Answer:
Net force is 7N, accelerations is 3.5 m/s/s
Explanation:
Answer:
v = 4.32 10⁴ m /s
Explanation:
The speed of a particle is defined as the relationship between distance and time
v = d / t
In this case the particle goes at high speed, but the formula is the same, it has changes if you want to transform from a mobile reference system to a fixed one
v = 9.5 10⁻² / 2.2 10⁻⁶
v = 4.32 10⁴ m /s
This speed is much lower than the speed of light, so the relativistic effects are small
a boulder can change due to erosion and weathering. it can change shape and sometimes color, possibly.
Answer:
60
first choice = 1/5
second choice = 1/4
third choice = 1/3
5*4*3 = 60 the number of choices
