How do you describe a distance time graph? If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the […]
How do you protect springs?
How do you protect springs? Protection principles 1. Protect the catchment area above the spring from animals and humans to prevent contamination. 2. Constructing a cut off drain above the spring prevents contaminated water from entering or mixing with the spring water. Why does Florida have so many springs? Florida has an abundance of springs […]
What is unusable energy called?
What is unusable energy called? In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as the energy transferred from one system to another that is not doing work. Entropy is a measure of randomness or […]
What is a non example of physical property?
What is a non example of physical property? examples: mass, density, color, boiling point, temperature, and volume. non examples- anything that’s NOT a physical property will be a non-example. emotion is not a physical property. form of matter that flows, has a fixed volume, and takes the shape of its container. What are examples of […]
Why is transpiration an important process in a plant?
Why is transpiration an important process in a plant? It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis. Plants need to cool themselves for several reasons. Transpiration is an evaporative cooling system that brings down the temperature of plants, but since it leads to water loss, […]
How do you know what angle to cut?
Why do some object float and others sink?
Why do some object float and others sink? Why do some things float and other things sink? It depends on the density of the object. Density is a measure of both how massive those molecules are, and how closely packed together they are. If the object’s total density is greater than that of water, it […]
What is D-block in jail?
What is D-block in jail? D-Block housed the worst inmates and five cells at the end of it were designated as “The Hole”, where badly behaving prisoners would be sent for periods of punishment, often brutally so. How do I learn d-block elements? D-block elements it includes are Lutetium (Lu), Hafnium (Hf), Tantalum (Ta), Tungsten […]
What affects period of a spring?
What affects period of a spring? The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant. What is the formula for oscillation? The period formula, T = 2π√m/k, gives the exact relation between the oscillation time T and the […]
