Distance is a scalar as it provides magnitude without direction
Ex. 5 m
Displacement is a vector as it has magnitude and direction
Ex. 5 m [N]
Answer:
Explanation:
<u>Mechanical Force</u>
According to the second Newton's law, the net force F exerted by an external agent on an object of mass m is:
F = m.a
Where a is the acceleration of the object.
Assume we apply some given force F to an object of m1=1 Kg that produces an acceleration , then:
F = m1.a1
The same force F is now applied to a second object m2=4 Kg that produces an acceleration a2, then:
F = m2.a2
Dividing both equations:
Solving for a2:
Substituting values:
Sand
dead creatures
polluted coral reefs will die
REMEMBER...CORAL ARE LIVING
Heat flows naturally from a warmer object (higher energy) to a cooler one (lower energy).
