Answer:
53 minutes
Explanation:
To solve this problem, we need to use common proportions to convert.
= 11.7km * 1mi/1.61km * 1hr/8.2mi * 60min/hr
≈ 53 minutes

Answer:
The speed is
Explanation:
Electric field magnitude (E) and electric force magnitude (F) are related by the equation
with q the charge of the proton (). Because between parallel plates electric field is almost constant, electric force is constant too:
because electric force is constant, then by Newton's second law acceleration (a) is constant too, it is:
with m the mass of the proton ():
Now with this constant acceleration we can use the kinematic equation
with v the final speed, the initial velocity that is zero (because proton starts at rest) and d is the distance between the plates, so:
I think it is a, b, and e. Hope it helps! :)
To look for the acceleration, it will come from:
vf^2=v0^2+2ad
where:
vf = final velocity = 0
v0 = initial velocity =251 m/s
a = acceleration
d= distance traveled = 0.237 m
0=251^2+2a(0.237 )
a= -251 ^2 / (2*0.237) =-132 913.502 m/s/s
we find the force from:
F = ma = 0.0115kg*(-1.32x10^5m/s/s) = -1518 N
the negative sign shows that the force is in the direction contradictory the

For Pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
which becomes
where
is the force on the first piston
is the area of the first piston
is the force on the second piston
is the area of the second piston
If we rearrange the equation and we use these data, we can find the intensity of the force on the second piston:
