Answer:
1 m/
Explanation:
The Net Force refers to the sum of all forces acting on an object. Hence,
Net Force of box
= 20 + (-9.0) [It is -9.0 as both forces are in different directions]
= 11.0 N
We also need to know that the net force on an object is equal to the product of the mass of the object and the acceleration of the object. Hence,
11.0 = 12.0
= 1 m/ (nearest whole number)
The direction changes but not the speed.
The answer is C. Filling a table with the changed and measured data values
That description of density is a true statement.
According to snells law
<span>n1 sin theta1 = n2 sin theta2
</span>n1 = 1.333 (water)
<span>n2 = 2.42 (diamond)</span>
it is given that theta =30 degrees so
by putting the values we have
<span>1.333 sin theta = 2.42 sin 30 </span>
<span>sin theta = (2.42/1.333) *0.5 =65.2 degree
</span>so our conclusion is
<span>the ray's angle of incidence θ1 on the diamond</span> = 65.2 degree.
hope this helps
