Answer:
336 hrs
Explanation:
2 weeks is 14 days. There are 24 hours in 1 day. 24 x 14 = 336
Answer:
The acceleration of object is 2 m.s^-2.
Given data:
Force on object = 80N
Mass of object = 40 kg
Acceleration = ?
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Answer:
Option D, Light must travel one path from the source to the object, and another path from the object to the eye.
Explanation:
In optical physics it has been established that whatever object/things we are able to see is because of the light reflected by the object. Thus, it is clear that either the object must throw light of itself or it should have a source of light whose light can be reflected by object. The reflected light from object then reaches the eye of the viewer and he/she visualizes the object.
Thus, option D is correct.
