<h3><u>Answer;</u></h3>
Energy
<h3><u>Explanation;</u></h3>
- A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
- <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
- <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
- <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.
pH is the measure of the concentration of hydrogen ions in a solution
Given:
m = 0.240 kg = 240 g, the mass of O₂
V = 3.10 L = 3.10 x 10⁻³ m³, the volume
Because the molar mass of oxygen is 16, the number of moles of O₂ is
n = (240 g)/(2*16 g/mol) = 7.5 mol
As an ideal gas,
p*V = nRT
or
V = (nRT)/p
where R = 8.314 J/(mol-K)
When
p = 0.910 atm = (0.910 atm) * (101325Pa/atm) = 92205.75 Pa
T = 27 °C = (27 + 273) K = 300 K
then the volume is

V = (0.2029 m³)*(10³ L/m³) = 202.9 L
Answer: 203 liters
Answer:
4.3 * 10 N
Explanation:
To calculate torque, we multiply the distance from the pivot by the perpendicular (the part of the force that acts at right angles to the displacement vector) component of the force to the displacement vector from the pivot.
torque = distance from pivot * perpendicular force
170 Nm= 0.4 m * F
F = 425 N = 4.3 * 10 N rounded off to two significant figures
The valence electrons are the one furthest from the nucleus
