Answer:

Rocks and pebbles that hit Earth's atmosphere and burn up are ______. ... an object in motion stays in motion unless acted upon by another force ... Kepler's Laws of Motion explain why ______. ... planets closer to the sun travel faster in their orbits than planets that are far away ... comets have long tails ... objects can move.

Explanation:

Kepler's Laws of Motion  explain why planets closer to the sun travel faster in their orbits than planets that are far away from the sun.

According to Kepler's first law the sun is at one of the foci of the planets' elliptical orbits around the sun, . Perihelion, the name for the point at which a planet is closest to the sun, and aphelion, the name for the point at which a planet is farthest from the sun.

According to Kepler's third law, the squares of the revolutionary periods  of the planets is directly proportional to the cubes of their mean distances from the sun.  

Therefore, planets closer to the sun travel faster in their orbits than planets that are far away from the sun. Thus, option A is correct.

Answer:

yes

Explanation:

The teacher has traveled a distance of 1000 meters, which is equal to the distance to the school (1 km = 1000 meters), there is no more distance left to reach the school. The teacher has arrived at the school.

To calculate the distance traveled by the teacher in 10 seconds, we can use the equation of motion:

s = ut + 1/2at^2

where s is the distance traveled, u is the initial velocity (which is 0 since the teacher starts from rest), a is the acceleration, and t is the time.

Given:

u = 0 m/s (starting from rest)

a = 20 m/s^2 (acceleration)

t = 10 s (time)

Substituting the values into the equation:

s = (0)(10) + 1/2(20)(10)^2

s = 0 + 1/2(20)(100)

s = 0 + 1/2(2000)

s = 0 + 1000

s = 1000 meters

Therefore, the teacher would have traveled 1000 meters in 10 seconds.

To determine the remaining distance to reach the school, we subtract the distance traveled from the total distance:

Remaining distance = Total distance - Distance traveled

Remaining distance = 1000 meters - 1000 meters

Remaining distance = 0 meters

Approximately 47.37% of the soil volume is pore space, and approximately 52.63% is solid particles.

To calculate the percentage of pore space and solid particles in the soil volume, we can use the following formula:

Pore space percentage = ((Particle density - Bulk density) / Particle density) x 100

Solid particles percentage = 100 - Pore space percentage

Given:

Bulk density = 1.4 Mg/m³

Particle density = 2.66 Mg/m³

Substituting the values into the formulas:

Pore space percentage = ((2.66 - 1.4) / 2.66) x 100

Solid particles percentage = 100 - Pore space percentage

Calculating the values:

Pore space percentage ≈ 47.37%

Solid particles percentage ≈ 52.63%

Therefore, approximately 47.37% of the soil volume is pore space, and approximately 52.63% is solid particles.

Answer:

The power required to move the box 8.0 meters in 3 seconds is approximately 53.33 watts.

To determine the power required to move the box, we need to calculate the work done first. The work done is given by the equation:

Work = Force × Distance × Cos(θ)

Where:

Force is the magnitude of the force applied (20 N in this case)

Distance is the distance moved (8.0 m in this case)

θ is the angle between the force and the direction of motion (we assume it to be 0° since the box is moved at a constant speed)

Since the force and distance are given, we can calculate the work done:

Work = 20 N × 8.0 m × Cos(0°)

= 20 N × 8.0 m × 1

= 160 J

The power required to do this work is given by the equation:

Power = Work / Time

Where:

Work is the work done (160 J in this case)

Time is the time taken to do the work (3 s in this case)

Let's calculate the power:

Power = 160 J / 3 s

= 53.33 W

Therefore, the power required to move the box 8.0 meters in 3 seconds is approximately 53.33 watts.

The most likely causes of electrons being emitted in the photoelectric effect is an increase in the intensity of the light, a decrease in the threshold energy of the photons, or a change  in the material of the emitter to one with a higher work function.

The photoelectric effect is a phenomenon in which electrons are emitted from a material when it is exposed to light. This is a result of the absorption of energy from photons, the particles that make up light. The photoelectric effect was first discovered in 1887 by Heinrich Hertz and was later explained by Albert Einstein in 1905. The effect has since been used in a variety of devices, such as photomultipliers and photodiodes, which are widely used in scientific experiments and everyday applications.

Intensity is a measure of the amount of energy present in the light, and increasing the intensity can result in a higher number of photons with enough energy to be emitted from the emitter. Decreasing the threshold energy of the photons means that photons with less energy can be emitted, which would result in electrons being emitted. Changing the material of the emitter to one with a higher work function means that photons with lower energy can be emitted, again resulting in electrons being emitted.

Overall, the changes that would cause electrons to be emitted in the photoelectric effect are increasing the intensity of the light, decreasing the threshold energy of the photons, or changing the material of the emitter to one with a higher work function.

88.5 m is the length of the pendulum. This an be solved using the concept of oscillation.

The process of any amount or measure repeatedly varying about its equilibrium position in time is referred to as oscillation. Another way to describe oscillation is as a periodic change in a substance's value between two values or around its midpoint.

Because oscillations are defined as a specific amount of movement of a solid body correlated to the distance travelled or the time required for it, oscillations and vibrations are not the same thing. The difference between the two is that vibration is the motion or change that oscillations induce in the body.

When small angles oscillate under the assumption that the supplied pendulum is oscillating, the oscillation time formula for a mathematical pendulum is:

T=2π × √(L/g)

or, L = (T/π)² × g

or, L = (290/π)² × 9.8

or, L = 88.5 meters

Answer:

(3rd Question about the Black Widow Pulsar)

J1311 is a fast spinning neutron star, which means it emits strong beams of radiation from it's poles.

As the beam of the pulsar sweeps across the surface of the companion star, it heats it up and blows its material outward into space, thus decreasing its mass.

Due to the fixed ends, a wave that is propagating up the string in one direction will reflect at the end and return inverted. The standing wave on the string is created by these two similar waves moving in the opposite direction.

When two waves with the same frequency and amplitude move in opposition to one another and interfere with one another, a standing wave result.

The string's basic frequency is the lowest resonance frequency (n=1). As integer multiples of the fundamental frequency, all higher frequencies are referred to as harmonics. The strings on all stringed musical instruments are fastened at both ends.

The n frequency is related to the fundamental frequency by the eq.

\(f_{n}=nf_{1}\)

or

\(f_{1}=\frac{f_{n}}{n} \: \: \: \: \: \:\: \: \: \: \: \: \: \: (1)\)

besides, we know that,

\(f_{n+1}=(n+1)f_{1}\)

or

\(f_{1}=\frac{f_{n+1}}{n+1} \: \: \: \: \:\: \: \: \: \: \: (2)\)

matching eq. (1) to (2),

\(\frac{f_{n}}{n}=\frac{f_{n+1}}{n+1}\)

\(f_{n}(n+1)=f_{n+1}n\)

isolating n from this eq.,

\(n = \frac{f_n}{f_n+1- f_n} = \frac{15}{20- 15}\)

Once got the n value, just insert in eq. (1) so you can know the fundamental frequency,

\(f_1= \frac{f_n}{n} = \frac{15Hz}{3} = 5Hz\)

Therefore, 5Hz is the fundamental frequency.
