Answer:
Backwards
Explanation:
Friction always acts in the direction opposing motion so if the motion of the wagon is forward, friction acts backwards.
Answer:
5.3 x 10⁻⁹ C
Explanation:
r = radius of cylindrical shell = 10⁻⁵ m
L = length = 0.32 m
A = area
Area is given as
A = 2πrL
A = 2 (3.14) (10⁻⁵) (0.32)
A = 20.096 x 10⁻⁶ m²
d = separation = 10⁻⁸ m
= dielectric constant = 4
Capacitance is given as
eq-1
V = Potential difference across the membrane = 74 mV = 0.074 Volts
Q = magnitude of charge on each side
Magnitude of charge on each side is given as
Q = CV
using eq-1
Inserting the values
Q = 5.3 x 10⁻⁹ C
Answer:
Nebulae contribute more to stellar formation than other regions because:
Explanation:
A.They have an unlimited supply of hydrogen.
B. They are believed to be rich in hydrogen and helium.
C. They have a three strong gravitational pull.
This are the reasons that Nebulae contribute more to stellar formation than other regions.
D I think is the correct answer
If the cylinder is slightly
