1 answer:

6 0

When making a u-turn, you must be sure that there are no approaching cars within 200 feet. Making a U-turn means turning the car to 180 degrees on a street going to the opposite direction. To do it legally, there should be no prohibiting sign, you are in the far lane and there are no car within 200 feet from you.

Which type of circuit has two or more branches for the current to flow through?

stiks02 [169]

Hello,

The answer is A. Parallel circuit.

Unlike a series circuit, these circuits allow currents to flow through multiple branches. An open circuit is an electrical current that is not valid, therefore there will be no current flow. A combination circuit, I believe, <span>is a </span>circuit<span> that is a blend of series paths and parallel paths.

Two satellites are in circular orbits around Earth. Satellite A has speed vA. Satellite B has an orbital radius nine times that

zaharov [31]

Answer:

option B

Explanation:

given,

Satellite B has an orbital radius nine times that of satellite A.

R' = 9 R

now, orbital velocity of the satellite A

$v_a =\sqrt{\dfrac{GM}{R}}$ ........(1)

now, orbital velocity of satellite B

$v_b=\sqrt{\dfrac{GM}{R'}}$

$v_b=\sqrt{\dfrac{GM}{9R}}$

$v_b=\dfrac{1}{3}\sqrt{\dfrac{GM}{R}}$

from equation 1

$v_b=\dfrac{v_a}{3}$

hence, the correct answer is option B

Transverse waves travel with a speed of 20.0 m/s on a string under a tension of 6.00 N. What tension is required for a wave spee

marta [7]

Based on the sped of the waves and the tension as well as the needed wave speed, the required tension is 13.5 N.

<h3>What is the required tension?</h3>

Given the initial tension and speed, the tension that is required can be found by the formula:

= Initial tension x (Required speed / Initial speed)²

Solving gives:

= 6 x (30 / 20)²

= 6 x 9/4

= 13.5 N

In conclusion, the tension required is 13.5N.
