As one distance is including twice, we can use the formula,
S = 2s1s2 / s1+s2
S = 2*3*5 / 3+5
S = 30 / 8
S= 3.75 m/s
So, your final answer is 3.75 m/s
Hope this helps!
Answer:
51520J
Explanation:
The energy added to the piece of glass is also called heat needed to increase its temperature from 10°C to 50°C and it depends on the mass, specific heat capacity and the change in temperature.
Q=m.c.ΔT
Q=(2kg).(644J/(kg°C)).((50°C)-(10°C))
Q=51520J
Answer:
the temperature and volume
Added because force increase as it experiences drag.
