Answer:
Electronegativity is a chemical property at the top of the periodic table
Explanation:
electronegativity is a chemical property that measures the ability of an atom to attract a bonding pair of electrons when it is part of a compound
it's a property of atom that increases as you go to the right and up.
One example is the Pauling scale. it is a numerical scale of electronegativities. It was first developed by Linus Pauling.
it is commonly used to calculate the ability of electronegativity to attract electrons to itself.
The most common electronegative element is Flourine, having an assigned value of 4.0, ranging down to caesium and francium, having the least electronegative at 0.7
The Ammeter is used to detect and measure current or amperage. Also a more common tool now used is a multimeter that detects and measures voltage, current, and resistance.
Any questions please just ask. Thank you.
Crushing pressure. Human bodies are used to air pressure. The air pressure in our lungs, ears and stomachs is the same as the air pressure outside of our bodies, which ensures that we don't get crushed. Our bodies are also flexible enough to cope when the internal and external pressures aren't exactly the same.
Answer:
Explanation:
Potential energy, which is the energy a body assumes at a position, can be calculated using the formula:
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (m)
Answer:
Explanation:
The momentum of the first piece = m v =- m x 31 i kg m/s in - x direction direction
The momentum of the second piece = -m x 31 j kg m /s in Y - direction
Total momentum = - 31 m( i + j )
To conserve momentum , the third piece must have momentum equal to this
and opposite to it
So momentum of the third piece = 3m x V = 31 m ( i +j )
V = 31/3 ( i + j ) =
Magnitude of velocity V = √2 x 31/ 3 = 14.6 m / s
Its direction will be towards the vector i + j ie 45° from x - axis in positive direction
