Answer:1.318 kN/m

Explanation:

Given

compression x=0.16 m

mass of Plunger m=0.0540 kg

Top speed v_{max}=25 m/s

Conserving Energy

Elastic Potential Energy  of spring stored converted in kinetic energy of Plunger

\frac{1}{2}kx^2=\frac{1}{2}mv^2

k\times (0.16)^2=0.054\times 25^2

k=1318.35 N/m

Calculate the average orbital speed of Ceres in
marin [14]
] Ceres is composed of rock and ice and is estimated to comprise approximately one third of the mass of the entire asteroid belt. Ceres is the only object in the asteroid belt known to be rounded by its own gravity (though detailed analysis was required to exclude 4 Vesta). From Earth, the apparent magnitude of Ceres ranges from 6.7 to 9.3, peaking once every 15 to 16 months,[21]hence even at its brightest it is too dim to be seen with the naked eye except under extremely dark skies.

Which formation is one feature of karst topography?
steposvetlana [31]
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering- resistant rocks, such as quartzite, given the right conditions.
