Answer:
0.217 m/s
Explanation:
The protons in the beam passes undeflected when the electric force is equal to the magnetic force:
qE = qvB
where
q is the proton's charge
E is the magnitude of the electric field
v is the speed of the protons
B is the magnitude of the magnetic field
Re-arranging the equation,
And by substituting
E = 0.5 N/C
B = 2.3 T
We find

The process by which the heat energy is transmitted between the atoms or molecules is known as conduction.
Explanation:
Conduction is the transfer of heat through the material that are caused by temperature gradient with the material ends in heat flux. The heat transfer done by movement and mixing of a fluid is known as convection.
If a fluid is taken and it is kept as stationary. If there is a temperature gradient across that fluid, there would be transfer of heat that occurs in the fluid. It is negligible when compared to convective heat transfer.
Because of the heat transfer from solid to solid, density of liquid changes and start to move in upward direction due to low density. This type of motion is known as convection currents.
Answer:
number 6 is wrong
the answer is pesticides
2.combines are used for harvesting or threshing.so number <em>2</em><em> </em><em>is</em><em> </em><em>w</em><em>rong</em>
at least you tried
Explanation:
there is no such thing as <em>weedicides</em>
Answer:
As we know that science is based upon logic. So the scientific theories have a logical reasoning behind them. So considering that in mind, scientific hypothesis include the motion of sailing rocks by animals, wind, flowing water, magnetic field, humans and gravity. The motion of the rocks by ghosts, God and magic are not scientific theories as we can not prove them logicaly.
