During a baseball game, a batter hits a high
2 answers:
Answer:
The maximum height of the ball is 36.65 m.
Explanation:
Given that,
Time = 5.47 sec
The ball must be at top point in half of total time.
We need to calculate the height
Using equation of motion
Where, s = height
u = initial velocity
g = acceleration due to gravity
Put the value in the equation
Hence, The maximum height of the ball is 36.65 m.

Answer:
The angle between the electric field and the axis of the filter is 54⁰
Explanation:
Apply the equation for intensity of light through a polarizer.
where;
I is the intensity of the transmitted light
I₀ is the intensity of the incident light
θ is the incident angle
If only 35 % of the intensity of a polarized light wave passes through a polarizing filter, then the ratio of the intensity of the transmitted light to that of the intensity of the incident light is given by;
Therefore, the angle between the electric field and the axis of the filter is 54⁰
