Is sea water more dense than water? Salt water is more dense than fresh water Seawater is more dense than fresh water so it sinks beneath freshwater. This means that when rivers flow out into the sea the river freshwater floats on top of the sea water. Is salt water more dense then fresh water? […]

How do I stop talking in my head?
How do I stop talking in my head? Try doing some meditation or yoga to declutter your thoughts. Meditation and yoga can help you be more mindful and quiet out-of-control thoughts in your head. Try doing 15-30 minutes of meditation or yoga whenever your self-talk is bothering you. Do dyslexic people have a voice in […]
What are three things that affect longshore currents?
What are three things that affect longshore currents? When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. Conversely, a wider breaking angle, gentler beach slope, and lower wave height slows a longshore current’s velocity. What causes long […]
Is NaCl a covalent compound?
Is NaCl a covalent compound? For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals….Table 2.11. Property Ionic Covalent Melting temperature High Low Is CaCl2 a covalent compound? CaCl2 or Calcium […]
What are the uses of CCD?
What are the uses of CCD? CCDs are used in optical microscopes because they can possess over 10 million pixels, which enables many samples to be seen clearly, as well as a low noise ratio, ability to image in color, high sensitivity and a high spatial resolution which all contribute to the high-quality images that […]
What factors affect color?
What factors affect color? Factors Affecting How We See Color Lighting: Light plays a HUGE role in color perception. Age: As we get older, our perception of color starts to fade. Poor Color Memory: Human color memory is horrible! Retinal Fatigue: Our eyes get tired very easily. What Colour paint makes a room look bigger? […]
What is Brownian motion explain with diagram?
What is Brownian motion explain with diagram? The zigzag movement of the small particles suspended in a liquid or gas is called brownian motion. The best evidence for the existence and movement of particles in liquid was given by ROBERT BROWN. On looking through the microscope, it was found that the pollen grains were moving […]
What is trajectory generation?
What is trajectory generation? • Trajectory Generation: Construct a trajectory (path + time scaling) so that. the robot reaches a sequence of points in a given time. • Trajectory should be sufficiently smooth and respect limits on joint variables, velocities, accelerations, or torques. What are the disadvantages of the joint space trajectory generation? The drawback […]
What will happen if magnetic field reverses?
What will happen if magnetic field reverses? During an excursion or a reversal, the magnetic field is considerably weakened and allows many more cosmic rays to reach the surface of the planet. These energetic particles from space can be damaging to life on Earth if too many reach the surface. Is the magnetic field stable? […]
