A meter scale is placed along the axis of convex mirror of focal length 25 cm, its nearer end being at a distance of 50 cm. Calc
GenaCL600 [577]

Answer:

50 cm

Explanation:

Given that

Focal length of the mirror, f = 25 cm

Distance of the image, u = ?

Distance of the object, v = 50 cm

The formula for the focal length of a convex mirror is given by the relation

1/f = 1/u + 1/v,

where each of the parameters are exactly the same as what I've defined above. So now, if we plug in the values, we have

1/25 = 1/u + 1/50

1/u = 1/25 - 1/50

1/u = (2 - 1)/50

1/u = 1/50

u = 50 cm

So then, we can conclude that the size of the image is 50 cm

Řasy obsahující barvivo se nazývají
soldi70 [24.7K]

Explanation:

Zelené řasy (Chlorophyta v širším smyslu)[pozn 1] je významné oddělení jednobuněčných i mnohobuněčných stélkatých zelených rostlin. Představují blízké příbuzné vyšších rostlin, které se z jedné linie zelených řas vyvinuly. Pokud vyšší rostliny do zelených řas neřadíme, pak jsou zelené řasy nepřirozenou, tzv. parafyletickou skupinou.[1][2] Proto se v novějších systémech do taxonu zařazují i vyšší rostliny[3] a nový smysl (= zelené rostliny) se odráží i v pozměněných názvech – Chlorobionta nebo Viridiplantae. Tento článek však pracuje s tradiční parafyletickou variantou. V tomto smyslu je známo 500 rodů a 16 000 druhů zelených řas.[4]
