A boat moves through the sea. There is a 3000 N force to the west on the boat.
There is a 1000 N force to the south on the boat.
Determine the magnitude and direction of the resultant force on the boat. .
Draw a vector diagram of these forces to scale on Figure 11
find the magnitude of resultant force and the direction of resultant force

​

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2

Which property is expressed in distance units? o a. period o b. wavelength o c. speed o d. frequency
