In an effort to protect a rhino, volunteers are following its steps with air monitoring and ground cameras. the rhino starts on day 1 from ground camera a and walks for 1.5 km west along a straight line as seen from the air. the rhino then moves 0.7 km on a straight line in a direction of 15° east of north toward ground camera b. in this location the rhino may find water and food, therefore the animal stays for the night. on the second day, the rhino moves 2.5 km directly south as recorded from the air by the volunteers. in these two days of tracking how far and in which direction does the rhino travel from camera a?

What is the kinetic energy of a baseball moving at a speed of 40 m/s if the baseball has mass of 0.15 kg?

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.

The dipole moment of the water molecule (h2o) is 6.17x10^-30 c.m. consider a water molecule located at the origin whose dipole moment p points in the +x-direction. a chlorine ion ( of charge-1.60x10^-19c , is located at x=3.00x10^-9m . assume that is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis can be used. a) find the magnitude of the electric force that the water molecule exerts on the chlorine ion. b) what is the direction of the electric force. -x-direction or +x-direction c) is this force attractive or repulsive?
