Answer:
Both balls hit the ground simultaneously
Explanation:
Let´s call b₁ ( the ball dropped ) the equation for a free fall movement is, tacking as the origin of coordinates the level from which it was dropped
V = g*t ( since V₀ initial velocity is 0 )
In the case of projectile movement the equation for Vx and Vy (these speeds are independent)
are:
Vx = V₀x (constant) and Vy = Voy + g*t
Vy = V₀ * sin 0⁰ + g*t Vy = 0 + g*t
As we can see V is the same in both cases then the balls hit the ground simultaneously
Answer:
-48,800,000 or 71,200,000
Explanation:
subtraction or addition :D

If the experiment had been repeated with frequencies 10 times lower than those in table 5.2, then Vc will increase 10 times to the values given in the table.
<h3 /><h3>What is frequency?</h3>
It is the number of oscillations per second of the sinusoidal wave.
Vc is the voltage across the capacitor and Xc is the capacitive reactance.
Xc = - 1/2πfC
where f is the frequency and C is the capacitance of the capacitor.
If the frequency is lowered, the potential difference will increase because frequency is inversely proportional to the voltage.
Thus, Vc will increase by lowering the frequency by 10 times.

Answer: The answer to your question is Avogadro's number
Explanation: It describes the number of representative particles in one mole of a substance. The official definition of the mole is the quantity that describes the number of elementary entities as there are atoms in
12
g of isotopically pure carbon-12.
<span>Humans first appeared during the Quaternary period. <span>The Quaternary or Neozoic period develops in the Cenozoic
era, which extends from 2,588 million years ago to the present. The
Quaternary is divided into two periods. The Pleistocene, the first and
longest period of the period, was characterized by the cycles of glaciations
and the appearance of the first humans (homos habilis); this period
extended from 2,588 million years to 10,000 years BC The Holocene, the second
epoch of the period, was characterized by the end of the glaciation and the
emergence of human civilization; this period extends from 10,000 years BC
to the present.</span></span>
