A) What is the pressure at a depth of 5000 m in the ocean?
B) What is the fractional volume change ? V/V of seawater at this pressure?
C) What is the density of seawater at this pressure?
A charged ion has a mass of 2.5x10^-26 kg and charge 1.25x10^-19 C. Determine the radius of the path
In daily life we see many cases of people who are caught misrepresenting things and who soon after that are excused and accepted by their contemporaries. How is this different in science.
A block of mass m = 4.2 kg, moving on a frictionless surface with a Vi=2.9m/s speed makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.2 block recoils with a speed of 0.9m/s. The mass M is closest to.
In the Cavendish balance apparatus, suppose that m1=1.00 kg, m2= 20.0 kg, and the rod connecting each of the pairs of masses is 28.0cm long. find the magnitude of the net force on one of the small masses
An empty hollow metal sphere has a potential of +170 V with respect to ground (defined to be at V = 0) and has a charge of 1.1 10-9 C
One particle has a mass of 4.41 x 10-3 kg and a charge of +6.92 ?C. A second particle has a mass of 6.52 x 10-3 kg and the same charge. The two particles are initially held in place and then released.
A 7.9 kg ball that is originally 3.93 m above a spring is released from rest. How far will the spring compress when the ball lands on it
A car battery with a 12 V emf and an internal resistance of 0.035 is being charged with a current of 60 A. What is the rate Pr of energy dissipation inside the battery
A worker pushes horizontally on a large crate with a force of 185 N, and the crate is moved 4.4 m. How much work was done
An electron drops from the L shell to the K shell and gives off a K X-ray with a wavelength of 0.2510 nm. What is the atomic number of this atom
A volleyball is spiked so that its incoming velocity of +4.79 m/s is changed to an outgoing velocity of -12.0 m/s. find the magnitude of the impulse that the player applies to the ball
A simple pendulum is made from a string that is 0.65m inlength with a mass of 0.2 kg attached to the free end. The mass is pulled to one side through a small angle and released fromrest. What s the angular frequency and period of the pendulum? if t..
