Answer:
We cannot tell from the information given
Explanation:
Given;
mass of the box, m = 5 kg
first force, F₁ = 10 N
second force, F₂ = 5 N
(I) Assuming the two forces are acting horizontally in opposite direction, the resultant force on the box is calculated as;
∑Fx = 10 N - 5 N
= 5 N
Apply Newton's second law of motion;
∑Fx = ma
a = ∑Fx/m
a = 5 / 5
a = 1 m/s² in the direction of the 10 N force.
(II) Also, if the two forces are acting in the same direction, the resultant force is calculated as;
∑Fx = 10 N + 5 N
∑Fx = 15 N
a = 15 / 5
a = 3 m/s²
Therefore, the information given is not enough to determine the acceleration of the box.

Ratio of resistances of two bulbs = 2:3
Both are connected in series.
We have to find the ratio of powers in the bulbs..
We know that, current flow through each conductor in series connection remains same. So, we have to use that formula of power which shows relation between current and resistance.
For series connection; P ∝ R
→ P₁/P₂ = R₁/R₂
→ P₁/P₂ = 2/3
→ P₁ : P₂ = 2 : 3
<em>m = 4.3 kg</em>
<em>Hi there ! </em>
<em>use formula</em>
<em>G = m×g => m = G/g</em>
<em>g ≈ 10N/kg</em>
<em>replace G ; g</em>
<em>m = 43N/(10N/kg)</em>
<em>m = 4.3 kg</em>
<em>Good luck !</em>
