When a pendulum with a period of 2. s is moved to a new location from one where the acceleration due to gravity was 9.80 m/s2, its new period becomes 1.99824 s. by how much does the acceleration due to gravity differ at its new location? how is the period of the pendulum related to the length of the pendulum and the acceleration due to gravity at the location of the pendulum? what happens to the length of the pendulum as it is moved to the new location?

1. By 0.02 m/s^2

The period of a pendulum is given by:

$T=2 \pi \sqrt{\frac{L}{g}}$

where

L is the length of the pendulum

g is the gravitational acceleration

Initially, we know:

T = 2.00000 s is the period of the pendulum

g = 9.80 m/s^2 is the acceleration due to gravity at the original location

We can solve the equation for L in order to find the length of the pendulum:

$L=\frac{T^2}{(2 \pi)^2}g=\frac{(2.0000 s)^2}{(2 \pi)^2}(9.80 m/s^2)=0.99396 m$

The length of the pendulum does not change when it is moved to the new location, so we can use the same equation with T=1.99824 s (the new period) and solving it for g to find the acceleration due to gravity at the new location:

$g=L\frac{(2 \pi)^2}{T^2}=(0.99396 m)\frac{(2 \pi)^2}{(1.99824 s)^2})=9.82 m/s^2$

So, the change in gravitational acceleration is

$\Delta g = g_2 - g_1 = 9.82 m/s^2-9.80 m/s^2 = 0.02 m/s^2$

2) the period of the pendulum is directly proportional to the square root of the length, L, and inversely proportional to the square root of the gravitational acceleration, g.

The period of a pendulum is given by:

$T=2 \pi \sqrt{\frac{L}{g}}$

where

L is the length of the pendulum

g is the gravitational acceleration

So, we see that the period of the pendulum is directly proportional to the square root of the length, L, and inversely proportional to the square root of the gravitational acceleration, g.

3) The length of the pendulum does not change

The length of the pendulum does not depend on the location: in fact, only the value of the gravitational acceleration, g, depends on the location, therefore the length of the pendulum, L, does not change.

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account. she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem. she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem. her desire for the new hairstyle is in conflict with her honesty and integrity.

d. if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it. the amount she has in her account is not the problem. and if i may suggest, she might as well close her checking account, and put the money where it'll work for her. it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now. under no circumstances should he ask for a higher limit.

b. he can ask for the grace period to be extended. but that's no solution, the bank will almost certainly refuse anyway, and there are much better options. he knew the rules of his credit card when he started using it.

c. he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d. he definitely should pay the minimum otherwise they could shut down his card. he should also pay as much more as he possibly can. he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices. what he has to do: pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
