Non metal ions gain electrons to become negative ions
Answer: μ = 0.8885
Explanation: Force due to friction is calculated as:
At an inclined plane, normal force (N) is: N = mgcosθ, in which θ=32.51.
Power associated with work done by friction is . The variable x is displacement the object "spent its energy".
Power associated with work done by gravitational force is P = mghcosθ, where h is height.
The decline forms with horizontal plane a triangle as draw in the picture.
To determine force due to friction:
Replacing force:
Calculating h using trigonometric relations:
h = sin(32.51)
Coefficient of Kinetic friction is
μ = 0.8885
<u>For these conditions, coefficient of kinetic friction is </u><u>μ = 0.8885</u><u>.</u>
Explanation:
Heat flow = conductivity × area × change in temperature / thickness
q' = kAΔT/t
13.3 W = k (1.56 m²) (7.8°C) / (0.0234 m)
k = 0.0256 W/m/°C
Heat lost by water = heat gained by ice
-mCΔT = mL + mCΔT
-(1000 g) (1 cal/g/°C) (12°C − 37°C) = m (79.7 cal/g) + m (1 cal/g/°C) (12°C − 0°C)
25,000 cal = (91.7 cal/g) m
m = 272.6 g
