7 0

Answer:

63.0 x (6.02 x 10^23) = 3.79 x 10^25 atoms of gold

Explanation:

There are 6.02 x 10^23 representative particles in a mole of any substance. Multiply it by the number of moles, and you will get the number of representative particles (atoms, molecules, formula units)

Considering the given evidences for Alfred Wegener’s theory of continental drift;

  • Scientists find fossils of species in the Arctic that typically lived in warmer areas is a form of climatic evidence
  • Scientists spot fossils on different continents that look similar and prove to be the same age is a form of biological evidence
  • Scientists observe that some mountain ranges on different continents tend to look alike is a form of geological evidence

<h3>What is Alfred Wegener’s theory of continental drift?</h3>

Alfred Wegener’s theory of continental drift is the theory that the whole continents were once one supercontinent which as  a result of geological activities broke up into the different continents which then drifted apart.

Considering the given evidences for Alfred Wegener’s theory of continental drift;

  • Scientists find fossils of species in the Arctic that typically lived in warmer areas: It is a form of climatic evidence
  • Scientists spot fossils on different continents that look similar and prove to be the same age: It is a form of biological evidence
  • Scientists observe that some mountain ranges on different continents tend to look alike: It is a form of geological evidence

In conclusion, Alfred Wegener’s theory of continental drift describes how the continents of today were formed.

I don't want the answer i just need help on figuring out how to solve this!

Answer:

<u>Yes, it will be a Home Run</u>

Explanation:

(Note : It is assumed that the collision between bat and ball is perfectly elastic.)

( Also I don't know anything about baseball, so I checked the dimensions online, which are minimum 325 ft (left and right field foul pole) and minimum 400 ft centre field fence)).

<u>STEP 1</u>

<em>Find</em><em> </em><em>Horizontal</em><em> </em><em>Range</em><em> </em><em>of</em><em> </em><em>Projectile</em><em> </em>

R =  \frac{ {u}^{2} \sin(2 \alpha )  }{g}  =  \frac{(49.1)^{2}  \sin(44°) }{g}

R = 170.8 \: m \:  = 560.3 \: ft

Therefore, the ball will travel 560.3 ft horizontally well beyond 400 ft (largest dimension of the field), and it'll be a Home Run.

Find the acceleration for a force of 2 N acting on 2 kg.
igomit [66]

Answer:

The acceleration of a 2 kg box acted on by a net force of 2 N is solved by using Newton’s second law of motion in the form acceleration = F_net / mass. Since the mass of the box is 2 kg and the net force is 2 N, the acceleration of the 2 kg box is 1 m/s^2.
