A. scatter plot (100% positive, btw quizzes is a good tool for answers)
Answer:
21.65 feet
Explanation:
We have a pressure sensor that is to be deployed to the northeast of appledore.
Pressure response factor should be at least 0.1
We have pressure response factor
Kp = 1//cosh kd
To get cosh kd,
1/0.1 = 10
Using the waves table d/Lol is approximately 0.47
Lo = gt²/2pi
After inserting values,
Lo = 1.56x9 = 14.04
d/Lo = 0.47
d/14.04 = 0.47
When we cross multiply,
d = 14.04x0.47
d = 6.60m
When converted to feet's
= 21.65 feet
The question is not complete so i have attached it.
Answer:
The light source is 2 cm from the bottom of the lamp
Explanation:
From the attached image, we can see that the parabola opens up with its vertex at the origin.
Now, the standard form of equation for a parabola is:
x² = 4ay
Looking at the parabola in the attachment, the top right edge of the lamp has a coordinate of (12,18)
Thus, we have;
12² = 4a(18)
144 = 72a
a = 144/72
a = 2
Looking at the parabola again, the line of symmetry is at x = 0
Thus, axis of symmetry is at x = 0.
Thus, focus is at (0, 2)
So, if the light source is placed at the focus, the distance of the light source from the bottom of the lamp is 2 cm
That’s really rude you just typed in a bunch of letters to get points
Given the mass of the car and the change in velocity, the impulse exerted on the car by the brakes is 45000kgm/s.
<h3>What is impulse?</h3>
Impulse is simply the product of force and time.
Using the formula of impulse.
Ft = m( v - u )
Given the data in the question;
- Initial velocity v = 25m/s
We substitute our values into the expression above.
Ft = m( v - u )
Ft = 1800kg( 25m/s - 0m/s )
Ft = 1800kg × 25m/s
Ft = 45000kgm/s
Therefore, Given the mass of the car and the change in velocity, the impulse exerted on the car by the brakes is 45000kgm/s.
