O2 refers to two oxygen atoms bonded together, while 2 O refers to two oxygen atoms that are not bonded to each other. They both have two oxygen atoms, but in O2, the oxygen atoms are bonded, while in 2O, the atoms are not.
F = m • a
What we know:
- Gravity: 9.8 m/s
- Force: 490 N
Equation derived:
m = F/a
m = 490/9.8
= 50 kg
Explanation:
acceleration is weight*gravity
tension is the weight In Newtons
The distance of the cliff from where you are is determined as 3,430 m.
<h3>Distance of the cliff</h3>
Apply the formula for echo.
v = 2d/t
where;
- v is speed of sound at 20 ⁰C = 343 m/s
- d is distance = ?
- t is time = 20 s
2d = vt
d = vt/2
d = (343 x 20)/2
d = 3430 m
Thus, the distance of the cliff from where you are is determined as 3,430 m.
