By definition, the density is given by:

D = \frac{m}{V}

Where,

m: Helium mass

V: helium volume

Clearing the mass we have:

m = VD

Transforming the volume to milliliters we have:

V = (6.3) * (1000) = 6300 mL

Then, replacing values:

m = (6300) * (1.79 * 10 ^ {-4})\\m = 1.1277 g

Answer:

The mass of helium that would take to fill the balloon is:

m = 1.1277 g

Two waves are superposed. one wave has an amplitude of 5 cm, and other has an amplitude of 4 cm. What is the resultant amplitude
Vsevolod [243]
If both waves have the same wavelength, then the amplitude of
their sum could be anything between 1 cm and 9 cm, depending
on the phase angle between them.

If the waves have different wavelengths, then the resultant is a beat
with an amplitude of 9 cm.

Explain how electric currents flow only in closed circuits​
Fed [463]

Answer:

The wires are connected to both terminals of the battery, so they form a closed loop. Most circuits have devices such as light bulbs that convert electrical energy to other forms of energy. ... When the switch is turned on, the circuit is closed and current can flow through it.
