Q. A 55 kg person is riding in a hot air balloon, and a scale shows this person's weight too be 549N. the acceleration of gravity at the location of the balloon is known to be 9.79 m/s/s. determine the magnitude and direction of the vertical component of the balloon's acceleration?
A sound wave traveling at 341 m/s is emittedby foghorn of a tugboat. An echo is heard2.40 s later.How far away is the reflecting object? reply in units of m.
if oxygen molecules are more massive than the nitrogen molecules, is the rms speed of the O2 molecules greater than, less than, or euqls to rms speed of the n2 molecules.
What is water speed along the boat during the vertical cross
what happens to light of a particular frequency when it is incident upon the material that natural frequency is the same as the frequency of the light.
A certain car battery with a 12.0 V emf has an initial charge of 178 A•h. assume that the potential across the terminals stays constant until the battery is totally discharged, for how long in hours can it deliver energy at the rate of 115 W.
Extimate the thickness of a glass at a bright fringe and the Brewster's angle for light traveling from air to glass.
An 84 kg skier is being pulled by a boat with a force of 240 N causing the skier to accelerate at 1.4 m/s^2. Find out the drag force on the skier.
A 21.5 g bullet strikes a 0.650 kg block attached to a fixed horizontal spring whose spring stiffness constant is 7.30 x 10^3 N/m and sets it into vibration with an amplitude of 21.5 cm. What was the speed of bullet before impact if the bullet and bl..
110 grams of boiling water (temperature 100° C, heat capacity 4.20 J/gram/K) are poured into an aluminum pan whose mass is 1000 grams and initial temperature 24° C (the heat capacity of aluminum is 0.9 J/gram/K).
Three objects with masses, m1 = 6.0 kg, m2 = 10.0 kg, and m3 = 15.0 kg, are attached by strings over frictionless pulleys as indicated. The horizontal surface is frictionless and the system is released from rest. Using energy concepts, find out th..
