If a body has angular frequency of L. rpm, then find the time period and Angular velocity​

Answers 1

Answer:

Angular velocity is defined as the rate of change of angular displacement with respect to time. It is usually expressed by a Greek letter (omega).

Mathematically, angular velocity is ω=dθ/dt

If a body is rotating at the rate of N r.p.m. (revolutions per minute), then its angular velocity,

ω=

60

2πN

rad/s

pls amrk me as th ebrainlest

Step-by-step explanation:

given curve y= x^2-4x+3

differentiate wrt x to get gradient,

dy/dx = 2x-4

2a-4= -1

a= 3/2

AB is parallel to CD and PQ is transversal, find x and y(pls ignore my handwriting hehe) ​

Answer:

x=26 y=87

Step-by-step explanation:

here,

2x+35+3x+15=180. (linear pair also it is 3x+5 because of transversal rule)

so, 5x+50=180

5x=180-50

5x=130

thus, x=26

now ,

y+3x+15=180. (same side of the transversal)

y+78+15=180

y+93=180

y=180-93

y=87

Answer:

The value of x=26 and y= 87 .

Step-by-step explanation:

(2x+35)+(3x+15)=180. ……… suplimentry angles

5x+50 = 180

5x = 180 - 50

5x = 130

x = 26

By putting the value of "x" in equation (1), we get

= 2(26) +35

= 52+35

y = 87. ........ corresponding angles
On 1st April 2018 Vikram & Brothers purchased two machines of ₹ 80,000 and 60,000 respectively. On 1st October, 2019 1st machine (costing 80,000) was sold for 62,000 and on the same date another machine was purchased for 70,000. On 1st October 2020 second machine (original cost * 60,000) was sold for 35,000. Depreciation is charged at 10% p.a. by straight line method. Prepare Machinery Account for 2018-19, 2019-20 and 2020-21. Accounts are closed on 31st March every year. ​

Explanation:

1) Calculation of Sale proceeds from Machinery sold on 1st April, 2017

Book Value of the Machine as on 1st April, 2017

=(Total opening balance of Machinery on this date/5)

=₹ (2,40,000/5) = ₹ 48,000

Loss on Sale of Machinery=₹ 8,000

Sale proceeds from the Machinery=Book Value of the Machine as on 1st April, 2017 – Loss on Sale

=₹ (48,000 – 8,000) = ₹ 40,000

2) Calculation of Sale proceeds from Machinery 

Book Value of the Machine as on 1st July, 2018=[(Total opening balance of Machinery on this date/4) – Depreciation]

=₹ [(1,68,000/4) – 1,500]

= ₹ 40,500Loss on Sale of Machinery

=₹ 12,500

Sale proceeds from the Machinery=Book Value of the Machine as on 1st July, 2018 – Loss on Sale

=₹ (40,500 – 12,500) = ₹ 28,000

If $5000 is invested now in common stockthat is expected to yield $100 per year for10 years and $7000 at the end of 10 yearswhat is the rate of return.
a b and c were in partnership sharing profits and losses in the ratio of 4:3:1 it is provided under partnership deed that on the death of any partner firm's goodwill is to be valued on basis of share of such partner's share of 2 years' profits calculated on the average of 4 completed year's profit immediately preceding the year of death less 20%. B died on 1 march 2013 the result of the firm's trading profit for the last four years were as follows:2009:190000; 2010: 120000 ; 2011:30000(loss) ;2012:200000. Determine the amount that should be credited to B in respect of his share of goodwill. also pass a journal entry for goodwill, assuming that the profit sharing ratio of A and C in future ill be equal.
