In chemistry, a valence electron is an outer shell electron that is associated with an atom and that can participate in the formation of a chemical bond only the outer shell is not closed. So, the answer to this question wold be outermost energy level.
The spring constant, k, will be equal to 18 N/m. The spring constant is defined as the force-to-displaced-length ratio.
<h3 /><h3>What is the spring constant?</h3>
Spring constant is defined as the ratio of force per unit displaced length.
Given data;
Mass of block,m=0.250 k
Amplitude,A = 0.125 m
Velocity,V=3.00 m/
Spring constant, K=?
The spring constant formula when the spring oscillates at the specified amplitude A:
Hence, the spring constant, k will be 18 N/m

Answer:
d.20760 J
Explanation:
We are given that
Mass of cart=m=100 kg
At the top,h=22 m
Amount of energy convert into heat due to friction=E=800 J
We have to find the kinetic energy at the bottom of the ramp.
Potential energy drop=mgh=
Kinetic energy at the bottom=Potential energy drop-energy lost due to friction
Kinetic energy at the bottom =(21560-800) J
Kinetic energy at the bottom=20760 J
Hence, the kinetic energy at the bottom of the ramp=20760 J
d.20760 J
Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
