Prime meridian (lines of longitude) would be represent by 180 degree
Answer: Option C
<u>Explanation:</u>
The longitudes are vertical lines, and they intersect with latitudes to form grids. Sunlight takes about 4 minutes to pass from one grid to another. So, they are designated either West or East, besides their number in order to identify the location.
East longitudes cover 180 degrees and West ones cover west. So, totally there are 360 degree longitudes, having one standard one, called Prime Meridian. The Prime Meridian stays at the center of the earth, and hence termed as the center longitude and noble of all the verticals.
Answer:
Push and pull are both forces, but the difference is in their direction at which it is applied. If the force applied in the direction of motion of the particle then we call it push. If that force applied in the direction OPPOSITE to the motion of the particle then it it termed as pull
Answer:
the charge of the particle is 2.47 x 10⁻¹⁹ C
Explanation:
Given;
mass of the particle, m = 6.64 x 10⁻²⁷ kg
velocity of the particle, v = 8.7 x 10⁵ m/s
strength of the magnetic field, B = 1.3 T
radius of the circle, r = 18 mm = 1.8 x 10⁻³ m
The magnetic force experienced by the charge is calculated as;
F = ma = qvB
where;
q is the charge of the particle
a is the acceleration of the charge in the circular path
Therefore, the charge of the particle is 2.47 x 10⁻¹⁹ C
