Carbon-12 is described as "Stable". I just had this question on my homework :P Hope it helped!
What i got was
speed of impact that is 44.27 m/s
or 159.38 km/h
time until impact is 4.525
and last is the Energy at impact which I calauated outcome was 73500.00 joules
Here's the vector equation for that situation:
(3m east) + (7m west)
= (3m east) + (-7m east)
= -4 m east
= 4 m west .
Answer:
The actual size is
69.33 nm.
Explanation:
It means that
3 cm is equivalent to 40 nm
So, 1 cm is equivalent to 40 / 3 nm
Thus, 5.2 cm is equivalent to
40 × 5.2 / 3 = 69.33 nm
First, you find the pressure experience by the car at that depth. This pressure is called the hydraulic pressure with the equation: P=density*gravity*depth. The density of water is 1000 kg/m^3; the acceleration due to gravity is 9.81 m/s^2. So, we need a value for the depth. Suppose, the car was underwater 6 m deep. Then the pressure would be:
Pressure = 1000 kg/m3*9.81 m/s^2*6m = 58,860 Pascals
Pressure, by definition, is the force over unit area. Since we know the are of the circular window, we can therefore determine the force exerted by the water to the car's window.
P =F/A
P=F/(π*(0.35/2)^2)
58,860 = F/0.0962
F = 5,663 Newtons
