Answer:

An earthquake is a natural rapid shaking of the tectonic plates caused by the release of stored energy in rocks

Explanation:

there are tectonic plates and the earthquake is caused by that energy the plates are always moving so it might get stuck in between each other and store the energy.

Use the following quote to answer the question.

White raven [17]

Answer:The quote above describes the section of a state government that makes the laws. This section, more commonly called "body" or "branch," refers to the legislature of the State of Florida. The quote indeed describes the structure of the legislature of a State. In the U.S., all 50 states have legislatures, and all of them, except for Nebraska, have a bicameral Congress consisting of a Senate and a House of Representatives; Furthermore, besides passing legislation, state legislatures also have other governing functions such as approving a state's budget and initiating tax legislation and articles of impeachment.

A projectile is launched with speed v0 at an angle of θ0 above the horizontal. Find an expression for the maximum height it reac

Step2247 [10]

Answer:

$h= \frac{(v_{o})^{2} sin^{2} \theta o }{2g}$

Explanation:

The parabolic movement results from the composition of a uniform rectilinear motion (horizontal ) and a uniformly accelerated rectilinear motion of upward or downward motion (vertical ).

The equation of uniform rectilinear motion (horizontal ) for the x axis is :

x = xi + vx*t Equation (1)

Where:

x: horizontal position in meters (m)

xi: initial horizontal position in meters (m)

t : time (s)

vx: horizontal velocity in m/s

The equations of uniformly accelerated rectilinear motion of upward (vertical ) for the y axis are:

y= y₀+(v₀y)*t - (1/2)*g*t² Equation (2)

vfy= v₀y -gt Equation (3)

vfy²= v₀y²-2gH Equation (4)

Where:

y: vertical position in meters (m)

y₀ : initial vertical position in meters (m)

t : time in seconds (s)

v₀y: initial vertical velocity in m/s

vfy: final vertical velocity in m/s

g: acceleration due to gravity in m/s²

H= hight that reaches the projectile above its starting point (m)

Data

v₀ : total initial speed

θ₀ : angle of v₀ above the horizontal.

g acceleration due to gravity

Calculation of the componentes x-y of the v₀

v₀x = v₀*cos θ₀

v₀y = v₀*sin θ₀

Calculation of the maximum hight that reaches the projectile above its starting point

When the projectile reaches its maximum height (h), vy = 0:

in the Equation (4)

vfy²= v₀y²-2gh

0= v₀y²-2gh

2gh= v₀y² $h= \frac{(v_{o})^{2}sin^{2} \theta o }{2g}$

2gh= (v₀*sin θ₀)²

$h= \frac{v_{o}^{2} sin^{2} \theta o }{2g}$

A force 6.3 N is applied at a distance 2.1 m from the point of rotation of a wrench. If the force is applied in a direction para

Ganezh [65]

Answer: 0 (zero)

Explanation:

The formula for torque = force × perpendicular distance between force and point of rotation.

Where force = 6.3 N, distance between force and point of rotation = 2.1m

It has been stated from the question that the force is applied in such a way that it is parallel to the position vector.

If we take the magnitude of this position vector, it will give the distance between the force and the point of rotation which still shows that the force is parallel to the rotation point which does not satisfy the condition for torque to occur hence torque is zero.
