Name Name Kevin Jara FRIDAY Total Points: 5x2 = 10 1. What is centripetal force? A body of mass 2kg moving in a circular path with a uniform speed 45m/s. If the radius of the circle is 5m, calculate the centripetal force acting on the body. 2. What do you understand by escape velocity? Calculate the escape velocity of the earth if its radius is 6370km and g=9.81m/s“. fine hont What is its unit? Convert 5cal to joules
4. Convert: a. 50°C to OF; b. 25°Fto OC, C. 100°C to K, d. 40K to °C etc. 5. How much heat is required to increase the temperature of 40g water from 25°C to 100°C? Specific heat of water is 1 cal/g°C.
If the escape velocity of the Earth is approximately 12 km/s. What is the escape velocity for a planet whose radius is 4 times, and whose mass is 100 times that of Earth? a. 1.2 km/s b. 12 km/s c. 60 km/s d. 300 km/s e. 600 km/s
Learning Goal: To understand specific heat and heat of transformation and how they are related to temperature versus time graphs Energy can be added to a system either by doing work w an it or by adding heat tot Energy transfer by work equires a force to act through some distance Energy ansfer in the form of heat occurs between objects that are different temperatures with onergy spontaneously aveling from the higher temperature object to the lower mperature one. When...
