1. Peter rides his bike 5 blocks north and then 10 blocks east. What is his displacement? What is his total distance traveled? 2.. In kinematics, what does the sign (positive or negative) of a vector identify? 3.. What is the primary difference between speed and velocity? 4. Suppose a caterpillar crawled from the 0 cm mark to the 20 cm mark and back in 10 seconds. a.) What would the caterpillar’s speed be? b.) What would the caterpillar's velocity be? 5. If an object has positive acceleration and is traveling in a negative direction, it is

The summit of chimborazo, in ecuador, which is at a distance of about 6,384 km from the earth's center. the bottom of the mariana trench, in the western pacific ocean, which is nearly 6,370 km from the center of the earth. on the surface of earth on the equator line.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.

What do elements in a family tend to share. a.) similar periods b.) similar groups c.) similar atomic symbols d.) similar chemical properties and characteristics
