It is equal to 10 MegaMeters! :-)
Answer:
14.7 m/sec.
Explanation:
We will go about using the mathematical formula,
Vf - Vo = gT.
To break it down,
Vf = Velocity of the apple just before hitting the ground.
Vo = Initial velocity of apple = 0
T = Time for apple to hit the ground = 1.5 sec
g = Acceleration due to gravity = 9.8 m/sec^2
We then need to substitute appropriate values,
<em>Vf - 0 = 9.8(1.5) </em>
<em />
<em>Vf = 14.7 m/sec. </em>

If the solar system were placed to the edge of the galaxy, the majority of the night sky would be black with few stars.
<h3 /><h3>What is Galaxy?</h3>
A galaxy is a collection of stars, stellar remnants, interstellar gas, dust, and dark matter that is gravitationally bound. The name comes from the Greek word galaxias, which translates to mean "milky" and refers to the Milky Way galaxy, which houses the Solar System.
Because stars are more prevalent near the galaxy's core and less at its extremities, if the Sun and Earth were transported to its edge, we would observe mostly black skies at night and few stars.
We may thus draw the conclusion that if the solar system were transferred to the edge of the galaxy, the most of the night sky would be black with only a few stars.

Answer:
t = 25s
Explanation:
The required temperature change is 50°C. (80 –30). The temperature of the bar increased 2°C in the first second. Assuming uniformity in the properties of the bar, in 2s the temperature would now be 2+2 = 4°C, in 3s it will be 2+2+2 =6°C.
So for gain a temperature change of 50°C, it will take 50/2 = 25s
ΔT /t = 2
t = ΔT/2 = 50/2 = 25seconds
