Answer:
The fulcrum of the metre stick is at the 40 cm mark
100 g * 10 cm = 1000 g-cm clockwise torque
x * 30 cm = 1000 gm-cm = counterclockwise torque for balance
X = 1000 / (40 -10) = 1000 / 30 = 33.3 gm at 10 cm to balance
The last choice is your answer, I just did it.
Answer:
Explanation:
1500 m (100cm/m) / 3 cm/yr = 50 000 yrs.
Based on the 95% confidence interval, the conclusion would be that the whale-watching company has a 95% chance of seeing between -.507 and 1.307 whales on any given day.
<h3>Why can this conclusion be drawn?</h3>
The test was to find out how many whales could be seen on a given day and this was tested at a 95% significance level.
The 95% confidence interval was shown to be (-0.507, 1.307). This means that there is a 95% chance that between -0.507 and 1.307 whales will be seen on a given day.

The magnitude of electric field is produced by the electrons at a certain distance.
E = kQ/r²
where:
E = electric field produced
Q = charge
r = distance
k = Coulomb Law constant 9 x10^9<span> N. m</span>2<span> / C</span><span>2
Given are the following:
Q = </span><span>1.602 × 10^–19 C
</span><span>r = 38 x 10^-9 m
Substitue the given:
E = </span>
E = 998.476 kN/C
