A child holds a butterfly net that is made of a fine mesh net attached to an aluminum rim. The rim is made of a solid pipe with diameter 4.00 mm formed into a circle with radius 15.0 cm. The child is running around on a 77°F day trying to catch butterflies. At one instant, the net is oriented so that a vector normal to the opening of the net faces due north. The child swings the net in a smooth arc so that 0.80 seconds later, the normal vector points due west. At this location, the Earth’s magnetic field has a magnitude of 49.6 μT and a direction of due north, 63° below the horizontal.T and a direction of due north, 63° below the horizontal. a) Find the average induced emf in the rim while the net is turning. b) In the instant before the net finishes its turn, as viewed from the east, the induced current is: Circle one (and show your work): Clockwise or counterclockwise or zero c) Find the average induced current in the rim while the net is turning.
tires need to be strong for a reason. Suppose the tread on a tire with a radius of 40cm has a mass of 5kg. If the tire is on a car travelling at 150mph, find the force the tread walls have to exert on the tread in order to keep it in circular motion.

As a hiker in Glacier National Park, you are looking for a way to keep the bears from getting at your supply of food. You find a campground that is near an outcropping of ice from one of the glaciers. Part of the ice outcropping forms a 47.5° slope up to a vertical cliff. You decide that this is an ideal place to hang your food supply as the cliff is too tall for a bear to reach it. You put all of your food into a burlap sack, tie an unstretchable rope to the sack, and tie another bag full of rocks to the other end of the rope to act as an anchor. You currently have 19.5 kg of food left for the rest of your trip so you put 19.5 kg of rocks in the anchor bag to balance it out. What happens when you lower the food bag over the edge and let go of the anchor bag? The weight of the bags and the rope are negligible. The ice is smooth enough to be considered frictionless. O The anchor bag is on a slope so the food bag will drop, pulling the anchor bag up. The motion of the food bag cannot be…

Billboards are large outdoor hoardings that are used by advertisers. However, their large surfaces at heights off the ground means they have to withstand strong winds during their useful life span. There is a need to model and analyze a billboard stand that must be capable of supporting a 5- meter x 2-meter billboard at a height of 4 meters above the ground. The billboard will have to withstand crosswinds with speeds up to 10 m/s. Please show calculations to acquire the correct intended results for an upvote...thanks.
A truck’s brakes can overheat and fail while descending mountain highways, leading to an extremely dangerous runaway truck. Some highways have runaway-truck ramps to safely bring out-of-control trucks to a stop. These uphill ramps are covered with a deep bed of gravel. The uphill slope and the large coefficient of rolling friction as the tires sink into the gravel bring the truck to a safe halt. A 22,000 kg truck heading down a 3.5° slope at 20 m/s (≈45 mph) suddenly has its brakes fail. Fortunately, there’s a runaway-truck ramp 600 m ahead. The ramp slopes upward at an angle of 10°, and the coefficient of rolling friction between the truck’s tires and the loose gravel is μr = 0.40. Ignore air resistance and rolling friction as the truck rolls down the highway. a. Use conservation of energy to find how far along the ramp the truck travels before stopping.b. By how much does the thermal energy of the truck and ramp…
