The primary method of heat transfer when ironing clothes is conduction. The iron heats up very quickly because it is metal, which is a good conductor.
It should be noted that after the big bang occurred, the universe "Became Denser" (Option B)
<h3>What is the explanation for this?</h3>
According to the Big Bang Theory, after the explosion which triggered the transformation of radiation into matter, gravity pulled dark matter together which in turn attracted normal matter.
Hence, it is right given the above analogy that the Universe became denser.
It should be mentioned that the big-bang hypothesis is a widely accepted account of the universe's evolution. Its defining characteristic is the universe's birth from a condition of great heat and density—the so-called big bang, which occurred 13.8 billion years ago.

To solve this problem we will apply the concepts related to the kinematic equations of linear motion. Punctually we will verify the vertical displacement and the horizontal displacement from their respective components. We will start by calculating the time it took to reach the objective and later with that time, we will find the horizontal velocity launch component. The position can be written as,
Here,
h = Height
= Initial velocity in vertical direction
= Vertical acceleration (At this case, due to gravity)
= Time
There is not vertical velocity because the ball was thrown horizontally), then we have that
Now using the equation of horizontal motion we have with this time that the initial velocity was,
Here,
= Horizontal initial velocity
= Time
= Acceleration in horizontal plane
There is not acceleration in horizontal plane, only in vertical plane, then we have
Therefore the pitching speed is 22.5938m/s
0kg
If the gravitational pull is zero and I multiply by mass I get a zero
I would say B but I’m not 100%
