A flat coil enclosing an area of 0.08 m2 is rotating at 57 rev/s, with its axis of rotation perpendicular to a 0.20 T magnetic field.
(a) If there are 998 turns on the coil, what is the maximum voltage induced in the coil?
V
A 211-? and a 221-? resistor are connected in series across an unspecified power supply, what is the exact current (in A) through the 221-? resistor
What is clowns total displacement
A steel rod (? = 7860 kg/m3) has a length of 2.19 m. It is bolted at both ends between immobile supports. Initially there is no tension in the rod, because the rod just fits between the supports. Find the tension that develops when the rod loses 3..
An electric force of 4.0 N exists between two objects separated from each other by a distance of r. If the distance is decreased to 0.50 r, compute the magnitude of the force between the two objects.
In a performance test, each of two cars takes 9.40s to accelerate from rest to 25 m/s. Car A has a mass of 1288 kg, and car B has a mass of 1767 kg. Find the net average force that acts on (1) car A and (2) car B during the test.
