the brakes of a car are applied when it is moving at 110 km/h and provide a constant deceleration of meters per second per second (). how far does the car travel before coming to a stop?
The required distance car travels in a constant deceleration before coming to a stop is 46.70 m.
The speed of the car is given as 110 km/h.
Deceleration of the car is said to be 10 m/s².
⇒ a = - 10 m/s²
Let us convert km/h to m/s.
110 km/hr = 110 × 5/18 = 30.56 m/s
Initial velocity of the car u = 0 m/s
Now, to find out distance, let us pick the correct equation of motion which suits the information about the car.
v² - u² = 2 a s
where, v is final velocity
u is initial velocity
a is acceleration
s is distance
So, putting the known values into the above equation, we have,
v² - u² = 2 a s
(30.56)² - 0 = 2 × (-10) × s
-20 s = 933.91
s = -46.70 m
Negative sign indicates that the motion is in opposite direction.
Thus, the required distance car travels before coming to a stop is 46.70 m.
The question is incomplete. The complete question is 'The brakes of a car are applied when it is moving at 100 km/h and provide a constant deceleration of 10 meters per second per second (m/s2). How far does the car travel before coming to a stop.'

How much is 9 degrees Celsius in Fahrenheit?
9 degrees Celsius is 41 degree Fahrenheit
What does "temperature" mean?
Temperature is a unit used to represent hotness or coolness on any of a number of scales, including Fahrenheit and Celsius. Most places in the globe measure temperature using the Celsius system (°C). The boiling point of water is 100 °C, and its zero point is the freezing point of water, both at atmospheric pressure at sea level. This scale is empirical and was historically constructed. Because of the 100-degree interval, it was given the name centigrade scale. Since the kelvin was standardized in the International System of Units, it has been redefined in terms of the equivalent fixing points on the kelvin scale.
As a result, an increase in temperature of one degree Celsius is equivalent to an increase of one kelvin, even though the scales are numerically offset by precisely 273.15. In the US, people frequently utilize the Fahrenheit scale. At air pressure equal to that at sea level, water freezes at 32 °F and boils at 212 °F.
°C + 32 is °F
So 9°C will be 41°F

if v in r 3 and v · v = 0, then v is the zero vector. is it true or false? explain your answer.
The statement, v in r 3 and v · v = 0, then v is the zero vector, is true.
In linear algebra, a vector v in R^3 (which means a 3-dimensional real vector space) is said to be a zero vector if all its components are equal to zero. This vector is also known as the null vector or null element and is denoted by the symbol 0.
The dot product of two vectors, denoted by v · v, is a scalar quantity that measures the cosine of the angle between two vectors. If the dot product of a vector with itself is equal to zero, it means that the cosine of the angle between the two vectors is zero, which implies that the two vectors are orthogonal (i.e., they are at right angles to each other).
Therefore, if v · v = 0, it follows that the vector v is orthogonal to itself, which is possible only if all its components are equal to zero. Hence, in this case, v must be the zero vector.

Describe the orbit with r_max fixed but l very small. What is the semimajor axis a?
The orbit with r_max fixed but l very small is a parabola. The semimajor axis a is r_max.
What is the orbit ?An orbit is the path of a celestial object or spacecraft around a star, planet, or moon. The path is usually elliptical in shape, and a celestial object's orbital speed varies depending on its distance from the central body. An object's orbital period, or the amount of time it takes to complete one full orbit, is determined by the size of its orbit and its distance from the central body. The gravitational force of the central body affects the path of an object's orbit, and the orbital speed of the object is determined by the gravitational force and the distance of the object from the central body.
Using equations (8.48) and (8.50), we can rewrite the eccentricity of the elliptical orbit as:

what length of a cylindrical piece of tungsten wire having a radius of 3.79 mm has a mass of 39.7 g? the density of tungsten is 19.25 g/cm3 and volume = πr2h.
The length of the tungsten wire is 13.7 cm.
To find the length of the tungsten wire, we need to first find its volume. We know the density of tungsten, which is 19.25 g/cm³, and the mass, which is 39.7 g. We can use the formula for the volume of a cylinder, which is πr²h, where r is the radius and h is the height (which is equal to the length of the wire in this case).
First, we'll find the volume:
V = πr²h
V = π (3.79 mm)²h
V = 11.05 mm³h
Next, we'll convert the volume to cubic centimeters (cm³):
11.05 mm³ = 11.05 x 10^-9 cm³
Now that we have the volume in cm³, we can use the density formula to find the mass:
m = ρV
m = 19.25 g/cm³ x 11.05 x 10^-9 cm³
m = 0.2103 g
Finally, we'll use the mass and density to find the length:
m = ρV
0.2103 g = 19.25 g/cm³ x V
V = 0.2103 g / 19.25 g/cm³
V = 0.0109 cm³
And since the volume is equal to πr²h, we can find the height (which is the length of the wire) by rearranging the formula:
V = πr²h
h = V / πr²
h = 0.0109 cm³ / π (3.79 mm)²
h = 13.7 cm
So the length of the tungsten wire is 13.7 cm.

two cars are driving towards an intersection from perpendicular directions. the first car's velocity is 2 22 meters per second and the second car's velocity is 9 99 meters per second. at a certain instant, the first car is 8 88 meters from the intersection and the second car is 6 66 meters from the intersection. what is the rate of change of the distance between the cars at that instant (in meters per second)?
The rate of change of distance between the two bodies is -7m/s
Given:
The first car's velocity is 2m/s
The second car's velocity is 9m/s.
At a certain time, the first car is 8m from the intersection
And at the same time, the second car is 6m from the intersection.
The rate of change of distance, i.e dx/dt, which is the speed of the car.
Using Pythagoras' theorem, their distance apart is given as
Z²=X²+Y²
Z²=6²+8²
Z²=36+64
Z²=100
Z=√100
Z=10m
Let's assume the direction,
Let's assume the first car is moving in the positive x direction, then
dx/dt=2m/s
And also the second car will be moving in a negative y direction
dy/dt=-9m/s
Now, to know dz/dt, let's use the Pythagoras formulae above
x²+y²=z²
differentiate with respect to t
[tex]2dx/dt+2dy/dt=2dz/dt\\Divide through by 2\\dz/dt=dx/dt+dy/dt\\dz/dt=2-9\\dz/dt=-7m/s[/tex]
What is the Pythagorean theorem theory?
Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

What is open circuit output?
Answer:
A circuit in which the continuity is broken due to which the electric current can not flow is known as the open circuit. In an open circuit, the current flowing is zero, thus no power dissipates from an open circuit.
Explanation:
You're welcome.
A unipolar output whose sole connection to a supply voltage is made by an active component, often a transistor, within the integrated circuit is termed as the open circuit output.
What is defined as the open circuit output?When the active device is turned on, the output voltage reaches the supply voltage to which it is connected (via into the active device);
because when device is turned off, the output impedance for any other integrated circuit terminal is high, and the output voltage is ascertained by external circuit that the output is connected.Output are typically categorized in accordance with the name of the active device component within in the integrated circuit to which they are attached, for example, open-collector output, expansive output, etc.
Thus, a unipolar output whose sole connection to a supply voltage is made by an active component, often a transistor, within the integrated circuit.
