this is a true statement

Inverse square law: \frac{I_{2} }{I_{1}}= (\frac{d{2} }{d_{1}})^2
where 
I_{1} is the intensity at distance 1
I_{2} is the intensity at distance 2
d_{1} is distance 1
d_{2} is distance 2

The inverse squared law state that intensity decreases in inverse proportion to the distance squared. So if light obeyed that rule, it will decreases its intensity as the square of the distance increases.

We can conclude that the correct answer is: true.

Ballet position which feet turned out
Dmitry [639]
Although all ballet positons involve turned out feet, the simplest one is first position. Heels are touching and toes face out, as far away from each other as possible (close to 180 degrees of rotation).

If my mass is 196 lbm and I tackle one of my teammates - while decelerating from a velocity of 6.7 m/s to 0 m/s in 0.5 s, how mu
Olin [163]

Answer:

the force acting on the team mate is 1.19 kN.

Explanation:

given,

mass = 196 lbm

while tackling, the deceleration is from velocity 6.7 m/s to 0 m/s

time taken for deceleration = 0.5 sec        

F = mass × acceleration

acceleration = \dfrac{0-6.7}{0.5}              

                     = -13.4 m/s²                            

1 lbs  = 0.453 kg                      

196 lbs = 196 × 0.453  = 88.79 kg

F = 88.79 × 13.4                              

F = 1189.786 N = 1.19 kN                      

hence, the force acting on the team mate is 1.19 kN.
