Answer: 12.0 m/s^2
Explanation:
Let 
be the angular acceleration of the end of the rod
Taking torque about the link, we have:
Torque is also given in terms of moment of inertia of the rod and its angular acceleration i.e.
From equations (i) and (ii) we have:
The acceleration of the end of the rod farthest from the link is given by:
A material's ability not to break is called ductility.
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0
1. D
Intrusive igneous bodies are rock bodies that are formed due to the flow of magma. In classifying igneous bodies, their size, shape, and relationship(s) with the surrounding rock layers are all considered.
2. B.
A batholith is the largest type of igneous body and it extends to unknown depths within the Earth's crust. These bodies are the size of mountains and are composed mainly of intermediate rock types like granite.
3. B
This igneous body is formed when magma intrudes into rock fractures and then crystalizes there. Through this crystallization, the newly formed rock cuts through the existing rock layers.
A cup of tea/coffee transfers heat via conduction, convection and radiation.
Conduction:
- Heat transfer from a coffee to the spoon is in direct contact
- Inner part of the tea cup against hot liquid will transfer heat to the outer part and saucer.
Convection:
Movement of molecules within the coffee. Hot molecules of the tea at the middle of the drink will be eventually make their way to the outer part of the drink near the tea cup, where they will loose their heat.
Radiation:
Thermal radiation is the loss of heat from a solid object in to atmosphere via the release of electromagnetic radiation. So hot outer edge of the teacup loss the energy to its surroundings via thermal radiation.
