It is true to say that If a cable originates inside one building and leaves the building, the landlord loses control of that cable.
Cable originating from one building to another building will have total control by the landlord from which the cable have passed. Since cable passes from one building to another building in that case some part of cable is not inside the building due to that control over the cable is distributed between more than one type of landlords .Worms can be spread through means other than direct network .Now, when it passed between the two building, in that case if one landlord did some changes in some part of cable then that change will not be controlled by the landlord who live in other building.

Calculate the maximum height to which water could be squirted with the hose if it emerges from the nozzle at 16.2 m/s.
Answers
Answer:
The maximum height to which water could be squirted with the hose is 13.380 meters.
Explanation:
A line of current of a fluid can be explained sufficiently by Bernoulli's Theorem. In this case, the system can be simplified due to neglectance of changes in absolute pressure. Water is squirted with an initial speed and reaches its maximum height, where final speed is zero. That is to say:
\(\frac{v_{1}^{2}}{2\cdot g} +z_{1} = \frac{v_{2}^{2}}{2\cdot g} +z_{2}\)
Where:
\(z_{1}\), \(z_{2}\) - Initial and final height of water, measured in meters.
\(g\) - Gravitational acceleration, measured in meters per square second.
\(v_{1}\), \(v_{2}\) - Initial and final speed of water, measured in meters per second.
If \(z_{1} = 0\,m\), \(v_{1} = 16.2\,\frac{m}{s}\), \(v_{2} = 0\,\frac{m}{s}\) and \(g = 9.807\,\frac{m}{s^{2}}\), then:
\(z_{2} = \frac{v_{1}^{2}-v_{2}^{2}}{2\cdot g} +z_{1}\)
\(z_{2} = \frac{\left(16.2\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot \left(9.807\,\frac{m}{s^{2}} \right)} +0\,m\)
\(z_{2} = 13.380\,m\)
The maximum height to which water could be squirted with the hose is 13.380 meters.

Which car has the greater acceleration magnitude: car A that accelerates from 0 to 10 m/s in 50 m or car B that accelerates from 10 m/s to 20 m/s in 50 m
Answers
The car that has the greater acceleration magnitude is car B
Torricelli's theorem can be used to calculate the magnitude of an object's acceleration when the value of time is not known:
\(v^{2} = v_{0}^{2} + 2a\Delta S\)
Note that \(v\\\) is the final velocity value, \(v_{0}\) is the initial velocity value, \(a\) is the acceleration value, and \(\Delta S\) is the displacement.
Substituting the values given by the question in the formula, we have:
CAR A\(10^{2}= 0^{2}+2\times a \times 50\)
\(100 = 100a\)
\(a = 1m/s^{2}\)
2. CAR B
\(20^{2} = 10^{2} + 2\times a \times 50\)
\(400 = 100 + 100a\)
\(100a=300\)
\(a = 3m/s^{2}\)
So, comparing the two acceleration calculated above, it is assumed that the car has the greater acceleration magnitude is car B with \(3m/s^{2}\) comparing to \(1m/s^{2}\) of the car A.

8. A 60-ks gymnast is moving with a speed of 12.0 m/s when she lands on the ground during an
event. If she bends her knees upon contact with the ground, then she will increase the time of
collision by a factor of 20 - compared to if she keeps her knees stiff. What affect does this have
upon the force and the impulse that she experiences? Mark all that apply
a. Bending her knees will make the force 20 times greater.
b. Bending her knees will make the force 20 times smaller.
c. Bending her knees will make the impulse 20 times greater.
d. Bending her knees will make the impulse 20 times smaller.
e. Bending her knees will have no effect upon the impulse she experiences.
Answers
Answer:
B. Bending her knees will make the force 20 times smaller.
Explanation:
By the Impulse Theorem, we notice that the normal force from the ground to the gymnast counteract the intial linear momentum of the gymnast during a certain time until rest is reached. The impulse (\(Imp\)), measured in newton-second, is function of initial linear momentum, measured in kilogram-meters per second, only and, hence, remains constant. That is:
\(Imp = m\cdot v\) (1)
Where:
\(m\) - Mass of the gymnast, measured in kilograms.
\(v\) - Initial speed of the gymnast, measured in meters per second.
If we know that \(m = 60\,kg\) and \(v = 20\,\frac{m}{s}\), the impulse experimented by the gymnast is:
\(Imp = (60\,kg)\cdot\left(12\,\frac{m}{s} \right)\)
\(Imp = 720\,\frac{kg\cdot m}{s}\)
If the time of collision is increased by a factor of 20 by bending her knees, then normal force from the ground on the gymnast must be decrased by a factor of 20 in order to keep the impulse constant.
Therefore, the right answer is B.

Answers
Answer:
Because the half-life is as long as Earth has existed, virtually all rocks on Earth still have most of their uranium-238. So, measurements can easily be obtained.
Explanation:
exact answer from pluto/ edmentum
The significant part of the chemical composition of rocks is uranium. The half -life of uranium is close to the age of earth. Hence, by measuring the uranium content in rocks we can predict its age.
What is uranium?Uranium is 92nd element in periodic table. It is an actinide element. All the actinides are radioactive in which the most common is uranium. They all undergo radioactive decay process. Radioactive decay is a first order reaction. The rate constant K can be written as:
k = 1/t ln (W0/Wt)
where t is the tome of decay, W0 be the initial amount and Wt is the amount after time t.
here k = 0.693/t1/2
By this relation we can find t the age of a substance, if know the amounts and half life t1/2. Uranium is present in rocks and minerals. Uranium undergo nuclear decay and will forms its isotopes or new products.
Thus, by measuring the current amount of uranium in rocks by knowing the half life of uranium we can predict the age of rocks.

3)what is the maximum height the ball goes above the ground? 14.74m
I need help with 4,5 and 6
4)How far from where it was kicked will the ball land?
5) what is the speed of the ball 2.5 second after it was kicked?
6)how high above the ground is the ball 2.5 seconds after it is kicked?
Answers
The answers are 4. The distance from where the ball was kicked is 38.06 meters, 5. The speed of the ball 2.5 seconds after it was kicked is 13.82 m/s, and 6. The ball is 21.88 meters above the ground 2.5 seconds after it is kicked.
4) To calculate the distance from where the ball was kicked, we need to find the time it takes to reach the ground. We can use the fact that the vertical displacement of the ball is zero at the highest point. Using the formula vf = vi + at, the time it takes to reach maximum height is t = vf / g where g is the acceleration due to gravity which is -9.8 m/s² since it is downward and vf is the final velocity which is 0 because the ball comes to rest at the highest point. t = 17 / 9.8 = 1.73 s. This means the total time for the ball to hit the ground is 2 x 1.73 = 3.46 s. Using the formula for horizontal distance traveled d = vt, we get d = 11 x 3.46 = 38.06 m. So, the distance from where the ball was kicked will be 38.06 meters.5) To calculate the speed of the ball 2.5 seconds after it was kicked, we need to find the horizontal and vertical components of the velocity of the ball at 2.5 seconds. The horizontal component is constant, so it will still be 11 m/s. To find the vertical component, we use the formula vf = vi + at where vi is initial velocity, a is acceleration due to gravity which is -9.8 m/s² and t is the time which is 2.5 seconds. vf = 17 + (-9.8 x 2.5) = -7.5 m/s. Since the ball is moving downward, the velocity is negative. Therefore, the speed of the ball 2.5 seconds after it was kicked is sqrt(11² + (-7.5)²) = 13.82 m/s.6) To calculate how high above the ground is the ball 2.5 seconds after it is kicked, we use the formula for the displacement of an object in the vertical direction y = vi*t + (1/2)*a*t² where vi is initial velocity, a is acceleration due to gravity which is -9.8 m/s² and t is the time which is 2.5 seconds. y = 17*2.5 + (1/2)*(-9.8)*(2.5)² = 21.88 m. So, the ball is 21.88 m above the ground 2.5 seconds after it is kicked.For more questions on speed

Newton's second law we can find that the correct answer is:
E) It cannot be determiner whick block has more masses from the information provided
Newton's second law establishes the relationship between force, mass, and acceleration of a body. Since force and acceleration are vector quantities, their components must be added on each axis
For this problem we have two bodies, let's write Newton's second law for the body B, we assume that the body B descends
W_b - T = m_b a
W_b = m_b g
m_b - T = m_b a
Where W_b is the weight of block B, T the tension of the string, mb the mass of block b and the acceleration
Now let's find the relation for block A
let's set a datum with the x axis parallel to the ramp
T - Wₓ = mₐ a
sin θ = Wₓ / W
Wₓ = Wₐ sin θ
Wₐ = mₐ g
Where Wₓ is the component of the weight, Wₐ the weight of the body A and θ the angle of the plane
Let's write our system of equations
m_b g - T = m_b a
T - mₐ g sin θ = mₐ a
let's add the equations
g (m_b - mₐ sin θ) = (m_b + mₐ) a
a = \(\frac{m_b - m_a \ sin \ \theta}{m_b+m_a} \ g\)
Let's analyze this expression
The numerator is positive the body B descends, this occurs whenm_b - mₐ sin θ > 0
The numerator is negative, body B rises
m_b - mₐ sin θ <0
We can observe that the acceleration is positive or negative depending on the relation of the masses and the angle of the plane.

Additionally, at the critical temperature, the substance reaches its maximum vapor pressure, and any further increase in temperature and pressure will not cause it to change its state but only its density and hence, it cannot lose any more thermal energy from itself.

Answer:
Thats probably 11
Explanation:
A car travelling on a straight road initially at 54 km/h accelerates for 2.3 s at a constantacceleration of 8.2 m/s2. What is the car's final speed, in m/s?(Hint: You must first convert 54 km/h to m/s.)
Answers
Given:
The initial speed of the car is,
\(u=54\text{ km/h}\)The acceleration is,
\(a=8.2\text{ m/s}^2\)The time for which the car is travelling with acceleration is,
\(t=2.3\text{ s}\)To find:
The car's final speed
Explanation:
The initial speed of the car is,
\(\begin{gathered} u=54\text{ km/h} \\ =\frac{54\times1000}{3600}\text{ m/s} \\ =15\text{ m/s} \end{gathered}\)The final speed of the car is,
\(v=u+at\)Substituting the values we get,
\(\begin{gathered} v=15+8.2\times2.3 \\ =33.9\text{ m/s} \end{gathered}\)Hence, the final speed is 33.9 m/s.
