Reflection- serious thought or consideration
Absorption- the process or action by which one thing absorbs or is absorbed by another.
Diffusion- the spreading of something more widely.
Diffraction- 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.
Refraction- measurement of the focusing characteristics of an eye or eyes
Answer:
The acceleration of the box is 1.125 m/s² towards right.
Explanation:
Mass of the box, 
kg
Force acting towards right, 
N
Frictional force acting towards left, 
N
Let the acceleration be 
m/s².
Now, net force acting on the box towards right is given as:
From Newton's second law of motion,
Therefore, the acceleration of the box is 1.125 m/s² towards right.
Answer:
7. free fall -- h. 9.8m/s^2
3. Velocity -- x. 60 km/hr west
6. Acceleration -- d. change in velocity/time
8. Centrifugal -- s. towards the centre
13. Work done --w. Force * displacement
5. Uniform circular motion --j. spin cycle in washer
18. Power -- r. kW an hour
7. g -- a. 10N
hope this helps
Answer:
thermal
Explanation:
when an object's atoms move it causes friction, when friction happens, it heats ups causing thermal energy
Answer:
Sometimes atoms gain or lose electrons. The atom then loses or gains a "negative" charge. These atoms are then called ions. Positive Ion - Occurs when an atom loses an electron negative charge it has more protons than electrons.
