Question

URGENT DAU 100 PUNCTE

Answer 1

l

1. camp de atractie

2. greutate

3. fizica, de sus in jos pe verticala

4. masa

5. intens , slab

6. gamma = F/m

ll.

1.

gamma0 = KxMp/r1^2

gamma1 = KxMp/r2^2

gamma1 = gamma0/36

=> KxMp/r1^2 =  (KxMp/r2^2) x 1/36

=> KxMpxr2^2x36 = KxMpxr1^2

=> 36r2^2 = r1^2

=> la o distanta de 36ori mai mare fata de punctul de referinta

2.

raza Lunii = 1730 km, 7,34×10^22 kg adica 0,012300 din a Pământului

raza Pamantului = 6371 km, masa = 5,97×10^24 kg

Fg.L = KxM.L/R.L² = Kx0,0123xMP/1730² = 2,45x10^16

Fg.P = KxM.P/R.P² = KxM.P/6371² = 1,47x10^17

=> Fg.L / Fg.P = 2,45x10^16 / 1,47x10^17 = 0,167
