7 0

Surface tension and surface energy are two very important concepts discussed in physics. The concepts of surface tension and surface energy are widely used in fields such as fluid mechanics, fluid dynamics, aerodynamics and various other fields. Surface tension is the net intermolecular force on the surface molecules of a liquid. Surface energy is the relevant energy of these bonds. In this article, we are going to discuss what surface tension and surface energy are, their applications, the definitions of surface tension and surface energy, their similarities, and finally the difference between surface tension and surface energy.

An Alaskan rescue plane traveling 39 m/s drops a package of emergency rations from a height of 198 m to a stranded party of 3 ex
MAVERICK [17]

Answer:

y = 0m

y0 = 166m

v0y = 0 m/s

g = 9.8 m/s^2

t = ?

Solve for t:

y = y0 + v0y*t - (0.5)gt^2

0 = 166 - (0.5)(9.8)t^2

t = 5.82 s

Now, using time, we can solve for the range using the equation:

x = vx(t)

x = (40)(5.82)

x = 232.8 m

The impact horizontal component of velocity will be 40 m/s as velocity in terms of x is always constant. To find the impact vertical component of velocity, we use the equation:

v = v0y - gt

v = 0 - (9.8)(5.82)

v = -57.04 m/s

Zielflug [23.3K]

Answer:d=7.94\times 10^5\ m

Explanation:

Given

Speed of Primary wave v_1=8\ km/s

Speed of secondary wave v_2=4.5\ km/s

difference in timing of two waves are 77.2\ s

Suppose both travel a distance of d km then

t_1=\frac{d}{8}\quad \ldots (i)

t_2=\frac{d}{4.5}\quad \ldots (ii)

Subtract (ii) from (i)

\frac{d}{4.5}-\frac{d}{8}=77.2

d[\frac{1}{4.5}-\frac{1}{8}]=77.2

d[0.0972]=77.2

d=794.23\ km

d=7.94\times 10^5\ m
