Answer: petals or the scent of a flower

Explanation:

because they are brightly colored it attracts pollinators. many flower produce a sweet liquid called nectar which is what insects feed on. so that also attracts them

Block m1 of mass 2m and velocity v0 is traveling to the right (+x) and makes an elastic head-on collision with block m2 of mass

Oksana_A [137]

1) In any collision the momentum is conserved

(2*m)*(vo) + (m)*(-2*vo) = (2*m)(v1') + (m)(v2')

candel all the m factors (because they appear in all the terms on both sides of the equation)

2(vo) - 2(vo) = 2(v1') + (v2') => 2(v1') + v(2') = 0 => (v2') = - 2(v1')

2) Elastic collision => conservation of energy

=> [1/2] (2*m) (vo)^2 + [1/2](m)*(2*vo)^2 = [1/2](2*m)(v1')^2 + [1/2](m)(v2')^2

cancel all the 1/2 and m factors =>

2(vo)^2 + 4(vo)^2 = 2(v1')^2 + (v2')^2 =>

4(vo)^2 = 2(v1')^2 + (v2')^2

now replace (v2') = -2(v1')

=> 4(vo)^2 = 2(v1')^2 + [-2(v1')]^2 = 2(v1')^2 + 4(v1')^2 = 6(v1')^2 =>

(v1')^2 = [4/6] (vo)^2 =>

(v1')^2 = [2/3] (vo)^2 =>

(v1') = [√(2/3)]*(vo)

Answer: (v1') = [√(2/3)]*(vo)

Electrons are emitted from a conductor when the conductor is

IRINA_888 [86]

B. Bombarded by high speed electrons.
There are already electrons with potential energy in the conductor. When it is bombarded by these high speed electrons, the potential energy is changed into kinetic energy and then the electrons are emitted from the conductor.
Hope this helps.

An insect 3.75 mm tall is placed 22.5 cm to the left of a thin planoconvex lens. The left surface of this lens is flat, the righ

nlexa [21]

Solution :

a). The focal length of the lens is given as :

$\frac{1}{f}=(n-1)\left(\frac{1}{R_1}-\frac{1}{R_2}\right)$

$\frac{1}{f}=(1.70-1)\left(\frac{1}{\infty}-\frac{1}{-13}\right)$

$f=18.57 \ cm$

The thin lens equation is :

$\frac{1}{f}=\frac{1}{d_i}+\frac{1}{d_o}$

The distance of the image from the lens is

$d_i=\left(\frac{1}{f}-\frac{1}{d_o}\right)^{-1}$

$d_i=\left(\frac{1}{18.57}-\frac{1}{22.5}\right)^{-1}$

$=1.06 \ m$

The magnification of the lens is :

$m=-\frac{d_i}{d_o}=\frac{h_i}{h_o}$

The height of the image is :

$h_i=-\frac{d_i}{d_o}(h_o)$

$h_i=-\frac{106.3 \ cm}{22.5 \ cm}(3.75 \ mm)$

$=-17.7 \ cm$

Thus, the real and the inverted image is formed at a distance of 1.06 m. And the size of the image is 17.7 cm

b). When the lens is reversed.

The focal length of the lens is given as :

$\frac{1}{f}=(n-1)\left(\frac{1}{R_1}-\frac{1}{R_2}\right)$

$\frac{1}{f}=(1.70-1)\left(\frac{1}{13}-\frac{1}{\infty}\right)$

$f=18.57 \ cm$

The thin lens equation is :

$\frac{1}{f}=\frac{1}{d_i}+\frac{1}{d_o}$

The distance of the image from the lens is

$d_i=\left(\frac{1}{f}-\frac{1}{d_o}\right)^{-1}$

$d_i=\left(\frac{1}{18.57}-\frac{1}{22.5}\right)^{-1}$

$=1.06 \ m$

The magnification of the lens is :

$m=-\frac{d_i}{d_o}=\frac{h_i}{h_o}$

The height of the image is :

$h_i=-\frac{d_i}{d_o}(h_o)$

$h_i=-\frac{106.3 \ cm}{22.5 \ cm}(3.75 \ mm)$

$=-17.7 \ cm$

Thus, when the lens is reversed, a real and an inverted image is formed at a distance of 1.06 m. And the size of the image is 17.7 cm

What do you understand by leverage?

The employment of various financial instruments or borrowed cash, or leverage, is an investing strategy that aims to improve an investment's potential return. The level of debt a company utilizes to finance its assets is another definition of leverage.

It offers a range of funding options so that the company can reach its desired earnings. Leverage is a crucial investing strategy because it enables businesses to establish a ceiling for the growth of their operations.

Leverage can be used, for instance, to support financially a new business. Purchasing fixed assets or borrowing money in the form of a loan from another business or person can serve as examples of leverage.
