Answer: Noah's speed is 20km/hr
Explanation:
Given;
Final Distance between them at 5pm =320km
Time of travel = 5pm - 1pm = 4 hours
Let x represent Noah's speed
The Ryan's speed = 3x
Total distance between them in 4hours given that they are traveling at opposite directions is.
Distance = speed × time
(x + 3x) × 4hours = 320km
4x × 4 hours = 320km
x = 320km/(4×4hours)
x = 20km/hr
Noah's speed is 20km/hr
Helium, Neon, and Xenon are all part of the same column on the Periodic Table. Such a column is referred to as a Group, because they have the same number of valence electrons in their outermost shell. Hope this helps!
Answer:
The player's speed is 1.93 m/s.
Explanation:
Given that,
Mass of football = 71.5 kg
Speed = 2.00 m/s
Mass of football = 0.470 Kg
Speed = 12.5 m/s
We need to calculate the initial momentum of the football player and ball
Put the value into the formula
We need to calculate the final momentum of the system
Put the value into the formula
We need to calculate the relative to the ground
Using conservation of momentum
Put the value into the formula
Hence, The player's speed is 1.93 m/s.

In the digital recording process, the wave is measured or sampled, and the information is converted to mathematical units or quantized. ... The more often the wave is sampled (its sampling rate), the more fully the wave is reproduced. sampling rate. Number of digital samples taken per second.
