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

Answer:
The ability of solid rock to flow is called Plasticity.
Explanation:
Plasticity is the deformation of a solid material which resulted in non reversible changes of shape in response to applied force.
At the peak of its trajectory, the ball's vertical velocity (v1,y) is zero, whereas its horizontal velocity (v1,x) maintains its consistency. The accelerations a1,x and a1,y are 0 and -9.8 m/s² respectively.
The physical concept analyzed here is projectile motion. Considering the trajectory of a ball, we can separate its motion into horizontal and vertical components. At the peak of its trajectory (time t1), the ball's vertical velocity (v1,y) is zero, because it temporarily stops moving upwards before it begins to fall again. However, since there is no acceleration in the horizontal direction (a1,x), the ball keeps moving horizontally with constant velocity (v1,x).
The acceleration in the vertical direction (a1,y) is still the acceleration due to gravity (-9.8 m/s²). This is because even at the peak of the trajectory, the ball is still accelerating downwards. Therefore, the correct answer should include v1,y = 0 m/s, v1,x = consistent value, a1,x = 0 m/s², and a1,y = -9.8 m/s². So the most probable answer is D) 15.0, 0, 0, -9.80, assuming the ball's horizontal velocity is 15 m/s. Please check the exact value of horizontal velocity (v1,x) in the settings of your problem.

hydrogen from which stars are formed
b. luminosity.
c. distance from Earth.
d. absolute magnitude. E. surface temperature.
Answer:
Luminosity
Explanation:
The apparent magnitude is a measure of the star's apparent luminosity, the apparent luminosity is directly related to the star's apparent magnitude.
The star's luminosity is the measure of the star's brightness and this diminishes with distance, the luminosity of a star also depends on the size of the star, this means that a star's magnitude and luminosity are directly related.
Express your answer numerically, in minutes.
b)Find Anya's average speed.
Express Anya's average speed save,Anya numerically, in miles per hour
C)How long does it take Ilya to cover the distance?
Express the time tIlya taken by Ilya numerically, in minutes.
d)Now find Ilya's average speed.
Express Ilya's average speed save,Ilya numerically, in miles per hour
Answer:
Part a)
Part b)
Part c)
Part d)
Explanation:
Speed while she is running = 8.90 mph
speed while she walk = 3.80 mph
Part a)
Anya walks half the distance
so time to walk
time to cover the distance while she run
total time to cover the distance
Part b)
Average speed is given as
Part c)
Half the time Llya walks and next half the time she runs
so total distance is given as
so we have
Part d)
Average speed is given as
