Omg ur keeping me awake with these notifications!! LOL :-D. JK
Arc RQ is a [minor arc] only because it is less than half the circle, which is 180 [PQ]
** remember that 180° always = half a circle
Answer:
Electric force = 8.20x10⁻⁸ N
Gravitational force = 3.61x10⁻⁴⁷ N
Step-by-step explanation:
1. The electric force can be found using the following equation:

Where:
K: is the Coulomb's constant = 9x10⁹ N.m²/C²
: is the charge of the proton = 1.6x10⁻¹⁹ C
: is the charge of the electron = -1.6x10⁻¹⁹ C
d: is the distance = 5.3x10⁻¹¹ m
Hence, the magnitude of the electric force is:
2. The gravitational force can be calculated as follows:

Where:
: is the electron's mass = 9.1x10⁻³¹ kg
: is the proton's mass = 1.67x10⁻²⁷ kg
G: is the gravitational constant = 6.67x10⁻¹¹ N.m²/kg²
Therefore, the gravitational force is:

As we can see, the gravitational force is much less than the electric force.
I hope it helps you!
Answer:
The probability of rolling factors of 5 is 1/3.
Step-by-step explanation:
There are 6 sides of a dice. 5 has 2 factors, 1 and 5.
The chance of rolling a factor of 5 is 2 out of 6.
2 out of 6 = 2/6 = 1/3
The probability of rolling factors of 5 is 1/3.
Answer:
Option (C)
Step-by-step explanation:
From the picture attached,
Two lines 'h' and 'k' are the parallel lines and a transversal 'n' is intersecting these parallel lines at two distinct points.
By the theorem of alternate interior angles, angle 8 and angle 11 will be equal in measure.
∠8 ≅ ∠11 [Alternate interior angles]
m(∠8) = m(∠11) = 118°
Therefore, Option (C) will be the answer.
