According to the big bang theory, we live in a universe that is made of almost entirely of matter rather than antimatter because of a slight excess of matter over antimatter that occurred during the early universe.

This excess is thought to be due to a process called baryogenesis, which involves the production of baryons (such as protons and neutrons) from an initial state of pure energy during the first fractions of a second after the big bang.

The exact mechanism by which baryogenesis occurred is not well understood, but several possible theories have been proposed, including the idea that it is related to the violation of CP symmetry (which refers to the combination of charge conjugation and parity) in the early universe.

In any case, the slight excess of matter over antimatter meant that when matter and antimatter particles collided and annihilated each other during the early universe, there were more matter particles left over, which eventually led to the formation of the structures we see in the universe today.

The speed of the photon has been obtained as  8.9 * 10^5 m/s.

We know that the energy of the photon would be converted to the kinetic energy of the photon s it is moving. We would now go ahead to obtain the energy in joule.

We now have;

Energy in joules = 2.30 * 1.6 * 10^-19

= 3.68  * 10^-19 J

Then we know that;

KE = 1/2mv^2

KE = kinetic energy

m = mass of the electron

v = speed of the electron

Then

v^2= 2KE/m

v = √2KE/m

v = √2 *  3.68  * 10^-19/9.11 * 10^-31

Answer:

As the temperature increases, the kinetic energy of the molecules of the liquid increases.

Explanation:

Answer:

a = 1.5 m/s^2

Explanation:

Total force = 700 + 800 = 1500 N

then because   F = ma

                         1500 N  = 1000 kg  *  a

                                a = 1.5 m/s^2

The pressure shown on your tire gauge after driving on the freeway would be approximately 21.85 psi.

To determine the pressure in your car tires after driving on the freeway and experiencing a temperature change, we can use the ideal gas law, which states that:

PV = nRT

where:

P = pressure

V = volume

n = number of moles

R = ideal gas constant

T = temperature

Assuming the volume and the number of moles remain constant, we can rearrange the ideal gas law equation as:

P1/T1 = P2/T2

where P1 and T1 represent the initial pressure and temperature, and P2 and T2 represent the final pressure and temperature.

Given:

P1 = 20 psi (initial pressure)

T1 = 16 °C (initial temperature)

T2 = 40 °C (final temperature)

Converting temperatures to Kelvin:

T1 = 16 °C + 273.15 = 289.15 K

T2 = 40 °C + 273.15 = 313.15 K

Using the formula, we can calculate the final pressure (P2):

P2 = P1 * (T2 / T1)

P2 = 20 psi * (313.15 K / 289.15 K)

P2 ≈ 21.85 psi

Therefore, the pressure shown on your tire gauge after driving on the freeway would be approximately 21.85 psi.

The final speed of the car is 41.2064 m/s.  It covers 335.832 m during this acceleration.

Acceleration is the rate at which a velocity changes over time. It qualifies as a vector quantity because it possesses both direction and magnitude. Meter/second^2 (m/s^2) is the SI unit of acceleration.

Given that, acceleration of the car: a = 2.528 m/s².

Time intervals: t = 16.3 second.

Initial speed of the car = 0 m/s.

Hence, the final speed of the car is = acceleration × time interval

=  2.528 m/s² ×  16.3 second.

= 41.206 m/s.

And, the distance traveled = 1/2 × acceleration × time²

= 1/2 × 2.528 × 16.3² m

=335.832 m.

Hence, the final speed of the car is  41.206 m/s and  distance traveled is 335.832 m.

Answer:

The plane would need to travel at least \(8,\!580\; {\rm ft}\) (\(8.58 \times 10^{3}\; {\rm ft}\).)

The \(10,\!000\; {\rm ft}\) runway should be sufficient.

Explanation:

Convert unit of the the take-off velocity of this plane to \(\rm ft\cdot s^{-1}\):

\(\begin{aligned}v &= 180\; {\rm mph} \\ &= 180\; {\rm mi \cdot hrs^{-1}} \times \frac{1\; {\rm hrs}}{3600\; {\rm s}} \times \frac{5280\; {\rm ft}}{1\; {\rm mi}} \\ &= 264\; {\rm ft \cdot s^{-1}}\end{aligned}\).

Initial velocity of the plane: \(u = 0\; {\rm ft \cdot s^{-1}}\).

Take-off velocity of the plane \(v =264\; {\rm ft\cdot s^{-1}}\).

Let \(x\) denote the distance that the plane travelled along the runway. Since acceleration is constant but unknown, make use of the SUVAT equation \(x = ((u + v) / 2) \, t\).

Notice that this equation does not require the value of acceleration. Rather, this equation make use of the fact that the distance travelled (under constant acceleration) is equal to duration \(t\) times average velocity \((u + v) / 2\).

The distance that the plane need to cover would be:

\(\begin{aligned}x &= \left(\frac{u + v}{2}\right)\, t \\ &= \frac{0\; {\rm ft \cdot s^{-1}} + 264\; {\rm ft \cdot s^{-1}}}{2} \times 65.0\; {\rm s} \\ &= 8.58\times 10^{3}\; {\rm ft}\end{aligned}\).

The drag force on the skydiver at terminal velocity is 72.8 pounds.

This can be calculated by using the formula for drag force, which states that drag force is equal to the drag coefficient multiplied by the density of the fluid (in this case, air), multiplied by the velocity of the object squared, multiplied by the cross-sectional area of the object. At terminal velocity, the drag force acting on the skydiver is equal to the weight of the skydiver, which is 200 pounds. Therefore, the drag force on the skydiver is approximately 72.8 pounds.

Fd = 0.5 × ρ × Cd × A × V²

where Fd is the drag force, ρ is the density of air, Cd is the drag coefficient, A is the cross-sectional area of the skydiver, and V is the velocity.

Substituting the given velocity of 180 miles per hour (or 80.5 m/s) and solving for the drag force, we get:

Fd = 0.5 × 1.2 kg/m³ × 1.0 × 0.7 m² × (80.5 m/s)²

= 633 lbs

After opening the parachute, the cross-sectional area of the skydiver increases, which decreases the terminal velocity. Assuming the same drag coefficient and air density, but with a cross-sectional area of 4.6 m², we can use the same formula to find the new drag force at 10 miles per hour (or 4.47 m/s):

Fd' = 0.5 × 1.2 kg/m³ × 1.0 × 4.6 m² × (4.47 m/s)²

= 72.8 lbs

After opening the parachute, the skydiver experiences a significantly increased drag force, causing her to decelerate rapidly and reach a much slower terminal velocity of 10 miles per hour. The drag force increases because the cross-sectional area of the skydiver and parachute combination is much larger than just the skydiver alone, and the parachute also increases the drag coefficient.

A box experiences a varying net force that changes its velocity. Based on the description provided, it seems that the options (A) and (C) are the most relevant to the question.

Between 0 and 4:

The velocity of the box is increasing, which indicates that there is a positive acceleration.

Since the net force is causing an acceleration in the direction of motion, the net work done on the box is positive.

Therefore, the correct statement would be: Wnet > 0.

Between 1 and 12:

The velocity of the box is constant, which means there is no acceleration.

In this case, the net force acting on the box is zero.

When the net force is zero, no net work is done on the box.

Therefore, the correct statement would be: Wnet = 0.

Between 12 and 13:

The velocity of the box is decreasing, indicating a negative acceleration.

Since the net force is acting opposite to the direction of motion, the net work done on the box is negative.

Therefore, the correct statement would be: Wnet < 0.

Based on this analysis, the correct description would be:

Between 0 and 4: Wnet > 0

Between 1 and 12: Wnet = 0

The net gravitational force, Fₒᵤₜ, on a unit mass located on the outer surface of the Dyson sphere is zero.

Since the Dyson sphere is a complete shell surrounding a star, the gravitational forces exerted by the mass inside the shell cancel out due to symmetry.

According to the shell theorem, the gravitational force exerted by a spherically symmetric shell on a particle inside the shell is zero.

Therefore, when a unit mass is located on the outer surface of the Dyson sphere, the gravitational forces from all directions cancel out, resulting in a net gravitational force of zero.

This means that the unit mass will experience no gravitational attraction towards or away from the Dyson sphere. The cancellation of gravitational forces is a consequence of the uniform distribution of mass within the shell and the inverse square relationship of gravitational force with distance.

Therefore, the gravitational force acting on a unit mass positioned at the outer surface of the Dyson sphere is balanced and has a net value of zero.
