What is the buoyant force on the beach ball in air? the thickness of the plastic is about 2.00 mm—negligible compared with the radius of the ball. enter a positive value if the force is upward and enter a negative value if the force is downward.

it was hot sunny

explanation:

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

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

magnets not strong enough
