Answer:

Explanation:

Atom, smaller than that and you get into subatomic particles which don't really have the properties of elements they make up.

The valu

natulia [17]

Answer:

$\% Error = 2.6\%$

Explanation:

Given

$x: 1.54, 1.53, 1.44, 1.54, 1.56, 1.45$

Required

Determine the percentage error

First, we calculate the mean

$\bar x = \frac{\sum x}{n}$

This gives:

$\bar x = \frac{1.54+ 1.53+ 1.44+ 1.54+ 1.56+ 1.45}{6}$

$\bar x = \frac{9.06}{6}$

$\bar x = 1.51$

Next, calculate the mean absolute error (E)

$|E| = \sqrt{\frac{1}{6}\sum(x - \bar x)^2}$

This gives:

$|E| = \sqrt{\frac{1}{6}*[(1.54 - 1.51)^2 +(1.53- 1.51)^2 +.... +(1.45- 1.51)^2]}$

$|E| = \sqrt{\frac{1}{6}*0.0132}$

$|E| = \sqrt{0.0022}$

$|E| = 0.04$

Next, calculate the relative error (R)

$R = \frac{|E|}{\bar x}$

$R = \frac{0.04}{1.51}$

$R = 0.026$

Lastly, the percentage error is calculated as:

$\% Error = R * 100\%$

$\% Error = 0.026 * 100\%$

$\% Error = 2.6\%$

The weight of a body is 147N. what is its mass?

barxatty [35]

To find the mass, with only the weight:

⇒ must consider the relationship between the mass and weight

⇒ (in other words) we must find the equation that has both the

mass and weight

Based on our physics knowledge, we know:

$Weight=mass*gravitational_. acceleration$

Weight: 147N
Gravitational Acceleration: 9.8 m/s²

Now let's plug in the values, and solve:

$147N = mass*9.8_.m/s^2\\mass = 15_.kg$

Answer: 15 kg

Hope that helps!

*as a note, if you use the gravitational acceleration as 10m/s², then the answer would be 14.7 kg

A source emits sound at a fixed constant frequency f. If you run towards the source, the frequency you hear is

Ulleksa [173]

Answer:

increased because as you run into each sound wave the time between each sound decreases meaning the period of each wave decreases to your years and since f=1/T and T is decreasing by greater than 0, f must increase.
