Answer: Option (A) is the correct answer.
Explanation:
It is known that metals are malleable and ductile. Whereas non-metals are neither malleable nor ductile.
On the other hand, metalloids are the elements which contain properties similar to both metals and non-metals.
Therefore, if a material is ductile, it is most likely a metalloid because it is not necessary that ductility is a property shown by metals only.
Wherease like non-metals, noble gases are also neither malleable nor ductile.
A. Metalloid this is your answer plz click brainly-ist
b. compounds
c. homogeneous mixtures
d. colloids
Answer:
Q = I t = 5.00E-8 C/s * 5.0 s = 2.5E-7 C total charge due to 50 μC for 5 sec
6.242E18 electrons / C * 2.5E-7 C = 1.6E12 electrons
Answer: Microwaves
Explanation:
RADAR stands for radio detection and ranging. Radio waves range from 300 GHz to 30 Hz. Modern radar uses higher frequency of waves for detection. These waves are microwaves (300 MHz-300 GHz). Microwaves are types of radio waves and are used in the radar detection.
The electromagnetic wave which has highest frequency is gamma wave but it is not used for radar detection.
Hence, the correct answer is microwaves are the type pf radio waves which have the highest frequency and are used in radar detection.
