Answer: No crash landing on the surface of the moon and there is no vibration due to low acceleration due to gravity.
Explanation:
The rocket ship can't land on the surface of the moon because it depends on winged flight for its controlled descent to the surface of the Earth. Since the moon has no real atmosphere, the wings would not be able to glide the craft smoothly to the moon's surface.
The acceleration due to gravity in the moon is very low compared to the earth. The astronauts cannot experience vibration ripple through the Moon’s surface beneath their feet because the low level acceleration due to gravity will drastically affect the weight of the ship.
Answer:
The correct option is: d. Fiber-optic
Explanation:
A fiber-optic cables or an optical-fiber cable is a cable that is composed of a bundle of optical fibers. These cables are used for transmitting information or digital signals over long distances.
Each optical fiber in an optical-fiber cable is individually coated with a protective plastic cover and contained in a protective tube. Therefore, an optical-fiber cable is not affected by any electromagnetic interference or radio frequency interference.
Answer:
Part a)
Part b)
Explanation:
Part a)
In order to have same range for same initial speed we can say
so after comparing above we will have
so we have
Part b)
Time of flight for the first ball is given as
Now for other angle of projection time is given as
So here the time lag between two is given as
Answer:
Ice is the solid state of water, a normally liquid substance that freezes to the solid state at temperatures of 0 °C (32 °F) or lower and expands to the gaseous state at temperatures of 100 °C (212 °F) or higher.
