An electric heater has a resistance of 15 ohms and is connected to a 120 volt circuit. What how many amps are in the circuit?

Answers

Answer 1

Answer:

Explanation:

Ohm's Law

V = I*R

I = current = amps

I = V/R

I = 120/15

I = 8A

Answer 2

Let's see

Current =I

Using ohm's law

V=IR120=15II=8A

Stripping tools designed for solid wire cannot be used on stranded wire. Why?

Answers

Answer:

One reason why stripping tool designed for use with solid wire cannot be used on stranded wire is that the diameter of a stranded wire is larger than the diameter of a solid wire of the same gauge.

Therefore, a tool for stripping a 8-gauge solid wire cannot be used for stripping a 8-gauge stranded wire as the diameter of an American Wire Gauge, AWG 8-guage solid wire (0.129 inches in diameter) is smaller than the diameter of an AWG 8-gauge stranded wire (0.152 inches in diameter)

Technician A says that the gear ratios in the transmission give the vehicle an extended operating range.
Technician B says that the final drive assembly has various gear ratios that can be selected with a
gearshift lever. Who is correct?
Select one:
O a. Technician A
O b. Technician B
O c. Both A and B
O d. Neither A nor B

Answers

Based on the fact that Technician A says that the gear ratios in the transmission give the vehicle an extended operating range and Technician B says that the final drive assembly has various gear ratios that can be selected with a gearshift lever,

The person that is correct between the two of them is Technician A and this is because the gear ratios in the transmission shows how each gear which has a different diameter, and each of the axes rotates at a different speed when they are both engaged

What is a Gear Ratio?

This refers to the ratio between the rotational speeds of two meshing gears.

Hence, we can see that Based on the fact that Technician A says that the gear ratios in the transmission give the vehicle an extended operating range and Technician B says that the final drive assembly has various gear ratios that can be selected with a gearshift lever,

Sadie wants to sell her fan-fiction on the online platform Fanalot. Instead of selling a subscription plan to all of the stories she has written, she decides to sell readers access to each story individually. Her online research suggests that if she charges x dollars per story, she will sell – 5x+100 stories per month. Fanalot will charge Sadie 20% of the amount she charges per story. So, Sadie will earn 80% of the amount she charges per story, or 0.8x dollars, in profit. Which equation can Sadie use to estimate the price she can charge per story to earn $300 in profit each month?

Answers

The equation Sadie can use to estimate the price she can charge per story to earn $300 in profit each month is:

0.8x(5x+100) - 0.2x(5x+100) = 300

Simplifying this equation, we get:

4x^2 + 80x - 300 = 0

This is a quadratic equation that can be solved using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

Plugging in the values for a, b, and c, we get:

x = (-80 ± sqrt(80^2 - 4(4)(-300))) / 8

x = (-80 ± sqrt(73600)) / 8

x = (-80 ± 271.23) / 8

x = -43.9 or 7.9

Sadie cannot charge a negative price, so the only possible solution is:

x = 7.9

Therefore, Sadie can charge $7.90 per story to earn $300 in profit each month.
