Which of the following is the formula for work?

47% Answer Correctly

\(W = \vec{F}\vec{d}\)

\(W = {\vec{F} \over \vec{d} }\)

\(W = {F}{d}\)

\(W = {{F}\over{d}}\)
Solution

Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement:  \(W = \vec{F}\vec{d}\)

Which of the following would you find in the side view mirror of a car?

57% Answer Correctly

concave lens

concave mirror

convex mirror

convex lens
Solution

A concave (or converging) mirror bulges inward and focuses reflected light on the mirror's focal point where the mirror's angles of incidence converge. In contrast, a convex (or diverging) mirror bulges outward and diffuses the light waves that strike it. A common use of a concave mirror is in a reflecting telescope, a common use of a convex mirror is in the side view mirror of a car.

5

Which of the following is not true about simple magnets?

62% Answer Correctly

opposite poles attract each other

all of these are untrue

opposite poles repel each other

same poles repel each other
Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.
