1. You normally drive on the freeway between Lopez, Quezon and San Pablo, Laguna at an
average speed of 105 km/hr, and the trip takes 2 hours and 20 minutes. On a Friday
afternoon, however, heavy traffic slows you down and you drive the same distance at an
average speed of only 70 km/hr. How much longer does the trip take?
1. Compute for the amount of charge (q) of a 15 V battery with -45 J potential energy
2. A metal sphere has 5x10^-9C static charge. Compute the voltage if the radius is equal to 0.05m. (k=8.99 x 10^9 N.m^2/C^2
3. Find the Total capacitance of the three given capacitors in series connection, given their
individual capacitances, 4.0 μF, 15.0 μF.
4. Find the net capacitance of the three given capacitors connected in parallel, given their individual capacitances, 2.0 μF, 5.0, μF, 8.0 μF.
5. A parallel plate capacitor was placed 0.002 m apart. Compute for the capacitance if the area each plate is equal to 0.025 m^2. (ε0 = 8.85x10^-12 F/m)
In a charming 19th-century hotel, an old-style elevator is connected to a counterweight by a cable that passes over a rotating disk 1.87m
1.87m in diameter. The elevator is raised and lowered by turning the disk, and the cable does not slip on the rim of the disk but turns with it. Through how many revolutions has the disk turned when it has raised the elevator 3.36m
3.36m between floors?

The resistance 𝑅𝜃 of a particular resistance thermometer at a Celsius temperature 𝜃 as measured by a constant-volume gas thermometer is given by
𝑅𝜃 = 50.00 + 0.1700𝜃 + 3.00 × 10−4𝜃2.
Calculate the temperature as measured on the scale of the resistance thermometer which corresponds to a temperature of 60°𝐶 on the gas thermometer.
In a beauty parlor, a customer sits halfway between two plane mirrors seperately by a distance of 2 m . Each mirror forms a series of images as a result of successive reflections from each mirror. The image formed by one mirror will be the object for the other mirror. Find the distances of the first and second images of the customer formed by each mirror.
A proton moving horizontally at 3.5×10⁴ m/s enters a uniform magnetic field of 0.075 T directed upward at 30° with the horizontal. Find the magnitude of the magnetic force acting on the proton
