Answer:
To distinguish results based on the only two variables of
awareness.
Explanation:
<span>D. When velocity at a maximum, acceleration is also at a maximum.
Acceleration is the rate of change of velocity so, it is directly proportional to it, hence, when it will increase velocity will also increase

Answer:
-47 °C
Explanation:
Speed of sound in air at sea level is:
v = 331 m/s + 0.6 m/s/°C T
where T is the temperature in Celsius.
The speed of sound is also the frequency times the wavelength:
v = fλ
Therefore:
fλ = 331 m/s + 0.6 m/s/°C T
(658 Hz) (0.46 m) = 331 m/s + 0.6 m/s/°C T
302.68 m/s = 331 m/s + 0.6 m/s/°C T
-28.32 m/s = 0.6 m/s/°C T
T = -47.2 °C
Rounding to two significant figures, the temperature is -47 °C.
Answer: Dynamic balance
Explanation: Dynamic balance movements are movements in which constant agonist-antagonist muscle contractions occur in order to maintain a certain position or posture. ISSA pg 121
I think the first one is 40*40
