X - rays are considered an
oxidizing mutagenic agent. 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:
3.92 cm
Explanation:
Assuming spring cinstant of 800 N/m, we know that the potential energy is transformed to kinetic energy in spring hence
where m is the mass of the block, g is acceleration due to gravity, x is the extent of compression of the spring and k is spring constant. Making x the subject of the above formula then
Substituting 1.6 kg for m, 9.81 for g and 800 N/m for k then
Answer:
2nd one I believe because its still inertia
Explanation:
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
