Answer:
<h2>760 m/s</h2>
Explanation:
The jet's speed or final velocity can be found by using the formula
<h3>v = u + at</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have
v = 600 + 20(8)
= 600 + 160
We have the final answer as
<h3>760 m/s</h3>
Hope this helps you
is there more to this? if so i would love to help you!!
Answer:
an active galaxy is the galaxy that produces large amounts of energy in a very small volume of space.
Explanation:
active galaxies such as the M87 gives out extremely bright straight jets having speeds close to the speed of light providing the evidence that power in active galaxies is concentrated in a small region. this power from such a small region cannot be generated throught nuclear fusion as it happens in stars, this is the region why the concentration of matter in the center of this galaxies is not made up of stars.
think its chemistry, hope that helps love
Answer:
Force that the output plunger applies to the car; F2 = 3888N
Explanation:
For a hydraulic device, the relationship between the force and the area using Pascal's principle is;
F1/A1 = F2/A2
Where;
F1 is force applied to the input piston
F2 is force that the output plunger applies to the car
A1 is Area of input piston
A2 is area of larger piston
We are given;
R2/R1 = 9
So,R2 = 9R1
F1 = 48N
Area of input piston;
A1 = π(R1)²
Area of output piston;
A2 = π(9R1)²
Since, (F1/A1) = (F2/A2)
Thus;
F1/(π(R1)²) = F2/(π(9R1)²)
If we simplify, π(R1)² will cancel out to give;
F1 = F2/9²
Thus;
F2 = 9² x F1
Plugging in 48N for F1, we have;
F2 = 9² x 48
F2 = 81 x 48
F2 = 3888N
