The research of astronomy during the time period of 1970 - 1990 is given below:
<u>Date</u> <u>Event</u>
1. 15 June 1974 Black Brant VC sounding rocket from White Sands.
2. 14 May 1973 Launch of Skylab, the USA's first space station
3. 26 July 1971 Launch of Apollo 15
<h3>What is Astronomy?</h3>
This refers to the branch of science that deals with celestial bodies and their relation to each other.
Hence, from information about astronomy, between the time period 1970 - 1990 as it was on the 26th of December, 1974 that the Soviet space station Salyut-4 was launched.
The event I think had the greatest impact in astronomical history during this time period was the launch of Apollo 16.

Answer:
The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together. ... When displacement vectors are added, the result is a resultant displacement.
Answer:
Light demonstrates wave-like and particle-like characteristics
Explanation:
Light itself is a wave but under circumstance it will present particle-like charcteristics. This is called wave-particle duality :)

Answer:
- 1.602 x 10⁻¹⁹coulombs
Explanation:
Charge on individual oil droplet would be multiple of charge on one electron . So we will find out the minimum common factor of given individual charges that is the LCM of all the charges given.
LCM of given charges like 3.204 , 4.806 ,8.01 and 14.42 . We have neglected the power of ten( 10⁻¹⁹) because it is already a common factor to all.
The LCM is 1.602 . So charge on electron is 1.602 x 10⁻¹⁹.
