The length of the new runway In terms of (L) is 4L.
<em />
<em>Your question is incomplete, it seems your question is missing the following information below;</em>
"In terms of (L) , what must be the length of the new runway?"
The given parameters;
- length of the runway, = L
- let the take off speed = V₁
For the newly designed planes;
the take off speed is double of the original = 2V₁
the acceleration for both take is constant = a
The take off speed for the given constant acceleration is given as;

The length of the new runway In terms of (L) is calculated as follows;

Thus, the length of the new runway In terms of (L) is 4L.

Answer:

Explanation:
Given:
radius of capillary, 
angle of contact, 
density of water, 
surface tension of water, 
height, h = ?
We have the equation for the height of meniscus as:



No, the capillary action alone cannot be the mechanism of water transportation to the top of the trees. Transpiration also creates a suction pressure in the xylem complementary to the ascent of sap and cohesion of water being the other causes of movement of water up in the plants.

Answer:
A- The ball has both kinetic and potential energy,
Explanation:
kinetic energy by virtue of its motion.
potential energy by virtue of its position. (It could roll off the edge of the tabel and convert gravity potential energy to kinetic energy)
Answer:
Explanation:
To calculate an effect size, called Cohen's d , for the one-sample t-test you need to divide the mean difference by the standard deviation of the difference, as shown below. Note that, here: sd(x-mu) = sd(x) . μ is the theoretical mean against which the mean of our sample is compared (default value is mu = 0).
