What is the critical approach to technology? Drawing inspiration from Marx’s approach, critical theory of technology argues that technology is both rational and biased. The design, development and eventual implementation of a technology are seen as normative processes through which interests and values are delegated to technological devices and systems. Does technology determine society? Technological […]

Does higher volume mean higher density? Density is determined by an object’s mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density. It is about how heavy something is compared to the same amount (volume) of water. Are volume and mass […]

How are metamorphic rocks classified? Metamorphic rocks are broadly classified as foliated or non-foliated. Non-foliated metamorphic rocks do not have aligned mineral crystals. Non-foliated rocks form when pressure is uniform, or near the surface where pressure is very low. The other minerals have been crushed and deformed into a fine-grained matrix (Mtx). What are metamorphic […]

What is better a generator or inverter? Conventional portable generators are able to produce more power than inverter generators. This has to do with a number of factors including the size of the fuel tank and the mechanical difference in electricity production. Inverter generators are more energy efficient thanks to how the final AC current […]

How development is both qualitative and quantitative? Development is the combination of qualitative and quantitative process of growing or causing something to grow or become larger or more advanced. The term ‘growth’ and ‘development’ are not new but refer to changes over a period of time. Is Child Development continuous or discontinuous? Continuous development sees […]

What is the lifespan of a neutron star? 1 million years Can you touch a neutron star? So when anything tries to touch neutron star, it would be suck in by gravity and collapse into lump of neutrons and feed their mass into that neutron star. And if it collects enough mass it would collapse […]

What are the examples of force change in size? A force can change the shape and size of an object If we take a spring and pull it at both the ends with our hands ,then the shape and size of the spring changes, the force of our hands changes the shape and size of […]

Why would a researcher interested in making a casual claim not do an experiment? Why would a researcher interested in making a causal claim NOT do an experiment? There may be ethical limitations of manipulating a variable. Why is the statistical validity of a multiple regression design more complicated to interrogate than a bivariate design? […]
