Answer:

B) 20 A

Explanation:

VOM full form is Volt Ohm milliammeter. It indicates that voltage, resistance and the current can be measured using this device. When the variations are very rapid , analog VOM is used instead of a digital VOM.

Using this current ( both A C and DC) can be measured in amperes.

Though the accuracy given by digital devices are more accurate, to identify changes in the circuit being tested and for trouble shooting, analog meters are more preferred.

Answer:

The type of interference the person perceives is a Constructive Interference

Explanation:

Before we solve the problem we need to clarify some concepts:

There are two types of Interference, the Constructive and the Destructive interference

The Constructive Interference happens if the difference between the waves movement is equal to an even semi-wavelength number

The Destructive Interference is the opposite than the Constructive Interference, it happens if the difference between the waves movement is equal to an odd semi-wavelength number

Taking the above into account let´s proceed to solve the problem.

First, we will need to find how much the wavelength is (we will call it l), we know the frequency f=200Hz, we also know the speed of sound is v=330m/s. We will use the next equation:

$l=v/f$ then we get that $l=1.65m$

In order to find the semi-wavelength we must divide by 2 the previous result, in this case the semi-wavelength will be:

$l/2=0.825m$

Now, we find the difference between the waves movement, which is the difference between both distances, this difference will be called d and we will find it this way:

$d=4.95m-1.65m$ then d=3.3m

After this, we will do a relation between the distance and the semi-wavelength in order to find what type of interference the person perceives, this way:

$(d)/(l/2)$ then, we have a relation equals to 4. As it´s an even number, we determine the interference is a Constructive Interference

What is the period of a wave with the wave speed of 12m/s and a frequency of 60 hz?

aleksklad [387]

To determine the period of a wave you need not utilize the value for the wave speed.

The formula for the period is T= 1/f
T stands for period/time while f is for frequency. Substitute the value for the frequency which is 60 Hz. That would give you:

T= 1/60 Hz

convert Hz to cycles per second to extract the unit of time (s).

60 Hz x 1/s/1 Hz= 60/s

To continue the computation:

T=1/60/s that will give you a T= 0.017 s or 17 ms.

Answer:

All soft drinks contain water. When soft drink bottles are chilled in sub-zero temperatures, the water on account of its anomalous expansion expands. Thus, to provide space for expanding water, soft drink bottles are not completely filled as otherwise they will burst.

Which force is represented by the arrow at A?

Tanzania [10]

Answer:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

The normal force is the force that surfaces exert to prevent solid objects from passing through each other. Normal force is a contact force. If two surfaces are not in contact, they can't exert a normal force on each other.The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
