Aclosed loop conductor that forms a circle with a radius of is located in a uniform but changing magnetic field. if the maximum emf induced in the loop is what is the maximum rate at which the magnetic field strength is changing if the magnetic field is oriented perpendicular to the plane in which the loop lies?

you would expect a sound wave to speed up. - b)

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
