It is almost time for the summer Olympics. The Olympic hammer throw is a throwing event where the object is to throw a heavy met

al ball attached to a wire and handle. The name hammer throw comes from an older contest where men threw a sledge hammer. The hammer have different weights, ranging from 16 pounds down to 8 pounds. Imagine there are four hammers to throw: 16, 12, 10, and 8 pounds. You can pick any hammer to win the contest. Which would be the best choice if you want to throw the hammer the farthest you can? A) 16 pounds B) 12 pounds C) 10 pounds D) 8 pounds

A tank of gasoline (n = 1.40) is open to the air (n = 1.00). A thin film of liquid floats on the gasoline and has a refractive i
klio [65]

Answer:

1.08

Explanation:

This is the case of interference in thin films in which interference bands are formed due to constructive interference of two reflected light waves , one from upper layer and the other from lower layer . If t be the thickness and μ be the refractive index then

path difference created will be 2μ t.

For light coming from rarer to denser medium , a phase change of π occurs additionally after reflection from denser medium, here, two times, once from upper layer and then from the lower layer ,  so for constructive interference

path diff = nλ , for minimum t , n =1

path diff = λ

2μ t. =  λ

μ = λ / 2t

= 626 / 2 x 290

= 1.08

Newton's law of cooling says that the rate of cooling of an object is proportional to the difference between the temperature of
Feliz [49]

Answer:

T=T_o+C'e^{-kt}

Explanation:

Newton's law of cooling

Rate of cooling

\dfrac{dT}{dt}\alpha(T-T_o)

Where To is the surrounding temperature

T is object temperature at any time t

now by removing proportionality sign

\dfrac{dT}{dt}=-k(T-T_o)

Now by separating variables

\dfrac{dT}{(T-T_o)}=-k\ dt

\int \dfrac{dT}{(T-T_o)}=-\int k\ dt

So

\ln (T-T_o)=- k\ t +C

Where C is constant

T=T_o+C'e^{-kt}

C' is also a constant and it can be find by using boundary conditions.
