Answer:
The correct answer is B. Algae and fungi are biotic; temperature and rainfall are abiotic.. FURTHER EXPLANATION. An ecosystem consists of all living and non-living factors in an environment that interact and that are interdependent with each other.. All living things or factors in an ecosystem are called biotic factors.Examples include organisms like plants, animals, humans, etc.
Explanation:
Answer:
A force is a push or pull upon an object resulting from the object's interaction with another object.
Momentum is force or speed of movement.
Velocity defines the path of the motion of the frame or the object
Answer:
K.E = 1.6 x 10⁻¹⁸ J
Explanation:
given,
thickness between two plate = t = 0.1 mm
Voltage difference between two plate = 10 V
charge of proton = q = 1.6 x 10⁻¹⁹ C
When the charge moves from positive to negative the potential energy reduces to kinetic energy
K.E = Δ PE
K.E = q Δ V
K.E = 1.6 x 10⁻¹⁹ x 10
K.E = 1.6 x 10⁻¹⁸ J
so, the kinetic energy of the proton when it reaches negative plate is equal to K.E = 1.6 x 10⁻¹⁸ J
(1) Speed is the ratio of the total distance covered by the object and the total time it takes for him to finish it.
Speed = distance / time
In this item, we are given that the distance is 20 kilometers and that the time it takes for the trip is 2 hours. Substituting the known values,
Speed = 20 kilometers / 2 hours
speed = 20 km/h
(2) Velocity on the other hand takes into account the displacement of the object from his original position. It is assumed that Jeremie was basically back to his original position after two hours. Hence, the velocity is equal to zero.
