Continental shelf is the name of the area between the shoreline and the continental slope.

Answer: Option A

<u>Explanation: </u>

The continental shelf refers the continent' edge which presents under the ocean. It expands from the continent' edge to a drop points referred as shelf break. As this break, the underwater edge of the continental shelf initiates to plummet deep into the seabed.

According to convention, the continental shelf of the coastal state includes the sinking area of the coastal state, the seabed and undersea region' subsoil extending beyond its territorial sea to its outer edge point of the continent or 200 km of nautical miles without extending the outer periphery of continental margin.

love history [14]

Answer:

4.44 i + 11.11 j , 11.96 m/s

Explanation:

m1 = 0.2 kg, v1 = 10 m/s along X axis, v1 = 10 i

m2 = 0.25 kg, v2 = 20 m/s along north, v2 = 20 j

After collision they stick together and let they move with velocity v.

Use the conservation of momentum

m1 x v1 + m2 x v2 = (m1 + m2) x v

0.2 x (10 i) + 0.25 x (20 j) = (0.2 + 0.25) x v

2i + 5j = 0.45 v

v = 4.44 i + 11.11 j

magnitude of velocity = $\sqrt{(4.44)^{2}+(11.11)^{2}}$ = 11.96 m/s

Thus, the velocity of 0.250 kg hockey puck is 4.44 i + 11.11 j metre per second and the magnitude of velocity is 11.96 m/s.

Fittoniya [83]

Answer:

I started answering this before everything was erases, but briefly

W = 1/2 K x^2 so K = 2 W / x^2 = 6 * 25 = 150

Also F = - K X = 150 * 1/5 = 30 N at max extension

m = F / a = 30 /15 = 2 kg

Since max extension occurs at t = 0 you can write

x = A sin ω t

v = ω A cos ω t

a = -ω^2 A sin ω t note that there is no phase angle here

Also at .1 compression

.1 = .2 sin ω t and sin ω t = 1/2 and ω t = 30 deg = pi / 6

Substiture these values above to get velocity and acceleration when

ω t = 30 deg

Help pleaseee SOS!! Again

wlad13 [49]

Answer:

A) 7500[N]

Explanation:

This is a problem where we have to apply the pascal principle, in this case replace the given values in the given equation:

F1 = 2500 [N]

A1 = 0.06 [m^2]

A2 = 0.18 [m^2]

$F_{2}=A_{2}*\frac{F_{1}}{A_{1}} \\F_{2}=0.18*\frac{2500}{0.06}\\ F_{2}= 7500[N]$
