sarita has power of 480 watt. cslculate the amount of mass lifted by her up to 10 meters in 10 seconds. from class 7​

480N

Step-by-step explanation:

Given data

Power= 480watt

Distance= 10meters

Time= 10 seconds

We know that work is power X time

Work= Power * time

But work= force * distance

Force* 10= 480*10

Force= 480*10/10

Force= 480N

Hence the mass is 480N

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
