A bonds with elements from b
Answer:
The acceleration of the box is 1.125 m/s² towards right.
Explanation:
Mass of the box, 
kg
Force acting towards right, 
N
Frictional force acting towards left, 
N
Let the acceleration be 
m/s².
Now, net force acting on the box towards right is given as:
From Newton's second law of motion,
Therefore, the acceleration of the box is 1.125 m/s² towards right.
Correct answer choice is :
D) In a forward-biased setup, large numbers of charge carriers will be pulled across the junction and result in a large current.
Explanation:
P-n junction diode is the easiest mode of all the semiconductor tools. Despite, diodes act a significant role in many electronic appliances. A p-n junction diode can be utilized to change the alternating current to the direct current. These diodes are applied in power supply accessories. Battery attached across the p-n junction causes the diode forward biased, pushing particles from the n-type to the p-type and starting holes in a different way. Electrons and holes cross the junction and join. Photons are carried off as the electrons and holes recombine.
The match making one is Radiation is i think B and Convection i think is C and Conduction i think is A. I think 1 is radiation. Because radiation is transferred between objects or an empty space. Number 2 i think is conduction Because conduction is the transfer of thermal energy between to objects touching. Number 3 i also i think is radiation because radiation transfers between objects. Number 4 i also think is conduction because the spoon was touching a hot pot that was on the stove so then the thermal energy was transferred between the two objects touching. number 5 I think is convection because convection is the transfer of energy by the movement of a fluid, such as air or water. Number 6 i think is radiation because the snake is not touching the lamp and radiation goes all across spaces. Number 7 i think is convection because convection is the movement of a fluid, such as air or water. Hope this helps sorry its so long :)
