Is there supposed to be options with this or are those the options there, steeper and smaller
Sublimation is the changing of a solid directly to a gas without turning into a liquid first. Where as vaporization is the liquid turning into a gas.
Answer:
spring constant of the spring is 1820.44 N/m
Explanation:
given data
ball mass = 4 kg
speed = 16 m/s
distance = 0.75 m
to find out
spring constant of the spring
solution
we know that kinetic energy of ball = energy store in spring as compression
so we can express it as
0.5 × m × v² = 0.5 × k × x² ....................1
so put here value we get spring constant k
m × v² = k × x²
4 × 16² = k × 0.75²
solve it we get
k = 1820.44 N/m
so spring constant of the spring is 1820.44 N/m
Answer:
50 km/hr
Explanation:
150 km devided into 3 hours is 50
I think the answer may be d I'm not completely sure
