Answer:
¢
Explanation:
Given that:
Mass of metal = 12g = 0.012
Density of metal = 4 g/cm³ = 4000kg/m³
Density of oil = 1.5g/cm³ = 1500 kg/m³
Recall : density = mass / volume
Volume of metal, V = mass / density = 0.012/ 4000 = 0.000003
0.000003
T + Density of oil * g * V - (0.012 * 9.8) = 0
T + 1500 * 9.8 * 0.000003 - 0.1176 = 0
T = 0.0441 - 0.1176 = 0
T = 0.1176 - 0.0441
T = 0.0735N
Tension, T

Answer:
Explanation:
Kinetic energy gained by alpha particle
= charge x potential difference
1/2 mv² = 3.2 x 10⁻¹⁹ x 3.45 x 10⁻³
.5 x 6.68 x 10⁻²⁷ V² = 11.04 x 10⁻²²
V² = 3.3 x 10⁵
V = 5.74 x 100
= 574 m / s

B , C, are unknown .
Answer: B. The distance of the sun
When an object is put into water (or any other liquid) there are forces placed on it. These forces create depth in the liquid and its density will affect the upthrust on an object The same situation will occur no matter how deep the object is placed (as long as it is completely submerged).
