a cube made of wood has sides 15.20 cm in length with an uncertainty of 0.05 cm. A cylindrical hole is drilled perpendicular to the cube from one side to the other. The diameter of the hole is 2.55 cm with 0.01 cm of uncertainty. What is the final volume of the cube and its uncertainty?
An RC circuit is connected across a DC voltage source through an open switch. The switch is closed at t = 0 s. Which of the following is a correct statement regarding the circuit
Two identical coils are parallel to each other on the same axis. Find an expression for the magnetic field strength at the mid-point between the loops
A 1055-kg van, stopped at a traffic light, is hit directly in the rear by a 790-kg car traveling with a velocity of +2.40 m/s. What is the final velocity of each vehicle
Two small spheres hang in equilibrium at the bottom ends of threads, 40.0 cm long, that have their top ends tied to the same fixed point. Find the distance between the centers of the spheres
suppose you have a heat engine operating between 230 C and 100.0 c. it achieves 20.0% of the maximum possible efficiency(carnot Efficiency). what energy input will enable the engine to perform 12.0 kJ of work?
A cylinder of brass has a diameter of 3mm and a length of 100mm. What is the stress in the cylinder
A man stands on a platform that is rotating (without friction) with an angular speed of 1.8 rev/s; what is the resulting angular speed of the platform
How to find the magnetic field
Calculate the magnitude of the planes acceleration. On a level road with its brakes on, a car traveling at 93 km/hr stops within 87 m when the brakes lock and the car slides.
If a person can jump a maximum horizontal distance (by using a 45° projection angle) of 2.2 m on Earth, what would be his maximum range on the Moon, where free-fall acceleration is g/6 and g = 9.80m/s2.
Energy Budget and Habitability
A 4.25 bullet traveling horizontally with a velocity of magnitude 375 is fired into a wooden block with mass 1.10 , initially at rest on a level frictionless surface. The bullet passes by the block and emerges with its speed reduced to 110 .
