Answer:
θ = 18.3°
Explanation:
The angle can be found by using the formula for the range of projectile motion:
where,
R = Horizontal Range = 8.75 m
u = launch speed = 12 m/s
g = acceleration due to gravity = 9.81 m/s²
θ = launch angle = ?
Therefore,
θ = 18.3°
Since this angle is less than 45°. Therefore, it is the smaller of the two possible angles an dit is the correct answer:
<u>θ = 18.3°</u>
Answer:
Distance,
Explanation:
It is given that,
Charge,
Area of the parallel plate capacitor,
We need to find the distance between the plates. Let it is equal to d. The capacitance of the parallel plates capacitor is given by :
k = relative permittivity, for air k = 1
So, the distance between plates is . Hence, this is the required solution.
Answer:
the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced. Diffraction refers to various phenomena that occur when a wave encounters an obstacle or opening. It is defined as the bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture.
Explanation: FYI I gave you the def and what it refers to BTW
