I want to examine the surface of a planet that is covered by a thick atmosphere (which includes oxygen and contains a very thick layer of water clouds that never clears). What wavelength of electromagnetic radiation would I be smartest to use: radar waves.
Radars send out electromagnetic waves much like wireless computer networks and cell phones. The signals are despatched out as short pulses which can be reflected by objects of their route, in part reflecting returned to the radar.
The radio waves travel outward from the antenna at the velocity of light (186,000 miles or three hundred,000 km in keeping with the second) and keep going until they hit something.
Then some of them bounce back in the direction of the antenna in a beam of contemplated radio waves also visiting at the speed of light. the speed of the waves is crucially vital.

I think it's B: b.
Use the number that lines up with the bottom part of the blue line on the left of the thermometer
Explanation:
The liquid in the thermometer makes a "U" crescent and you have to use the bottom of the "U" touches the the lines on the side.
It’s important for a scientist to be open-minded because they need to be able to understand or creative anything that was never thought about. It’s also important for a scientist to be skeptical because some ideas or products that they hear about can have false factors. I hope this helped!
Answer:
Angle θ ≅ 21.5°
Explanation:
Given:
speed Vi= 60 m/s, Range R= 250 m, g=9.81 m/s²
To find:
Angle θ = ?
Sol: we know that Rang R = Vi² sin 2θ / g
⇒ Sin 2θ = g×R / Vi²
Sin 2θ = (9.81 m/s² × 250 m) / ( 60 m/s)²
Sin 2θ = 0.68125
2θ = Sin ⁻¹ (0.68125)
2θ = 42.9413
θ = 42.9413 / 2
θ = 21.4706 ≅ 21.5°
Oceanic crust is much denser than continental crust. This is why at convergent boundaries where oceanic and continental plates meet, the oceanic plate subducts into the upper mantle. This is also why continental plates tend to rise above oceanic plates. The reasons for this include different organic composition as well as pressure (due to gravity pulling upon the air and water).
