Answer:
Explanation:
Given that
axle with a mechanical advantage of 3 and
a wedge with a mechanical advantage of 4?
Mechanical Advantage( M.A.) in a simple machine is defined as the ratio of the force that performs the useful work of a machine to the force that is applied to the machine.
Mechanical Advantage of Compound Machine = Product of mechanical advantages of the simple machines that it consists of, that is the mechanical advantage of wheel and axle multiplied by the mechanical advantage of wedge.
Therefore,
M.A. wheel and axle = 3
M.A. wedge= 4
M.A. pencil sharpener= 12
The answer was that Copernicus objected to Ptolemaic system where the theory states that the universe is geocentric, where celestial bodies moves around the earth instead of the solar system model where it was patterned to Copernicus' model where science have accepted that the sun is indeed the center of our solar system and not true with Ptolemy's argument.
Answer:
inductance is 1.31 µH
capacitance is 1.658 pF
Explanation:
Given data
frequency = 87.7 MHz = 87.7 ×
Hz
capacitor = 2.50 pF = 2.50 ×
F
to find out
inductance and capacitance at 108 MHz
solution
we apply here resonant frequency that is
frequency = 1 / 2π√(LC) ..............1
here L is inductance and C is capacitor
put all the value and find L
√(L2.50 ×) = 1 / 2π ( 87.7 × )
√(L2.50 ×) = 1.81 × 
(L2.50 ×) = 3.296 × 
L = 3.296 × / 2.50 ×
L = 1.31 × 
H
so inductance is 1.31 µH
and
for 108 MHz = 108 × Hz
we find here capacitance c from equation 1
frequency = 1 / 2π√(LC)
√(LC) =1 / 2π frequency
√(1.31 × C) =1 / 2π ( 108 × )
√(1.31 × C) = 1.47 ×
(1.31 × C) = 2.178 ×
c = 2.178 × / (1.31 × )
c = 1.658 × F
so capacitance is 1.658 pF
