Although the acceleration due to gravity is the same on all objects, why do a flower petal

1 answer:

7 0

We know that acceleration due to gravity is the same for all objects. But if we drop a flower petal and a hammer from the same height, the hammer falls faster. Why does this happen?

Let me try to explain. The petal falls slower as the resistance it faces by air slows it down much more. Even though the hammer is also affected by this resistance, the speed decrease is negligible due to its weight.

To simplify, a petal is much lighter than a hammer. Even though gravity accelerates them at the same speeds, the petal slows down due to air resistance but the hammer doesn't, as its weight counteracts the air resistance.

I may be confusing at times, so please ask me if you want anything clarified :)

Hope this helps you!

Answer:

$R=0.023m$

Explanation:

From the question we are told that:

Mass $m=1.16*10^{-26}$

Potential difference $V=523V$

Magnitude $m=0.370 T$

Generally the equation for Velocity is mathematically given by

$\frac{1}{2}mv^2=ev$

$v=\frac{2ev}{m}$

$v=\frac{2*1.6*10^{-19}*542}{1.16*10^{-26}}$

$v=12.22*10^4m/s$

Generally the equation for Force is mathematically given by

$F=qvBsin \theta$

Where

$qVB=m\frac{v^2}{R}$

$F=m\frac{v^2}{R}sin\theta$

Therefore

$R=\frac{mv}{qB sin \theta}$

$R=\frac{1.6*10^{-26}*12.2*10^{4}}{1.60*10^{-19}*0.394 sin 90}$

$R=0.023m$

Explanation:

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Therefore it can not be any of the other answers because the substance was water at first but now its salty water.

ps what kind of person would drink water after you put salt in it lol.
