The 2019 XC60 is the safest midsize luxury SUV, having been awarded a 2019 IIHS Top Safety Pick. Has […]

What causes viscosity? Viscosity is caused by friction within a fluid. It is the result of intermolecular forces between particles within a fluid. What is viscosity and its causes? Causes of Viscosity Due to strong cohesive forces between the molecules, any layer in a moving fluid tries to drag the adjacent layer to move with […]

Does cool air push warm air upward? This type of front is called a warm front. It generates nimbostratus clouds, which can result in moderate rain. On the other hand, when a cold air mass catches up with a warm air mass, the cold air slides under the warm air and pushes it upward. What […]

How do you find the primary and secondary windings of a transformer? The primary winding is the coil that draws power from the source. The secondary winding is the coil that delivers the energy at the transformed or changed voltage to the load. Usually, these two coils are subdivided into several coils in order to […]

What are the disadvantages of carbon nanotubes? One of the main disadvantages of carbon nanotubes is the lack of solubility in aqueous media, and to overcome this problem, scientists have been modifying the surface of CNTs, i.e., fictionalization with different hydrophilic molecules and chemistries that improve the water solubility and biocompatibility of CNT [67]. Is […]

Which classification group has the most similarities? The correct answer will be- species. Explanation: The hierarchical system of classification was proposed by the Carolus Linnaeus in the 18th century which categorized the organism into seven groups from the kingdom as the most inclusive group followed by the phylum, division, class, order, family, genus and species.

What is work measured in? work done (W) is measured in joules (J) force (F) is measured in newtons (N) distance (d) is in the same direction as the force and is measured in metres (m) What is a force unit? Newton How do you find the length of the space curve? Arc Length Along […]

What instrument is the rover carrying? It carries seven primary payload instruments, 19 cameras, and two microphones. The rover also carried the mini-helicopter Ingenuity to Mars, an experimental aircraft and technology showcase that made the first powered flight on another planet on April 19, 2021. What technologies does NASA use to explore Mars? Like NASA’s […]
