Answer:

Option (B)

Explanation:

In terms of communication, a receiver is usually referred to as a person who listens, reads as well as observes. In simple words, a receiver is an individual or it can be a group of individuals, to whom any type of message is being diverted. The other name for the receiver is 'audience'.

In the given condition, Warren is attending a seminar in which he is listening to the speaker, as a part of the audience. So, it can be concluded that Warren is a receiver who is receiving information or hearing the speaker.

Thus, the correct answer is option (B).

sashaice [31]

Answer:

539.5°

Explanation:

33.3 revolutions per minute

1 revolution = 360°

1 minute = 60 seconds

hence

33.3 revs ----> 1 minute = 60 seconds

X revs -----------> 2.70 seconds

X = (33.3 x 2.7)÷60 = 1.4985 revolutions in 2.70 seconds

1.4985 revolutions = 1.4985 x 360 = 539.46

which is approximately 539.5°

A force of 250 N is applied to an object that accelerates at a rate of 10m/sec2. What is the mass of the object?
Mrac [35]
F=ma. So if you have the Force and the Acceleration you can find the mass. m=F/a. So the mass is 25kg

What does conserving mass mean in a chemical equation?
mixas84 [53]

There is equal number of each type of atom on the reactant and product side.

<u>Explanation:</u>

Conserving mass in a chemical reaction means  balancing the conservation of mass through  the law and balancing the atoms. There is equal number of each type of atom on the reactant and product side.

There is an equal amount of atoms on both the sides that is the reactant side as well as the product side, it balances the atoms to have a conservation of mass, through the law of conservation of mass.

Using the law of conservation mass, a chemical reaction is balanced and has a conserved mass, when the reactant and the product side contain equal atoms.
