Question

1 kgm^2s^-2 = ______ gcn^2s^-2​

Answer 1

Answer:

ANSWER

(a)

1 kgm 2 /s 2

=1000gm×(100cm) 2 /s 2

=10 7 gcm 2 /s 2

(b)

1 ly=(365×24×3600)s×(3×10 8 )m/s

1 ly=9460730472580800 metres(exactly)

1 m=10 −16 ly

(c)

3 m/s 2

=3×(10 −3km)×(1/3600h) −2

=3×3600 2 ×10 −3 kmh −2

=38880 kmh −2

(d)

G=6.67×10 −11 Nm 2 kg −2

=6.67×10 −11 kgm/s 2 m 2 kg −2

=6.67×10 −11 s −2 m 3 kg −1

=6.67×10 −11 s −2 ×(100cm) 3 /1000g

=6.67×10 −11 s −2 ×10 6 cm 3 /1000g

=6.67×10 −8 s −2 cm 3 g −1
