Answer:
2500m
Explanation:
given,
initial velocity(u) = 5m/s
final velocity (v) = 0 m/s ( as he/she stopped riding after 1000 secs)
time = 1000 secs
distance(s)=?
now,
s=( u+v ) ×t /2
=(5+0)×1000/2
=2500 m
hence, he /she travels 2500m far
The edge length of the unit cell at the given atomic mass and density of the molybdenum is 314.2 pm.
<h3>Volume of molybdenum</h3>
V = (zm/ρN)
where;
- z is 2 for cubic unit cell
- m is mass of the molybdenum
- ρ is density of the molybdenum
V = (2 x 95.96) / (10.28 x 6.02 x 10²³)
V = 3.10 x 10⁻²³ cm³
<h3>Edge length of the unit cell</h3>
a³ = V
a = (V)^¹/₃
a = ( 3.10 x 10⁻²³)^¹/₃
a = 3.142 x 10⁻⁸ cm
a = 3.142 x 10⁻¹⁰ m
a = 314.2 x 10⁻¹² m
a = 314.2 pm
Thus, the edge length of the unit cell at the given atomic mass and density of the molybdenum is 314.2 pm.

Answer: SI Unit is meters per second(m/s)
Explanation:
The three units of speed are:
1. meters per second(m/s)
2. kilometers per hour(km/hr)
3. miles per hour(mph)
SI Unit is meters per second(m/s)
Distance of fall = (1/2) · (acceleration of gravity) · (time)²
= (1/2) · (1.63 m/s²) · (9 sec)²
= (0.815 m/s²) · (81 sec²)
= 66 meters .
On Earth ... IF there were no air ... the feather would fall
397 meters in the same amount of time !
