When a compact disc (CD) is viewed in sunlight, the colors similar to those of a rainbow are seen due to the phenomena of reflection and diffraction. The CD’s surface consists of closely spaced tracks that act as a diffraction ...
The temperature of an object indicates that on contact, heat will flow from that object to an object at a higher temperature. Heat naturally transfers from regions of higher temperature to regions of lower temperature until thermal equilibrium is reached.
To reduce angular speed on a freely rotating platform, a person should spread their hands outwards. This increases the moment of inertia, causing the rotational speed to decrease according to the conservation of angular momentum.
The force of Earth’s gravity acting on a body of mass 1 kg is calculated using the formula F = m x g, where g is the acceleration due to gravity (9.8 m/s²). Therefore, the force is 1 kg x ...
