A rainbow. Dispersion is the splitting of radiation into it's different wavelengths.
Answer:
-5m/s
Explanation:
Since
acceleration=final velocity-initial velocity/time
2.5m/s^2=20m/s- initial velocity/10s
2.5m/s^2×10s= 20m/s -initial velocity
25m/s=20m/s - initial velocity
Initial velocity=20m/s-25m/s
= -5m/s
The alarm is going off because the alarm has already been set to activate.
ima freaking 8 how should I know lol
The temperature rise of the body after 30 min is 1.0 °C.
<u>Explanation</u>:
The heat capacity of water is equal to one and it is the number of calories needed to raise the temperature of one gram by 1 degree celsius.
Cp = 1 cal/ g°C
(0.80)170 kcal/hr
(1000 cal/kcal)
(30 min) / 60 min/hr = 68000 cal.
68000 cal / 1 cal/ g°C / (70 kg (1000 g / kg)) = 1.0 °C.
