Answer:
63393.8 lbfeet/sec^2
Explanation:
Recall that the weight density of water is 62.5 lb/ft3
F = PA P = hρg = h x 62.5 x 32.2 A = 5 x dh force= integral of (hρg3 x dy) // 3 is width of plane force= integral of ( 62.5 x 32.2 x 3 x hdh) from 2 to 5 force= 62.5 x 32.2 x 3 x (5^2-2^2)/2 = 63393.8 lbfeet/sec^2
Answer:
1.24Mev
Explanation:
Using
E= hc/lambda
= (6.62x10^-19) x(3x10^8m/s)/(1x10^-12) x 1.602x10^-9
= 1.24Mev
