The operating speed of a personal computer is 200 gigahertz. This is one-third the speed of a newer model. Find the speed of the newer personal computer.

From a building which is 60 meters height, a ball was thrown horizontally with kinetics energy of 45 Joules. If the ball weighs 300 grams, compute for the ball’s kinetic energy when it touches the ground. Give your answer in Joules. (KE = 1/2mV1^2)

What is the Kinetic Energy of the car with a mass of 0.032 kg as it exits the track? KE = 1/2mv

Christian Huygens in the 1600’s invented the first clock which was small enough to fit in an ordinary room but much more accurate than the large tower clocks of his day. What was his big idea? Why does it work well on land but not at sea? (Ships would have to wait many years for an accurate on-board timepiece).

Same situation as in the previous problem this time the magnet has mass 6.22 kg, the force pulling it to the right is 64.1 N, the cord has length 1.99 m and the ceiling is 2.85 m above the floor. How far to the right of its start point will the magnet have traveled when it hits the floor after the cord is cut?

A person uses a set of spring-based analog scales to measure her weight.  He did the weighing process 10 times and get the following measurement figures in kilograms:60.1, 59.6, 59.4, 60.4, 59.9, 59.6, 60.2, 60.7, 59.4, and 59.7. To satisfy his curiosity, he then used one scale electronically calibrated to measure its assumed weight has zero error.  This scale gives a reading of 60.5 kg. Calculate the precision (precision) of a spring-based balance?

What is the magnetic field strength and direction at point A for the figure shown? Note that the current carrying wires are parallel with a separation of 6.0 cm and Point A is 2.0 cm away from the wire carrying 6A current. A • 6 A 12.0 cm 6.0 cm 20 A

The error in measuring the distance of a moving object is 3.44x10^-12m. If the mass of the object is 115lb, calculate the error in measuring speed.

A ball has a kinetic energy of 28.9J. If the ball were moving twice as fast, how much kinetic energy (in J) would it have?   Your Answer:

The dot product of two vectors is 77. What is the magnitude M if N = 7.9 and the angle between the two vectors is 41 degrees? and
