Tech A says the leads on a multimeter are negative and positive. Tech B says the test leads on an oscilloscope that we normally

use are yellow, blue, and green. Who is correct?

Answer:

Tech B

Explanation:

An oscilloscope is a measuring instrument for electronics. It represents a graph of amplitude on the vertical axis and time on the horizontal axis. It is widely used by students, designers, engineers in the field of electronics. It is often complemented by a multimeter, a power supply and a function generator or arbitrary.

As usual:

The Temperature palette or lead uses grading to indicate the frequency of occurrence, with warm colors such as yellow indicating red / frequently occurring events and cold colors such as blue / green indicating rarely occurring events

The spectral palette or lead uses grading to indicate the frequency of occurrence with cold colors such as blue that indicate events that occur frequently and warm colors such as red that indicate events that occur rarely.

The normal Palette uses the default color channel (such as yellow for channel one), along with the gray scale to indicate the frequency of occurrence, where the events that occur frequently are bright.

1)Kenetic Energy is defined as energy which a body possesses by virtue of being in motion. 2)KE) is KE = 0.5 x mv2. Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position..

And I hope this helped :)

LuckyWell [14K]
I got you b, V(final)^2=V(initial+2acceleration*displacement
So this turns to (0m/s)^2=(50m/s)^2+2(9.8)(d) so just flip it all around to isolate d so you get
-(50m/s)^2/2(9.8) = d so you get roughly 12.7555 meters up

3 bulbs are in series and the same 3 bulbs are in parallel with the same battery. Which bulbs will be dimmer?
Marina86 [1]

3 bulbs are in series and if the same 3 bulbs are in parallel with the same battery then the bulbs that are connected in parallel  will be dimmer

<h3>What is power?</h3>

The rate of doing work is known as power. The Si unit of power is the watt.

Power =work/time

The mathematical expression for the electric power is as follows

P = VI  

The same current flows through both bulbs when they are connected in series. A greater voltage drop across the bulb with the higher resistance will result in higher power dissipation and brightness. In the case of the parallel combination, the bulb will be dimmer

Thus, If the same three bulbs are connected in series and parallel with the same battery, the parallelly connected bulbs will be dimmer, therefore the correct option is A

Heather drops a ball weighing 0.50kg a distance of 2.0m. If the speed of the ball right after it bounces is the same speed of th
ki77a [65]
The speed of the ball just before impact was v=√(2gh) = 6.26m/s.  The acceleration is twice this over the time (twice because the second speed is the same in the other direction, meaning the total change in speed is 2V)
a = 12.52/0.10 = 125.2m/s²
The force is F=ma, so F = 0.5kg·125.2m/s² = 62.6N

You're conducting a physics experiment on another planet. You drop a rock from a height of 2.1 m and it hits the ground 0.6 seco
umka21 [38]

The formula to use is the one that connects the acceleration,
the distance fallen, and the time spent falling:

         Distance = 1/2 a T² .

You said  2.1 meters in 0.6 second .

                                                         2.1 m              = 1/2 a  (0.6 sec)²

Multiply each side by  2 :                  4.2 m              =       a (0.6 sec)²

Divide each side by (0.6 sec)² =     (4.2/0.36) m/s² =        a

                                                         a = (11 and 2/3) m/s²

                                        (about 19% more than Earth's gravity)
