Answer:
Explanation:
W = 75 watts
V = 110 volts
Formula
W = V * I
Solution
75 = 110 * I Divide by 110
75 / 110 = I
I = 0.6818 Amperes

Answer:
15.6m/s
Completed Question;
For a short period of time, the frictional driving force acting on the wheels of the 2.5-Mg van is N= 600t^2 , where t is in seconds. If the van has a speed of 20 km/h when t = 0, determine its speed when t = 5
Explanation:
Mass m = 2500kg
Speed v1 = 20km/h = 20/3.6 m/s = 5.556 m/s
To determine speed v2;
Using the principle of momentum and impulse;
mv1 + ∫₀⁵ F dt = mv2
Answer:
a) The total force is 4659.8 N
b) The gauge pressure is 50764 Pa
Explanation:
Given:
Pressure inside = 0
Patm = pressure outside = 1.013x10⁵Pa
Pressure difference = ΔP = 1.013x10⁵ - 0 = 1.013x10⁵Pa
a) The area is equal:
The force is:
b) The gauge pressure at the bottom is equal:
Where:
ρ = density = 1000 kg/m³
h = 17 ft = 5.18 m
Replacing:
