Answer:
m = 12.05 kg
Explanation:
Spring constant in K, N/m
K = 200/10* 100
K = 2000 N/m
Angular Frequency = sqrt (Spring constant / (Mass )
ω = 2 π f
ω = 2π* 2.05 Hz = 12.8805 rad/s
ω^2 = Spring constant / Mass
Mass= Spring constant / ω^2
ω^2 = 165.907 rad^2/s^2
m = 2000 (N/m)/165.907 (rad^2/s^2)
m = 12.05 kg
The answer is A. locations by the ocean typically do not get as cold in the winter or as hot in the summer as locations that are located inland.
Answer:
A and B
Explanation:
The data sets that depict an accelerating object is Data Set A & Data Set B.
The both data sets show that the body is accelerating. Also, they show that the body started from rest (0m/s) at a 0sec.
Data Set A shows a non-constant acceleration which has changing amount of velocity with change in time. While Data Set B shows a constant acceleration which has constant amount of velocity with change in time.
Answer:
Balanced forces are equal and opposite forces that act on the same object. ... Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.
No additional force is required because it's already going downhill
