Answer:
1. 23°
2. 65°
Explanation:
1.
The law of reflection provides that for the same medium, the angle of reflection equals the angle of incidence.
Similarly, here, angle of incidence and reflection will be 46°÷2=23°
2. Since the normal, angles of reflection and incidence lie on the same plane and also the angles of reflection and incidence are equal then the angle between the plane of the mirror and the reflected beam will be given by 90-25=65°
Answer:
The answer is: Pressure increases linearly with the depth
Explanation:
In this case, the definition of pressure is:

where F = mg is the weight of the fluid over the body, and A is the area of the surface to which the force is exerted. If we consider
, then
.
Volume can be expressed as V = A*h, where A is the cross section of the column of the fluid over the body and h is the height of the column, in other words, the depth.
So
,
which means that pressure increases linearly with the depth in a factor of
.
3108 N
Force Formula= mass (kg) × acceleration (m/s²).
So according to the formula, this is our equation
444*7.0 m/s² =
3108N
The sun's radiation is made up of rays of many different wavelengths.
