What is the situation when I might travel high velocity but low acceleration

Anna007 [38]

Cruising at 35,000 feet in an airliner, straight toward the east,
at 500 miles per hour.

Since your speed is not changing and you're moving in a straight line,
your acceleration is zero.

A compound decomposes by a first-order process. if 25.0% of the compound decomposes in 60.0 minutes, the half-life of the compou

Tom [10]

Answer:d. 145 minutes

Half-life is the time needed for a radioactive to decay half of its weight. The formula to find the half-life would be:

Nt= N0 (1/2)^ t/h

Nt= the final mass
N0= the initial mass
t= time passed
h= half-life

If 25.0% of the compound decomposes that means the final mass would be 75% of initial mass. Then the half-live for the compound would be:
Nt= N0 (1/2)^ t/h
75%= 100% * (1/2)^ (60min/h)
3/4= 1/2^(60min/h)
log2 3/4 = log2 1/2^(60min/h)
0.41503749928 = -60min/h
h= -60 min / 0.41503749928= 144.6min

Which equation is used to help form the combined gas law? mc009-1. Jpg mc009-2. Jpg mc009-3. Jpg mc009-4. Jpg.

Luba_88 [7]

The combined gas law equation has been $\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$ .

The combined gas law has been assigned to the ideal gas. It has been stating that ideal gas are having negligible inter-molecular attraction and collision resulting in the absence of pressure and volume from the particles.

In an ideal gas the equation has been given as:

$PV=nRT$

Where, P has been the pressure of the gas

V has been the volume of the gas

n has been the moles of the gas

R has been a constant

T has been the temperature of the gas

The combined gas law has been given as the change in the pressure, and volume for a gas. It has been given as:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$
