Crust

Explanation:

The crust is the layer of the earth with the least dense materials. The crust is made up of silicate materials.

  • During the early stage in the formation of earth.
  • The earth differentiated minerals based on their densities.
  • Lighter minerals stayed afloat while the denser ones sank to the core of the earth.
  • The core is made up of the most dense metallic minerals.
  • As we go deep into the earth density increases.
  • Density of crust ranges from 2.-3.3g/cm³
  • The core is about 13.8g/cm³ dense.

Answer:

D) momentum of cannon + momentum of projectile= 0

Explanation:

The law of conservation of momentum states that the total momentum of an isolated system is constant.

In this case, the system cannon+projectile can be considered as isolated, because no external forces act on it (in fact, the surface is frictionless, so there is no friction acting on the cannon). Therefore, the total momentum of the two objects (cannon+projectile) must be equal before and after the firing:

p_i = p_f

But the initial momentum is zero, because at the beginning both the cannon and the projectile are at rest:

p_i = 0

So the final momentum, which is sum of the momentum of the cannon and of the projectile, must also be zero:

p_f = p_{cannon}+p_{projectile} =0

Svet_ta [14]

Answer:

0.44807175m

Explanation:

k = Spring constant = 4\times 10^{4}\ N/m (Assumed, as it is not given)

g = Acceleration due to gravity = 9.81 m/s²

Total mass is

m=26\times 67+3\times 15+5\times 3+25\\\Rightarrow m=1827\ kg

The total weight will balance the spring force

mg=kx\\\Rightarrow x=\dfrac{mg}{k}\\\Rightarrow x=\dfrac{1827\times 9.81}{4\times 10^{4}}\\\Rightarrow x=0.44807175\ m

The springs are compressed by 0.44807175m

A sinusoidal, transverse wave that propagates in the positive x-direction can be described with the wave function y of xt is equ
myrzilka [38]

Answer:

\omega =\frac{2 \pi }{T} rad/s

Explanation:

The wave function is:

y(xt) = Acos(kx- \omega t)

where :

k = wave number

x = position of a point on the wave

\omega = angular frequency

t = time

What is another way to express the angular frequency (omega)

Angular frequency (omega) can be express as :

\omega =\frac{2 \pi }{T} rad/s ( i.e one repetition that it takes to repeats itself)
