The titanic was found in 1985 lying on the bottom of the north ocean.The pressure that the titanic felt at that depth was 400 times atmospheric pressure. what was the depth?
A 300-g mass at the end of an ideal spring vibrates up and down in such a way that it is 2.0 cm above the tabletop at its lowest point and 16 cm above at its highest point. find the speed and acceleration of the mass when it is 12 cm above the tabl..
A painter (m=70 kg) is standing a distance of 0.6 m from the top of a ladder (mass 40 kg and length 2.5 m). Find the conditions for static equilibrium of the ladder with the painter on top
A person can jump a horizontal distance of 2.80m on Earth. How far could the person jump on the moon, where the free-fall acceleration is g/6 and g=9.81 m/s2?
An object is placed 12.0 cm in front of a converging lens of focal length 5cm. A concave mirror with radius of curvature 20.00 cm is located 30.00 cm in back of the lens. (Refer to attached picture)
In a hydraulic system, the larger piston to be used to lift a 1670kg car has a diameter of 24.2cm, If instead compressed air at 115 psi of pressure is used, what is the largest mass car (in kg) that the system can lift
a 12.0 kg mass lies at x=-80.0 cm. A 21.0 kg mass is at x= 70.0 cm. The 12.0 kg mass is not moved to a different point on the x-axis. There is not a zero net force on the 10.0 kg mass. What is the new location of the 12.0 kg mass
A 0.760 m long brass pendulum experiences a 21.0°C temperature increase. What is the change in the period
An astronaut on the Mars attaches a small brass ball to a 1.00- length of string and makes a simple pendulum. She times 13 complete swings in a time of 35.4 seconds. From this measurement she calculates the acceleration due to gravity on the Mars.
questiona 20 kg floodlight in a park is supported at an end of a horizontal bean of negligible mass that is hinged to a
An object is moving with a constant velocity V1=2i+4j for 5 seconds. It then moves with a constant velocity of V2=-3i=2j for 10 seconds, determine the final velocity vector
Regarding the Earth and a cloud layer 750 m above the Earth as the "plates" of a capacitor, calculate the capacitance. Assume the cloud layer has an area of 1 km2 and that the air between cloud and ground is pure and dry.
An airplane pilot fell 355 m after jumping from an aircraft without his parachute opening. He landed in a snowbank, creating a crater 1.3 m deep, estimate the work done on him by air resistance as he fell
