Why do I look different in the mirror than in photos? This is because the reflection you see every day in the mirror is the one you perceive to be original and hence a better-looking version of yourself. So, when you look at a photo of yourself, your face seems to be the wrong way […]
How many GB is a 1000 photos?
What causes dispersion?
What causes dispersion? Dispersion occurs due to the different degrees of refraction experienced by different colours of light. Light of different colours may travel with the same speed in a vacuum, but they travel at different speeds in some refracting medium. The speed of violet light is relatively lower than that of red light. Why […]
What two factors determine the strength of the force of gravity between two objects?
What two factors determine the strength of the force of gravity between two objects? Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them. Objects that […]
What does the Boltzmann equation describe?
What does the Boltzmann equation describe? 1 The Boltzmann equation. The Boltzmann equation describes the evolution of the particle density of a rarefied gas. Indeed, the molecules of a gas can be modeled by hard spheres that move according to the laws of classical mechanics. How is Boltzmann ratio calculated? P = 1/Z * exp(- […]
What has size shape but no weight?
What has size shape but no weight? Anything in zero-gravity can have a certain size, shape but will be weightless. Explanation: The weight of a person or an object is actually a force. What takes the size and shape of any container? A liquid takes a shape of the container because particles in a liquid […]
How is energy classified?
How is energy classified? Energy can be classified as either stored (potential) energy and working (kinetic) energy. All energy can be measured in “Joules”. Potential Energy = the energy that an object has as the result of its position or state. Thermal Energy = the total energy of the particles that make up a mass. […]
What is the relationship between luminosity and magnitude?
What is the relationship between luminosity and magnitude? Relationship to magnitude Luminosity is an intrinsic measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing flux of light as a result of distance according to the inverse-square law. […]

The braking distance of a vehicle can be affected by: poor road and weather […]
What are 5 reasons physical education is important?
What are 5 reasons physical education is important? Here are five reasons why physical education is an essential part of a well-rounded education: It Encourages Healthy Habits. First let’s state the obvious: kids who get daily exercise are healthier. It Reduces Stress. It Encourages Prosocial Behavior. It Promotes Good Sleep. It Helps Students Concentrate. Why […]
