For the next two questions, suppose a man jumps forward toward a dock from a small boat that is not securely anchored. What happens to the horizontal motion of both the man and the boat if the boat has less mass than the man? Ignore the effect of the friction between the water and the boat in this case.
Explain what was observed with the horizontal motion of the man and the boat in terms of Newton's Laws of Motion.
The distance between points A and B along the open flow path is 500 ft. Calculate the total head loss between points A and B. Assume A and B are at the same elevation.
After completing the calculations below, sketch the pH curve for the titration of 25.0 mL of 0.200M solution of a weak acid, HA = (Ka = 6.0 x 10^-7), with 0.200M KOH. Indicate the pH at (a) the beginning of the titration
Create a graph of x-position, x-velocity, and x-acceleration versus time and a graph of y-position, y-velocity, and y-acceleration versus time.
A transverse electromagnetic plane wave with a frequency of 2.84 MHz travels directly away from you (- z direction). At time t = 0, your magnetic field detector measures a magnetic field of 4.57 × 10-8 Tesla pointing down (- y direction) that further..
An ion harvester is scouring deep space for isolated xenon (Xe+) ions. A xenon ion is singly ionized and has the charge of +e. If the field meter reads 0.000000202 N/C, how far away is it from the ion.
A 10 μF capacitor is charged to 15 V. It is next connected in series with an uncharged 5.00-μF capacitor. The series combination is finally connected across a 50.0-V battery, as diagrammed. Find out the new potential differences across the 5-μF an..
Determine the magnitude of the force between two point charges, Q1 = -2e located at (-3.60 cm, +4.10 cm) and Q2 = -8e located at (-0.60 cm, -8.60 cm).
An 80.7-kg jogger is heading due east at a speed of 1.950 m/s. A 53.60 kg jogger is heading 33.1° north of east at a speed of 2.89m/s. compute the magnitude (enter first) and direction of the sum of momenta of the two joggers.
If the pump outlet is blocked and the handle pushed until internal length of the pump cylinder is 21, by how much does the air temperature rise? Suppose that no heat is lost.
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
Using kinematic equations prove that if two balls are released simultaneously from a table, one with zero velocity and other with horizontal velocity, they will both reach ground at the same time.
What is minimum important in returning blood to the heart? Negative intrathoracic pressure, valves and veins, the pumping action of skeletal muscles, or the pushing of blood by arterial system.
