R = ρl/A
From the equation above R = Resistance, l = length, A = Cross Sectional Area of wire.
From the equation, it can be seen that R would increase if the wire's area is reduced.
If the area of the wire is reduced, means the same thing as:
<span>A. decreasing the wire’s thickness</span>
<h3><u>Answer;</u></h3>
A. Congress
<h3><u>Explanation;</u></h3>
- <em><u>Article II, Section 1 of the Constitution set up the office of President. It states that the executive power shall be vested in a President of the United States.</u></em>
- The Constitution explains the duties and responsibilities of the President. The President is responsible for the executive branch. The President's main duty is to see that laws are carried out.
- <em><u>The President must take action to solve problems in areas such as civil right issues, transportation needs and safety concerns, with the approval of Congress</u></em>.
Answer:
Explanation:
a ) For the ray going into syrup , angle of incidence ( i ) is 29.4 and angle of refraction ( r ) is 18.84
Refractive index of syrup = Sin i / Sin r
= Sin 29.4 / Sin 18.84
= 1.51 .
b ) The wavelength of a light is reduced in a medium by the factor of refractive index so
wavelength in the medium
= Wavelength in air / refractive index of the solution
= 632.8 / 1.51
= 419.07 nm .
The frequency remains unchanged . The frequency in the medium will be same as that in air or vacuum.
Frequency in air = Velocity of light in air / wavelength in light
= 3 x 10⁸ / 632.8 x 10⁻⁹
= 4.74 x 10¹⁴ Hz.
Frequency in the medium is same as that in air.
Velocity in the medium
V = velocity in air / refractive index
= 3 x 10⁸ / 1.51
= 1.98 x 10⁸ m /s
Answer:
a billion (1,000,000,000) gremlins
Explanation:
since 1 milliwatt is 0.001 watt you'd need 1,000 gremlins to produce 24 watts
since 1 megawatt is 1000 watts you'd need 1,000*1,000 = 1,000,000 gremlins to produce 24 megawatts
to produce 24,000 megawatts you'd need to multiply that for another 1,000
so 1000*1000*1000 = 1,000,000,000
