<u>Answer:</u>
Car will take 17.36 seconds to travel the 290 meter.
<u>Explanation:</u>
We know the equation of motion , where s is the displacement, u is the initial velocity, a is the acceleration and v is the final velocity.
In this case initial velocity = 40 km/h = 11.11 m/s
Final velocity = 80 km/h = 22.22 m/s
Displacement = 290 m
Substituting
Now we have v = u+at, where t is the time taken.
Substituting
22.22 =11.11 + 0.64*t
t = 17.36 seconds
So car will take 17.36 seconds to travel the 290 meter.
I think the correct answer from the choices listed above is option D. If gravity do not affect the movement of the moon, then the moon would move in a straight line <span>at a speed of about 1.022 km/s</span>. Hope this answers the question. Have a nice day.
Explanation:
The pressure exerted in the fluid at that depth is given by :
..............(1)
Where
is the density of the fluid
g is the acceleration due to gravity
h is the depth of the fluid
It is clear from equation (1) that the pressure exerted in the fluid is directly proportional to the depth in a fluid. As the depth increases, the pressure will also increase.
