Answer:
3.44:1
Explanation:
We use ratios to find the ratio of weight.
Mass of Plane= 110000 kg ∴ W= mg
Mass of Boat =31999 kg
=
=
SO 3.44:1
The answer is is 730.5 days rounded, so A. 730
Venus goes through phases similar to those of earths moon.
Answer:
q = 4.04×10^-12C
n = 2.53×10^7
Explanation:
1. Electrostatic force on charge due to electrical field E is F = qE
Gravitational force due to weight of drop of mass M is F = mg, when net force is zero we have to find the charges on the drop.
2. Charge on drop: since gravitational force is acting downward, electric field is acting upward and we equate both equations.
Therefore, Fg = Fe
qe = mg
q = mg/E
q = 3.50×10^-9kg×9.8m/s²/8480N/c
q = 4.04 × 10^-12
3. Number of protons by quantitization law
n = q/e
n = 4.04× 10^-12/8480
n = 2.53× 10^7
Answer:
Explanation:
Applying conservation of momentum
mA v0 + 0 = mA x 12v0 + mB x 92v0
11 mA = - 92mB .
mA / mB = 92 / 11
mA : mB = 92 : 11.
