Answer:
I think it is C.
Explanation:
I took a 12 question quiz in USA TP and made a 92%. It won't let me see which one I missed though.
Look up habitat fragmentation and think about how well it answers the question given.
Answer:
False. the system does not complete the circle movement
Explanation:
For this exercise, we must find the rope tension at the highest point of the path,
-T - W = m a
The acceleration is centripetal
a = v² / R
T = ma - mg
T = m (v² / R - g)
The minimum tension that the rope can have is zero (T = 0)
v² / R - g = 0
v = √ g R
Let's find out what this minimum speed is
v = √ 9.8 1
v = 3.13 m / s
We see that the speed of the body is less than this, so the system does not complete the movement.
The amount of force required is 69J
Answer:something empty depressed
Explanation:
Answer:
Explanation:
Use the velocity formula to solve
In this question, you are given velocity 
, and you are given a distance, 
. Time in this question is what you'll need to find.
Start by rearranging the velocity formula, to isolate for t.
Start by multiplying both sides by t
Then divide both sides by v.
Now that you've isolated for time, sub in your values and calculate.
