Answer:
31m/s
Step-by-step explanation:
Using the equation of motion
v² = u² + 2gH
H is the height of fall = 49m
g is the acceleration due to gravity = 9.8m/s²
u is the initial velocity = 0m/s
v² = 0² + 2(9.8)(49)
v² = 960.4
v = √960.4
v = 30.9m/s
v ≈ 31m/s
Hence the velocity of water at the turbine is 31m/s
Answer:
343 cubic inches
Step-by-step explanation:
7 times 7 times 7 is 343
Answer:
Part A: 1.25g + 14.25 <u><</u> 55.00
Part B: 32 games
Step-by-step explanation:
A:
price per game * games played (1.25g) + money he's already spent (14.25)
must be less than or equal to his total budget (55.00)
equation: 1.25g + 14.25 <u><</u> 55.00
B:
total (55.00) - already spent (14.25) = what he can spend on games (40.75)
55.00 - 14.25 = 40.75
arcade budget (40.75) / cost per game (1.25) = 32.6
because you can't play 0.6 games, 32 games
It's 200
Step-by-step explanation:
200 = 2 × 2² × 5²
