The correct answer of the given question above about the relationship between a line and a point in a plane is the second option. The statement that best describes the relationship between a line and a point in a plane […]

What is the use of polymer? Uses of polymers Polymer Properties Uses Poly(chloroethene) ‘PVC’ Tough, electrical insulator, can be made hard or flexible Insulation for electrical wires, windows, gutters, pipes Poly(tetrafluoroethene) ‘PFTE’ Slippery, chemically unreactive Non-stick coatings for pans, containers for laboratory substances Is as plastic safe? ABS, AS/SAN plastics So what about ABS, AS […]

Is kinetic energy proportional to temperature? The physical behaviour of gases is explained by the kinetic molecular theory of gases. The number of collisions that gas particles make with the walls of their container and the force at which they collide determine the magnitude of the gas pressure. Temperature is proportional to average kinetic energy. […]

Under what condition torque on current loop is zero? (c) Zero (minimum) torque occurs when θ is zero and sin θ = 0. (d) The torque reverses once the loop rotates past θ = 0. τ=wIlBsinθ τ = w I l B sin ⁡ . Does the torque on a planar current loop? Hence torque […]

What are the four strokes of an engine in the correct order? An internal-combustion engine goes through four strokes: intake, compression, combustion (power), and exhaust. Where is the piston on the compression stroke? The piston starts at Top Dead Center (TDC). As it travels down the cylinder, the intake valve opens. The air/fuel mixture is […]

What is the best source of clean energy? Hydropower What are the new sources of energy? New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) account for another 3% and are growing very rapidly. The share of renewables in electricity generation is around 19%, with 16% of global electricity coming from hydroelectricity, and […]

What is the number 42 in numerology? The numerology number 42 is a nurturing number primarily focused on individuals, family, and community. The number resonates with a pragmatic approach for assisting individuals and relationships to what 42 decides is ideal. The energy the number 42 represents is idealistic, but also pragmatic. Is 41 a lucky […]

What is the relationship between power and distance? Distance is described in units of meters and velocity is described in units of meters per second. So the difference between distance and velocity is that velocity is divided by time. With power and energy, power is units of energy divided by time. The same difference as […]

What is used to hold and heat liquids? Beakers. Beakers come in different sizes and are usually cylindrical with a spout for pouring liquids. They are specifically used to hold, mix, stir and heat liquids. What holds 100ml water? A 100 ml volumetric flask is designed to hold exactly 100 ml, but if the liquid […]

How do you write a good hypothesis? However, there are some important things to consider when building a compelling hypothesis. State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment. Try to write the hypothesis as an if-then statement. Define the […]
