<span>The troposphere gets its heat from the ground, and so temperature decreases with altitude. Warm air rises and cool air sinks and so the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV.</span>
On a Fahrenheit thermometer, the gas becomes 18 degrees warmer.
X - rays are considered an
oxidizing mutagenic agent. The answer is letter A. X-rays are high energy
electrons that can cause damage when exposed under extreme conditions. The best
technology that can block it is t using a lightweight type of metal foam. It
can take in high energy collisions which also exhibits high forces. it does not
only block x-rays but also, neutron radiation and gamma rays.

Answer:
Robotic arms used aboard the ISS are now used in delicate surgeries on Earth.
Explanation:
The ISS allows users to address hardware product development gaps, advanced manufacturing, and emerging technology proliferation. Microgravity-enabled material production capabilities and advanced manufacturing facilities are demonstrating scientific and commercial merit for Earth benefit
<span>Step 1 of 3
Calculate the magnitude of the earth’s velocity.
The radius of earth orbit around the sun is .
Time taken to complete one revolution is .
Convert time from days into seconds.
The expression for magnitude of earth velocity is,
Substitute for , for .
Further solved,
Explanation | Common mistakes | Hint for next step
Time taken to complete one resolution is 365 days. Convert time from days into seconds. Radius of earth orbit around the sun is given. Velocity is circumference of orbit upon time taken in one resolution. Calculate the magnitude of earth velocity. Change unit of velocity to
