6. Which Thanksgiving dish contains the most dietary fiber ? (Corn) (Mashed Potatoes) (Sweet Potatoes) (Pecan Pie)

pashok25 [27]

Answer:

The correct option is;

Sweet Potatoes

Explanation:

The dietary fiber in Corn = 2.7 g per 100 g

The dietary fiber in Mashed Potatoes = 1.3 g per 100 g

The dietary fiber in Sweet Potatoes = 3 g per 100 g

The dietary fiber in Pecan Pie = 2.1 g per 100 g

Therefore, the Thanksgiving dish that contains the most dietary fiber per 100 g is Sweet Potatoes

Calculate the displacement of a motorcycle that accelerates forward from rest to 7.0 m/s in 3.5 s.

Harrizon [31]

Answer:

12.25 meters

Explanation:

s=1/2(v+u)t

s= displacement

v= final velocity

u= initial velocity

t= time

7m/s+0m/s divide by 2= 3.5 m/s velocity Times 3.5 seconds= 12.25 meters

When mapping the equipotentials on the plates with different electrode configurations you may find that some have significant ar

Olenka [21]

Answer:

v = 10 V and E = 2 10³ N/C

Explanation:

The electrical potentials and the electric field at one point are related by the expression

ΔV = - ∫ E. dS

Where the bold indicates vector quantities, E is the electric field and S is the line of displacement of the load, in general displacement is perpendicular to the equipotential lines, which reduces the product scales to the ordinary product.

If the potential difference is the most usual that is V = 10 V, the electric field is

s = 0.5 cm = 0.5 10⁻² m

E = ΔV / S

E = 10/0.5 10⁻²

E = 2 10³ N / C

A roller coaster has a "hump" and a "loop" for riders to enjoy (see picture). The top of the hump has a radius of curvature of 1

nikklg [1K]

Answer:

Part a)

$F_n = 306 N$

Part B)

$v = 12.1 m/s$

Explanation:

Part A)

At the top of the hump the force on the rider is

1) Normal force

2) weight

so here we know that

$mg - F_n = \frac{mv^2}{R}$

$F_n = mg - \frac{mv^2}{R}$

$F_n = (100)(9.81) - \frac{100(9^2)}{12}$

$F_n = 306 N$

Part B)

At the top of the loop we will have

$F_n + mg = \frac{mv^2}{R}$

in order to remain in contact the normal force must be just greater than zero

so we will have

$mg = \frac{mv^2}{R}$

$v = \sqrt{Rg}$

$v = \sqrt{15\times 9.81}$

$v = 12.1 m/s$

Assume it takes 8.00 min to fill a 50.0-gal gasoline tank. (1 U.S. gal = 231 in.3) (a) Calculate the rate at which the tank is f

vagabundo [1.1K]

The volumetric rate or flow rate of a fluid is defined as the amount of the volume of a fluid circulating on a surface per unit of time. In this case we have units given initially: Gallons and minutes. For the first part we will convert the minutes to seconds, and we will obtain the flow rate under that measure. For the second case we will convert the gallons to cubic meters and obtain the desired value. Recall the following conversion rates,

$1 min = 60s$
