Answer:
magnification is 4
Explanation:
m= image height / object height
m= 12/3
m= 4
Answer:
I'm not super sure what your asking for. But these look like elements of communication from a speech or communications class.

- The sender (or encoder) encodes the message and sends it.
- The receiver (or decoder) decodes the message and receives it, then gives feedback to the sender.
- The channel is the medium through which the message is sent: this could be social media, email, text, talking, you name it.
- Body language can assist (or not) in sending the message.
Answer:
The ladder is 3.014 m tall.
Explanation:
To solve this problem, we must use the following formula:
v = x/t
where v represents the woman’s velocity, x represents the distance she climbed (the height of the ladder), and t represents the time it took her to move this distance
If we plug in the values we are given for the problem, we get:
v = x/t
2.20 = x/1.37
To solve this equation for x (the height of the ladder), we must multiply both sides by 1.37. If we do this, we get:
x = (2.20 * 1.37)
x = 3.014 m
Therefore, the ladder is 3.014 m tall.
Hope this helps!
In this problem, we apply the equation regarding kinematics expressed as vf^2 = v0^2 + 2as vf eventually becomes zero because the ball stops in the end. a = -9.8 m/s2s = 2 metres this time
This gives initial velocity, vo equal to 6.26m/s
now 6.26-(-8.85) = 15.11m/s
change in velocity/change in time = average acceleration 15.11/(12/1000) = 1259.167 m/s^2
