The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor. The current is 6 amperes when the resistance is 722 ohms. What is the current when the resistance is 768 ohms? Round your answer to two decimal places if necessary.

Answer 1

Answer:

Answer:

The current is 5.64 Ampere when resistance is 768 ohms .

Step-by-step explanation:

As given

The current (I) in an electrical conductor varies inversely as the resistance (R) of the conductor.

Thus

$I \propto (1)/(R)$

$I=(k)/(R)$

Where k is the constant of proportionality .

The current is 6 amperes when the resistance is 722 ohms.

I = 6 amperes

R = 722 ohms

Put all the values in the formula

$6=(k)/(722)$

k = 6 × 722

k = 4332

As given

when the resistance is 768 ohms .

R = 768 ohms

K = 4332

Put in the formula $I=(k)/(R)$ .

$I=(4332)/(768)$

I = 5.64 Ampere

Therefore the current is 5.64 Ampere when resistance is 768 ohms .

Answer 2

Answer: Basically, this is Ohm's Law:
V=RI where V is the tension in volts;
You have that V=722×6=4332 Volts
Using this value for V you have that:
4332=768×I
So I=5.64 A

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second. Convert this speed to miles per minute. At this speed, how many miles will Jupiter travel in 4 minutes? Do not round your answers.

Answers

Jupiter travels at 480 miles per minute and in 4 minutes, it will travel 1920 miles.

What is speed?

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.

First to convert it you need to multiply 8 miles per second by 60 seconds because there are 60 seconds in a minute:

8 miles x 60 s

1 second 1 min

The unit of seconds will cancel out so you will get 480 miles/ min

To get how far it travels in 4 min you need to multiply the speed by 4 minutes

480 miles x 4 min

1 min

The unit of minutes will cancel out to get 1920 miles

Therefore, Jupiter travels at 480 miles per minute and in 4 minutes, it will travel 1920 miles.

5. Factorise: p2 - 11p +30

Answers

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

Given

p² - 11p + 30

Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 11)

The factors are - 5 and - 6, since

- 5 × - 6 = + 30 and - 5 - 6 = - 11 , thus

p² - 11p + 30 = (p - 5)(p - 6) ← in factored form

Answer:

(p - 5)(p - 6)

Step-by-step explanation:

p^2 - 11p + 30

find what two numbers added together is -11 but multiplies together is 30, its' -5 and -6 so:

(p - 5)(p - 6)
