Answer:
Where is question 12, we need it to answer this question
Explanation:
Answer:
Angle between incident ray and reflected ray will be 104°
Explanation:
We have given angle of incidence = 52 °
From law of reflection angle of incidence will be equal to angle of reflection
So angle of reflection will be also 52°
We have to find the angle between incident ray and reflected ray
As the incidence angle and reflected angle both is from normal of the surface and opposite to each other
So angle between incident ray and reflected ray will be 52°+52° = 104°
The most effective way to clean a science desks is to use a soapy water solution to clean tables using a clean disposable paper towel. Second, after cleaning the table surface with soap or detergent and rinsing with water, disinfect tables by using a diluted bleach water solution
Answer:169.6m/s
Explanation:
Wavelength=32cm=0.32m
Frequency=580Hz
Velocity=frequency x wavelength
Velocity=580x0.32
Velocity=169.6m/s
