he put uranium crystal and photgraphic plate ina drawer
When Becquerel took the items out of the drawer, he observed that the uranium compound had fogged up the photographic plate wrapped with them, indicating that the uranium was emitting radiation capable of penetrating the paper covering the plate. This accidental discovery led to the development of the field of nuclear chemistry.
there was an ominouse spot on his photographic plate that of which was placed next to the plutonium crystal
If the "items" in question were photographic plates, then he noticed that they had been "fogged," which he determined was due to the presence of radioactive materials nearby.
Thomas Edison used a carbonized bamboo filament in his early light bulbs, and later switched to a carbonized cotton thread filament to improve durability and lifespan.
This statement is incorrect. John Dalton was a British scientist known for developing the atomic theory in the early 19th century. The scanning tunneling microscope was invented much later, in 1981 by Gerd Binnig and Heinrich Rohrer.
Acceleration can be found using the equation: acceleration = change in velocity / time taken. To measure acceleration without using force, you can observe the change in velocity of an object over a certain time interval and calculate the acceleration based on this change.
The periscope was invented in 1854 by Hippolyte MariΓ©-Davy, a French inventor. He created it as a way to observe the underwater world from the surface without having to submerge. The design was later improved and adapted for use in submarines as a way for the crew to see above the water while remaining below the surface.
Yes, you can cool down rice quickly by rinsing it with cold water and then storing it in the refrigerator for later use. Make sure to store the rice in an airtight container to maintain freshness. Reheat thoroughly before serving.
no, nuclear decay is a natural phenomena that has existed as long as the universe becquerel discovered it in the 1890s when he left uranium ore samples in a drawer on a stack of unexposed photographic plates and later when they were developed found that the ore had somehow exposed them.
Robert Hook was first to look through a microscope to observe slices of cork. He described these as "boxes", later came to know as "cells".
Becquerel discovered radioactivity by accident while studying a mineral containing uranium. he observed that with exposure to sunlight the mineral gave off a penetrating energy that exposed the film. while one day he tried the experiment one day the day was cloudy so he put it away in a dark desk drawer and at the next day he found the picture of the mineral and later found out that the mineral did not need sunlight to expose radiation so he gave it to two young researchers that eventually isolated the two elements named polonium and radium
Tesla did not make the Flourscent bulb. In 1859 Alexandre E. Becquerel did. Tesla wanted to make use of them and discussed them at length decades later. But he did not discover, or invent them.
yes u can == ==
To be able to study and observe it later and learn more about the past and the creatures in it.
It saves items that you might want later
maybe later
out of the remote control on the table
There is a battery in the toy truck. You can use the screwdriver from the kitchen drawer to take it out and put it in the TV remote. Then you can put it back later to use the truck.
No.
The word later is an adjective. It is the second of two items.
