Answer:
a.
Explanation:
Use accleration formula,
The initial velocity and final velocity is at zero. and t=10
So we got
so
a is the answer
Answer:
(C) Independent variable
Explanation:
Independent is the variable used by the experimenter to vary a condition of interest in the experiment (temperature in this case). This measure is varied over a sensible range to induce changes in other aspects (dependent variables; level of aggression in this case) which are measured during the experiment.
Answer:
Explanation:
Given data:
Weight W = 16 lb
length l = 6/12 = 0.5 ft
hence, spring constant k = W/l = 16/0.5 = 32 lb/ft
The equation of motion of spring is
the auxiliary equation can be written as
The discriminate of equation is
To get the value of the damping constant,
Answer:
W and X
Explanation:
When escaping a rip current, one should always walk to the side until you escape from the rip current. If you walk towards the shore, you have the ability to keep getting dragged toward the current, such as with X and Y.
They differ because they are transverse wave. That is their direction of travel is perpendicular to its vibrations.
