Answer:
yes
Explanation:
<em>A critical period?
</em>
<em>A.begins and ends abruptly
</em>
<em>B.begins and ends gradually
</em>
<em>C.is unaffected by stimuli
</em>
<em>D.is unlikely to impact development</em>
<em>correct answer (A.begins and ends abruptly
)</em>
D = 1/2 x g × t²
145 = 1/2 × 9.8 × t²
t = 5.4 s
Answer:
b. 9.5°C
Explanation:
= Mass of ice = 50 g
= Initial temperature of water and Aluminum = 30°C
= Latent heat of fusion = 
= Mass of water = 200 g
= Specific heat of water = 4186 J/kg⋅°C
= Mass of Aluminum = 80 g
= Specific heat of Aluminum = 900 J/kg⋅°C
The equation of the system's heat exchange is given by
The final equilibrium temperature is 9.50022°C
The answer is "friction and air resistance" gravity does some of the work by keeping the object from floating away, but friction and air resistance does the biggest part. Friction is how rough the ground it meaning on tile, dirt, grass, etc... that would slow down the object and air resistance is the gravity pushing on the object also making it stop.
Hope this helps!
It takes an average of 8 minutes and 20 seconds.
