Answer:

The primary factors that influence the intensity of shaking during an earthquake include the depth of the quake, its distance from the fault line, the type of soil below, and specifics about the buildings—especially their height. We will focus on the last two (soil quality and structures) and their interaction.

Two friends, Burt and Ernie, are standing at opposite ends of a uniform log that is floating in a lake. The log is 3.2m long and

Softa [3030]

Answer:

x = 0.29 m

Explanation:

It is known that the total external force acting on the mass system equals ZERO,

so the center of mass of the entire system will stay stationary.

We find that

$m_1\Delta x_1 + m_2\Delta x_2 + m_3\Delta x_3 = 0$

Since Ernie approaches Burt's position, we have:

$33 x + 290 x + 32(-3.2 + x) = 0$

$355 x = 102.4$

therefore, we conclude that

$x = \frac{102.4}{355}$

$x = 0.29 m$

ValentinkaMS [3465]

The tension calculated is 236 N. The formula for tension is T = mg + ma. With the following values: m = 20 kg, g = 9.8 m/s², and a = 2.0 m/s², we find T = m(g + a) = 20(9.8 + 2.0) = 20(11.8) = 236 N.

Two charges of 15 pC and −40 pC are inside a cube with sides that are of 0.40-m length. Determine the net electric flux through

Keith_Richards [3271]

To address this issue, we will utilize the principles related to Gauss' law, which states that the electric flux across a surface corresponds to the object's charge divided by the permittivity of vacuum. In mathematical terms, this can be expressed as

$\phi = \frac{Q_{net}}{\epsilon_0}$

It's crucial to remember that the net charge equals the difference between the two specified charges, so upon substitution,

$\phi = \frac{(15-40)*10^{-12}C}{8.85*10^{-12}C^2/Nm^2}$

$\phi = 2.82WB$

The negative sign indicates that the flux is directed into the surface

A gas is enclosed in a cylinder fitted with a light frictionless piston and maintained at atmospheric pressure. When 254 kcal of

serg [3582]

Answer:

Explanation:

The atmospheric pressure is P = 10⁵ N/m²

The volume change is Δ V = 16 - 12 = 4 m³

Work done by the gas at constant pressure can be expressed as:

W = P Δ V

Substituting in values:

Work done = 10⁵ x 4

W = 4 x 10⁵ J.

Part B) The heat added is Q = 254 x 10³ cals

= 254 x 4.2 x 10³ J

= 10.66 x 10⁵ J

According to the first law of thermodynamics:

Q = Δ E + W

Where Q denotes heat energy added, Δ E represents the increase in internal energy, and W signifies the work performed by the gas.

Substituting the known values:

10.66 x 10⁵ = Δ E + 4 x 10⁵

Therefore, Δ E = 6.66 x 10⁵ J.
