Well it's a volcano that hasn't erupted. except the 1980 eruption of Mount St Helen. They're exctint, Scientist believe that it will never erupt again
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
Answer:
its probably still trying to load ur next rank or whatever it did it to me too
Explanation:
Answer:
Acceleration,
Explanation:
We are given with a velocity-time graph of an object that starts from origin. y axis is velocity and x-axis is time.
The slope of velocity-time graph gives acceleration of an object. Taking the slope of this graph.
So, the acceleration of the object is .
