The other lights wouldn't be affected?

If all bulbs are on the same wire then the current will not pass through the wire further than the bulb this is also called a series circuit

A salt shaker sits 0.102 m from

Ivahew [28]

The maximum speed is 0.55 m/s

Explanation:

For an object in uniform circular motion, the force of friction between the object and the ground provides the centripetal force required to keep the body in motion. Therefore we can write:

$\mu_s mg = m\frac{v^2}{r}$

where the term on the left is the frictional force and the term on the right is the centripetal force, and where

$\mu_s$ is the coefficient of static friction

m is the mass of the body

g is the gravitational acceleration

v is the speed of the body

r is the radius of the circular path

In this problem, we have:

$\mu_s = 0.307$

r = 0.102 m

$g=9.8 m/s^2$

Substituting and re-arranging, we find the maximum speed v at which the salt shaker can rotate:

$v=\sqrt{\mu gr}=\sqrt{(0.307)(9.8)(0.102)}=0.55 m/s$

A group of friends wants to go to the amusement park. They have no more

Mumz [18]

Answer:

p ≤ 8

Explanation:

Let's go over what we know that can help us build an inequality:

we know that these friends can spend no more than $325, meaning that they can either spend exactly $325, or they could spend less. This is our first clue, that one side of the inequality will be 325, and that the inequality sign will be less than or equal to ( ≤ ) :

amount spent ≤ 325

Now, we want to figure out how many people can go (p)--but there's something we need to consider first--the parking.

Assuming that all friends take one car, we know we will have 11 dollars less to spend on admission (you can write this two ways).

amount spent on tickets + 11 ≤ 325

or, we can simplify it:

amount spent on tickets + 11 ≤ 325

- 11 -11

amount spent on tickets ≤ 314

(I will be using the second way, you could always plug it back into the first way though)

now, we know that each "p" that we include will be multiplied by 39.25

Why? Imagine we have one p (one person), they will cost 39.25, so we could write that as (p · 39.25) , ( 1· 39.25 ) -- we use × because that's how many times we're adding the number. If we have two p, we could write it as (2p · 39.25)--there's an easier way to do this though

So, we can write "p" to stand for all possible values of p possible,

p · 39.25 ≤ 314 (we write this slightly differently):

39.25p ≤ 314

Now, let's simplify!

39.25p ≤ 314

÷ 39.25 ÷ 39.25 (divide by 39.25 to isolate p)

p ≤ 8

So, we know that the number of friends admitted must be less than or equal to 8, expressed as:

p ≤ 8

hope this helps! let me know if you need clarification on anything :)
