- Don't use chat gptWhen working on a PHYS 1510 weekly assignment, a student decided to get a medium double double coffee from Tim Hortons (a coffee made with two creams and two sugars). After drinking it, the student looked up the nutritional value of the drink, and was shocked to find it was listed as 230.0 kcal (230.0 nutritional calories). After drinking the coffee, they weighed 87.88 kg. To work off all the calories, the student decides to climb the stairs in their building. How many floors do they need to climb to burn off the entire drink? (do not include units) Assume all floors are 3.00 m apart from each other. Assume all nutritional energy is fully converted to potential energy. 1 kcal = 4184 JBacteria have a density that is about the same as water. Their average velocity is 10^-3 m/s. A bacterium with a radius of 1 um should have a diffusion coefficient of about 2.2x10^-13 m^2/s. (a) Find the random-walk step size (b) How long does it take for an average walk to reach 1 mm in seconds and days? Note that we are considering the diffusion away from the starting point and are calculating the distance through three dimensions. Show your work
- Carbon dioxide gas, CO2, travels at about 340 m/s at room temperature. What is the travel rate (velocity) of helium, He, at the same temperature?A light bar AD is suspended from a cable BE and supports a 30-kg block at C. The ends A and D of the bar are in contact with frictionless vertical walls. Determine the reaction at D in N. a =196 mm, b =110 mm, c =80 mm and d = 160 mmA 53−kg person drinks5.4×102g of milk, which has a caloric value of approximately 3.0 kJ/g.If only 17 percent of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? Enter your answer in scientific notation. Hint: The work done in ascending is given by mgh, where m is the mass (in kg), g is the gravitational acceleration(9.8 m/s2), and h is the height (in meters).
