Answer:

The correct answer is A. The seamounts that formed the Hawaiian Islands were underwater volcanoes.

Explanation:

All Hawaiian islands are of volcanic origin. They were caused due to the shift of tectonic plates beneath the Pacific Ocean toward the northwest, that caused the formation of many volcanoes. Currenlty, the hot spot does not shift and slowly creates new volcanoes. Due to the location of the hot spot, the only active volcanoes are located in the southern half of the Big Island.

A bicyclist of mass 88.0 kg puts all his weight on each downward-moving pedal as he pedals up a steep road. Take the diameter of

Eduardwww [97]

Answer:

142.296 Nm.

Explanation:

Torque: This is the force that tend to cause a body to rotate or twist. The S.I unit of torque is Nm.

From the question,

T = F×r.................... Equation 1

Where T = Torque, F = Force, r = radius of the circle.

Note: F is the weight of the bicyclist.

Then,

F = W = mg............... Equation 2

Substitute equation 2 into equation 1

T = mgr................... Equation 3

Given: m = 88 kg, g = 9.8 m/s², r = 0.33/2 m

T = 88(9.8)(0.33)/2

T = 142.296 Nm.

A satellite is in a circular Earth orbit of radius r. The area A enclosed by the orbit depends on r2 because A = πr2. Determine

Salsk061 [2.6K]

Answer:

a. $T=r^{3/2}$

b. $K=\frac{1}{r}$

c. $v=\frac{1}{\sqrt{r}}$

d. $v=\sqrt{r}$

Explanation:

To make analysis about the satellite circular earth the depends or r and A

$T^2=\frac{4\pi}{GM}*r^3$

$K=\frac{GM*m}{2*r}$

$T^2=r^3$

$T=r^{3/2}$

$K=\frac{GM*m}{2}*\frac{1}{r}$

$K=\frac{1}{r}$

$K=\frac{1}{2}*m*v^2$

$v^2=\frac{2*K}{m}=\frac{2*Gm*m}{2*m*r}$

$v=\frac{1}{\sqrt{r}}$

$v=\sqrt{2*GMr}$

$v=\sqrt{r}$
