The average velocity of the car in m/s for the first leg is 36.2 m/s and the average velocity (in m/s) for the total trip is 7 m/s

Speed is the distance travelled per time taken. The S.I unit is m/s. The average speed is the ratio of the total distance travelled to the to time taken. While velocity is the distance travelled in a specific direction per time taken

Given that a race car traveling northward on a straight, level track at a constant speed travels 0.760 km in 21.0 s. The return trip over the same track is made in 26.0 s.

(a) The average velocity of the car in m/s for the first leg of the run will be

Velocity = (0.760 x 1000)/ 21

Velocity = 760 / 21

Velocity = 36.2 m/s

(b) The average velocity (in m/s) for the total trip will be

36.2 - (0.760 x 1000)/ 26

36.2 - (760) / 26

36.2 - 29.2

Answer: more light passes through

Explanation:

Answer:

1. A proton's magnetic moment arises from a fundamental quantum property called spin, which causes the proton to behave as a tiny bar magnet with a north and a south pole. When placed in an external magnetic field, the proton's spin can either align with the field or flip to orient itself against the field

2. The force can change the direction (velocity) of the proton but not its speed (magnitude).

The correct options are:

D

"Radio waves have a lower frequency, which makes them safer for humans."

B

"Radio waves take less energy to produce."

Radio waves are electromagnetic waves with frequencies on the range from 10 KHz to 10 THz.

Now, remember that all electromagnetic waves have the same speed, which is the speed of light, and the energy of a wave is proportional to its frequency.

Particularly, we can see that radio waves have small frequencies (smaller than infrared light) so these waves carry very little energy.

With that in mind, the correct options are.

D

"Radio waves have a lower frequency, which makes them safer for humans."

B

"Radio waves take less energy to produce."

These are the two main reasons of why we use radio waves.

A Capacitor is a device consisting of two conductors that can be charged with equal and opposite charges, separated by a thin insulator.

According to principle of a capacitor, capacitor is a system of conductors or dielectric.

If there is a single conductor, it cannot holds very much current then its potential reaches to its maximum values and it cannot hold more charge.

If we place another conductor near it, its potential becomes low and it is able to store more charge.

We know from the definition of the capacitor, A capacitor is a two-terminal electrical device that possesses the ability to store energy in the form of an electric charge. It consists of two electrical conductors that are separated by a distance.  

Capacitors store energy by holding apart pairs of opposite charges. The simplest design for a capacitor is a parallel plate capacitor.

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration. According to Newton's Second Law, an object's acceleration is the result of two factors working together: the object's mass, which varies depending on the materials it is made of, and the net balance of all external forces acting on it.

The magnitude of the magnetic field at the point at the center of a long, straight solenoid if the solenoid carries a current of 0.300 A and has 4.00 ×10³ windings per meter would be 1.512 ×10⁻³ N/Amps m

A magnetic field could be understood as an area around a magnet, magnetic material, or an electric charge in which magnetic force is exerted. The SI unit of the magnetic field is tesla.

The magnetic field at the point at the center of a long, straight solenoid can be calculated by using the formula

B = μnI

where B is the magnetic field

μ is the Permeability constant having a value of 1.26 × 10⁻⁶ T/m

n is the number of winding per meter

I represent the current

By substituting the respective value in the formula

B=( 1.26 × 10⁻⁶ )×  (4.00 ×10³)×0.300

B =1.512 ×10⁻³ N/Amps m

Thus, the magnitude of the magnetic field at the point at the center of a long, straight solenoid would be 1.512 ×10⁻³ N/Amps m.

The answer is time period of spring mass system does not depend on its amplitude.

The period does not depend on the Amplitude. The greater the amplitude, the more the distance to be covered, but it will do so more quickly. The period won't change since the effects of distance and speed cancel each other out. As the amplitude rises, the mass moves farther with each cycle. Therefore, increasing the amplitude has no overall impact on the oscillation's period.

A kind of energy called sound is created when objects vibrate. For it to spread, a medium is needed. As a result, sound cannot travel through a vacuum because there is nothing for the sound waves to travel through. The object's back and forth movement creates the sound. Sound vibration is the name for this. Additionally called oscillatory motion. Oscillation describes the regular rhythmic back-and-forth movement.

The time required to complete a task is referred to as a period. An occurrence is referred to as periodic if it happens frequently. The period is the length of time it takes for a periodic event to repeat itself. The particle's time period is determined by how long it takes it to complete one vibration cycle.

A sound wave's amplitude measures the height of the wave. When a sound is made, the maximum displacement of the medium's vibrating particles from their mean position determines the amplitude of the sound wave. It is the separation between the wave's crest or trough and its mean location.

weight of bricks = 3500 kg

length of bricks = 1.8 m

To Find:

The average useful power output of robot is

The time taken by robot to lift bricks is

Solution: Useful power output means the electric or mechanical energy made available for use, exclusive of any such energy used in the power production process.

P = W/t

P = 5.5/12*3600

P = 0.0001 W

So, average useful power output of robot is 0.0001 W

t = W/P

W = mgh So t = mgh/P
