TRUE OR FALSE to establish vehicle balance, improve visibility, and vehicle control, a driver should lean on the console and sit as low as possible in the seat.

Answer:

  96 m

Explanation:

The average velocity over those 4 seconds is the velocity after 2 seconds:

  30 m/s -(2 s)(3.0 m/s^2) = 24 m/s

The displacement is the product of this average velocity and the duration of the acceleration:

  d = (24 m/s)(4 s) = 96 m

The boat covered 96 m while being accelerated.

Explanation:

The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.

A runner taking part in a 400-m dash must run around the end of a track that has a circular arc with a radius of curvature of 38 m. if he completes the 400 m dash in 47.6 s and runs at a constant speed throughout the race as he runs the curved part of the track, the centripetal acceleration of the runner in the 400-m dash is 32.24 m/s².

In order to calculate the centripetal acceleration of the runner in a 400-m dash, we must first consider the circular arc with a radius of curvature of 38 m. The speed of the runner throughout the race must also remain constant. As the runner completes the 400-m dash in 47.6 s, we can then calculate the centripetal acceleration as he runs the curved part of the track.

The centripetal acceleration (ac) is equal to the square of the speed of the runner (v) divided by the radius of curvature of the track (r). Therefore, the centripetal acceleration can be calculated using the equation ac = v²/r.

Given that the speed of the runner is constant throughout the race, we can calculate the centripetal acceleration as follows: ac = (400 m/47.6 s)²/38 m = 32.24 m/s².

Therefore, the centripetal acceleration of the runner in the 400-m dash is 32.24 m/s² as he runs the curved part of the track.

The speed of the volleyball will be 3.6 m/s if  0.27-kg volleyball has a kinetic energy of 1. 8 J

A scalar concept known as speed describes the pace at which an object moves, regardless of the direction in which it moves. It is the amount of distance covered in a given amount of time, and is typically expressed in metres per second, kilometers per hour, or miles per hour. By dividing the distance travelled by the time needed to cover that distance, speed may be computed.

We can use the formula for kinetic energy to solve this problem:

Kinetic energy = 1/2 × mass × velocity²

where kinetic energy is given as 1.8 J, mass is given as 0.27 kg, and we need to find the velocity.

Rearranging the formula, we get:

velocity = √(2 ×kinetic energy / mass)

Plugging in the given values, we get:

velocity = √(2×1.8 J / 0.27 kg) = √(12.96) = 3.6 m/s

Therefore, the speed of the volleyball is 3.6 m/s.

The mutual inductance between the coils is 6.25μH. the coefficient of coupling between the coils is approximately 0.447.

The mutual inductance between the coils can be determined using the formula:M = (Δφ_Y) / (N_X * ΔI_X)
Where M represents the mutual inductance, Δφ_Y is the change in flux in coil Y, N_X is the number of turns in coil X, and ΔI_X is the change in current in coil X.
Plugging in the values given, we have: M = (5mWb) / (200 * 4A)

M = 5mWb / 800A

M = 6.25μH. Therefore, the mutual inductance between the coils is 6.25μH.

(b) The coefficient of coupling (k) can be calculated using the formula:

k = M / √(L_X * L_Y)

Where k represents the coefficient of coupling, M is the mutual inductance, L_X is the self-inductance of coil X, and L_Y is the self-inductance of coil Y.
Substituting the given values: k = (6.25μH) / √((80mH) * (60mH))

k = 6.25μH / √(4.8mH^2)

k ≈ 0.447. Therefore, the coefficient of coupling between the coils is approximately 0.447.

It would take approximately 2.4688 × 10^17 seconds or 7.82 million years for gas to travel from the core of the galaxy to the end of the jet, assuming a constant speed of 5000 km/s.

To calculate the time it would take for gas to travel from the core of the galaxy to the end of the jet, we need to use the formula: time = distance / speed.

Given that the jet in NGC 5128 is traveling at 5000 km/s and is 40 kpc (kiloparsecs) long, we first need to convert the distance from kpc to km. 1 kpc = 3.086 × 10^16 meters, which means 1 kpc = 3.086 × 10^19 km.

Therefore, the length of the jet in kilometers is 40 x 3.086 × 10^19 km = 1.2344 × 10^21 km.

Now we can calculate the time it would take for gas to travel from the core of the galaxy to the end of the jet as follows:

time = distance / speed
time = 1.2344 × 10^21 km / 5000 km/s
time = 2.4688 × 10^17 seconds

So, it would take approximately 2.4688 × 10^17 seconds or 7.82 million years for gas to travel from the core of the galaxy to the end of the jet, assuming a constant speed of 5000 km/s.

Rusty Schweickart said that astronauts on the international space station (ISS) orbit the Earth every 90 minutes.

Finding the conditions that led to Earth's formation around other stars could mean that habitable planets could be forming elsewhere in the universe.

How far do we have to rewind the clock to the beginning of our solar system? About 4.6 billion years.

Our Earth started out as a ball of dust and gas.

The same process that started our solar system formation is happening 7,000 light-years away in the Orion Nebula.

To compress the gas and dust into dense stars and planets, takes a supremely powerful event, supernova explosion is needed.

Super-heated plasma blasts into space at millions of miles per hour following a supernova.

A host of different factors have to line up to get a planet just like the Earth. What 3 things does Professor Krauss say you have to have? The right size, the right distance from the sun, and the right kind of atmosphere.

Gravity is a powerful force. But specks of dust are far too small to pull on each other to form planets.

Launching a half ton canister at over 100 miles an hour gives the dust particles just enough gravity.

The Germans think that the force that binds the dust particles together is electrostatic force.

Turning dust balls into rocks takes a whole new process. A cosmic ray collision.

Eventually the planetesimals (baby planets) get to the size of asteroids, kilometers across.

Baby Earth is now the size of a few city blocks. Big enough for a new force to take charge. That force is gravity.

So this formation process which was taking a long time to get to size where gravity kicks in, suddenly gets kicked into overdrive and the protoplanet grows very rapidly.

The attraction or repulsion between charged particles is called the electric Coulomb force.

Coulomb force, also called electrostatic force or Coulomb interaction, is the ability of a particle or object to attract or repel other particles or objects with an electrical charge. It is also the basis of a law known as Coulomb's inverse square law, or simply Coulomb's law, which measures the force acting between two stationary charged particles.

This rule has been known for a long time, but the French physicist Charles-Augustin de Coulomb did not publish it until 1785, and it bears his name.

Because it allowed the amount of charge to be discussed in a meaningful way, Coulomb's law was crucial to the development of the theory of electromagnetism, and perhaps even its starting point.

To find the number of revolutions the tire makes during this motion, we need to calculate the distance traveled by the tire and divide it by the diameter of the tire.

First, we need to find the distance traveled. This can be calculated using the formula:

distance = (initial velocity + final velocity)/2 * time = (0 + 21.4 m/s)/2 * 5.1s = 110.7m

Next, we need to convert the diameter of the tire from cm to m.

diameter = 38.2 cm / 100 cm/m = 0.382 m

Now we can calculate the number of revolutions by dividing the distance traveled by the diameter of the tire:

revolutions = distance / diameter = 110.7m / 0.382 m = 290.64

Therefore, the tire makes 290.64 revolutions during this motion

Note that it is assuming that the tire is not slipping. When the tire is slipping, this result can be different.
