At room temperature and pressure, alcohol is in which state of matter? solid, liquid, gas, or plasma **not sure!

Answer:4.32Nm

Explanation:

The magnitude of the torque will be the product of the force and its perpendicular distance from the force.

Force = 27N

Perpendicular distance = 16cm = 0.16m

Torque = 27×0.16

Torque = 4.32Nm

Answer:

Option "D" is the correct answer i.e. Both Technicians A & B

Explanation:

Dear,

Loose wheel bearings can be caused on any machine.

The Following can be the reasons :

• the machine or motor is installed improperly
• the rotor(rotating part) of machine is not balanced
• the cover get deteriorated with time
• Bad manufacturer

So, when the bearings will be loose then the following can happen:

1. It will produce vibration in machine which can be judged by a vibration pen eg. SKF vibration pen
2. The vibration will also result in noise. You can check by
3. The machine winding if it is motor will burn-out.
4. Bush needs to be installed if the bearing runs loose.

Therefore,  "D" is right.

Answer:

fixed distances from the nucleus of an atom where electrons may be found

Explanation:

The direction of motion for aseries of wave fronts is represented with a ray. A ray is a line extendingoutward from the source representing the direction of propagation of the waveat any point along it. They are perpendicular to the wave fronts.

Answer:

The direction of motion for a series of wave fronts is represented with a(n) ray

Answer:

Change in gravitational potential energy of the chair is,

Explanation:

It is given that,

Mass of the chair, m = 12 kg

Distance of the second floor from the ground, h = 3.3 m

The position of ground at h = 0

Let is the change in gravitational potential energy of the chair. Initial potential f the chair is equal to 0.

or

So, the change in the gravitational potential energy of the chair is 390 joules.

Final answer:

The change in gravitational potential energy of the chair is +385 J.

Explanation:

The change in gravitational potential energy of the chair can be calculated using the formula ΔPE = mgh, where m is the mass of the chair, g is the acceleration due to gravity, and h is the change in height. In this case, the mass of the chair is 12 kg, the acceleration due to gravity is 9.8 m/s², and the change in height is 3.3 m. Plugging these values into the formula, we get ΔPE = (12 kg)(9.8 m/s²)(3.3 m) = 384.72 J. Therefore, the change in gravitational potential energy of the chair is approximately +385 J.
