When spring times comes around you ever be like, "k." If you feel like that every year during spring then there you go
Answer:
Tension in Cord=174 N
Explanation:
Given Data
L (Phone Cord Length)=4.89 m
m (Cord Mass)=0.212 Kg
T (Time for four trips)=0.617 s
Tension=?
Solution
V=λ×f
Answer:
Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
Scientific theories are not absolute and unquestionable truths: they are the best explanation of the data, but they can be challenged if new data is discovered or if a new theory is found that fits to and explains the data even better!
The best answer is d: this is not an accurate description of a scientific theory!
