<span>The amount of kinetic energy an object has
depends on its mass and speed.</span>
Answer:
Iron
Explanation:
The buoyant force equals to the weight of water being displaced by the object.
Since, the volume of both iron and wood is equal and the wood is not completely submerged, but the iron block is completely submerged i.e more volume of the water is being displaced by the iron block.
Hence, the buoyant force is more on the iron.
Answer:
The velocity is 
Explanation:
From the question we are told that
The electric field is 
The magnetic field is 
Generally the force experienced by the electron due to the magnetic field is
Generally the force experienced by the electron due to the electric field is
Since from the question the net force is zero then
=> 
Substituting values
Saturn's rings are made of billions of pieces of ice, dust and rocks. Some of these particles are as small as a grain of salt, while others are as big as houses.
Answer:
Flemmings' left hand rule and Downward direction
Explanation:
The person could able to determine the path of force by applying the left-hand rule of Fleming.
Via holding the thumb the forefinger and second finger at right angles for one other
The left-hand rule is applied in the electric motors
On the other hand, the right-hand rule is applied for electric generators.
So different hands are used for the different thing as there is a difference between the cause and effect
Therefore in this case there is a left hand rule used and the direction is downward
