In the oscillating spring ball system, where is the velocity of the ball the greatest?

nlexa [21]

The speed of an object in a mass-spring system is given under the function

$v = \pm \sqrt{\frac{k}{m}(A^2-x^2)}$

Here,

m = mass

k = Spring constant

A = Amplitude

x = Position

When the position is at the equilibrium point (x = 0), the speed will be maximum, and could even be expressed as

$v_{max}= A\sqrt{\frac{x}{m}}$

So the correct answer is B.

What are the differences between balloon framing and platform framing? What are the advantages and disadvantages of each? Why ha

Licemer1 [7]

Answer:

Difference : Balloon framing go through from foundation to top floor while Platform do not

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

Reason for platform framing :

Due to these advantages Platform framing has become a better choice

<u><em>Little added fire stopping</em></u><u> </u>is required in platform framing because of double tap plate present which can act as as a fire stop

<u><em>Steel beam/ glue laminated wood beam </em></u>is preferred at foundation level because wood beam under the ground will most likely shrink over time

Explanation:

Differences : Balloon framing a form of building houses using a special kind of timber construction its studs start from the foundation and go to all the way to the last floor while in Platform framing the studs are interrupted by floor platforms ( i.e. they do not go through like in Balloon framing )

advantages and disadvantages

Balloon framing : It has less vertical shrinkage ( disadvantage )

platform framing : It has more vertical shrinkage and fire stops ( advantage )

platform framing : It is easier and safer to use

Reason for platform framing :

Due to these advantages Platform framing has become a better choice

<u><em>Little added fire stopping</em></u><u> </u>is required in platform framing because of double tap plate present which can act as as a fire stop

You have just landed on Planet X. You take out a ball of mass 101 g , release it from rest from a height of 16.0 m and measure t

IRINA_888 [86]

Answer:

0.3817 N

Explanation:

Remark

One thing is certain: the ball has a mass of 101 grams wherever it is in the universe. That is not true of the force. The force on the moon is a whole lot less than it is on earth, and maybe planet x as well.

Givens

m = 101 g

vi = 0 That's what at rest means.

t = 2.91 s

d = 16 m

F= ?

Formulas

d = vi*t + 1/2*a * t^2

Force = m * a

Solution

16 = 0 + 1/2 a * 2.91^2

16 = 4.234 a Divide by 4.234

16/4.234 = a

a = 3.779

F = m * a

a = 3.779

m = 101 g = 1 kg / 1000 grams

m = 0.101 kg

F = 0.101 * 3.779

F = 0.3817N
