What rocks is coarse grained? Coarse grain varieties (with mineral grains large enough to see without a magnifying glass) are called phaneritic. Granite and gabbro are examples of phaneritic igneous rocks. Fine grained rocks, where the individual grains are too small to see, are called aphanitic. Basalt is an example. What are the most common […]

What is ∈ called? The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A. Which are the real […]

What is the largest type of tephra? All explosive volcanic eruptions generate tephra, fragments of rock that are produced when magma or or rock is explosively ejected. The largest fragments, blocks and bombs (>64 mm, 2.5 inches diameter), can be expelled with great force but are deposited near the eruptive vent. How do you protect […]

What happen if the ball hit directly on the endline? What happens if the ball hits directly on the endline? The ball may only be contacted 2 times before returning over the net. What is the maximum number of times one person can hit the ball in a row? three What is the maximum hits […]

It includes the SAE viscosity grade of the oil, API standards met by the oil, and other important performance parameters. Can I mix synthetic and regular oil? yes. If you don’t have a […]

How long can I dive at 60 feet? The old guideline for safe ascent was 60 feet per minute, which has been revised down to to the current recommendation of 30fpm. The rate of ascent is more critical at shallower depths, so many might ascend faster at deeper depths and slow to 30fpm or less […]

What 3 things does thermal energy depend on? The thermal energy of an object depends on three things: 4 the number of molecules in the object 4 the temperature of the object (average molecular motion) 4 the arrangement of the object’s molecules (states of matter). The more molecules an object has at a given temperature, […]

Why do we use standard unit? To make our judgement more reliable and precise, we need a common unit of measurement. The calculation for proper support should be the same in case of everyone. Thus, measurement uniformity should be present. We need a popular set of measuring units, which are called regular units, just for […]

What are 3 characteristics of microwaves? Following are the main properties of Microwaves. Microwaves are the waves that radiate electromagnetic energy with shorter wavelength. Microwaves are not reflected by Ionosphere. Microwaves travel in a straight line and are reflected by the conducting surfaces. Microwaves are easily attenuated within shorter distances. Why Microwaves are used in […]
