What is the meaning of angle of incidence and angle of reflection? At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the […]
Why we can say Internet is the best example of technological convergence?
Why we can say Internet is the best example of technological convergence? Answer Expert Verified internet is the best example of technological convergence because it is being used for online scholing. Also,few years back radio, television, print media, videos, pictures, etc were used as separate machines but now we have them at one place that […]
What is the force acting on the ball?
What is the force acting on the ball? The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion. What is the action force acting on? […]
What rate is the length of the shadow changing?
What rate is the length of the shadow changing? We’ve determined the instantaneous rate of change in the position of the shadow, which is -160 ft/sec, but that figure changes dramatically as the bird moves closer to the ground (and the mouse). In which case the length of the shadow of the tree will be […]
Is it possible to see radio waves?
Is it possible to see radio waves? The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes. Why do pulsars spin so fast? […]

What happens if we use white light instead of laser?
What happens if we use white light instead of laser? Answer White light consists of waves of innumerable wavelengths ranging from violet to red color. So if monochromatic light in Young’s double-slit experiment is replaced by white light, then the waves of every wavelength form their separate interference patterns. Which type of light source is […]
Is calcium smaller than magnesium?
Is calcium smaller than magnesium? However, a magnesium ion has a smaller radius than a calcium ion. This means that a magnesium ion polarises a carbonate ion more than a calcium ion does. Therefore, magnesium carbonate is easier to decompose than calcium carbonate and does so at a lower temperature. Why is magnesium ion smaller […]
What will JB Weld not stick to?
What will JB Weld not stick to? When fully cured, J-B Weld is completely resistant to water, gasoline, and about every other petroleum product or automotive chemical. For wet-surface or submerged water or gasoline repairs, try our SteelStik or WaterWeld. How long will JB Weld last? CURE AND SET TIME: After mixing the tubes at […]
What is spatial polarization?
What is spatial polarization? The polarization process is likely to deepen urban socio-spatial divisions in two ways: the proportions of low- and high-income neighbourhoods can increase in the poorer and better-off parts of the city, respectively. Also, the social distance between these two parts, in absolute terms, can become more extreme. Do you think globalization […]
