Amber (n = 1.546) is a transparent brown-yellow fossil resin. An insect, trapped and preserved within the amber, appears to be 2.53 cm beneath the surface, when viewed directly from above. How far below the surface is the insect actually located?
(a) How much charge can be placed on a capacitor with air between the plates before it breaks down if the area of each plate is 6.00 cm2? (b) Find the maximum charge if bakelite is used between the plates instead of air.
A 3.00-kg object is fastened to a light spring, with the intervening cord passing over a pulley. The pulley is frictionless, and its inertia may be neglected.
After being accelerated to a speed of 1.84×105, the particle enters a uniform magnetic field of strength 1.00 and travels in a circle of radius 35.0. The results of this experiment allow one to find.
Blocks with masses of 2, 3, and 5 are lined up in a row on a frictionless table. All three are pushed forward by a 59 force applied to the 2 block. How much force does the 3.00 kg black exert on the 5 kg block.
A 21 kg block on a horizontal surface is attached to a horizontal spring of spring constant k = 2.3 kN/m, What is the kinetic energy of the block when it has moved 2.0 cm from its point of release
Two identical metallic blocks are connected by a light spring having the spring constant 100 N/m and an unstretched length of .30 m. A total charge Q is slowly placed on the system, causing the spring to stretch to an equilibrium length of .40 m. ..
A 120 g trick baseball is thrown at 51 km/h. It explodes in flight into two pieces, with a 50 g piece regular straight ahead at 86 km/h. How much energy do the pieces gain in the explosion.
A placekicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, By how much does the ball clear or fall short of clearing the crossbar
You are designing a delivery ramp for crates containing exercise equipment. Calculate the maximum force constant of the spring kmax that can be used in order to meet the design criteria
A rope applies a horizontal force of 180N to pull a crate a distance of 2m across the floor A frictional force of 60N opposes this motion.
If his arms are capable of exerting a force of 1400 on the vine, what is the maximum speed he can tolerate at the lowest point of his swing? His mass is 82, and the vine is 6.00 long.
One liter of water is 41C is used to make iced tea. How much ice at 0 C must be added to lower the temperature of the tea to 17C? The specific heat of water is 1 cal/g C and latent heat of ice is 79.7 cal/g. Reply in units of g.
