Temperature doesn't really affect solubility on liquids so it can only be D besides it's already a liquid....
Answer:
300 cos 30 = 40 a + 40 * .2 * 10
Total force = mass * acceleration + frictional force
260 = 40 a + 80
a = 180 / 40 = 4.5 m/s^2
Check:
15 a + 15 * 10 * .2 = T acceleration of 15 kg block (assuming a = 4.5)
T = 15 (4.5) + 30 = 97.5 force required to accelerate 15 kg block
260 - 97.5 = 162.5 net force on 25 kg block
162.5 = 4.5 (25) + 25 * 10 * .2
162.5 = 112.5 + 50 = 162.5
4.5 m/s^2 checks out as correct
Answer:
the answer to the question is a system of insulating element designed to control the path of electric current for a particular purpose
Answer:
An electric generator is a device that converts a form of energy into electricity.
Explanation:
<span>PE = m * g * h
PE = 60 * 9.8 * 4
PE = 2352 J
Power = E/t
Power = PE/t
Power = 2352/4.2
Power = 560 Watt</span>
