The sun, fire and lamp because they generate their own light.
Answer:
a = 1.055 x 10¹⁷ m/s²
Explanation:
First, we will find the force on electron:

where,
F = Force = ?
E = Electric Field = 6 x 10⁵ N/C
q = charge on electron = 1.6 x 10⁻¹⁹ C
Therefore,

F = 9.6 x 10⁻¹⁴ N
Now, we will calculate the acceleration using Newton's Second Law:

where,
a = acceleration = ?
m = mass of electron = 9.1 x 10⁻³¹ kg
therefore,

<u>a = 1.055 x 10¹⁷ m/s²</u>
Answer:
3683.67 m
Explanation:
Formula for maximum height of projectile is given by the equation;
h = u²/2g
Where u is initial velocity and g is acceleration due to gravity
We are given u = 190 m/s
Thus;
h = 190²/9.8
h = 36100/9.8
h = 3683.67 m
