Balance means net force equals zero
Answer:
thermoset
Explanation:
A thermoset material is a polymer that is irreversibly hardened by curing. Curing is induced by heat and cannot be undone because the polymers cross link during the process, creating permanent chemical bonds.
Answer: solar winds
Explanation:
<u>A solar wind is composed of high speed charged particles (plasma) ejected from the Corona- the upper atmosphere of the Sun. </u>When the temperature of the corona crosses 2 million degrees, the rapidly moving particles are not held by the Sun's gravity and release away into the solar system.
<u>The Solar wind travels throughout the solar system and carries magnetic clouds along with it. It could be damaging to life if it could reach the surface but the planet's magnetic field shields us and redirects the material beyond it. </u>
Solar wind must have reached the planet Jupiter and Dr. Tate and Dr. Ramirez would be studying its effects.

Ok so this is simple projectile motion problem.
if we have an object falling in free fall it is subject to gravity of -9.80m/s^2
so it says it takes 6 sec to fall and we know initial velocity was zero so we know that h=vt+1/2gt^2 so we get h=0+1/2*9.80*6^2 = 176.4m
so solving for final speed we get KE=PE = 1/2mv^2=mgh = 1/2v^2=gh so
v=sqrt(2*g*h) = sqrt(2*9.8*176.4m) = 58.8m/s final speed when it hits the ground
hope this helps you! Thanks!!
