the answer is d it reflects all the wavelengths of visible light.
Answer:
Motion with constant velocity of magnitude 1 m/s (uniform motion) for 4 seconds in a positive direction and then for 2 seconds uniform motion with constant velocity of magnitude 3 m/s in reverse direction .
Explanation:
The graph shows a constant velocity of 1 m/s for 4 seconds in the positive direction. After that, between 4 seconds and 6 seconds, the object reverses its motion with constant velocity of magnitude 3m/s.
Answer:
Explanation:
This question seek to test the difference between a scalar and a vector quantity. A scalar quantity is a quantity that has just magnitude but no direction while a vector quantity is a quantity that has both magnitude and direction. Example of a scalar quantity is speed while example of a vector quantity is velocity.
Hence, it can be that <u>speed has magnitude but no direction while velocity has both magnitude and direction</u>.
They both have the same formula which can be written as
speed = distance ÷ time
OR as
velocity = distance ÷ time
Balanced Forces are different from Unbalanced Forces because Balanced Forces are two forces acting in opposite directions of an object, and equal in size.On the other hand unbalanced forces are forces that cause a change in the motion of an object.
This impacts motion because when balance forces enter,... the object either stops (Stays at rest or moves at the same speed and direction) Unbalanced Forces causes an object to move faster/slower (might change the direction),.. due to one side having more force than the other.
