The average speed of driving the 10 miles would be lower than 35 mph.

The average speed of an object is the ratio of the total distance to the total time of motion of an object.

Mathematically, average speed of an object is given as;

v(average) = total distance / total time

The average speed of a car decreases with increase in the total time of motion.

Due to the many stop lights along the drive, the total of motion of the car will increase will the total distance traveled by the car (10 miles) will be constant.

Also, since the speed limit is 35 mph, the average speed of the car will lower than the 35 mph speed limit.

Thus, the average speed of driving the 10 miles would be lower than 35 mph.

By using uniform motion, the average force is 3106.89 N.

We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule

vt = vo + a . t

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.

From the question above, we know that

vo = 0 m/s

vt = 10.6 m/s

m = 0.85 kg

t = 2.9 ms = 2.9 x 10¯³ second

Find the acceleration by using the first equation

vt = vo + a . t

10.6 = 0 + a. 2.9 x 10¯³

a = 3655.17 m/s²

In order to make his measurements for determining the Earth-Sun distance, Aristarchus waited for the Moon's phase to be exactly half full while the Sun was still visible in the sky. For this reason, he chose the time of a half (quarter) moon.

It was now possible for another Greek astronomer, Aristarchus, to attempt to determine the Earth's distance from the Sun after learning the distance to the Moon. Aristarchus discovered that the Moon, the Earth, and the Sun formed a right triangle when they were all equally illuminated. Now that he was aware of the distance between the Earth and the Moon, all he needed to know to calculate the Sun's distance was the current angle between the Moon and the Sun. It was a wonderful argument that was weakened by scant evidence. Aristarchus calculated this angle to be 87 degrees using only his eyes, which was not far off from the actual number of 89.83 degrees. But when there are significant distances involved, even slight inaccuracies might suddenly become significant. His outcome was more than a thousand times off.

The difference in air pressure between the second floor and the top floor of a building is about equal to (1.2)(10)(100) = 1200 N/m2, where air density is equal to 1.2 kg/m3 and gravity acceleration is equal to 10 m/s2.

In physics, gravitational acceleration refers to the speed at which a body falls freely in a vacuum (and thus without experiencing drag). This is the constant acceleration brought on just by the gravitational pull. Gravimetry is the measurement and analysis of these rates. All bodies accelerate at the same rate in vacuum, independent of their masses or compositions.

The combined effects of gravity and the centrifugal force from Earth's rotation cause the Earth's gravity to be as great as it is at a given location on the surface. Depending on height, latitude, and longitude, the free fall acceleration varies at various locations on the surface of the Earth from 9.764 to 9.834 m/s2 (32.03 to 32.26 ft/s2). The exact definition of a conventional standard value is 9.80665 m/s2 (32.1740 ft/s2). Gravity anomalies are areas where this value differs significantly.

The electric flux is zero through four cube surfaces.

Assuming the charged filament is quite long, and you are not near the edges, the two opposing sides that the filament travels through have no flux. If the charge filament is long, which you may assume is indefinitely long, then there is the equal amount of charge on the left and right of where you are, therefore the electric field has no preference for left or right.

This implies that the electric field can only travel in or out of the filament. No field lines run through the two faces of the cube that the filament goes through if the electric field is not moving left or right. There are electric field lines on the four sides of the filament.

In order to achieve the desired resistance under the given circumstances, we would connect two 10 Ohms resistors in parallel and then connect it in series with a 3 Ohms resistors.

Mathematically, the total equivalence resistance of two resistors that are connected in parallel is given by:

1/Rt = 1/R₁ + 1/R₂

1/Rt = 1/10 + 1/10

1/Rt = 2/10

1/Rt = 1/5

Rt = 5 Ohms.

Next, we would connect this 5 Ohms resistor in series with the 3 Ohms resistor:

The kinetic energy of the muon is 4.08 MeV

Given that:

A pion (mπ = 273 me)

muon (mµ= 207me)

Neutrino (mv=0)

(Let’s assume that c =1, and that me= 0.511MeV)

Since the pion is at rest conversation of momentum dictates that the momenta of the muon and the neutrino be equal in magnitude,

P_μ=P_v      (1)

Since the pion is at rest its energy equals its mass, E_π=m_π. Since the neutrino is massless its energy equals its momentum E_v=P_v . By conservation of energy,

E_π=E_μ+E_v, so

E_μ=m_π-P_v     (2)

Substituting the right sides of (1) and (2) into the left side of the fundamental kinematic equation for the muon E_μ^2-P_μ^2=m_μ^2 yields

〖(m_π-P_v)〗^2-P_μ^2=m_μ^2

Solving for P_v gives (the magnitudes of) the momenta of the decay particles and the kinetic energy (equal to the total energy) of the massless neutrino,

P_v (〖=P〗_u=E_v )=((m_π^2-m_μ^2))/(2m_π )

P_v=(〖273〗^2-〖207〗^2)/(2× 273)=29.65 MeV
