Physics. PH2530 Exercise1.1 Gus Perez 1.-The turning radius of a car is 36 ft. What will be the distance in meters? We got 1ft = 0.3048 m. So we solve it like, Distance = 36 ft. x (0.3048 m. / 1 ft.) = 10.9728 m. is the answer. 2. What is the sum of 1370 cm, 1575 mm, and 8.63 m in meters? (Hint: Refer to section 1.9 in the textbook.). We convert everything to meters. We know that 1m = 100 cm and 1cm = 10 mm. so we got, 1370 cm = 13.7 m and 1575mm = 1.575 m, so we add up the 3 values; Distance =

Figure 2: Stress- strain graph The stress strain relation dependent on time and time-depending behavior of materials is known as visco-elasticity. This term derived in two expressions: Viscosity and Elasticity, Elasticity is about solid whereas Viscosity resistance to flow in fluids. Therefore, this type of material is a combination of fluid and solid properties which presents a following relation

Purpose: The purpose of this lab was to find the origin of the basalt to make Adze C7727. Stone cutting tools, called adzes, were used by many ancient Pacific Islanders. Their remnants are still being found today. Adzes are composed of a hard, black volcanic rock called basalt. Basalt is the most common type of volcanic rock in the Pacific. Although, there was basalt found in several locations in Polynesia, including the Tuamotu Islands, where there was an absence of volcanic activity to create

[6370/ (6370+100)] ^2 = 0.969 That would make it 9.51 m/s^2 6370 km is the radius of the earth. For questions 2 and 3, please consult the textbook and additional research materials on Newton’s Second Law of Motion. Pay particular attention to mass, gravity, acceleration and how they inter-relate. 2. How does air resistance alter the way we perceive falling objects? As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object

necessary in order to observe the reaction and calculate more. Then the water was now filtered in the paper filter, this filter would later be dried in the sunlight and weighed to measure the mass of the product. After the filtering was complete, the percent yield could be calculated, as well as the actual mass of the precipitate. Data: |Initial: CaCl2*2H20 (g) |1.0 g | |Initial: CaCl2*2H20

is mass, v is velocity and r is radius. Procedure: Part 1: Set up apparatus, which consists of a rotor mechanism containing a mass m attached to a spring. Tape on a piece of cardboard vertically onto one end of the rotor to trigger the photogate timer. Start the rotor and gradually increase speed until the metal pointer just flips up. Record the time (up). And then gradually decrease until the metal pointer just flips down. Record the time (down). Calculate the force on the rotating mass m.

It may be hard to believe but everything in the world in is motion. Even the most still objects have atoms vibrating inside of them with energy. Energy is never destroyed, just transferred to another object. For instance when shooting a basketball you are holding the ball above your head with two hands. One to hold the ball and the other to apply force, which is an example of kinetic energy. When shooting you are jumping to build up momentum for your shot, which is an example of gravitational energy
