Answer:
yes
Explanation:
Because they have logic duh!!! ;D
For the velocity graph: start at 0s and 4m/s and draw a straight line to 2s and 2 m/s. Then draw a straight horizontal line to 4s and 2m/s
For the acceleration graph: start with a horizontal line from 0s and 2m/s/s to 2s and 2m/s/s. The draw another line from 2 s and 0m/s/s to 4 s and 0m/s/s
Answer:B
Explanation:
Given
mass of sledge=82 kg
Force on sledge=160 N
degree
force has two component sin and cos
Normal reaction
Atomic mass (z) - atomic number / # of protons (n) = # of neutrons:
151-54=97
You can easily tell what element X is. With an atomic number of 54, the element is the noble gas Xenon (Xe).
