If an all electric house uses 2400 kWh in a month, what will the amount of the bill for electricity be at a rate of 9.5 cents pe
alexira [117]

Answer:

<h2>$228</h2>

Explanation:

Given data

Total electricity consumption = 2400 kWh

Rate of consumption = 9.5 cent per kWh

converting cent to dollar we have. 9.5/100= $0.095

hence the bill is 2400*0.095= $228

You rapidly swirl a mixture of substances with different densities
borishaifa [10]
Having different densities being swirled rapidly will cause sedimentation. Sedimentation is the segmentation of the mixture creating layers of particles of these different densities. The process of rapid swirling is called differential centrifugation. An example use of this method is separation human blood into, red, platelet and white blood cells.

The force of replusion between two like charged particles will increase if​
Alex_Xolod [135]

Answer:

The distance of separation is decreased

Explanation:

From Cuolomb's law, we know that the strength of charge is inversely proportional to the distance of separation between the charges. To mean that increasing the distance let's say from 2m to 3 m would mean initial strength getting form 1/4 to 1/9 which is a decrease. The vice versa is true hence the force of repulsion can increase only when we decrease the distance of separation.
