B
A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona.

Answer: discplacement/change in time = average velocity.
Explanation:
There is a formula for velocity which is given above
Answer:
Explanation:
Horizontal velocity V_x = 4.5 x 10⁵ m /s
vertical electric field E_y = 9.6 x 10³ N/C
acceleration in vertical direction a_y = force on proton / mass
= 9.6 x 10³ x 1.6 x 10⁻¹⁹ / 1.67 x 10⁻²⁷
= 9.2 x 10¹¹ m /s²
a ) In horizontal direction it will move with uniform velocity
time required = distance / velocity
= 5 x 10⁻² / 4.5 x 10⁵
= 1.11 x 10⁻⁷ s
b )
vertical displacement in time 1.11 x 10⁻⁷ s
h = 1/2 x at² , initial vertical velocity is zero.
= .5 x 9.2 x 10¹¹ x ( 1.11 x 10⁻⁷ )²
= 5.66 x 10⁻³ m
5.66 mm
c )
Horizontal velocity will be unchanged ie 4.5 x 10⁵ m /s
vertical velocity will change due to acceleration
= u + at
0 + 9.2 x 10¹¹ x1.11 x 10⁻⁷
= 10.21 x 10⁴ m / s
= 1.021 x 10⁵ m /s
