Why is it important to specify both magnitude and direction? To fully describe the object’s velocity, both magnitude (25 m/s) and direction (e.g., south) must be stated. In order for such descriptions of vector quantities to be useful, it is important that everyone agree upon how the direction of an object is described. What is […]
Why do cells form tissues?
Why do cells form tissues? Cells are grouped together to carry out specific functions. A group of cells that work together form a tissue. Your body has four main types of tissues, as do the bodies of other animals. These tissues make up all structures and contents of your body. How do cells specialize? Cell […]
How can the validity of an experiment be improved?
How can the validity of an experiment be improved? You can increase the validity of an experiment by controlling more variables, improving measurement technique, increasing randomization to reduce sample bias, blinding the experiment, and adding control or placebo groups.

Do you need planning permission to install a wind turbine?
Do you need planning permission to install a wind turbine? A wind turbine installed as a stand-alone installation: One turbine is considered permitted development and the property must not have an Air Source Heat Pump installed already. Otherwise you need to ask for planning permission. The highest part of the wind turbine blade must not […]

Why is it important to know protein concentration?
Why is it important to know protein concentration? Determining the protein concentration in your sample is an important step in any laboratory workflow that involves protein extraction and/or analysis. Knowing how much protein you have can help you compare results from one protein to another and from one experiment to the next. How does Beer’s […]

Are transverse waves faster than longitudinal?
Are transverse waves faster than longitudinal? No, longitudinal waves travel faster than transverse waves. The longitudinal wave transmission is faster than transverse wave transmission. This speed difference between the longitudinal and transverse wave can be noticed during an earthquake. What is the difference between transverse and longitudinal waves BBC Bitesize? The direction of these oscillations […]
What is least gravitational potential energy?
What is least gravitational potential energy? When the planet is closest to the Sun, speed v and kinetic energy are the highest, and gravitational potential energy is the lowest. When the planet moves farther away, the speed and kinetic energy decrease, and the gravitational potential energy increases. What is SI unit of gravitational potential? The […]
