A student is moving a length of wire in a magnetic field. The wire is connected to an ammeter. In her investigation, she finds that some types of motion do not generate an electric current. Which of these motions results in no electric current?
A) moving the wire at a 45-degree angle to the magnetic field
B) moving the wire at 30-degree angle to the magnetic field
C) moving the wire parallel to the magnetic field
D) moving the wire perpendicular to the magnetic field
C) moving the wire parallel to the magnetic field
Question 1206190: What are the solutions to (x + 6)^2 = 36? A. 6 and 0 B. -12 and 0 C. 6 and 36 D. 42 and 30
To find the solutions to the equation (x + 6)^2 = 36, we first take the square root of both sides to get rid of the square:
√((x + 6)^2) = √36
x + 6 = ±6
Now, solve for x:
x + 6 = 6 or x + 6 = -6
x = 6 - 6 or x = -6 - 6
x = 0 or x = -12
Therefore, the solutions to the equation are:
B) -12 and 0
