The pictorial and physical model help in many ways when we solve physics problems.

A pictorial representation of data refers to the presentation of data in different symbols or pictures of different objects.It gives the idea of deeper understanding of the problem. It makes the data clear and useful,and helps in comparing it with different parameters.

A physics problem is not always full with digits and equations.Sometimes a problem require higher understanding .Physical model plays a crucial role in this situation.It eradicates all the ambiguity and provides the idea to solve the problems pragmatically.

Answer:

30 degrees

Explanation:

Reflects off of mirror 1 at 60 degrees....this makes it incident to second mirror at 30 degrees ....then angle of reflection equals this angle of incidence = 30 degrees

Un avión de rescate en Alaska deja caer un paquete de provisiones a un grupo de exploradores extraviados. Si el avión viaja hori

posledela

Answer:

180.4 m

Explanation:

The package in relation to the point where it was released falls a certain distance that is calculated by applying the horizontal motion formulas , as the horizontal speed of the plane and the height above the ground are known, the time that It takes the package to reach its destination and then the horizontal distance (x) is calculated from where it was dropped, as follows:

$V_{ox}=v_x = 40 \ m/s$

h = 100 m

x =?

Height formula h:

$h=g \times \frac{t^2}{2}$

Time t is cleared:

$t = \sqrt{\frac{2h}{g}}$

$t = \sqrt{\frac{2 \times 100}{9.8}}$

t = 4.51 sec

Horizontal distance formula x:

$x=V_x \times t$

x = 40 m / sec x 4.51 sec

x = 180.4 m
