Because the particles of a solid are not free to move,
no matter how hot and buoyant they become.
Explanation:
Minimum of aerobic activity 150 minutes, or a mix of moderates and intensive exercise 75 minutes of vigorous aerobic activity a week. We can extend this practice throughout the week with the instructions. Mild aerobic workouts might include practices like quick strolling or swimming, while activity like running can include strong aerobic activity.
Lets suppose center of cube as origin.
All charges are equidistant from this point .
Distance = 0.5*s*√<span>(3). </span>
Total work done = 8*(9*10^9)*q/(0.5*s*√<span>(3) =
Total work </span><span> required to assemble eight identical point charges= </span>(8.31*10^10)*q J
Answer:
1 cm ± 0.05 cm
Explanation:
A ruler is readable to ±0.05 cm. This implies that any measurement taken using the ruler could be uncertain by 0.05 cm above or below the true value.
Hence, ±0.05 cm is called the uncertainty or the precision of the ruler.
We obtained this from the fact that the meter rule is graduated in units of centimetres (cm). This implies that the smallest scale division is 1 mm. Thus, the uncertainty of the meter rule is given by; Δx = smallest increment/2 = 1mm/2 = 0.5mm = 0.05cm.
This is easy
Number 2 is 20 N to the right
Number 3 is 30 N up
Both are unbalanced
