" 478 watts " means 478 joules per second.
In 14 seconds, the total work or energy is (14 x 478) = <em>6,692 joules</em>
Answer:
-2040 m/s²
Explanation:
Taking toward the wall to be positive, the initial velocity is 10.1 m/s and the final velocity is -8.3426 m/s.
Average acceleration is the change in velocity over change in time.
a = Δv / Δt
a = (-8.3426 m/s − 10.1 m/s) / 0.00905 s
a = -2040 m/s²
The answer is D because the mass of H is 1.008 and the mass of Cl is 35.45. When added up the answer is around 36.458. Depending on your periodic table and number of significant figures the values would be different slightly. 36.458 is pretty close to 36.46094 compared to other answers. Hope this helps!
Answer:
Different
Explanation:
The hollow one will expand even more making it have a larger volume then the solid one so they are different
Answer:
where
Pa = Gravitational potential energy of satellite A
Pb = Gravitational potential energy of satellite B
G = gravitational constant
Me = Mass of the earth
Ma = Mass of satellite A
Mb = Mass of satellite B
Re = Radius of the earth
Pb/Pa = (-GMeMb/Re) / (-GMeMa/Re)
Pb/Pa = Mb/Ma
