Terminal velocity is described as a velocity attained when an object which falls freely experiences 0 net force owing to gravitational force which is balanced by the resistance of the air. Hence, there is no acceleration thus, the velocity is constant. In order to attain terminal velocity by the skydiver, the weight of the skydiver must be equal to the resistance of the air hence we have the equation below;
50 kg*9.8 m/s²= 490 Newton.
Summarily, the force or magnitude of the air resistance is 490 Newton
Answer:
Uses the law of superposition to determine which rock is older or younger.
Explanation:
Relative age refers to the age of the rock when compared to other rocks. The law of superposition was developed by Nicholas Steno. In this process, you determine which rock layer is older or younger in terms of the sequence they were laid out or layers were formed. This law states that the lower the layer, the older the rock layer is as compared to those on top of it.
<u>Speed</u> — it's defined as the rate of change of distance with respect to time.
Fish, penguins, and dolphins all have the same basic shape because they all faced the same physical constraints during their evolution and converged upon the same body plan.
