The frontage measure is 45 feet.
FeetThe British imperial and American customary systems of measurement both use the feet (standard symbol: ft) as a unit of length. One foot has exactly 0.3048 meters since the International Yard and Pound Agreement of 1959. One yard equals three feet in both customary and imperial measurements. One foot equals 12 inches.
Throughout history, numerous regional systems of units, including the Greek, Roman, Chinese, French, and English systems, included the concept of "feet." Its length varied from one nation to another, from one city to another, and occasionally from one trade to another. Its length was often divided into 12 inches or 16 digits, however this was not always the case. Its typical length was between 250 mm and 335 mm.

formed at a divergent boundary
formed at a convergent boundary.
formed where mantle erupts through crust
Formed due to subduction, formed at a convergent boundary, and formed where mantle erupts through crust.
What is subduction?Subduction is the geologic process in which one tectonic plate moves beneath another and is forced downwards into the mantle. It is an important part of plate tectonics, as it is responsible for the formation of mountain ranges and volcanism. Subduction occurs at convergent boundaries, where two plates come together, and is usually accompanied by earthquakes, as the plates grind and slide against each other. Subduction zones are the areas where this process is occurring, and they are typically found in the world's oceans, along the margins of the continental plates.

An object with a weigh of 170 N on Earth i brought to planet Oobla. Where it ha a weight of 360 N. What i the gravitational field trength on Oobla
The gravitational field strength on Oobla is 20.8 N/kg. It is greater than the gravitational field strength on Earth.
What is the gravitational field strength?The gravitational field strength, also called acceleration due to gravity or free-fall acceleration, is the gravitational force that acts on a mass of object. It can be expressed as
g = F/m
Where
g = gravitational field strength (N/kg or m/s²)F = gravitational force or weight (N)m = mass of object (kg)The gravitational force can be stated as weight of object W. The formula becomes W = mg. So, the weight of an object depends on the gravitational field strength on a place.
An object has a weight of 170 N on Earth. The weight becomes 360 N on Oobla. Find the gravitational field strength on Oobla!
We know that the gravitational field strength on Earth is 9.8 N/kg.
Let's say:
W₁ = weight on Earthg₁ = gravitational field strength on EarthW₂ = weight on Ooblag₂ = gravitational field strength on OoblaThe mass of an object is always the same wherever it is.
So, the gravitational field strength on Oobla is
m = W/g
m₁ = m₂
W₁/g₁ = W₂/g₂
170/9.8 = 360/g₂
g₂ = (9.8×360)/170
g₂ = 20.8 N/kg
It is greater than the the value of g on Earth.
Hence, the planet Oobla has the gravitational field strength of 20.8 N/kg.

A stone is thrown horizontally with an initial speed of 10 m/s from the edge of a cliff. A stop watch measures the stone's trajectory time from the top of the cliff to the bottom to be 4. 3 s. What is the height of the cliff?.
By using kinematic equation, the height of the cliff would be 90.6 meters.
The kinematics equations are frequently used to analyze the free-falling motion of an object, in this case we are given that:
The time (t) = 4.3 seconds
Acceleration due to gravity (a) = 9.8 meters per second
Since we know that the time it takes for the stone to fall to the ground is 4.3 s, we can use the following formula to determine the height to which the stone will fall as a result of gravity:
x = v₀t + 1/2 at²
where x is the displacement, v is the velocity, t is the time, and a is the acceleration.
x = 0 + 1/2 (-9.8) (4.3)²
x = -90.6
As the result, the height of the cliff would be 90.6 meters.

At an equilibrium position of a pendulum, the velocity is at a maximum.
The pendulum hangs straight down while it is at rest, not swinging. This position is called the equilibrium position. It is practical to consider this position to be the origin or reference position indicated in the definition of position.
The pendulum's lowest point is where the equilibrium point is located. It is called this because, there are no forces acting on it. This is the point at which the pendulum would be at a stable, motionless equilibrium.

The required tension in the cable when the elevator accelerates down at a rate of 3. 7 m/s2 is 143163.26 N.
What is acceleration?The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

The change in thermal energy of the air in the balloon was 860 J
Calculate the specific heat capacity of the air in the balloon.
The specific heat capacity of the air in the balloon is 125.88 J/kg °C.
What is specific heat?Specific heat is the amount of energy required to raise the temperature of a unit mass of a substance by one degree. It is measured in joules per kilogram Kelvin (J/kgK). Specific heat is an important physical property of a substance, as it determines how much energy is required to change its temperature. It is also used to calculate the amount of energy released or absorbed during a chemical reaction. Specific heat is also known as heat capacity, and is often used to compare the heat capacity of different materials.
The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.
To calculate the specific heat capacity of the air in the balloon, we can use the equation:
Q = m * c * ΔT
Where Q is the change in thermal energy, m is the mass of the air, c is the specific heat capacity, and ΔT is the change in temperature.
Rearranging the equation, we get:
c = Q / (m * ΔT)
Plugging in the values given, we get:
c = 860 J / (0.00320 kg * 215 °C)
c = 860 J / (0.0068 kg °C)
c = 125.88 J/kg °C
Therefore, the specific heat capacity of the air in the balloon is 125.88 J/kg °C.

Quartz and halite have different crystal shapes primarily because of the internal arrangement of atom.
Due to some reasons, quartz and halite have different crystal shapes. Primarily, the reasons are:
Both are formed from molten material.Both are composed of minerals.Both are produced by heat and pressure.The very distinct key characteristics that make us can easily observe and differ between quartz and halite is that quartz crystals always make a pointed pencil shape. It has 6 sides on terminal ends as resembling a prism. Furthermore, halite tastes like salt, because halite is salt. The other characteristics that we could use to differentiate between two of them is that a quartz crystal is hexagonal in cross section, meanwhile a halite crystal is square in cross section.

A ball with a mass of 0.5 kilograms is lifted to a height of 2.0 meters and dropped. It bounces back to a height of 1.8 meters.
The energy of the ball has been reduced by
[ Select ]
(...)0.98 (...)8.82 (...)9.8 joules after bouncing back. This reduction happens because potential energy transforms to
[ Select ]
(...)kinetic (...)light (...)thermal energy.
Hint: Use PE = m × g × h where g = 9.8 m/s2.
The energy of the ball has been reduced by 0.98 joules (option A) after bouncing back because potential energy has been transformed into kinetic energy (option A).
What is potential and kinetic energy?Potential energy is the energy possessed by an object because of its position while kinetic energy is the energy possessed by an object because of its motion.
According to this question, a ball with a mass of 0.5 kg is lifted to a height of 2.0 meters and dropped. It bounces back to a height of 1.8 meters. The difference in potential energy can be calculated as follows:
P.E (1) = 0.5 × 2 × 9.8 = 9.8J
P.E (2) = 0.5 × 1.8 × 9.8 = 8.82J
∆P.E= 9.8 - 8.82 = 0.98J
This reduction occured because the potential energy of the ball changes to kinetic energy (in motion).
