Answer: tectonics

Plate tectonics is the movement of the lithospheric plate over the underlying mantle. It results in the breakage of lithospheric plates into number of plates which floats and travel on the surface of earth's mantle. This occurs due to geological processes like earthquakes and volcanic activity.

Scientists are expected to share their results by

shepuryov [24]

Answer:

Publishing results of research projects in peer-reviewed journals enables the scientific and medical community to evaluate the findings themselves. It also provides instructions so that other researchers can repeat the experiment or build on it to verify and confirm the results.

A 5.0 g coin is placed 15 cm from the center of a turntable. The coin has static and kinetic coefficients of friction with the t

Kaylis [27]

Answer:

Angular speed will reach 6.833rad/s before the coin starts slipping

Explanation:

There is no question but I'll asume the common one: Calculate the speed of the turntable before the coin starts slipping.

With a sum of forces:

$Ff = m*a$

$Ff=m*V^2/R$

At this point, friction force is maximum, so:

$\mu*N=m*V^2/R$

$\mu*m*g=m*V^2/R$

Solving for V:

$V=\sqrt{\mu*g*R}$

V=1.025 m/s

The angular speed of the turntable will be:

ω = V/R = 6.833 rad/s This is the maximum speed it can reach before the coin starts slipping.

It takes Harry 34 s to walk from x1 = -11 m to x2 = -54 m .

miss Akunina [59]

Missing question:
"What is his velocity? Please answer using two sig figs in m/s."

Solution
The relationship between velocity (v), space (S) and time (t) is
 $v= \frac{S}{t}$
The space covered by Harry is
 $S=x_1 - x_2 = -11 m-(-54 m)=43 m$
and so the velocity is
 $v= \frac{43 m}{34 s} =1.26 m/s$
