Answer:
The third choice: 
Explanation:
The cork is positively charged, therefore we know tat there must be excess of positively charged protons present.
The charge 
of a proton is
;
therefore, the number 
that makes up a charge of 
is
which is the 3rd choice.
6 chairs will fit across the platform.
<h3>Calculation</h3>
We have a school stage of 8 3/4 feet wide.
It's also given that each chair is 1 5/12 feet wide.
To find out the number of chairs possible we can simply divide the total length available by width of the chair.
8 3/4 = 35/4
1 5/12 =17/12
So, 35/4 / 17/12
So, the final answer comes up to 6.
so, the total number of chairs that would fit in are 6.

Answer:
Newton's law of cooling says that the temperature of a body changes at a rate proportional to the difference between its temperature and that of the surrounding medium (the ambient temperature); dT/dt = -K(T - Tₐ) where T = the temperature of the body (°C), t = time (min), k = the proportionality constant (per minute),

What happens to baking soda when you heat it up!
When you heat up baking soda, it loses carbon dioxide which tends to crest bubbles. This is what makes it quite light and fluffy.

Answer:
26m
Explanation:
Given parameters:
Acceleration = 7.7m/s²
Initial velocity = 0m/s
Final velocity = 20m/s
Unknown:
Distance traveled = ?
Solution:
To solve this problem, we use the expression below:
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
20² = 0² + (2 x 7.7 x S)
400 = 15.4S
S = 26m
