Answer:
Ω
Explanation:
Given that
d(min,0)= 4 cm
d(min,1)= 14 cm
Voltage standingwave ratio = 1.5
Zo = 50 Ω
We know that
d(min,1) - d(min,0) = λ/2
Now by putting the values
14 - 4 = λ/2
λ = 20 cm
We also know that
β=2π/λ
β=2π/0.2 = 10π rad/m
So we can say that
θr= 2β d(min,n) - (2 n + 1)π rad
θr=2×10π ×0.04 −π = -0.2 π rad
We know that
π rad = 180 °
θr= = -0.2 π rad= -36 °
We know that
Here S= 1.5
by putting the values
Ω
Answer:
work output is always less than work input - the ratio is less than 1.
Explanation:
This principle comes from the fact that a machine or system cannot produce more work than is supplied to it, because this would violate the energy conservation law (work is a type of mechanical energy).
In theoretical machines called "ideal machines" the input work is the same as the output work, but these machines are only theoretical because in real applications there is always some type of energy loss, either in heat produced by a machine or processes for its operation, for this reason the output work is always less than the input work.
Regarding the ratio work output to work input:
because work input WI is always greater than work output WO.
Use cross multiplication to answer this. Since there is 2.5 grams in 1 serving, you would set it up with grams of fat being the numerator and servings being the denominator, like this:
2.5 / 1 = x / 3.75
Then just do the algebra:
(2.5 / 1) * (3.75) = x
And the answer is:
9.375 = x
Answer:the dart goes 6m deep
Explanation:
1/2 k x1² = mgh1 (1)
1/2 k x2² = mgh2 (2)
Dividing 1 by 2 gives the relation
(x1/x2)²= h1/h2
using given
[x/ (x/2)]²=24/h2
4= 24/h2
h2=6 m
