Answer:
Explanation:
a.
Given the permittivity constant to be 
,The capacitance of a 
of length, 
is given by the equation:
where 
is the radius of the outer cylinder and 
the radius of the inner cylinder.
The values are given as:
Substitute in our capacitance equation:
Hence the capacitance is 
b. The charge on the capacitance is related to the potential difference across it. The potential difference is expressed using the equation:
,
From a above, we already have our capacitance value,
We substitute 
in the pd equation:
Hence, the applied potential difference is 2.7344V
Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 26 m/s
Final velocity (
V2) = 0 ft/s because the car comes to a complete stop!
Time (
t) = 6 seconds
The equation for acceleration is below!
a =
So now, just plug in the values!
a =
a =
a = -4.33 m/s²
Therefore, your acceleration is -4.33 m/s²!! Hope this helped and was one of the branliest answers :')
False because bases turn red litmus paper to blue and acids turn blue litmus paper red
If a teacher had 48 red pens and the ratio of red to blue pens she owns is 6:1, she will have a total of 56 pens
Let the number of red pens be R and the number of blue pens be B.
R = 48
R / B = 6 / 1
48 / B = 6 / 1
B = 48 / 6
B = 8
Total number of pens = Number of red pens + Number of blue pens
Total number of pens = R + B
Total number of pens = 48 + 8
Total number of pens = 56 pens
Therefore, she has a total of 56 pens

Answer:
option (E) 1,000,000 J
Explanation:
Given:
Mass of the suspension cable, m = 1,000 kg
Distance, h = 100 m
Now,
from the work energy theorem
Work done by the gravity = Work done by brake
or
mgh = Work done by brake
where, g is the acceleration due to the gravity = 10 m/s²
or
Work done by brake = 1000 × 10 × 100
or
Work done by brake = 1,000,000 J
this work done is the release of heat in the brakes
Hence, the correct answer is option (E) 1,000,000 J
