Hello, my name is Charlie.

On this is about science.

The atomic mass is most important because it tells you the charge of the atom. <span>Because from atomic mass number it came from periodic table.</span>

The answer is B.

Hope it helped you.

-Charlie

Have a great day!

What geological feature can be created by a divergent boundary

VARVARA [1.3K]

<span>Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to be dragged along in the direction of flow. At the crest of the uplift, the overlying plate is stretched thin, breaks and pulls apart. hope this helps

A traveler pulls on a suitcase strap at an angle 36° above the horizontal. If of work are done by the strap while moving the sui

ollegr [7]

Answer:

The tension in the strap is 74.82 N.

Explanation:

Given that,

Angle between the horizontal and the suitcase is 36 degrees.

The distance traveled by the suitcase is 15 meters.

Let the work done by the suitcase is 908 J. We know that the work done in the vector form is given by :

$W=Fd\ \cos\theta\\\\908=F\times 15\times cos(36)\\\\F=74.82\ N$

So, the tension in the strap is 74.82 N. Hence, this is the required solution.

An ac generator has a maximum emf output of 150 V. What is the rms current in the circuit when the generator is connected to a 3

natima [27]

This is an insidious question. Quite frankly, I would not have
expected to see it here on Brainly. But I'm ready to play the
cards that you have dealt me.

None of the choices offered is a correct solution.

If the output of the AC generator is nice and sinusoidal, and
its maximum (peak) emf is 150 volts, then its RMS emf is

   (1/2) (150) (√2) = 106.07 volts.

The resistor's dissipation is

   Power = (current) x (voltage) .

If the resistor is dissipating its full rated 35W, then

   35W = (current) x (106.07 V)

Divide each side by 106.07 V:

   RMS Current = (35W) / (106.07 V) = 0.33 Ampere .
_________________________________________

Looking over the choices offered . . .

The largest choice ... 3.1 A ... is the current in a resistor
that is dissipating 35W if the voltage is

   (35W / 3.1A) = 11.29 volts .

The smallest choice ... 1.2 A ... is the current in a resistor
that is dissipating 35W if the voltage is

   (35W / 1.2A) = 29.17 volts .

Whatever you meant the so-called "150 V" of the generator
to represent ... whether the RMS sinusoidal, peak sinusoidal,
peak square-wave, RMS square-wave, DC, average, etc. ...
none of the choices for current, in combination with any of these
generators, would dissipate 35W.
