Answer:
b)3:2
Explanation:
The dispersive power is the reciprocal of the focal length:
Given the ratio of focal lengths:
Therefore,
P₁ : P₂ = 3 : 2
Hence, the correct option is:
<u>b)3:2</u>
Hi there!
Since the ball is directed 60° above the horizontal, we must use its HORIZONTAL component to find its displacement.
We can take the cosine to do so:
vcosθ = 28.3cos(60) = 14.15 m/s
Since the ball is in the air for 5 sec, we can use the following equation:
displacement = velocity · time (d = vt)
Plug in the values:
d = 14.15 · 5 = 70.75 m
You have to create table using cubic meters and the unit Kelvin to measure the temperature.
