What would happen to a loop in a metal tube when it is heated

The ability of solid rock to flow is called _____.

zysi [14]

The ability of solid rock to flow is called Plasticity.

Plasticity is the deformation of a solid mateial which resulted in non reversible changes of shape in response to applied force.

Another example of plasticity is when you bend metal through a forcer force to create an art or kitchen set

You are standing a distance of 17.0 meters from the center of a merry-go-round. The merry-go-round takes 9.50 seconds to go comp

GenaCL600 [577]

Answer:

(a)11.24 m/s

(b)7.44 m/s

(c)409 N

(d) $539.55\mu$

(e) 0

Explanation:

The period for 1 circle $2\pi$ of the merry go around is 9.5s. It means the angular speed is:

$\omega = \theta / t = 2\pi / 9.5 \approx 0.661 rad/s$

(a)The speed is

$v = \omega * R = 0.661 * 17 = 11.24 m/s$

(b) Centripetal acceleration:

$a = \frac{v^2}{R} = \frac{11.24^2}{17} = 7.44 m/s^2$

(c) Magnitude of the force that keeps you go around at this acceleration

$F = ma = 55 * 7.44 = 409 N$

(d) let the coefficient of friction by $\mu$ . The frictional force shall be this coefficient multiplied by normal force reverting gravity of the man

$F_f = mg\mu = 55*9.81\mu = 539.55\mu$

How many Mars-sized planets can fit in Jupiter

Maru [420]

Answer:

You could put over six planets the size of Mars inside the Earth. The largest planet in our Solar System, Jupiter's size is astounding. Jupiter has a volume of 1.43 x 1015 cubic kilometers. To show what this number means, you could fit 1321 Earths inside of Jupiter

A student was traveling to see his grandmother who lives 15 miles north oh his home he started from rest and maintained a pace o

N76 [4]

Explanation:

Given parameters:

Distance = 15miles north = 24140.2m

Initial velocity = 0m/s

Final velocity = 4m/s

Unknown:

Speed, velocity and acceleration = ?

Solution:

The speed is the distance divide by time. It is a scalar quantity and has no directional attribute.

Speed = $\frac{distance }{time}$

The speed of the student is 4m/s

Velocity is the displacement divided by time. It is a vector quantity which specifies the direction and magnitude;

Velocity = $\frac{displacement}{time}$

The velocity of the student is 4m/s due north

Acceleration is the change in velocity with time;

To find the acceleration, we use

v² = u² + 2as

v is the final velocity

u is the initial velocity

a is the acceleration

s is the distance

4² = 0² + 2x a x 24140.2

a = $\frac{16}{2 x 24140.2}$ = 0.00033m/s²
