Mass movement is the movement of surface materials caused by gravity. A great example would be a mud slide.
Hey i am here to help you.
A: 2 concrete blocks 6cm apart will have the least gravitational attraction to each other.
I believe that this answer was helpful.
Answer:
C. N/m (newtons/meter)
Explanation:
Since the equation for potential energy for a spring is PE = 1/2kx², after you know <em>k </em>and <em>x</em>, you will get an answer in Joules.
Please let me know if you want me to explain further!
Thanks!
To solve this problem it is necessary to apply the concepts related to Torque and Inertia.
Torque is defined as the force applied to a given distance radius, that is
Replacing with our vales we have that
On the other hand the definition of Inertia defines us that it is inversely proportional to angular acceleration and proportional to torque, that is to say
Answer:
(b) 1/sinƟ
Explanation:
A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.
Basically, a simple machine allows for the transformation of energy into work. The six simple machines are; lever, wedge, pulley, screw, wheel and axle, and inclined plane.
Inclined plane is a simple machine set at an angle and then used to lift an object.
In Physics, the velocity ratio of a simple machine is calculated as a ratio of the distance moved by the effort to the vertical distance through which a load is raised.
Mathematically, the velocity ratio of an inclined plane of angle Ɵ, acting as a simple machine is given by the formula;
Velocity ratio (V.R) = 1/sinƟ
Basically, an increase in the angle of inclination (measured in degrees) of an inclined plane increases its velocity ratio.
