Answer:

V = 8 R  

Step-by-step explanation:

The Ohm's law gives the relationship between the voltage, current and the resistance of the circuit. The mathematical relation is given by :

V = I R........(1)

I is current in amperes

R is resistance in ohms

V is voltage in volts

Current needed by the vacuum cleaner, I = 8 A

Put the value of I in equation (1) as :

V=8\times R

or

V = 8 R

So, the correct equation that is used to determine the voltage for a given amount of resistance is (c).

Select the postulate of equality or inequality that is illustrated.
Tcecarenko [31]

Answer: B) Comparison Postulate

This is the idea where if we had two numbers A and B, then we have the three possibilities

  • A < B
  • A = B
  • A > B

We can only pick one item that is true at a time.

In this case, 3+2 simplifies to 5, so 3+2 = 5 is true while 3+2 > 5 is not true.

3+2 > 5 simplifies to 5 > 5, and there's no way a number is larger than itself.

The product of two consecutive room numbers is 342. Find the room numbers.
Paraphin [41]
To determine this easily, figure out what two numbers will make a product ending with "2", (4 & 3, 8 & 9)
Since the square root of 625 is 25, it is obviously less than 25.
I used 18 and 19, and they are the correct answer.
