The force by which earth attracts anobject is know as weight of that particular object.

so,

=》weight ( F ) = mass ( M ) × acceleration ( A )

=》F = 85 × 9.8

( because acceleration due to gravity = 9.8, but sometimes it is taken as approx 10 )

=》F = 833 Newton.

note : if you take acceleration due to gravity as 10 then the weight of the person = 85 × 10 = 850 N )

i hope it helped.....

Answer:

-30°C

Explanation:

F-32/180 =C-0/100

or, -22-32/180=C/100

or, -54/180*100=C

or, -0.3*100=C

therefore, C= -30

-22°F = -30°C

A car travel with a constant velocity of 20.5m/s for 20seconds what distance does it cover in this time ?

prohojiy [21]

Answer:

410 m

Explanation:

Given:

v₀ = 20.5 m/s

a = 0 m/s²

t = 20 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (20.5 m/s) (20 s) + ½ (0 m/s²) (20 s)²

Δx = 410 m
