Negative charge −Q is distributed uniformly over the surface of a thin spherical insulating shell with radius R.

Mathematics
1 answer:
Diano4ka-milaya [45]3 years ago
4 0

Answer:

-(1/4πϵ0)Qq/r^2

Step-by-step explanation:

Firstly we have to assume the uniform shell of radius R as point charge as the point charge.

Then apply coulomb equation of electrostatic charge (Fe=q1q2/4πϵ0r2) where the q1 and q2 are point charges and r is the distance from the centre of charges.

But remember there's a condition that r>>R otherwise the charge will get non-uniformely distributed.

How do you find the area of this triangle.
Kazeer [188]

Answer:

45

Step-by-step explanation:

To find the area of any right triangle, meaning a triangle with a right angle, you use 1/2 base x height

So... here the base is 9 and the height is 10

Therefore: 1/2 x (9) x (10)

1/2 x 90

= 45

To make orange fizz, Noah mixes 4 scoops of powder with 6 cups of water. Andre mixes 5 scoops of powder with 8 cups of water. Pa
n200080 [17]

Answer:

The tables are given below and

since,

 \frac{4}{6} = \frac{16}{24} > \frac{15}{24} = \frac{5}{8}

so, Noah's mixture will taste more like orange, than Andre's mixture.              

 

Step-by-step explanation:

To make orange fizz, Noah mixes 4 scoops of powder with 6 cups of water, Andre mixes 5 scoops of powder with 8 cups of water.

so, can construct the following tables -

A) table that shows  different amounts of powder and water that taste the same as Noah's mixture :-

Serial no.  Powder in  scoops       cups of water

      1                 8                                   12

      2               12                                   18

      3               16                                    24

      4.               20                                   30

      5.               24                                   36              

B) table that shows  different amounts of powder and water that taste the same as Andre 's mixture :-

Serial no.  Powder in  scoops       cups of water

      1                 10                                   16

      2                15                                   24

      3                20                                   32

      4.               25                                   40

      5.               30                                   48

C) Since,

 \frac{4}{6} = \frac{16}{24} > \frac{15}{24} = \frac{5}{8}

so, Noah's mixture wili taste more like orange, than Andre's mixture.

9 = |2x+3| -5 what is this answer the bars are absolute value
astra-53 [7]

Answer:

9+5=|2x+3|

14=|2x+3|

2 scenarios:

(1) 2x+3 >=0, equation is now 14=2x+3

11=2x

x=5.5

(2) 2x+3<0, equation is now 14=-(2x+3)

2x+3+14=0

2x=-17

x=-8.5
