5) The gravitational force between two objects that are 2.1x10 * m apart is 3.2x10*° N. If the mass of one object is 55 kg what is the mass of the other object?
Answer (2)
Answer:1. As you vary the angle between two mirrors, the number of images formed changes. Specifically, as the angle decreases, the number of images increases, and as the angle increases, the number of images decreases.2. The relationship between the number of images formed and the angle between two mirrors can be expressed mathematically. The formula for the number of images (N) formed by two mirrors is given by:N = (360° / θ) - 1where θ is the angle between the mirrors in degrees. This formula shows that the number of images increases as the angle decreases.3. To derive the formula for determining the number of images formed by two mirrors, consider the following:When the angle between the mirrors is θ, the full circle is 360°.Each time the angle is divided into the circle, it creates an additional image. The formula can be understood as dividing 360° by the angle between the mirrors (θ) to find how many reflections fit into a full circle.Subtracting 1 accounts for the original object itself, resulting in:N = (360° / θ) - 14. To achieve an infinite number of images, the mirrors should be arranged at an angle of 0°, meaning they are parallel to each other. In this arrangement, light reflects back and forth between the two mirrors indefinitely, producing an infinite number of images.
F = G * (m₁ * m₂) / r², whereF = 3.2 × 10⁰ N,m₁ = 55 kg,r = 2.1 × 10⁰ m,G = 6.67 × 10⁻¹¹ N·m²/kg².
