Answer:
Explanation:
The centripetal acceleration requirement must equal gravity at the top of the circle
mg = mv²/R
v = √Rg
v = √(1.0(9.8))
v = 3.1304951...
v = 3.1 m/s
Answer:
The slope of a distance-time graph indicates the rate of change of distance and it is termed as speed.
pls mark as brainliest
the answer should be "fluids".
Answer:
35.7 mA
Explanation:
The magnetic field inside a solenoid is given by:
(1)
where
is the vacuum permeability
I is the current
n is the number of turns per unit length
Since we have
N = 870 turns
L = 0.390 (length of the solenoid)
we can calculate n

And now we can re-arrange eq.(1) to find the current, I:
