Read the sentence. telescopes or satellites _____ that neither mercury nor venus _____ a moon. which pair of verb forms correctl
vredina [299]

When there is or in-between two words, the tense is dependent upon the word that comes after or. In other words, the word that is closest to the verb will decide the form of the verb.

Since satellites is a plural form of a satellite, the verb that follows <em>satellites</em> should also be plural. The plural verb in the given options is prove.

As far as the second blank is concerned, you can see Venus is a proper noun; therefore, the verb that comes after <em>Venus</em> should be a singular verb, which in this case is has.

So the complete sentence would become the following:

Telescopes and satellites prove that neither Mercury nor Venus has a moon.

Correct pair: prove:has

Explain why mess extinctions occur and why it make sense to measure geologic time between mass extinctions
Nastasia [14]
Mass extinction occur from natural disasters, such as a n asteroid hitting earth or a volcano errupting and spread ash everywhere.

It makes sense to measure geologic time between mass extinctions because after each mass extinction, there is almost no life left and the few left have to repopulate, which may lead way to new mutations and new varieties of plants and animals.

A parachutist's fall to Earth is determined by two opposing forces. A gravitational force of 605 N acts on the parachutist. Afte
Doss [256]

Answer:15.8 m/s

Explanation:

Given

Gravitational Force F_g=605 N

Air resistance F_d=689 N

mass of Parachutist =\frac{605}{9.8}=61.73 kg

Velocity after 3 s

v=u+at

v=0+9.8\times 3

v=29.4 m/s

Now Parachutist opens the parachute

Net for on Parachutist

605-689=-84

84 N drag force

therefore deceleration \frac{84}{61.73}=1.36 m/s^2

velocity after 10 s is

v_1=v+at

v_1=29.4-1.36\times 10

v_1=15.8 m/s
