<h3>pressure = force / area</h3>
<h3>force = 84 N</h3><h3>pressure = 6 × 10 - 5 = 55 m2</h3>
<h3>pressure = 84 / 55</h3>
<h3>pressure = 1.53 pascals</h3>
hope that helps and please tell me if i am wrong :)
Answer:
20 m/s
Explanation:
The acceleration of an object determines the increase in velocity per second.
In this case the acceleration is 20m/s^2.
That is, the increase is 20m/s each second.
I hope this is useful for you

Answer:
Dont know if this is right but i say C
Explanation:
Answer:
the correct answer is D
Explanation:
When the star explodes the radiation travels through empty space at the speed of light c= 3 10⁸ m/s
This speed has been experimentally proven to be constant, therefore two two instruments arrive at the same time
Therefore the correct answer is D
Answer:
-2.79 x 10²J
Explanation:
using the pressure volume work formula which states that
work = -PΔV
= -(1.0 atm) (2.7-0.0)L = -2.7L . atm
Convert litre.atmosphere to Joules.
1 L . atm = 101.325 joules
-2.75 L .atm = -2.75 x 101.325 = -278.64375 =
Work = -2.79 x 10²J
