Answer = brainliest a car moves in a circular path as it turns on a corner on a horizontal road. the car moves at a constant speed. which description of the forces acting on the car is correct? a. all the forces are balanced as the car is moving at a constant speed. b. the forces are unbalanced and the resultant force acts away from the centre of the circle. c. the forces are unbalanced and the resultant force acts towards the centre of the circle. d. the forces are unbalanced and the resultant force is in the direction of travel of the car.

If the force on an object is in the negative direction, the work it does on the object must be [2 points a) negative. b) positive c) the work could be either positive or negative, depending on the direction the object moves

Follow these directions and answer the questions. 1. set up the ripple tank as in previous investigations. 2. bend the rubber tube to form a "concave mirror" and place in the ripple tank. the water level must be below the top of the hose. 3. generate a few straight pulses with the dowel and observe the reflected waves. do the waves focus (come together) upon reflection? can you locate the place where the waves meet? 4. touch the water surface where the waves converged. what happens to the reflected wave? 5. move your finger twice that distance from the hose (2f = c of c, center of the curvature) and touch the water again. does the image (the reflected wave) appear in the same location (c of c)? you may have to experiment before you find the exact location. sometimes it is hard to visualize with the ripple tank because the waves move so quickly. likewise, it is impossible to "see" light waves because they have such small wavelengths and move at the speed of light. however, both are examples of transverse waves and behave in the same way when a parallel wave fronts hit a curved surface.

The long handle on a rake is a(n) a. lever b. screw c. wedge d. inclined plane
