Answer:
the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
Explanation:
A microscope uses a mirror to reflect light to the specimen under the microscope. ... An astronomical reflecting telescope uses a large parabolic mirror to gather dim light from distant stars. A plane mirror is used to reflect the image to the eyepiece.
I think its B or D, most likely D.
Answer:
Explanation:
The devices are connected in parallel, the same voltage will flow through them
1) I, current in the 1800 W toaster
P, power = I V
where p = 1800 W
1800 /120 = I
I drawn by the toaster = 15 A
2) I, current drawn by the 1400 W frying pan = 1400 / 120 = 11.667 A
3) I, current drawn by 75 W = 75 / 120 = 0.625 A
B) Total current drawn by the circuit = 15 A + 11.667 A + 0.625 A = 27.292 A which is greater than 15-A hence the combination will blow the fuse
Answer:
Energy resources can be measured. They will include the fossil fuels, geothermal and hydroelectric potential, and increasingly the renewable resources. When the US list is compared to the World it is considered energy Rich. When Japan's list is compared to the world standard it considered energy poor.
A changing technology like nuclear fusion could substantially change the assessment.
Japan does not have any substantial, oil, coal, gas, deposits, while the US does.
