A triangle is just a shape...
Answer:
4.3 L
Explanation:
Ideal gas law:
PV = nRT
Rearrange:
V / T = nR / P
Since n, R, and P are constant:
V₁ / T₁ = V₂ / T₂
Plug in values and solve:
(3.5 L) / (25 + 273.15 K) = V / (95 + 273.15 K)
V = 4.3 L
Answer:
The angle from the normal is 15.1°.
Explanation:
We can find the angle by using Snell's law:
Where:
n₁: is the first medium (glass) = 1.5
n₂: is the second medium (air) = 1.0
θ₁: is the first angle (in the glass) = 10°
θ₂: is the second angle (in the air) =?
Therefore, the angle from the normal is 15.1°.

Answer:
3.036×10⁻¹⁰ N
Explanation:
From newton's law of universal gravitation,
F = Gm1m2/r² .............................. Equation 1
Where F = Gravitational force between the balls, m1 = mass of the first ball, m2 = mass of the second ball, r = distance between their centers.
G = gravitational constant
Given: m1 = 7.9 kg, m2 = 6.1 kg, r = 2.0 m, G = 6.67×10⁻¹¹ Nm²/C²
Substituting into equation 1
F = 6.67×10⁻¹¹×7.9×6.1/2²
F = 321.427×10⁻¹¹/4
F = 30.36×10⁻¹¹
F = 3.036×10⁻¹⁰ N
Hence the force between the balls = 3.036×10⁻¹⁰ N
