Answer:
The value is
Explanation:
From the question we are told that
The mass of the block is
The initial speed of the block before entering the rough section is
The time taken is t = 0.5 s
The speed with which the block leaves the rough section is
Generally from kinematic equation
=>
=>
=>
Generally the magnitude of the average frictional force is mathematically represented as
=>
=>
The negative sign show that the force is acting in the opposite direction to the direction of motion of the block

Answer:
The Storm Surge of a hurricane
Explanation:
A hurricane can ultimately cause a tsunami and is just as deadly.
Answer:
The two waves will add vectorially to produce a small amplitude wave in a valley phase.
Explanation:
The two waves will add vectorially to produce a small amplitude wave in a valley phase. This is because the amplitudes of the waves are slightly different and in opposite directions. When wave 1 cancels out all of wave 2, the resultant wave would be the slight difference between both waves, and it would be in the direction of wave 1 which is a valley phase.
The statement "<span>When an electron is added to a neutral atom of an element to form a negative ion, the resulting change in energy is referred to as the electron potential of that element." is false.
