The palm of sheilas hand has an area of 0.0017 m2. If the atmospheric pressure on the palm is 100,000 Pa, what force is being exerted on Sheila's palm by the atmospher?

170 N

Explanation:

F=pressure(pa) ÷ area(m^2)

=100.000 ÷ 0,0017

=170 N

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
