Answer:
D gravity
Explanation:
please mark me brainliest
My calculator is about 1cm thick, 7cm wide, and 13cm long.
Its volume is (length) (width) (thick) = (13 x 7 x 1) = 91 cm³ .
The question wants me to assume that the density of my calculator
is about the same as the density of water. That doesn't seem right
to me. I could check it easily. All I have to do is put my calculator
into water, watch to see if sinks or floats, and how enthusiastically.
I won't do that. I'll accept the assumption.
If its density is actually 1 g/cm³, then its mass is about 91 grams.
The choices of answers confused me at first, until I realized that
the choices are actually 1g, 10² g, 10⁴ g, and 10⁶ g.
My result of 91 grams is about 100 grams ... about 10² grams.
Your results could be different.
Answer:
The time that will pass between the feeling and hearing the explosion is 2,86 secs
Explanation:
First, let's calculate the time that the wave takes to travel until the actors feel the explosion:
Now, the time that pass while the actors hear the sound is:
<em>(Remember that the sound speed in the air is 340 m/s on average)</em>
So, the time between the feeling and hearing is 3,23 - 0,37 = 2,86 secs
Explanation:
23 km/hr x 1.5 hrs = 34.5 km
34.5 km = 34500 meters
Based on the given statement or reasoning above made by a student, what makes her reasoning incorrect is the part where she mentioned that "if they had not been built, she would not be exposed to radioactivity." This is definitely false. What makes this incorrect is that background radiation is a kind of radiation that is emitted by the sun, stars, and other bodies outside the universe and therefore, no one can escape from this. Hope this helps.
