Answer:
(C) zero (there is no net horizontal component of the E-field)
Explanation:
If we subdivide the bar into small pieces, each piece (dx) contains a charge (dq), the electric field of each piece is equivalent to the field of a punctual electric charge, and has a direction as shown in the attached figure. For each piece (dx) in the negative axis there is another symmetric piece (dx) in the positive axis, and as we see in the figure for symmetry the sum of their electric fields gives a resultant in the Y axis (because its components in X are cancelled by symmetry).
Then the resultant of the electric field will be only in Y.
(C) zero (there is no net horizontal component of the E-field)
Answer:
Explained below:
Explanation:
When a cold air mass meets a warm air mass, a front is formed and if the cold air is replacing the warm air, it is known as a cold front. Cold fronts frequently cause thunderstorms or rain showers because they pressure the air in a steep upward direction at the front's edge. They are also responsible to bring the changes in atmospheric pressure and wind direction.
m = mass of the cat being lifted = 5 kg
h = height to which the cat is raised into air = 2 m
g = acceleration due to gravity of earth = 9.8 m/s²
U = gravitational potential energy gained by the cat
Gravitational potential energy gained by the cat is given as
U = m g h
inserting the values in the above equation
U = (5 kg) (9.8 m/s²) (2 m)
U = (5 x 9.8 x 2) (kg m²/s²)
U = 98 J
Heyy! :) I'm Jenna, and Im here to help you on your Math problem!
It says that he/she bought 2 $27 bingo games so thats 27 times 2 which equals:
