Answer:
a)
346.67 N/C, downward
b)
1.3 m
Explanation:
(a)
q = magnitude of charge on the particle = 1.95 x 10⁻⁹ C
r = distance of location from the charged particle = 0.225 m
E = magnitude of electric field at the location
Magnitude of electric field at the location is given as
Inserting the values
E = 346.67 N/C
a negative charge produce electric field towards itself.
Direction : downward
(b)
E = magnitude of electric field at the location = 10.5 N/C
r = distance of location from the charged particle = ?
q = magnitude of charge on the particle = 1.95 x 10⁻⁹ C
Magnitude of electric field at the location is given as
Inserting the values
r = 1.3 m
Answer:
Silk fibre is obtained from <u>silkworms</u>
whereas artificial silk is obtained by
chemical treatment of <u>wood pulp/cellulose.</u>
Explanation:
Artificial silk, or rayon, is made from cellulose, obtained from cotton or wood pulp.
So any one of them in 2nd blank is correct.
Black holes is exists
Black holes is highly gravitional wave field in space
Ocean currents can be generated by wind, density differences in watermasses caused by temperature and salinity variations, gravity, and events such as earthquakes
Answer:
Opposite to the direction that you are pulling
Explanation:
Static friction acts in the opposite direction to the acceleration.
Kinetic friction acts in the opposite direction to the velocity.
