The satellite space explorer flies 180600 miles in 21 hours. Find the rate of change.

Answers

Answer 1

The rate of change, or speed, of the satellite space explorer, is approximately 8600 miles per hour.

Given:

Distance = 180600 miles

Time = 21 hours

The rate of change represents the speed or velocity at which the satellite is traveling.

Rate of change (Speed) = Distance ÷ Time

Rate of change (Speed) = 180600 ÷ 21

Rate of change (Speed) = 8600 miles /hour

So, the rate of change, or speed, of the satellite space explorer is approximately 8600 miles per hour.

What is the speed of a wave that has a wavelength of 0.5 m and a frequency of two waves per second?

Answers

The speed of wave is 1m/sec  if the wavelength of wave is 0.5 meters and the frequency of the wave is 2Hz.

Right when a wave goes through reflection, it essentially remains in the medium and simply switches its going of development. The smooth wave has traveled twofold its distance. This reflection characteristic of waves is consistently found in sound waves.

Right when you let out an uproarious cry inside a gorge, you regularly hear the resonation of the holler. The sound waves travel through the medium; for this present circumstance, the air and skip off the ravine wall and return to the start of the sound (you). The result is that you hear the resonation of your holler.

We know that when a electromagnetic wave is travelling through speed v passing in a medium, it contains certain speed and wavelength which is given by the formula

c=ν × λ

where c is defined as the speed of light in vacuum,

ν is  defined as the frequency of the wave and

λ is defined as the  wavelength of the wave.

Now, we have frequency(ν) = 2Hz, and wavelength(λ)=0.5meters.

So, using the above formula, we get

c=0.5×2

=>c=1m-Hz

or c=1m/sec as 1Hz=1 /sec

Hence, wave speed is 1m/sec.

there are very large numbers of charged particles in most objects. why, then, don’t most objects exhibit static electric effects?

Answers

This is because the phenomenon of static electricity requires the separation of positive and negative charges. When two substances are in contact electrons are transferred from one to the other leaving one with an excess positive charge and the other with an equal negative charge.

There are equal numbers of positive and negative charges so an object is electrically neutral. Because the phenomenon of static electricity requires the separation of positive and negative charges.

in a gaseous mixture of massive molecules and light molecules with the same average ke, which have the greater speed?

Answers

The light molecules will have the greater speed, as their mass is much lower than that of the massive molecules. This means that they will have a higher kinetic energy per unit mass, which leads to a higher speed.

Comparing the Speeds of Massive and Light Molecules in a Gaseous Mixture

The speed of a molecule is determined by its kinetic energy, which is a measure of the energy of its motion. The kinetic energy of a molecule is proportional to its mass and the square of its velocity. Since the average kinetic energy (KE) of the two types of molecules in the mixture is the same, the lighter molecules will have a higher velocity than the massive molecules.

This is because they have less mass and the same amount of kinetic energy, so their velocity is higher in order to compensate for the lower mass. This means that the light molecules will have a greater speed than the massive molecules in the mixture.

during isokinetic testing at high angular velocities (>240 deg/s), what is the approximate torque capability of eccentric muscle actions as compared to concentric muscle actions?

Answers

Compared to concentric activities, eccentric muscle motions generated substantially higher torques (p<0.01).

Explain about the eccentric muscle?

When a force is supplied to a muscle that is greater than the momentary force the muscle produces, the contraction is eccentric (lengthening), which causes the muscle-tendon system to extend forcibly as it contracts.

An opposing force, such as a weight, is stronger than the force produced by the muscle during an eccentric motion, causing the muscle to extend while under tension. The majority of the isometric (same length) and isotonic (shortening) contraction investigations in exercise physiology have been centered on muscular load.

Describe the relationship between focal length and convex lens?

As the object distance gets very large, (compared to focal length) the distance of the image reaches focal length.

For example, if the object is a mile away, the image distance equals the focal length.

The focal length image distance is dependant on the convex surface of the lens and if the curvature of the lens changes, the focal length also changes.

Internal energy can be calculated by first law of thermodynamics as well as using specific heat.

From a microscopic perspective looking at a system at the atomic and molecular level, the internal energy U [J] of a system is the sum of the kinetic and potential energies of its atoms and molecules. Since the sum of kinetic and potential energies is mechanical energy, the internal energy of a system is the sum of atomic and molecular mechanical energies.

In other words, the internal energy is the total energy of the system associated with its microscopic constituents (made up of atoms and molecules) when viewed from a frame of reference that is stationary with respect to the body. Internal energy includes translational, rotational, and vibrational kinetic energies of molecules, potential energies within molecules, and potential energies between molecules.

In physics, the internal energy of a system is considered in terms of macroscopic properties that are very similar to atomic and molecular averages.

Answers

The pressure of the helium comparison is like:  in the large Helium Balloon is greater than the pressure in the small Helium Balloon

The huge helium balloon's increased pressure must result from the fact that there must be more moles of gas present. A balloon's walls are put under pressure when it is inflated because the air inside the balloon expands. The balloon's size consequently grows.

Temperature has an impact on the hot air balloon's internal pressure. The molecules move more quickly and forcefully against the interior wall of the balloon as they warm up. The force acting on a portion of the balloon is enhanced due to the gas particles' increased velocity, which results in an increase in pressure. The size of the balloon affects the air pressure inside as well. Pressure is inversely proportional to volume, V . If V were to double, P would drop to 1/2 its original value.

the boy in the image below pushes a box across the floor by exerting a force of 140. n at an angle of 35.0o below the horizontal. what is the magnitude of the vertical component of the applied force (fay) ?

Answers

The boy pushes a box across the floor by exerting a force of 140 N at an angle of 35° below the horizontal. The magnitude of vertical component of the applied force is 80.36 N.

In two dimensional system, a force can be resolved into two mutually perpendicular components whose vector sum will be equal to the applied force. The resolved components are usually taken to be parallel to x and y axes.

A single force can be broken down into two component forces at right angles to each other.

Given that, Force = 140 N

θ = 35°

The magnitude of vertical component of force is F sin θ = 140* sin 35° = 140* 0.574 = 80.36 N

how much energy is required to remove a proton from 157n ? the masses of the atoms 157n , 146c and 11h are 15.000109 u , 14.003242 u and 1.007825 u , respectively.

Answers

The energy required to remove a proton from ¹⁵N₇ is

The reaction to remove the proton is given as follows :

¹⁵N₇  ---->   ¹⁴C₆  +  H

The mass of ¹⁵N₇  = 15.000109

The mass of ¹⁴C₆ = 14.003242

The mass of H = 1.007825

The energy requires to remove a proton is given as:

E = ( 14.003242 + 1.007825 - 15.000109) u

E = 0.010958 × 9312.5 MeV

E = 10.2046375 MeV.

Therefore, energy is required to remove protons from 15N7 with masses of 15.000109 u, 14.003242 u, and 1.007825 u and 10.2046375 MeV of 15N7, 14C6 and H atoms of 10.2046375 MeV, respectively.

Since the effort to remove neutrons is greater than the effort to remove protons, the energy required to remove neutrons is greater than the energy required to remove protons. The rest mass energy of the nucleus is less than that of its constituent protons and neutrons.
