Suppose you fix the strength of the pushing force that you exert independently on three objects: a wooden chair, a refrigerator, and a car. Which of the objects will accelerate the most? Which of the objects will accelerate the least? Explain.
Suppose you want the acceleration of a chair, a refrigerator, and a car to be the same when pushing on them individually. Which object requires the largest pushing force? Which one requires the smallest? Explain.
Find the electrical and gravitational forces between the proton and electron in a hydrogen atom. Which force holds it together
Describe the three parts of an argument and give two examples of arguments that have these parts. Your initial posting should be at least 200 words and should use good grammar and APA citation and reference styles.
Hakeem throws an 8.00 g ball straight down from a height of 2.0 m. The ball strikes the floor at a speed of 7.40 m/s. What was the initial speed of the ball? Assume that air resistance is negligible.
A car tire has a radius of 0.290 meter, and its center moves forward with a linear speed of v = 18 meter per second. Relative to the axle, evaluate the tangential speed of a point located 0.175 meter from the axle
Find the capacitance of a parallel plate capacitor having plates of area 1.00 m2 that are separated by 0.400 mm of Teflon
A mass is attached to a spring on a frictionless horizontal surface. The mass is pulled to stretch the spring by .1 m and then gently released. A short time later, as the mass passes during the equilibrium position, its speed is 1 m/s.
For the harmonic oscillator, find the expectation value of the potential energy for the lowest energy state
Find the total energy released in MeV in each carbon cycle (elaborated in the above problem) including the annihilation energy.
A spring with spring constant 11.9N/m hangs from the ceiling. A ball is suspended from the spring and allowed to come to rest. It is then pulled down 11.0 cm and released. The ball makes 38.0 oscillations in 19.0 seconds.
Calculate the change in potential energy of a 92.8 kg man when he takes an elevator from the first floor to 29th floor, if the distance between floors is 4.41 m.
A 7450-kg car is travelling at 24.8 m/s when the driver decides to exit the freeway by going up a ramp. What is the magnitude of the average drag force
