what is meant by emasculation??​

Answer = 1/3

Answer 1/ 3

Answer 1/3

Given,

u = 30 m/s

angle, tan = 1/8

To find,

At t = 1 sec find measure of angle a

Solution,

tanx = 1/8

sinx = 1/√65

cosx = 8/√65

Along direction of motion after t = 1 sec

v = u + at

vsina = usinx + (-g)t

vsina = 30 × 1/√65 - 10

vsina = 30/√65 - 10

vsina = (30 - 10√65)/√65                                                       (i)

Horizontal component will remain constant throughout the journey

vcosa = ucosx

vcosa = 30 × 8/√65                                                                (ii)

Dividing equation i and ii

[tex]\frac{vsina}{vcosa} = \frac{(30 - 10\sqrt{65})}{\sqrt{65}} \\[/tex] × [tex]\frac{\sqrt{65} }{240}[/tex]

sina/cosa = (30 - 10√65) / 240

tana = (30 - 10√65) / 240

a = tan⁻¹ (30 - 10√65) / 240

Angle a is given as tan⁻¹ (30 - 10√65) / 240.

Answer:

At 127° with river flow

Hope this will help you...

The speed of the swimmer is (u) = 0.6 m/s

The width of the river = 50 m

The speed of the water current is (v) = 0.36 m/s

She wants to reach on the other bank at a point directly opposite from her starting point, so the drift is = 0 m

Suppose she has to swim at an angle of θ with the river flow.

Now, u Cosθ = - v

⇒ Cosθ = - v/u

⇒ Cosθ = - 0.36/0.6

⇒ Cosθ = - 3/5

⇒ Cosθ = 127°

So, the direction in which she must swim is at 127° with river flow.

Answer:

2520

Step-by-step explanation:

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?

To find: The smallest number that can be divided by each of the numbers from 1 to 20 without any remainder.

• We just need to take L.C.M. the smallest number that can be divided by each of the numbers from 1 to 20 without any remainder.

• The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Divisor (LCD). For two integers a and b, denoted LCM(a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.

• The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set.

Let's do this in listing factors method.

Write down factoriaztion of each number:

1 = 1

2 = 2

3 = 3

4 = 2 * 2

5 = 5

6 = 2 * 3

7 = 7

8 = 2 * 2 * 2

9 = 3 * 3

10 = 2 * 5

11 = 11

12 = 3 * 2 * 2

13 = 13

14 = 2 * 7

15 = 3 * 5

16 = 2 * 2 * 2 * 2

17 = 17

18 = 2 * 3 * 3

19 = 19

20 = 2 * 2 * 5

Write the primes vertically. (As in attachment 1)

Bring down numbers in each column and multiply to get LCM. (As in attachment 2)
