Power = exactly (current) times (voltage)
Power = exactly (about 2 A) times (240 volts)
Power = about 480 watts
Answer:
Drawing the triangle:
H / x = tan 52.2 = 1.29
H / (4.6 - x) = tan 28.8 = .550
H = 1.29 x
H = .55 * 4.6 - .55 x
1.84 x = 2.53 combining equations
x = 1.38
4.6 - 1.38 = 3.22
Total base of triangle = 1.38 + 3.22 = 4.6
H / x = tan 52,2 = 1.29
H = 1.29 * 1.38 = 1.78 height of triangle
Check:
1.78 / 3.22 = tan 28.9
This agrees with the given value of 28.8
The answer is B. Bacteria in the plant nodules convert nitrogen from the soil into molecules the plants can use.
Answer:
final velocity = 9.6157 m/sec
Explanation:
To solve this question, we will use one of the equations of motion which is:
v^2 = u^2 + 2as
where:
v is the final velocity that we want to get
u is the initial velocity = 3.75 m/sec
a is the acceleration due to gravity = 9.8 m/sec^2
s is the distance = 4 m
Substitute with the givens in the equation to get the final velocity as follows:
v^2 = u^2 + 2as
v^2 = (3.75)^2 + 2(9.8)(4)
v^2 = 92.4625
v = 9.6157 m/sec
Hope this helps :)
