<h3><u>Answer;</u></h3>
B. 3.43 kPa
<h3><u>Explanation</u>;</h3>
Pressure is given by the formula;
Pressure = Force / Area
Force is the product of mass and acceleration due to gravity.
Thus; Force = mass x acceleration due to gravity
Substituting;
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, using the first equation;
Pressure = 3430 N / 1m² or Pa
<h3> <u>= 3.43 kPa</u></h3>
Before 7 after 9. A pH smaller than 7 indicates acidity with 0 being completely acidic. A pH greater than 7 shows alkalinity with 14 being completely alkaline. 7 is neutral. Since NaOH is alkaline, adding it to a neutral substance would increase the pH and it would increase from 7 to 9.
So far, I have not been able to run a mile in under 30 minutes.
That proves that I can't do it, but <span>that does not necessarily mean
its impossible. It </span>doesn't prove that nobody else can do it.
Nobody and nothing has ever traveled faster than the speed of light.
That doesn't prove that somebody or something that hasn't tried yet
can't do it. But discoveries in Physics, Quantum Mechanics, Cosmology,
and Relativity, over roughly the past 125 years, which explain and predict
almost everything seen in hundreds of experiments and thousands of
observations since then, do all agree that the speed of light is, let's say,
nature's "speed limit", and that no matter how hard you try, nothing and
nobody CAN travel faster.
Answer:
D.Tetrahedral
Explanation:
The central atom has 0 lone pair and 4 bond pairs. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
According to VSEPR theory, each molecule arranges itself such that it faces minimum repulsion and the given molecule is of type
.
Therefore the answer will be D.
D.Tetrahedral
The ball is moving 60 mph from the observers POV because the ball already has a speed of 50mph and the man is able to throw it at a speed of 10mph
and when you add 50mph and 10mph = 60mph.
