Answer: D
Explanation:
Insolation means incoming solar radiation. It is the amount of incoming solar radiation that is received per unit area of the earth’s surface.
At any point except D, insolation is lesser because sun radiation is more spread out and as a result less solar radiation is received per unit area of the earth’s surface.
So, choice D is the correct answer.
Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid and is given by,
Where,
m = mass of the falling object.
g = the acceleration due to gravity.
\rho = the density of the fluid the object is falling through.
A = the projected area of the object.
C = the drag coefficient.
A) Because a drop is difficult to approximate to a certain form, it usually tends to be considered a spectrum, the terminal velocity for a sphere is given by
Whatever our appreciations, all the variables are constant, except for the Diameter, we can realize that the terminal velocity is proportional to the radius of the object, the greater the radius - the larger the drop - the greater the terminal velocity.
B) Since there is a "constant" terminal velocity at the end of the path, at which point the forces are balanced, the acceleration will be 0. For both objects.
<span>Option C. The sodium vapor lamp is a gas discharge lamp that uses sodium vapor for the production of light. It is an efficient lighting source that provides lumens per watt and produces bright yellow. It has a monochromatic light that makes its applications are reduced. It is used in street lighting, streets, highways, etc.</span>
Answer:
A. Yes, when another driver makes a mistake, you will have time to react
Explanation:
Yes it is good to make space cushion between two cars because due to some urgency when front vehicle applied brakes then the driver of the rear car will definitely take some time to react.
This reaction time may be between 0.5 s to 0.8 s for different people
so the rear car will move with same speed for above reaction time and it will cover the cushion distance between two cars
If we will not maintain this cushion distance between two cars then we can see that the two cars will collide and that may cause many accidents
so it is correct statement and correct option would be
A. Yes, when another driver makes a mistake, you will have time to react
Crushing particles of solute. The more surface area of the solute exposed to the solvent the faster the solute will dissolve and react with the solvent
