The answer is: the building codes, which are a set of rules that regulate the conditions that a building must meet. Those requirements are very important to guarantee safety of both the people who are building it and the people who are going to work or live inside of the building in the future
Answer:
30 m/s
Explanation:
A boat moves initially at 10 m/s
The boat accelerates at 2 m/s^2 for 10 seconds
We are required to calculate the final velocity (v)
Therefore the velocity of the boat can be calculated as follows
v = u + at
u= 10 m/s
a= 2 m/s^2
t= 10 seconds
v= 10 + 2(10)
v= 10 + 20
= 30 m/s
Hence the velocity of the boat after 10 seconds is 30 m/s
C. Elastic collision. A perfect elastic collision is on that doesn't result in any k.e loss during the collision.
Answer: A, C, E
Explanation:
Gamma rays, Microwaves, and Radio waves
Explanation:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength.
