If the three spoon touch nothing happens because they are all at room Temperature
Answer:
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Explanation:
This is an exercise of average speed, which is defined with the variation of the distance in the unit of time
v = (y₃ - y₂) / (t₃-t₂)
the midpoint of a magnitude is the sum of the magnitude between 2
t_mid = (t₂ + t₃) / 2
the same reasoning is used for the mean acceleration
a = (v_f - v₀) / (t_f - t₀)
in our case
a = (v₃₂ - v₂₁) / (t₃₂ -t₂₁)
Answer:
<em><u>A.9</u></em><em><u> </u></em><em><u>kWh</u></em>
Explanation:
Tv is rated 0.1 kW
in one day energy used will be 0.1kW ×3hr=0.3kwh
in 30 days energy used will be 0.3kwh×30=9kwh
No isnt it decreasing to the right in a negative acceleration
