Answer 2
Answer:

Final answer:

Given the current of 3 A and resistance of 15 Ohms, we can use Ohm's Law to calculate the voltage. We rearrange the formula to V = I * R, fill in the given values which results to V = 45 V. The correct answer is A. 45 V.

Explanation:

The problem involves Ohm's Law which is a foundational concept in Physics, particularly in the study of electricity. Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points, and is inversely proportional to the resistance (R). The formula that represents Ohm's Law is I = V/R.

Given the current (I = 3 Amps) and the resistance (R = 15 Ohms), we can rearrange the formula to solve for voltage (V). Thus, the formula becomes V = I * R. When the given values are substituted, we have V = 3 A * 15 Ω, which results in V = 45 V. Therefore, a voltage of 45 V will produce 3 A in a circuit with 15 ohms of resistance. The correct answer is A. 45 V.

If gravity did not affect the pain of a horizontally thrown ball the ball would

Answers


If gravity had no effect on a ball after you threw it ... and there also
were no air to slow it down ... then the ball would continue traveling
in a straight line, in whatever direction you threw it. 

That's the heart and soul of Newton's laws of motion ... any object
keeps moving at the same speed, and in a straight line in the same
direction, until a force acts on it to change its speed or direction.\

If you threw the ball horizontally, then it would keep moving in the
same direction you threw it.  But don't forget:  The Earth is not flat.
The Earth is a sphere.  So, as the ball kept going farther and farther
in the same straight line, the Earth would curve away from it, and it
would look like the ball is getting farther and farther from the ground.
 
If gravity did not affect a horizontally thrown ball, the ball would continue along its horizontal path indefinitely (assuming it is thrown in a vacuum so no other forces are acting on it).

A transverse wave on a string is modeled with the wave function y(x,t) = (0.20 cm) sin (2.00 m^-1 x - 3.00 s^-1 t + pi/16) What is the height of the string with respect to the equilibrium position at a position x = 4.00m and a time t = 10.00 s a. -0.037 cm
b. -0.037 cm
c. 0.370 cm
d. 0.370 cm

Answers

Answer:

Explanation:

y = (0.2 cm) Sin(2x - 3 t + π/16)

Put x = 4 m, t = 10 s

y = (0.2 cm) Sin (2 x 4 - 3 x 10 + π/16)

y = (0.2 cm) Sin (8 - 30 + π/16)

y = (0.2 cm) Sin (π/16 - 22)

y = (0.2 cm) Sin(-21.80375)

y = (0.2 cm) x (- 0.1863)

y = - 0.37 cm

Final answer:

The given wave function represents a transverse wave on a string. Substituting the given values into the wave function yields a height of -0.037 cm. The correct option is a. -0.037 cm.

Explanation:

The given wave function y(x,t) represents a transverse wave on a string. To find the height of the string with respect to the equilibrium position at a position x = 4.00m and a time t = 10.00s, substitute these values into the wave function. y(4.00m, 10.00s) = (0.20 cm) sin[(2.00 m-1)(4.00m) - (3.00 s-1)(10.00s) + π/16].

Calculating this expression gives the height of the string as -0.037 cm. Therefore, the correct option is a. -0.037 cm.

Opposite electric charges will repel, and like charges will attract.

Answers

As it stands now, that statement is false.

There are two ways to make the statement true:

#1).  Exchange the places of the words "Opposite" and "like".

#2).  Exchange the places of the words "repel" and "attract".

Either ONE of these changes will make the statement true.
Doing BOTH of these changes will leave it false.

Answer:

False. Opposite electric charges will attract, and like charges will repel.
