.3*sin(42) = 179.52 [N]

We have that for the Question "Calculate the centripetal force (in N) required  to maintain this orbit." it can be said that  the centripetal force (in N) required  to maintain this orbit is

F=62.5N

From the question we are told

An object of mass 10 kg is in a circular orbit of radius 10 m at a

velocity of 10 m/s.

Calculate the centripetal force (in N) required  to maintain this orbit.

Generally the equation for the Centripetal force  is mathematically given as

[tex]F=\frac{mv^2}{r}\\\\F=\frac{5*10^2}{8}[/tex]

F=62.5N
