Answer:
337.5m
Explanation:
<u>Kinematics</u>
Under constant acceleration, the kinematic equation holds:
, where "s" is the position at time "t", "a" is the constant acceleration, "
" is the initial velocity, and 
is the initial position.
<u>Defining Displacement</u>
Displacement is the difference in positions: 
or 
<u>Using known information</u>
Given that the initial velocity is zero ("skier stands at rest"), and zero times anything is zero, and zero plus anything remains unchanged, the equation simplifies further to the following:
So, to find the displacement after 15 seconds, with a constant acceleration of 3.0 m/s², substitute the known values, and simplify:
![\Delta s=\frac{1}{2}(3.0[\frac{m}{s^2}])(15.0[s])^2](https://tex.z-dn.net/?f=%5CDelta%20s%3D%5Cfrac%7B1%7D%7B2%7D%283.0%5B%5Cfrac%7Bm%7D%7Bs%5E2%7D%5D%29%2815.0%5Bs%5D%29%5E2)
![\Delta s=337.5[m]](https://tex.z-dn.net/?f=%5CDelta%20s%3D337.5%5Bm%5D)
<span>Sea breeze can happen during hot summer days because of the
uneven heating rates of water and land.
The land surface heats up faster than the surface of the water during the
day. At this rate, the air above the
land grows warmer than the air atop the ocean. Warmer air is always lighter
than cooler air. As a consequence, warm air is pushed upward causing it to
rise. With this, warmer air rises over the land. As warm air rises over the
land, cooler air over the ocean flows over the land surface to change or
replace the rising warm air.</span>
I think the correct answer is the third statement, electron from escaping from the tube containing the triode. The negative charge on the grid repels any electron in the tube. As a result,the flow of current is controlled. If the field is that strong, all current flow will stop resulting to maintaining the electron cloud in the tube.
D. It happens all the time
A higher frequency. I just got this answer on usa test prep.
