10°c
Explanation:
Given parameter;
Lower fixed point = 30mm
Upper fixed point = 180mm
Reading = 45mm
Unknown:
The degree celcuis temperature at 45mm = ?
Solution:
To solve this problem we simply compare the mm- scale to the celcius - scale that we know.
The upper fixed point is the boiling point of water
Lower fixed point is the freezing point of water
This shows that both the upper and lower fixed point of both thermometers are the same;
mm-scale °c scale
180mm 100°c
45mm x
30mm 0°c
Solving;
x (150) = 100 x 15
x = 10°c

Answer: horizontal speed is 3.9 m/s
Explanation: when ball starts to drop, its vertical speed v0 is zero.
We can calculate dropping time from s = v0t +0.5gt².
Dropping time t= √(2s/g)= √((2·8.0 m)/9.81 m/s²)= 1.277 s
Because ball travels horizontal distance s= 5.0 m
HorizontalSpeed v = s/t = 5.0 m/1.277s= 3,915 m/s
Answer:
<em>A = 0.05 V</em>
Explanation:
<u>Sinusoidal Functions</u>
A sinusoid or sinusoidal function is a sine or cosine which general equation is
Or also
Where A is the amplitude or maximum value, w is the angular frequency, t is the time and 
is the phase shift.
Comparing the given expression with the general formula
We can establish that A=50 mV = 0.05 V
Answer:
false
