It is b 9.1 :) have a nice day
The true statement according to Newton's laws of motion is; "there is no net force on the block during the 2nd second as zero net force keeps the motion constant."
According to the Newton first law of motion, an object will continue in its state of rest or uniform motion unless it is acted upon by a net force. The action of a net force leads to an acceleration.
In the 2nd second of the journey, there is no net force on the block hence the block continues to move at constant velocity.

The ideal gas constant is a proportionality constant that is added to the ideal gas law to account for pressure (P), volume (V), moles of gas (n), and temperature (T) (R). R, the global gas constant, is 8.314 J/K-1 mol-1.
According to the Ideal Gas Law, a gas's pressure, volume, and temperature may all be compared based on its density or mole value.
The Ideal Gas Law has two fundamental formulas.
PV = nRT, PM = dRT.
P = Atmospheric Pressure
V = Liters of Volume
n = Present Gas Mole Number
R = 0.0821atmLmoL K, the Ideal Gas Law Constant.
T = Kelvin-degree temperature
M stands for Molar Mass of the Gas in grams Mol d for Gas Density in gL.

<span>Hormones are really important to bone strength. Hormones are chemicals made by glands that travel throughout the body and have many effects on growth, maturation, energy, weight, and bone strength. Sex hormones (estrogen made in the ovary of females and testosterone made by the testes in males) control ability to reproduce. They also are a major reason that bone strength increases in the early teenage years. When teenagers have low estrogen or testosterone levels, the bone becomes weaker.</span>
