The heat from your body is causing the ice cube to melt
'The normal is a line perpendicular to the surface of the mirror'.This is the correct statement that corrects an error on the site.
<h3>What is the law of reflection?</h3>
The law of reflection specifies that upon reflection from a downy surface, the slope of the reflected ray is similar to the slope of the incident ray.
The reflected ray is consistently in the plane determined by the incident ray and perpendicular to the surface at the point of reference of the incident ray.
When the light rays descend on the smooth surface, the angle of reflection is similar to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in a similar plane.
Hence 'The normal is a line perpendicular to the surface of the mirror'.This is the correct statement that corrects an error on the site

The answer is (a).
Golf balls have a higher density than water hence sink to the bottom.
Earth's inner core is solid even though the temperature is so high because the pressure is also very high.

Answer:
271248.75 N
Explanation:
= Density of air = 1.14 kg/m³
v = Velocity of wind = 45 m/s
A = Area = 235 m²
From Bernoulli's principle we have the relation
Force is given by
Force due to the jet stream on the roof is 271248.75 N
