A bicycle wheel is mounted on a fixed, frictionless axle, with a light string wound around its rim. The wheel has moment of iner
xz_007 [3.2K]

The final rotational speed ω_final and the instantaneous power P delivered to the wheel are; ω_f = √((ω_i)² + 2(FL/(kmr²) and P = Frω_i

<h3>What is the Instantaneous Power?</h3>

A) From rotational kinematics, the formula for the final angular velocity is;

ω_f = √((ω_i)² + 2αθ)

where;

α is angular acceleration

θ = L/r. Thus;

ω_f = √((ω_i)² + 2α(L/r))

Now, α = T/I

Where;

I is moment of inertia = k*m*r²

T is t o r q u e = F * r

Thus;

α = (F * r)/(kmr²)

α = F/(kmr)

ω_f = √((ω_i)² + 2(F/(kmr))(L/r))

ω_f = √((ω_i)² + 2(FL/(kmr²)

B) Formula for instantaneous power is;

P = Fv

where at t = 0; v = rω_i

Thus;

P = Frω_i

Suppose a friend of yours wants to buy a crystal candlestick. You remember seeing this item at both annie's attic and betty's br
Veronika [31]

The advice that will be given in the purchase of crystal candlestick is to go to

Betty's Breakables if the price is above $25.00.

In this scenario, we were told that Betty's Breakables offers 40% discount,

while Annie Attic offers $10 discount.

<h3>Calculation</h3>

Let's assume the price is $25.00, the discount at Betty's Breakables will be

= 40/100 × $25.00

= $10.

At Annie Attic, he was offered a $10 discount which is the same. However

there will be more gain on the discount if the price is above $25.

Let's assume the price is $30 , the discount will be $12 at Betty's Breakables

which is more than that at Annie Attic in which the discount remains at $10.

It is therefore cheaper to go to Betty's Breakable if the price of the

candlestick is above $25.

UNO [17]

Answer:

A research was interested in whether there was a difference in appearance management by

gender and the situation context. For example, on a romantic date, group date or out with

friends. Using the data provided determine whether there are statistically significant

differences in appearance management (measured in seconds) by gender and situational

context. Include all four hypothesis testing steps and α = .05 level of significance.

N = 36

n = 6

K = 6

G = 258
