Answer:60mph means it runs every minute.
Explanation: because it makes sense.
I think it’s electromagnetic induction
Answer:
Both spheres hit the ground at the same time, but sphere A lands twice as far as sphere B from the base of the tower.
Explanation:
Since both spheres are released from the same height, therefore, the displacement is the same to mean they hit the ground at the same time. Considering that the speed of ball A is double the speed of ball B, it implies that A will land twice as far as B from the base of the tower.
Answer:
3.4093
Explanation:
NPSHa = hatm + hel + hf +hva
the elevation head is the hel
friction loss head is hf
NPSHa is the head of vapour pressure of fluid
atmospheric pressure head is hatm
log₁₀P* =
log₁₀Pv =
= 4.07827 - 1343.943/333.377
=4.07827 - 4.0313009
= 0.0469691
we take the log
p* = 1.114218
we convert this value to get 111421.8
hvap = 111421.8 * 1/776.14 * 1/9.81
= 14.63
hatm = 1.1 *101325/1 * 1/9.81 *1/776.14
=14.64
hf = 7000/1 * 1/776.14 * 1/9.81
= 0.9193
NPSHa = 2.5
hel = 0.9193 + 2.5 + 14.63 - 14.64
hel = 3.4093
