A man strikes one end of a thin rod with a hammer. The speed of sound in the rod is 16 times the speed of sound in air. A woman, at the other end with her ear close to the rod, hears the sound of the blow twice with a 0.16 s interval between; one sound comes through the rod and the other comes through the air alongside the rod. If the speed of sound in air is 345 m/s, what is the length of the rod? Number i Units

Student 1 applies a force of 10 N to a wooden board in order to slide it across the table to Student 2. If the 7 force of friction resisting the student's push is 4 N, what is the net force acting on the board? What is allowing the board to overcome the force of friction and slide across the table? A A constant balanced force from student 1 is causing the board to slide across the table. B An unbalanced force from student 1 is causing the board to move across the table Reverse friction allows the board to be affected by the balanced force from the table and slide D Force of friction is allowing the board to move across the table. 2:09 PM 9/7/2021 A DA 40) P Type here to search DELL 立

The Sun has a mass of 2 x 1030 kg and the distance from the Sun to Mars is 2.3 x 10¹¹ m. If Mars had no mass, there would still be a small gravitational force on an object near Mars's surface, due only to the Sun. What would be the value of g on (massless) Mars, due to the gravitational force of the Sun? Assume that Mars's radius is negligible compared to the distance between the Sun and Mars. i Hint - F2 eTextbook and Media Window Help F3 This problem is equivalent to assuming that there is a spherical surface surrounding the Sun, and finding the value of g on that surface. The radius of the surface is the same as the distance from Sun to the other body. OCT 20 80 N/kg F4 את % 5…
