Answer:
Explanation:
the force that you applied caused the notebook to move.
the force applied on the notebook by the table causes it to stop moving.
this is because after sometime the book uses up the force and later the force you applied is less than that of the force by the table.
My answer -
You can tell the speed of a car at any instant by looking at curved path but it does not move with the average speed of any object moving in a straight line.
P.s
Happy to help you have a AWESOME!!!! day ^-^

Answer</h2>
The <u>electron affinity in chemical reaction</u> decides the formation of breakdown of substance
<h2>
Explanation</h2>
Within the chemical reactions, different reactants are come together to make the new compound to complete up to the reaction. The reaction is based on the stability of reactants and the electron affinity of these reactants. The oxidation and reduction process within the reaction is also the main reason to combine or break the substance. For example

The hydron has the ability to lose electron and fluorine has the ability to gain an electron. The strong or weak electron affinity of this element makes the new compound HF.
Answer:
R = 3.88 m
Explanation:
As the Chinook salmon leaves the water till it gets back into the water it is performing a projectile motion with the following parameters:
V₀ = Launch Speed = 6.7 m/s
θ = Launch Angle = 29°
R= Range of Projectile= Horizontal Distance Covered by Chinook salmon= ?
The value of the range of a projectile is given by the following formula:
R = (V₀² Sin 2θ)/g
R = [(6.7 m/s)² Sin {(2)(29°)}/(9.8 m/s²)]
R = [(6.7 m/s)² Sin (58°)/(9.8 m/s²)]
<u>R = 3.88 m</u>
Answer: (B). Solar cell B, because it generates more power.
Explanation:
Given that,
For solar cell A
Energy = 100 Joules
Time = 3 minutes = 180 sec
Power of cell A
Power = Energy/Time


For solar cell B
Energy = 200 joules
Time = 5 minutes = 300 sec
Power of cell B
Power = Energy/Time


Hence, Solar cell B, because it generates more power.
