C. Democritus was a Greek philosopher who defined the concept of atoms and is the only one of the answer choices who lived during that time period.
Answer:
3 m/s
Explanation:
Given:
a = 2 m/s²
Δx = 10 m
v = 7 m/s
Find: v₀
v² = v₀² + 2a (x − x₀)
(7 m/s)² = v₀² + 2 (2 m/s²) (10 m)
v₀ = 3 m/s
Answer:
Normal Force, Applied force, Gravitational Force, Spring Force
Explanation:
Normal Force so that he does not fall into trampoline, spring because the trampoline spring down when the force goes down, then up putting force upwards, gravitation because of gravity, and applied because of jumping
Answer:
0.0195 m
Explanation:
= density of hockey puck = 9.45 gcm⁻³ = 9450 kgm³
= diameter of hockey puck = 13 cm = 0.13 m
= height of hockey puck = 2.8 cm = 0.028 m
= density of mercury = 13.6 gcm⁻³ = 13600 kgm³
= depth of puck below surface of mercury
According to Archimedes principle, the weight of puck is balanced by the weight of mercury displaced by puck
Weight of mercury displaced = Weight of puck
