- Weight of the ozone layer 1 Incredibly, the ozone layer in the upper atmosphere that protects us from the ultraviolet rays of the Sun varies somewhat but, on the average, would be less than one centimeter thick if it were brought down to sea level. Given that the density of ozone at sea level would be about 2.0 grams per litre, what is the total amount of ozone (in Tonnes) in the upper atmosphere when its sea-level thickness is 0.22 cm? Take the radius of the Earth to be 6400 km. (The volume of a thin skin around an object is the surface area of the object times the skin thickness.) Give your answer in gigatonnes, and do not specify units in the answer box. Answer Show feedback Updated 7 minutes ago 3Help me to solve this problem I don’t understand it%2: QUESTION 2 A room is filled with an ideal gas at a temperature T= 407 K and pressure p = 2 atmospheres (abbreviated atm). The dimensions of the room are 3 mx 2 mx 5 m. Use the ideal gas law pV = NkT to calculate the number of molecules in the room. The constant k is Boltzmann's constant - if you do not know its value then look it up on Google or in the Constants menu item on Blackboard. Be careful to choose a value with the right set of units for this problem. Note that 1 atm = 1.013 x 10° Pa, where the Sl unit for pressure is pascal (Pa), a Nm2 (Newton, not number). Note that if you use SI units consistently, then your answer will be in terms of number of molecules, which is dimensionless. Submit your numerical answer in exponential form as described in the worksheet instructions, QUESTION 3 If the molecules in a gas are nitrogen (N2) molecules, calculate their root mean squared (RMS) speed, y(), in m/s when T= 300 K. Do not include units in your answer. Hint: You will need to…

The tension force is inclined at an angle e = 23.0° above the horizontal and the friction force has magnitude f, = 13.5 N. The box is pulled a distance d = 1.65 m. Determine the work done on the box by the tension force, the normal force, and the kinetic friction force. We'll use W, Wa and W, to represent the magnitudes of the tension, normal, and friction forces, respectively. W = W. = Question 5.1b: The figure below shows a 1.70 x 10*-N car rolling down a ramp inclined at an angle of 0 = 34.5° above the horizon. The car rolls a distance of 14.0 m.Nuclear scientists have determined that a fourth state of matter exists: plasma. The state of plasma is reached when matter acquires a temperature so high that some of the molecules and atoms are broken down into ions and electrons. Stellar and interstellar matter mostly occur as forms of plasma. On Earth, plasma exists in the ionosphere, in flames, and in chemical and nuclear explosions. Matter in a controlled thermonuclear reactor also exists in a plasma state. Plasma is most like a gas. However, it differs from un-ionized gas in that it is a good conductor of electricity and heat. Scientists hope to understand the occurrence of plasma in nature and to harness it as an inexpensive energy source. 26. Based on the passage, how can the cost of developing thermonuclear power with plasma be defended? A. It is applicable to all technologies. B. A plasma power source can be used without special equipment. C. It can provide an inexpensive power source. bagga bniy D.

There is no one around to help, so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley You pull up on the rope to lift the box. (Figure 1) Part A Once you have pulled hard enough to start the box moving upward, what is the magnitude F of the upward force you must apply to the rope to start raising the box with constant velocity? Use g for the magnitude of the acceleration due to gravity and neglect friction forces. Express the magnitude of the force in terms of m, the mass of the box.
