A cyclist maintains a constant velocity of 4.1 m/s headed away from point A. At some initial time, the cyclist is 244 m from poi

astra-53 [7]

Answer:

$d=490\ m$ is his final displacement from the point A after 60 seconds.

Explanation:

Given:

Cyclist is moving away from A.

velocity of cyclist, $v=4.1\ m.s^{-1}$

displacement of the cyclist from point A at the time of observation, $d_i=244\ m$

time after which the next observation is to be recorded, $t=60\ s$

Now as the cyclist is moving away from point A his change in displacement after the mentioned time:

$\Delta d=v.t$

$\Delta d = 4.1 \times 60$

$\Delta d=246\ m$

<u>Now the the final displacement from point A after the mentioned time:</u>

$d=d_i+\Delta d$

$d=244+246$

$d=490\ m$

a uniform disc and hollow right circular cone have the same formula for their moment of inertia when rotating about the central

Romashka-Z-Leto [24]

Answer:

This is as a result that about the central axis a collapsed hollow cone is equivalent to a uniform disc

Explanation:

The integration of the differential mass of the hollow right circular cone yields

$I=\int\limits dmr^2 = \int\limits^a_b {\frac{2Mxr^2}{R^2 +H^2} } \, dx = \frac{2MR^2dx}{(R^2 +H^2)^2} \frac{(R^2 +H^2)^2}{4} = \frac{1}{2}MR^2$

and for a uniform disc

I = 1/2πρtr⁴ = 1/2Mr².

What is the number at the end of an isotope’s name?

Lera25 [3.4K]

Explanation:

The liquid contains only one element. -The liquid is a pure substance. The number at the end of an isotope's name is the -mass number. While looking at xenon (Xe) on the periodic table, a student needs to find an element with a smaller atomic mass in the same group.
