Answer:
<h2>4.1 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 0.205 × 20
We have the final answer as
<h3>4.1 N</h3>
Hope this helps you
Answer:
center of mass of the two masses will lie at x = 2.52 cm
center of gravity of the two masses will lie at x = 2.52 cm
So center of mass is same as center of gravity because value of gravity is constant here
Explanation:
Position of centre of mass is given as

here we have




now we have



so center of mass of the two masses will lie at x = 2.52 cm
now for center of gravity we can use

here we have




now we have



So center of mass is same as center of gravity because value of gravity is constant here
Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.
Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.
Answer: A PN-junction diode is formed when a p-type semiconductor is fused to an n-type semiconductor creating a potential barrier voltage across the diode junction

The metric unit of force is Newton or N. The Newton unit is also equal
to kilogram per meter per second squared. The Newton name came from the late
physicist Isaac Newton. It is also based on the second law of motion.
