The figure below shows two circular regions R₁ and R₂ with radii r₁ = 22.5 cm and r2 = 33.0 cm. In R₁ there is a uniform magnetic field of magnitude B₁ = 52.5 mT directed into the page, and in R₂ there is a uniform magnetic field of magnitude B₂ = 75.7 mT directed out of E ds for (a) path 1, (b) path 2, and (c) path the page (ignore fringing). Both fields are decreasing at the rate of 10.0 mT/s. Calculate 3.

These aren't any of the choices

Earth's gravity pulls everything downward It pulls down each kilogram with a force of 9.8 Newtons. On a force table, a thread has a brass cylinder attached to it weighing 100 grams. If Earth's gravity pulls this weight (0.1 kg) downward with 0.98 N of force, how much weight is applied by Earth's gravity to the brass cylinder hanging on the thread?

Do fast, just answer.

A car with a mass of 1200 kg moves at 17 m/s. What force is needed to bring the car to a halt in 10 s?
