Answer:

Due to waves.

Explanation:

The can merely moves up and down because the movement of the waves that propagate away from the disturbance caused by the boat. The Can has low density due to low mass and high volume which allow the can to float on the surface of water after prevent it from the drowning. The wave moves the can up and down but prevent it from going deep inside the water so we can say that the can moves due to movement of waves in water.

Answer : At half distance between the center of the Magnetic field the magnetic pole the effect of the magnetic field generated will be half as strong

Explanation:

Magnetic force  ∝  1 / d^2

This simply means increase in the squared distance of an object leads to the decrease in the effect of the magnetic field generated by a current carrying wire.  

Hence ;  

At half distance between the center of the Magnetic field the magnetic pole, the effect of the magnetic field generated will be half as strong

Half the distance from a current-carrying wire to the body required to stand, in order for the magnetic field generated by the wire to be half as strong.

The magnetic field is the field in the space and around the magnet in which the magnetic field can be fill.

The value of magnetic field is reduced from a wire, with the distance of the wire.

The magnetic field is inversely proportional to the square of the distance of the current-carrying wire.

Hence, half the distance from a current-carrying wire to the body required to stand, in order for the magnetic field generated by the wire to be half as strong.

Answer:

Solar nebula.

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Basically, the planets are divided into two (2) main categories and these includes;

1. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.

2. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

These outer planets are made mostly of gases (hydrogen and helium) causing them to be less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.

Some examples of the planet found in the solar system are Mars, Venus, Earth, Mercury, Neptune, Jupiter, Saturn, Uranus, Pluto, etc.

Scientists have been able to understand and discover that, gravity pulled materials (low-density cloud of interstellar gas and dust known as a nebula) together forming the planetary bodies in our solar system.

A dark nebula can be defined as an interstellar cloud that is so dense as a result of high concentration of gas and dust and as such it obscures the visible wavelengths of light from stars behind it, thus appearing completely opaque (dark patch) in front of a bright emission nebula or in regions having plenty stars.

The characteristics of a nebulae are;

I. It contain hydrogen.

II. Clouds of gas and dust

III. It is needed to create a star.

The capacitance of the given capacitor is approximately 1.4805 × [tex]10^{(-10)[/tex]F.

The capacitance (C) of a capacitor is determined by the formula:

C = (ε₀ ×A) / d

Where:

C is the capacitance

ε₀ is the permittivity of free space (ε₀ ≈ 8.85 × [tex]10^{(-12)[/tex] F/m)

A is the area of the plates

d is the distance between the plates

Given:

Area of the plates (A) = 5.25 × [tex]10^{(-5)[/tex]m²

Distance between the plates (d) = 3.14 × [tex]10^{(-6)[/tex] m

Using the given values, we can calculate the capacitance:

C = (ε₀ ×A) / d

C = (8.85 × [tex]10^{(-12)[/tex] F/m) × (5.25 × [tex]10^{(-5)[/tex] m²) / (3.14 × [tex]10^{(-6)[/tex]m)

Simplifying the expression:

C = (8.85 × 5.25 × [tex]10^{(-12 - 5)[/tex]) / (3.14 × [tex]10^{(-6)[/tex])

C = (46.4625 × [tex]10^{(-17)[/tex]) / (3.14 × [tex]10^{(-6)[/tex])

C = 14.805 × [tex]10^{(-17 - (-6)}[/tex])

C = 14.805 × [tex]10^{(-11)[/tex]

Using scientific notation,  capacitance as:

C = 1.4805 × [tex]10^{(-10)[/tex] F

Therefore, the capacitance of the given capacitor is approximately 1.4805 × [tex]10^{(-10)[/tex] F.

Answer:

emf = - 0.622 V

Explanation:

The electromotive force is given by Faraday's law

         emf = [tex]- \frac{d \phi }{dt}[/tex]

         Ф = B. A

bold indicates vectors

        Ф = B A cos θ

in this case it is indicated that the magnetic field is constant and the angle between the magnetic field and the normal to the area is parallel, so the cos 0 = 1

we substitute

           emf = [tex]- B \ \frac{dA}{dt}[/tex]

the area of ​​the circle is

          A = pi r²

         [tex]\frac{dA}{dt} = \pi 2r \ \frac{dr}{dt}[/tex]

       emf = B 2π r [tex]\frac{dr}{dt}[/tex]

speed is defined

       v = [tex]\frac{dr}{dt}[/tex]

we substitute

        emf = - 2π B r v

let's calculate

        emf = - 2π  0.5  1.65  π0.12

Answer:

1) The car is slowing down

2) A = 40N forward & B = 25N up

Explanation:

Whenever you're dealing with forces on moving objects, it is important to look at each of the numbers and the directions they're going in.

With the racecar, we see it has four forces on it, 2,000 N up and down, 8,000 back, and 6,000 N forward. Now, each of these forces are going in their respective directions, but they are most in comparison with the force going in the opposite direction (vertical axis, horizontal axis). The two 2,000 N forces will cancel each other out since there is an equal force in both directions, causing a net force of 0 N on the vertical axis. This is because the car is most likely moving on a flat surface. As for the horizontal axis, we simply subtract 6,000 & 8,000 to get a net force of -2,000 N in the backwards direction, telling us that the car is slowing down.

As for the boxes, we see the same vertical and horizontal axes, but separated to each box. Box A has a net force of 40 N in the forward direction and Box B has a net force of 25 N in the upward direction.

Explanation:

3.75 N

Explanation:

F = k(q)(q)/r^2 = 5 N

F' = k(q)(3q)/(2r)^2

= k×3(q)(q)/4r^2

= (3/4)[k(q)(q)/r^2]

= (3/4)F

= (3/4)(5 N)

= 3.75 N

The new electric force is 3.75 N.

The force on the charges by Coulomb's law is given by;

F = kq1q2/r^2

where q1=q2

F = kq1^2/r^2

Where F = 5N

If one of the charges triples;

q2 = 3q1

distance doubles = r = 2r

F' = 3kq1^2/4r^2

So;

F' = 3/4 F

F' = 3/4 × 5 = 3.75 N

The new electric force is 3.75 N.

Calculations involving forces

The resultant force is the single force that has the same effect as two or more forces acting together.

Two forces in the same direction

Two forces that act in the same direction produce a resultant force that is larger than either individual force.

You can easily calculate the resultant force of two forces that act in a straight line in the same direction by adding their sizes together.

Example

Two forces, 3 N and 2 N, act to the right. Calculate the resultant force.

Two arrows, one above the other, both pointing to the right, one labelled 2 N and one labelled 3 N. Then an equals sign and then another arrow to the right labelled 5 N.

Two forces acting in the same direction

Resultant force F = 3 N + 2 N = 5 N to the right.

The resultant force is 5 N to the right.

Two forces in opposite directions

Two forces that act in opposite directions produce a resultant force that is smaller than either individual force.

To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force.

The direction of the resultant force is in the same direction as the larger force.

Example

A force of 5 N acts to the right, and a force of 3 N act to the left.

Calculate the resultant force.

Two arrows, one above the other, one pointing to the left, labelled 2 N, the other pointing to the right labelled 3 N. Then an equals sign, with an arrow to the right labelled 1 N.

Two forces acting in opposite directions

Resultant force F

Resultant force F = 5 N - 3 N = 2 N to the right.

The resultant force is 2 N to the right.

Answer:

Explanation:

The oly way we can figure this out is if the boy is pulling the sled at a constant velocity. If not, we need a value for acceleration, and you don't have that here. If the boy is pulling the sled at a constant velocity, then the value for acceleration is 0, making this a really simple problem. I'm going with that, since there is no way to answer you otherwise. If velocity is not constant, please either repost the question or put it in the notes section under the question as it stands. If acceleration is 0, then

F - f = ma becomes

F - f = m(0) which is

F - f = 0 and

F = f which says that the applied force is the same as the frictional force. We need then to find the frictional force, which has an equation of

f = μ[tex]F_n[/tex] where normal force is the same as the weight of the 2 girls. We will find that, then:

Each girl's mass is different so the normal force/weight equation is

w = (30.0)(9.8) + (40.0)(9.8) to get

w = 290 + 390 and

w = 680. Plug that into the frictional force equation:

f = (.120)(680) so

f = 82N

Explanation:

Newton's first law of motion states that every object will continue in a state of rest or uniform motion in a straight line unless a resultant force acts on it

balanced force means resultant force is 0N

this means that the speed will not change as it uniform and the direction will not change because it will continue at the same speed in a statight line and direction

Answer:

When Copernicus first systematically created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model because the Catholic Church, which was the power at the time, stated it was false, and anybody who believed Copernicus and spread the "myth" were excommunicated or even executed. This was because a sun centered universe would mean that everything the Catholic Church had been teaching about how the Earth was the center of the universe would be false. If people believed it, the church would no longer be seen as the infallible authority, so they needed to stop it from spreading.
