When the pulling force is first applied, the cannula doesn't move because of the static friction. After a while, at a certain amount of applied force, friction increases until the limit reached its threshold for the motion.

Friction is the force that resists the sliding motion between two surfaces. It can be kinetic or static. Static friction happens when the two surfaces don't slide because the amount of static friction fully counteracts an applied force. It happens until the upper limit is reached, which will happen when one applied enough amount of force to the surface. Once the upper limit is reached, the surfaces will start to slide against each other, in which the static friction becomes kinetic friction.

I cant explain it but when i asked my teacher thats what he told me

You are running 4.2 m/s along a tall roof top. You have 590,646 Joules of mechanical energy and have a mass of 300 kg. The building is 200 meter tall.

Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.

kinetic energy + potential energy = mechanical energy

Kinetic energy = \(\frac{1}{2} mv^{2}\) = 2646 joule

potential energy = ME - KE

P E = 590646 - 2646 = 588000 Joule

P E = mgh

h = P E / mg

h = 200 meter

Answer: make objective observations.

Explanation:

Answer: Objective Observations

Explanation: The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false.

According to Heisenberg's Uncertainty Principle, it is impossible to determine the position and momentum of a particle with absolute certainty at the same time. The Uncertainty Principle is defined as Δx * Δp ≥ h/4π, where Δx is the uncertainty in position, Δp is the uncertainty in momentum, and h is Planck's constant.
For the given problem, the uncertainty in position of a proton with mass 1.673 x 10-27 kg and kinetic energy 1.2 keV can be calculated as follows:

We know that the momentum p of a particle is given by p = mv, where m is the mass of the particle and v is its velocity.
The kinetic energy of the proton can be converted to momentum using the equation E = p²/2m, where E is the kinetic energy.
1.2 keV = (p²/2m)    (1 eV = 1.6 x 10^-19 J)
p²/2m = 1.92 x 10^-16 J
The momentum p of the proton can be calculated by taking the square root of both sides:
p = √(2mE) = √(2 x 1.673 x 10^-27 x 1.6 x 10^-16) = 7.84 x 10^-22 kg m/s

Using Heisenberg's Uncertainty Principle, we can calculate the uncertainty in position as follows:
Δx * Δp ≥ h/4π
Δx ≥ h/4πΔp
Substituting the values of h, Δp, and solving for Δx:
Δx ≥ (6.626 x 10^-34)/(4π x 7.84 x 10^-22)
Δx ≥ 2.69 x 10^-12 m

Therefore, the uncertainty in position of the proton is 2.69 x 10^-12 m.

Explanation:

In an emergency situation where the electricity needs to be shut off in a science classroom, it is essential to have a design that allows for quick and easy access to the electrical outlets. One option could be to install a master power switch that controls the power supply to all the lab stations in the classroom.

This switch should be located in a prominent and easily accessible location, such as near the classroom entrance or by the teacher's desk.

Another option could be to use individual power strips for each lab station, but with a centrally located main power switch that controls all of the power strips. This would allow for a more flexible setup and easier access to the power supply in case of an emergency. In this case, it is important to ensure that the power strips are rated for the maximum electrical load that the lab equipment may require.

Regardless of the design chosen, it is important to ensure that the emergency shut-off switch or power strip is clearly marked and easily identifiable, so that in an emergency situation, anyone can quickly and easily turn off the power to the lab stations.

Additionally, it is important to have clear protocols and procedures in place for shutting off the power supply in the event of an emergency, and to ensure that all students and staff are trained on these protocols.

Answer:

The relative velocity of the motorcycle to a passenger in the car is 30 km/h

Explanation:

The question relates to the principle of relative velocity and reference frames

The given parameters are;

The velocity of the motorcycle, v₁ = 120 km/h

The velocity of the car, v₂ = 90 km/h

The relative velocity of an object X with regards to another object Y is the velocity the object X will seem to be moving with to an observer in the rest frame of object Y written as \(\underset{v}{\rightarrow}_{X|Y}\) = \(\underset{v}{\rightarrow}_{X}\) - \(\underset{v}{\rightarrow}_{Y}\)

Therefore, the relative velocity of the motorcycle to the car is \(v_{1|2}\) = v₁ -  v₂, which give;

\(v_{1|2}\)  = 120 km/h - 90 km/h = 30 km/h

The relative velocity of the motorcycle to a passenger in the car = 30 km/h.

Hurricanes are the enormous storms which come with a rotating wind speed of about 74 miles per hour. The rotating wind that swirls across the warm water of the tropics and also comes with a terrifying force.

The Coriolis force is an inertial or the fictitious force, which acts on the objects which are in motion within a frame of reference that rotates them with respect to an inertial frame. In a reference frame, with the clockwise rotation, the force acts to the left of the motion of the object. Whereas, in one with anticlockwise or counterclockwise rotation, the force acts to the right of the object. The deflection of an object due to this Coriolis force is called as the Coriolis effect.

The optimal values of \(q_1\) and \(q_2\) are determined by these equations, which are functions of Michael's income and the prices of the goods.

The given problem describes Michael's utility maximization problem with a constant elasticity of substitution (CES) utility function. The objective is to find the optimal values of \(q_1\) and \(q_2\) in terms of Michael's income (Y) and the prices of the two goods (\(p_1\) and \(p_2\)).

1. Substitute the income constraint into Michael's utility function:

\(U(q_1, q_2) = (q_1^\rho + q_2^\rho)^(1/\rho)\)

  s.t. \(Y = p_1q_1 + p_2q_2\)

  We can rewrite Michael's budget constraint as \(q_2 = (Y - p_1q_1)/p_2\). Substituting this expression into his utility function, we have:

 \(U(q_1, p_2, Y) = (q_1^\rho + [p_2(Y - p_1q_1)/p_2]^\rho)^{(1/\rho)\)

  By making this substitution, we have converted the constrained maximization problem with two control variables (\(q_1\) and \(q_2\)) into an unconstrained problem with one control variable \((q_1)\).

2. Use the standard unconstrained maximization approach to determine the optimal value for \(q_1\). To obtain the first-order condition, we differentiate the utility function with respect to \(q_1\) and set it equal to zero:

\(\delta U / \delta q_1 = \rho(q_1^{(\rho-1)} + \rho[p_2(Y - p_1q_1)/p_2]^{(\rho-1)}(-p_1/p_2)) = 0\)

Simplifying and solving for \(q_1\):

\(\rho q_1^{(\rho-1)} - \rho(p_1/p_2)[p_2(Y - p_1q_1)/p_2]^{(\rho-1)} = 0\)

\(\rho q_1^{(\rho-1)} - \rho(p_1/p_2)[Y - p_1q_1]^{(\rho-1)} = 0\)

\(\rho q_1^{(\rho-1)} = \rho(p_1/p_2)[Y - p_1q_1]^{(\rho-1)}\)

\(q_1^{(\rho-1)} = (p_1/p_2)[Y - p_1q_1]^{(\rho-1)\)

\(q_1^{(\rho-1)} = (p_1/p_2)^{(1-\rho)}[Y - p_1q_1]^{(\rho-1)}\)

\(q_1^{(\rho-1)} = (p_1/p_2)^{(1-\rho)}(Y - p_1q_1)^{(\rho-1)}\)

\(q_1^{(\rho-1)} = (p_1/p_2)^{(1-\rho)}(Y^{(\rho-1)} - (\rho-1)p_1q_1(Y - p_1q_1)^{(\rho-2)})\)

  This equation represents Michael's optimal \(q_1\) as a function of his income (Y) and the prices (\(p_1\) and \(p_2\)).

3. Similarly, we can derive a similar expression for his optimal \(q_2\):

\(q_2^{(\rho-1)} = (p_2/p_1)^(1-\rho)(Y^{(\rho-1)} - (\rho-1)p_2q_2(Y - p_1q_2)^{(\rho-2)})\)

  This equation represents Michael's optimal \(q_2\) as a function of his income (Y) and the prices (\(p_1\) and \(p_2\)).

Therefore, these equations, which depend on Michael's income and the prices of the commodities, determine the ideal values of \(q_1\) and \(q_2\).

To find angle A, we can use the cosine law, which states that $a^2 = b^2 + c^2 - 2bc \cos{A}$. We have $b=5.3$, $c=7$, and $a=8.2$, so we can plug in and solve for $\cos{A}$:$$8.2^2 = 5.3^2 + 7^2 - 2(5.3)(7) \cos{A}$$$$\cos{A} = \frac{8.2^2 - 5.3^2 - 7^2}{-2(5.3)(7)} = 0.509$$$$A = \cos^{-1}{(0.509)} \approx 43.29^\circ$$The length of side x using the appropriate sine X is 61.32 units.

We can use the sine law, which states that $\frac{a}{\sin{A}} = \frac{b}{\sin{B}} = \frac{c}{\sin{C}}$. We know that $A=101^\circ$ and $a=x$, so we can use the ratio $\frac{a}{\sin{A}}$ to solve for $x$:$$\frac{x}{\sin{101}} = \frac{c}{\sin{38}}$$$$x = \sin{101} \cdot \frac{c}{\sin{38}} \approx 61.32$$Therefore, the length of side x is approximately 61.32 units.
