As the speed increases and the pressure decreases
The answer would be Newton’s Second Law
Answer:
Explanation:
Given
ambient Pressure =98.10 kPa
(a)gauge pressure 152 kPa
we know
Absolute pressure=gauge pressure+Vacuum Pressure
=152+98.10=250.1 kPa or 36.27 psi
(b)
=67.5 Torr or 8.99 kpa
as 1 Torr is 0.133 kPa
=8.99+98.10=107.09 kPa or 15.53 psi
(c)
=0.1 bar or 10 kPa
Thus absolute pressure=98.10-10=88.10 kPa or 12.77 psi
as 1 kPa is equal to 0.145 psi
(d)=0.84 atm or 85.113 kPa
as 1 atm is equal to 101.325 kPa
=98.10-85.11=12.99 kPa or 1.88 psi
The weight (W) of an object is the product of its mass (m) and the acceleration (a). That is,
W = m x a
Substituting the known values give,
W = (60 kg) x (3.75 m/s²) = 225 N
Thus, the object's weight is 225 N. The answer is letter D.
The reactivity of a nonmetal element in period 2 would be more violent than an element in period 4, as the size of the element and its ability to gain electrons would decrease as you go down the group in the table. Nonmetals want to form negative ions, as their weak valence shell allows them to gain electrons from other elements.
From the information gathered, the answer is '<span>The period 2 element would be more reactive because the attractive force of protons is stronger when electrons are attracted to a closer electron shell'. </span>
