The Space Race
The wonderful space race, beginning in 1955 and lasting until 1975 was a competition between the United States and the Soviet Union where they were trying to achieve superiority in spaceflight. The competition between the U.S and the Soviet Union began in 1955 when the U.S announced their intention to launch artificial satellites, and four days later the Soviet Union announced that they would also be launching a satellite(s) “in the near future”
In October 1957 the USSR achieved the first successful satellite launch, as well as in April 1961 sent the first human into orbit beating the U.S in first human into orbit which took place in May 1961. Shortly after the U.Ss first human launch, John F. Kennedy proceeded to raise the stakes and asked the U.S Congress to commit to the goal of landing a man on the moon and returning him safely. Both the U.S and the Soviet Union then proceeded to develop super heavy lift launch vehicles, and later in July of 1969 Apollo 11 proceeded to launch and land man on the moon, the USSR pursued two crewed lunar programs but failed to beat the U.S in first man on the moon, and later began to concentrate on Salyut which was the first space station program.

Answer:
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.Of the four natural forces, known as the strong, weak, gravity and electromagnetic forces, the aptly named strong force dominates over the other three and has the job of holding the atomic nucleus together.
Answer:
<u>- ied:</u> cry, enjoy, bury, marry
<u>-ed only</u>: label, wait, stay, explain, fail, prefer
<u>- d only:</u> care, like, agree, use
<u>double consonant +- ed
</u>: stop, jog, clap, hop
Explanation:
We form regular Past Simple verb forms by adding the termination <em>-ed </em>to the infinitive of the verb.
e.g. wait, stay, explain
However, there are some exceptions, as the result of the spelling rules.
If the verb ends in <em>-e</em>, we will add the termination <em>-d</em>:
e.g. care, like, use
If the verb ends in a vowel and a consonant, we double the consonant before <em>-ed</em>:
eg. stop, clap, hop
If the verb ends in consonant and <em>-y</em>, we take off the y and add <em>-ied</em>.
e.g. cry, enjoy, marry
