Based on the list above the correct properties of solids are;
B) has a rigid shape that does not change easily
E) has particles that can wiggle but cannot move
Solids have a variety of properties that make them different from liquids and gasses. Their particles are fixed making them rigid and hard to change shape. The particles also have a low kinetic energy making it hard for the particles to vibrate. In addition to those properties, solids cannot be compressed into smaller sizes.
Explanation:
The lithosphere is composed of the crust and a portion of the upper mantle. the athenosphere is partially molten upper mantle material that behaves plasticly & can flow.
It is harder to work on the lower layers because its gets extremely hot & sometimes it can get so hot that it melts tools used to research these layers.
1) Time to get the highest point of it pathway>
Vf = Vo - g*t
Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s
=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s
2) Time to return from the highest point = time to get to the highest point = 0.543 s
Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s
Answer: 1.09 s
Acceleration=non-uniform velocity/time
=displacement/time^2
Answer:
k = 5178.8 N/m
Explanation:
As we know that spring mass system will oscillate at angular frequency given as
now we have
now the maximum acceleration of the spring block system is at its maximum compression state which is given as
here A= maximum compression of the spring
so here in order to find maximum compression of the spring we will use energy conservation as we know that initial total kinetic energy of the car will convert into spring potential energy
here we know that
v = 85 km/h
now we have
now from above equation of acceleration we have
