A circular loop, of radius 15 cm and negligible resistance, is sitting in a perpendicular magnetic field of 0.1 T. If the magnetic field strength changes to a value of 0.5 T in 0.5 s, calculate the induced current in the loop if it is in series with a 20 ohm resistor.

It can take some of those large , industrial vehicles up to feet to stop when traveling only 60 mph, and therefore , you shoukd be mindful to not be jn the traffic right in front of them a. 100 feet b. 200 feet c. 335 feet d. 425 feet

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.
