Answer:
The correct answer is letter b. less than
Explanation:
In the attached schematic figure, the lens (lens) is initially adjusted for a given distance from the object. If the object gets closer, the image loses its sharpness. To recover it, the lens settles down, increasing convergence, that is, decreasing the focal length.
Answer:
Explanation:
Astronauts face a wide range of dangers when maneuvering in space. Collecting rock samples requires breaking apart rocks on the moon's surface, which requires tools. These tools are sometimes small hammers or other times special drills. All of this process means moving and using force to break these rocks apart and every single movement can cause a mistake which can lead to a piece of the suit ripping or a failure in the machinery. Since there is no oxygen on the moon the tiniest failure in the suit can lead to the death of the astronaut. Therefore, having backup safety precautions, and quick repair scenarios is a must when collecting rock samples on the moon.
Explanation:
Let us assume that the separation of plate be equal to d and the area of plates is 
. As the capacitance of capacitor is given as follows.
C = 
It is known that the dielectric strength of air is as follows.
E = 
Expression for maximum potential difference is that the capacitor can with stand is as follows.
dV = E × d
And, maximum charge that can be placed on the capacitor is as follows.
Q = CV
= 
= 
= 
= 
or, = 10.62 nC
Thus, we can conclude that charge on capacitor is 10.62 nC.
Answer:
The presence of strong intermolecular forces favors a condensed state of matter. liquid or solid), while very weak intermolecular interaction favor the gaseous state.
The answer is true. Distraction “latency” lasts for about 27 seconds.
This means that even after driver put down the phone or stop fooling with the navigation system; he or she isn’t fully committed with the driving task. Talking on a cell phone and texting are frequent what people associate with distracted driving, but there are so much more activities behind distracted driving.
