When a ball rolls along the carpet, it slows down faster than when it is rolled on the floor. What transfer of energy explains this observation?

Answer:

Insulators such as glass, mica, rubber or plastic used to coat metals and other conductors help stop or reduce the flow of electrical current. This helps prevent shock, fires, and short circuits.

Explanation:

Answer:

At the critical angle the angle of refraction (outside the medium) is 90°

Ni sin θ = Na sin 90° = 1    assuming outside medium is air

sin θ = 1 / Ni            where Ni is the refractive of the medium involved

The force can be defined as rate of change in momentum because consists of the action of rotating or twisting a body around its axis of rotation (pole) through the application of a force.

The magnitude of the moment (M) is defined as the product of the magnitude of the force (F) and the distance (d) between the line of action of the force and the axis. The unit of moment of a force in the international system of units is N.m.

Torque, or moment of a force, is the tendency of a force to rotate a body on which it is applied. Torque is a vector perpendicular to the plane formed by the force and radius of rotation vectors.

Make-up of Hydrogen

Hydrogen atoms are extremely simple. They are the first atom on the periodic table, this means that they only have 1 proton. The majority of hydrogen atoms don't even have a neutron. As for electrons, hydrogen atoms with no charge have 1 electron. All of this means that for almost all hydrogen atoms the nucleus is made of one singular proton.

Diagram

The diagram shows a hydrogen atom. It looks like one circle because it is just showing the singular proton found in the nucleus. Electrons are extremely small compared to protons, so the electron is not shown in the picture. It is very hard to accurately depict electrons on diagrams like this because of their size and the fact that we can never know where they are. So, the diagram may look too simple but it just depicts how most hydrogen nuclei look.

Answer: It only has 1 proton.

Answer: work is the pressure acting through the change in volume

Explanation:

In the same way that work is defined as force operating over a distance,  work is the pressure acting through the change in volume.   Pressure is comparable to force in pressure–volume work, while volume is analogous to distance in the classic definition of work.

Just as we say that work force acting over a distance,for fluids,we can say that work is the pressure acting through the change in volume. for pressure- volume work, pressure is analogous to force, and the traditional defination of work.

Answer:

0.6

Explanation:

the original wire is three times the length there fore the longer the wire the more resistance

therefore the resistance of the original wire is 3 times greater making it 0.6

Let's find the relationship

The current flowing in the 4 ohms resistor connected in series with 5-ohm resistor is determined as 1.0 A.

The equivalent resistance of the circuit is determine as follows;

Rt = R1 + R2

Rt = 4 ohms + 5 ohms = 9 ohms

The current flowing in the 4 ohms resistor is determined from Ohms law as shown below;

V = IR

I = V/R

I = 9/9

I = 1.0 A

Since the circuit is in series arrangement, same current will flow in 5 ohm and 4 -ohm.

Medium and heavy duty vehicles require a better braking option hence they ought to have an exhaust brake.

A brake is used to slow down or stop an automobile. When the brake is applied, the speed of the automobile continues to decrease until it comes to a complete halt.

Friction brakes are apt for light vehicles that may not have the tendency to overheat. However, heavy duty vehicles may overheat often and do require an exhaust brake.The exhaust brake is most fitted for heavy duty vehicles and diesel engines.

Answer:

As we know by Newton's III law that if an action force is applied on an object then the reaction force of same magnitude in opposite direction will act on the other.

So here when ball is shot using launcher then the force will be same on launcher as well as ball so we can say

now since force is of same magnitude for both both then we will have

so from above we can say that both ball and launcher will have same impulse but opposite in direction.

Now since ball will have less mass so here it will have more speed while launcher is heavy in mass so its speed is slow or very small as comapre to ball.

Answer:

F

Explanation:

Answer:

f λ = c = 3.00E8      frequency * wavelength = speed of light

λ = c / f = 3.00E8 / 4.0E14 = 7.5E-7 m

Note 1 angstrom = 1.00E-10 m and 1 milli-micron = 1.00E-9 m

So the wavelength would be 7500 angstroms

The visible spectrum is 4000 A - 7000 A  or 400 - 700 milli-microns

The decay constant for radium-226 is larger than the decay constant for carbon-14 due to its obtained value.

The reduction in the number of radionuclides per unit time is the rate of decay.

The decay constant of the radium-226 is;

[tex]\lambda_1=\frac{ 16}{100}\times 266 \\\\ \lambda_1= -36.16[/tex]

The decay constant of the carbon-14 is;

[tex]\lambda_2=\frac{ -57.3}{100}\times 14 \\\\ \lambda_1= -802.2[/tex]

Hence, the decay constant for radium-226 is larger than the decay constant for carbon-14.

Answer:

  0.693/1600 > 0.693/5730

Explanation:

The decay constant is the reciprocal of the time it takes for the radioactivity to decline to about 36.8% of its original value. It is the value of k in the multiplier e^(-kt), which tells the fraction remaining after time t.

When compared to the half-life, h, the value of k is ...

  k = 0.693/h . . . . . decay constant for half-life h

Effectively, the decay constant is proportional to the inverse of the half-life. The constant of proportionality is ln(2) ≈ 0.693.

__

decay constant for radium-226:

  0.693/1600 ≈ 4.33×10^-4

decay constant for carbon-14:

  0.693/5730 ≈ 1.21×10^-4

Since 4.33×10^-4 is greater than 1.21×10^-4, the decay constant of radium-226 is larger than that of carbon-14.

_____

Additional comment

Taking the reciprocal of a positive number reverses the ordering:

  1600 < 5730

  1/1600 > 1/5730

The half-life of radium-226 is less than that of carbon-14, so its decay constant will be larger.

Explanation:

Magma contains dissolved gases, which provide the driving force that causes most volcanic eruptions. As magma rises towards the surface and pressure decreases, gases are released from the liquid portion of the magma (melt) and continue to travel upward, and are eventually released into the atmosphere.

Answer:

F = F2 - F1     where F is the net force upwards

F = 5 - (.5 * 9.8) = (5 - 4.9) N = .1 N

Since there is a net force in the upwards direction the rocket should experience an upwards acceleration.

When the effort force needed to lift an object using an ideal lever with a force advantage greater than 1,  The effort force is less than the lifting force. The correct option is b.

Force is the mechanical physical quantity. The force advantage is equivalent to the mechanical advantage equal to the ratio of output to the input force.

The force advantage is

F.A = lifting force / effort force

When the effort force is greater, FA is less than 1. When FA is greater than 1, definitely, the effort force is less.
