Answer:19ohms
Explanation:
equivalent resistance=5+2+12
equivalent resistance=19ohms
Average velocity is a vector unit (i.e. includes magnitude <em>and </em>direction) calculated by working out distance ÷ time:
80 metres ÷ 20 seconds = 4 metres/seconds (m/s)
Therefore, your final answer is C. 4 m/s south.
Answer:
Because weight W = M g, the ratio of weights equals the ratio of masses.
(M_m g)/ (M_w g) = [ (p^2 Man )/ (2 K_man)] / [ (p^2 Woman )/ (2 K_woman)
but p's are equal, so
K_m/K_m = (M_w g)/(M_m g) = W_woman / W_man = 450/680 = 0.662Explanation:
When the canoe leaked, the boat
sank because it has a leak. The boat must have a strong base at its bottom to
enable itself to float. If this is damaged, the water can now enter due to the
hole thereby increasing the velocity of water coming in.
