A person is making homemade ice cream. She exerts a force of magnitude 29 N on the free end of the crank handle on the ice-cream

maker, and this end moves on a circular path of radius 0.27 m. The force is always applied parallel to the motion of the handle. If the handle is turned once every 1.9 s, what is the average power being expended

Answer:

The average power is 15.26 W.

Explanation:

Given that,

Force = 29 N

Radius = 0.27 m

Time = 1.9 s

We need to calculate the power

Using formula of power

P=\dfrac{W}{t}

P=\dfrac{F\cos\theta \times s}{t}

P=\dfrac{F\cos\theta\times 2\pi r}{t}

Here, \theta=0^{\circ}

Where, F = force

t = time

r = radius

Put the value into the formula

P=\dfrac{29\cos0\times2\pi\times0.27}{1.9}

P=15.26\ W

Hence,  The average power is 15.26 W.

Answer:

Explanation:

force, F = 29 N

radius, r = 0.27 m

time period, T = 1.9 s

Distance = 2 x π x r = 2 x 3.14 x 0.27 = 1.696 m

velocity, v = distance / time = 1.696 / 1.9 = 0.892 m/s

Power, P = F x v

P = 29 x 0.892

P = 25.88 Watt

In the periodic, the elements are in order based on
Helga [31]

Answer: informative array

Explanation:

"The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods."

Which times and distances are represented by the function? select three options. the starting distance, at 0 hours, is 300 miles
Naya [18.7K]

The times and distances are represented by the function are

  • at 2 hours, the traveler is 725 miles from home.
  • at 3 hours, the distance is constant, at 875 miles
  • the total distance from home after 6 hours is 1,062.5 miles.

<h3>What is distance?</h3>

The distance is the length of path travelled by a body when moving with some speed and taking time t.

Given function is

D (t) = 300t +125 for 0≤t<2.5

D (t) = 875  for 2.5 ≤t≤3.5

D(t)= 75t +612.5 for 3.5<t≤6

According to the given function, for 2 hours, the traveler will travel from home,

D (2) = 300x2 +125 = 725 miles.

For time between 2.5 to 3.5 hr, the distance is constant i.e. 875 miles.

For total time 6hr, the distance travelled will be

D(6) = 75 x 6 +612.5 = 1062.5 miles.

Thus, the correct options are picked up.

The Chartered Institute of Management Accountants defines activity-based cost management as follows: "An approach to the costing
egoroff_w [7]

Answer:

ABC is the activity based accounting. It is the costing done for each separate activity which maybe unit level, batch level, product sustaining or facility sustaining.

Explanation:

The basic difference between ABC and traditional costing systems can be explained with the help of the following diagram.

Traditional Costing System

Overhead Cost Accounts (For each individual expense e.g. tax)

First Stage Allocation

  1. Cost Centers ( normally Departments)
  2. Cost Centers ( normally Departments)

N.  Cost Centers ( normally Departments)

Second Stage Allocation ( Direct Labor Or Machine Hours)

Cost Objects ( products, services and customers)

ACTIVITY BASED COSTING SYSTEMS

Overhead Cost Accounts (For each individual expense e.g. tax)

First Stage Allocation ( resource cost drivers)

  1. Activity Cost Centers
  2. Activity Cost Centers

N. Activity  Cost Centers

Second Stage Allocation ( activity cost drivers)

Cost Objects ( products, services and customers) (Direct Costs)

Four steps are involved in the design of ABC systems.

  1. identifying the major activities that take place in an organization
  2. assigning cost to cost pools / cost centers for each activity
  3. determining the cost for each major activity
  4. assigning the cost of activities to products according to the product's demand for activities.

The first two steps relate to the first stage and final two steps to the second stage of the two - stage allocation process shown above.

An object that is thrown straight up falls back to Earth. This is one-dimensional motion. (a) When is its velocity zero? (b) Doe
maw [93]

Answer:

Explanation:

(a) The velocity of object is zero when it is at maximum height.

(b) The direction of velocity changes as it starts moving downwards after it reaches the maximum height.

(c) Acceleration due to gravity always acts downwards so its sign remains same.
