a 1010 W radiant heater is constructed to operate at 115 V. (a) What is the current in the heater when the unit is operating?
scZoUnD [109]

Answer:

<h2>8.78 Amps</h2>

Explanation:

Given data:

power rating of the heater P= 1010 W

voltage of the heater V= 115 volts

current taken by the heater I= ?

We can apply the power formula to solve for the current in the heater

i.e P= IV

Making I the current subject of formula we have

I= P/V

Substituting our given data into the expression for I we have

I=1010/115= 8.78 A

<h2 /><h2><em>Hence the current when the unit/heater is operating is 8.78 Amp</em></h2>

Hair color is a trait that’s controlled by many genes working together. Each gene contributes to this trait only in a small prop
Anna35 [415]
The correct answer should be polygenic inheritance

Most genes that affect the way a human being looks have been inherited in this way. Not only hair but also things like height and weight, eye color, and similar.

Refer to Activity 1: Describe the difference between the rate of diffusion seen for urea and albumin
raketka [301]

Answer:

the major difference between the rate of diffusion between urea and albumin is that urea diffused more slowly because it is larger than albumin.

Explanation:

As described in activity 1, the major difference between the rate of diffusion between urea and albumin is that urea diffused more slowly because it is larger than albumin. Urea basically is an heavy compound, thus it is at the base of the chain reactions  which which major purpose is to break down the amino acids that make up proteins. Albumin on the other hand is a form of protein that simply helps in the transmission of blood and prevent blood from flowing through to other tissue in the body. The liver produces the albumin the body. So going back to the question, the major difference between the rate of diffusion between urea and albumin is that urea diffused more slowly because it is larger than albumin.
