Answer : 18.22 meters
Explanation:
1 yard. = 0.9144 meters
85.4 yards = 78.08976 meters
1 minute = 60 seconds
5 minutes = 300 seconds
Speed of Anisa = distance / time
Speed of Anisa = 78.08976 meters / 300 seconds
Speed of Anisa = 0.26029 meters / second.
Distance travelled in 70 seconds = speed * 70
Distance travelled in 70 seconds = 0.26029 * 70 = 18.22 meters

Answer:
Wave height is the vertical distance between the crest (peak) and the trough of a wave. Some other definitions: Still-Water Line is the level of the lake surface if it were perfectly calm and flat. Crest is the highest point on the wave above the still-water line.
Explanation:
The density of the metal can be determined through the formula [n*MW]/ Na*[a^3] . substituting, we get,
<span>d = [n*MW]/ Na*[a^3]
</span><span>d = [4 atoms*42.3 g/mol]/ [6.022 x 1023atoms/mol* (sqrt 8 *1.20x10-10)^3]
</span>d = 0.719 g/cm3
Answer:
- 1 m/s, 20 m
Explanation:
u = 9 m/s, a = - 2 m/s^2, t = 5 sec
Let s be the displacement and v be the velocity after 5 seconds
Use first equation of motion.
v = u + a t
v = 9 - 2 x 5 = 9 - 10 = - 1 m/s
Use second equation of motion
s = u t + 1/2 a t^2
s = 9 x 5 - 1/2 x 2 x 5 x 5
s = 45 - 25 = 20 m
