Answer:
Transfer
Explanation:
bc energy cannot be created not destroyed so instead it transforms or gets transferred.
In a mirror, the light ray undergoes reflection, in a glass block, the light ray undergoes refraction. For a prism, a light ray undergoes refraction and dispersion and in a glass box with a smooth surface, it may experience both reflection and refraction.
These processes of reflection, refraction, and dispersion may take place when the ray of light from the ray box is aimed at each of the objects:
Mirror: when a light beam strikes a mirror, it is reflected and reflects at an angle that is equal to the angle of incidence. According to the law of reflection, the angle of reflection and incidence are the same.
Glass Block: when a light beam penetrates a glass block at an angle, it changes direction as a result of the difference in light speed between the different media (glass and air). Refraction is the name given to this phenomenon. If the light in the glass slows down, the ray bends toward the normal, and if it speeds up, it bends away from the normal. The incidence angle and the glass's refractive index both affect how much bending occurs.
Prism: when a light beam enters a prism, it undergoes refraction as it transitions from air to the denser prism material. The rise in refractive index causes the ray to bend in the direction of the prism's base. Dispersion, or the separation of light into its individual colors (rainbow), is another effect of the prism. This occurs as a result of the various wavelengths of light diffracting differently as they pass through the prism. The stunning array of colors that occurs when light passes through a glass prism is caused by this phenomenon.
Hence, in a mirror, the light ray undergoes reflection, in a glass block the light ray undergoes refraction. For a prism, a light ray undergoes refraction and dispersion and in a glass box with a smooth surface, it may experience both reflection and refraction.

Answer:
The mass of the object is 18.26kg
Explanation:
We know by Newton's second law we know that a force applied on an object is equal to its mass times the acceleration caused by the force:
From this equation, solving for the mass:
Plugging in the values:
The answer is :
18.26
Hope I helped.
Like an animal cell:
Solution:
Step wise solution
Let r1 be the distance from the Earth to the point where
the gravitational accelerations are the same and let r2 be the distance
from the Moon to that point.
Then, r1+ r2 = r12 = 383,000 km.
Let Re be the radius of earth
and let Rm be the radius of moon
Let, ge be the gravity of earth
and let gm be the gravity of moon
The fact that the gravitational attractions by the Earth and the Moon
at this point are equal leads to the equation
gE(Re/r1)=gM(Rm/r2)
9.8(6380/r1)=1.62(1738/r12-r1)
(here, Re=6380, gE=9.8m/s^2, gM=1.62m/s^2 and r12=383,000 km
9.8*6380/(1.62*1738)=r1/(383000-r1)
therefore,
r1=344,770 km
Hope this answer wil help you
