Q1. After being accelerated to a speed of 1.70×10^5 m/s, particle enters a uniform magnetic field of strength 1 T and travels in a circle of radius 34cm (determined by observing where it hits the screen as shown in the figure). The results of this experiment allow one to find m/q.
Find the ratio m/q for the particle.
Q2. Two ants race across a table 62.0 cm long. One travels at 4.69 cm/s and other at 3 cm/s. When the first one crosses the finish line, how far behind is second one? Reply in units of cm.
At a right angle to a magnetic field. The acceleration of gravity is 9.81 m/s2. What is strength of the magnetic field necessary to exactly balance the weight of the proton and keep it moving horizontally.

A 52.0 skateboarder wants to just make it to the upper edge of a "quarter pipe," a track that is one-quarter of a circle with a radius of 2.90. What speed does he need at the bottom.
Two balls, of masses = 60 and = 70, are suspended. The lighter ball is pulled away to a 67 angle with the vertical and released. Suppose that the positive axis is directed to the right.
For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed..

What is magnitude of the current
When people sleep, their metabolic rate is about 2.6 10-4 C/(s • kg). How many Calories does an 83 kg person metabolize though getting a good night's sleep of 9.0 hours.
If a person were to push hardly on a solid wall will the work be done? Also, why would it be exhausting to push hardly against this solid wall?
The mass m =1 kg is set up as a pendulum of length 0.6m as shown on the diagram. Initially in the position of h = 0.2m above the lowest point, and the pendulum is given initial speed of 1m/s. What is the largest mass M that might be temporarily lifte..
A toy cork gun contains a spring whose spring constant is 10.02 N/m. The spring is compressed 5.0 cm and then used to propel a 6.00 g cork. The cork, however, sticks to the spring for 1 cm beyond its unstretched length before separation occurs. The m..
