Answer: ''A bin should be labeled “chemical wastes and broken glass.”

Explanation:

The waste disposal is issue is the primary concern for the laboratory staff or others who daily work in labs. It should be done with utmost precaution and care.

Among the options given, ''A bin should be labeled “chemical wastes and broken glass.” is the correct option. This is because of the fact that chemical wastes can be hazardous. They can catch fire with air or may cause burns and injury if they accidentally come in contact with the skin. The broken glass may exhibit sharp edges which can be injurious. Therefore, the bin which contains either chemical wastes or broken glass must be labelled properly so as prevent hazards and injuries in the laboratory.

Which of the following statements about Ohm's Law is true? A. Increasing the voltage decreases current. B. Keeping the same volt
Luden [163]

The correct answer is option D

The Ohm's Law states that current passing through a conductor is directly proportional to the voltage across the conductor.

Current =voltage/ resistance

The resistance causes hindrance in the path of the current and does not allows it to flow so, we must reduce the resistance to increase the flow of current in the conducting wire.

ahrayia [7]

Explanation:

The question is not complete, here is the complete question

<em>"Beatrice and the Elevator Beatrice, a middle school student, is visiting a very tall office building and notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is traveling down. After making these observations, Beatrice comes back to the building and stands on a bathroom scale that measures her weight as she travels up and down in the elevator.</em>

<em>1. . What question is Beatrice trying to answer?</em>

<em>2. What is one variable Beatrice could change in her investigation? What might she figure out if this </em>

<em> variable was changed"</em>

1. Beatrice is trying to observe the influence of the elevator movement on her weight, Hence the question is<em> "will the elevator  movement cause her weight to change"</em>

therefore moving upward the reading on the scale will increase

Reading=mg+ma

downward

Reading will reduce

Reading=mg-ma

2. The independent variable is the acceleration due to gravity g=9.81m/s^2

while the dependent variables are

    i. The elevators acceleration

    ii. Beatrice's mass

A disk-shaped platform has a known rotational inertia ID. The platform is mounted on a fixed axle and rotates in a horizontal pl
Zarrin [17]

Answer:

Explanation:

The angular momentum of that same disk-sphere remains unchanged the very same way before and after the impact of the collision when the clay sphere adheres to the disk.

 \mathbf{I_w} = constant.

The overall value of such moment of inertia is now altered when the clay spherical sticks. Due to the inclusion of the clay sphere, the moment of inertia will essentially rise. As a result of this increase, the angular speed w decreases in value.

Recall that:

The Kinetic energy is given by:

\mathbf{K = \dfrac{1}{2} Iw^2} \\ \\\mathbf{K = \dfrac{1}{2} lw*w}

where;

\mathbf{I_w} is constant and w reduces;

As a result, just after the collision, the system's total kinetic energy decreases.

In the diagram below, if A's magnitude is 16 N and B's is 25 N, what is the magnitude of C?
morpeh [17]
Assuming that’s a right triangle, in this case A^2 + C^2 = B^2 … (16)^2 + C^2 = (25)^2 … C = 19.2 N
