What is the standard form of 12000000000? The standard form is: 1.2 * 10^10. What is the exponential form of 648? Answer. ANS: 2×2×2×3×3×3×3 =2^3 × 3^4… How the distance to stars is measured? To measure the distance of a star, astronomers use a baseline of 1 astronomical unit (AU), which is the average distance […]
Which mineral properties can you identify without special tools?
Which mineral properties can you identify without special tools? In working with hand samples without specialized tools, mineral hardness is specified by the Mohs hardness scale. The Mohs hardness scale is based 10 reference minerals, from talc the softest (Mohs hardness of 1), to diamond the hardest (Mohs hardness of 10). It is a relative, […]
How do you calculate channel capacity when SNR is present?
How do you calculate channel capacity when SNR is present? Hence, the channel capacity is directly proportional to the power of the signal, as SNR = (Power of signal) / (power of noise). so for example a signal-to-noise ratio of 1000 is commonly expressed as: 10 * log10(1000) = 30 dB. What is channel capacity? […]
Why is crystallization done class 11?
Why is crystallization done class 11? Crystallisation of the filtrate This is done to ensure uniform evaporation and to prevent formation of a solid crust. When the volume of the solution is reduced to one half, dip one end of a glass rod in the concentrated solution and cool the drop by blowing on it. […]
What are the 3 definitions of health?
What are the 3 definitions of health? Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Why do we need models of health? model increases understanding of the relationship between stressors, coping and health. Why should we consider the wider determinants of health? As […]

Should you explain in classical mechanics a moving body with constant speed has no force?
Should you explain in classical mechanics a moving body with constant speed has no force? From classical mechanics, we know that the force is the rate of change of momentum, one of it’s simplest forms is F=ma, so if a body moves with constant velocity, then its acceleration is zero, and by the previous definition […]
What causes change to ecosystems?
What causes change to ecosystems? Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3). Do ecosystems change little over time? Ecosystems, the interactive system of living […]
How do you keep a water bath at constant temperature?
Why is a Spherometer called so?
Why is a Spherometer called so? A spherometer basically is a precision instrument to measure very small lengths. Its name reflects the way it is used to measure the radii of curvature of spherical surfaces. Where is Spherometer used? The Spherometer is a device use in measuring the radius of curvature of a spherical surface. […]
