Geomagnetic storms could impact power grids, blacking out entire cities, disconnecting radio communications and GPS navigation. Hope this helped! :)
Answer:
The answer is in the picture attached
Explanation:
A six-membered aromatic ring is one of the most common structures in natural compounds.
The aldehyde group in position one consist in one carbon double-bonded to oxygen and bonded to hydrogen.
The alkoxy group in position three consist in a oxygen bonded to an alkyl group (The simplest alkyl group is methyl -CH₃-).
There is, in position four, an hydroxyl group -OH. bonded to this six-membered aromatic ring.
I hope it helps!
Answer:
240 seconds
Explanation:
Data Given:
Distance Radio travel to earth = 7.19 ×10⁷ km
Speed of this radio signal = 3.00 ×10⁸ m/s
Solution:
First convert Km to m
1 km = 1000 m
7.19 ×10⁷ km = 7.19 ×10⁷ x 1000 = 7.19 × 10¹⁰m
Formula used to calculate time
Speed (S) = distance (d) / time (t)
rearrange above equation for time
time (t) = distance (d) / Speed (S) . . . . . . . . .(1)
Put values in equation 1
time (t) = 7.19 × 10¹⁰/ 3.00 ×10⁸ m/s
time (t) = 240 s
So 240 seconds it take for the signal to reach the earth
Answer:
E) Br Br
Explanation:
Covalent bond -
Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
A covalent bond to be non polar in nature , then the atoms need to have almost similar electronegativity , so that they won't split into partial negative and partial positive charge .
Hence , from the given options of the question ,
E) Br Br , both the atoms are same , hence same electronegativity , therefore are non - polar in nature .
Answer:
it depends on the medium and the temperature
