If <em>v</em> is the truck's final velocity, then
<em>v</em>² - (2.0 m/s)² = 2 * (2.00 m/s²) * (400.0 m)
<em>v</em>² = 1604 m²/s²
<em>v</em> = 40.05 m/s ≈ 40 m/s
Answer:
1807.56 kJ
Explanation:
Parameters given:
Current, I = 8.9A
Time, t = 4.7hrs = 4.7 * 3600 = 16920 secs
Voltage, V = 12V
Electrical energy is given as:
E = I*V*t
Where I = Current
V = Voltage/Potential differenxe
t = time in seconds.
E = 8.9 * 12 * 16920
E = 1807056 J = 1807.056 kJ
Your stomach, as in JUST your stomach?
Well the role of your stomach is to break down large clumps of food. Without that it would be very hard to impossible to digest food.<span />
Answer:
The heat flow through the slab in a day is 432,000 J
Explanation:
Q = kA∆T/t
Q is rate of heat flow
k is thermal conductivity = 0.1 J/s/m.°C
A is area = 100 cm^2 = 100 cm^2 × (1 m/100 cm)^2 = 0.01 m^2
∆T is temperature difference = 100 °C
t is thickness = 2 cm = 2/100 = 0.02 m
Q = 0.1×0.01×100/0.02 = 5 J/s
In a day, there are 24×60×60 = 86,400 s
Heat flow in a day = 5 J/s × 86,400 s = 432,000 J
Transparent objects allow all the light to pass through them, translucent ones allow partial light to pass, whereas opaque ones allow no light to pass through.
