Cause he left out the noble gases out of the periodic table for one good reason, 1: He did not know them
Answer:
1) distance walked = 210 m
2) not sure
3) avg speed = total d/ total t = 210/52 = 4 m/s approx
4) For avg vel, use the formula - displacement/time
Explanation:
im not fully sure but i studied this last year
Answer:
Explanation:
Initial angular velocity ω₀ = 151 x 2π / 60
= 15.8 rad /s
final velocity = 0
Angular deceleration α = 2.23 rad / s
ω² = ω₀² - 2 α θ
0 = 15.8² - 2 x 2.23 θ
= 55.99 rad
one revolution = 2π radian
55.99 radian = 55.99 / 2 π no of terns
= 9 approx .
Hello.
The answer is: D. wavelength
This is correct because frequency x wavelength = speed
Have a nice day
Answer:
I think its object 1
Explanation:
Because the object that has more weight has a greater momentum and the lightest object that has a less momentum will be easier to change because its lighter.
