You're describing an increase in the object's kinetic energy, which depends
on speed, and no change in its potential energy, which depends on height.

how many days does it take a team of drivers to drive a truck california and back to lansing if the drivers average 15m/s includ
Scilla [17]

Answer:

t = 2.2 [days] and is there is a round trip, it will be double time t = 4.4 [days]

Explanation:

First, we need to arrange the problem to work in the same unit system (SI).

We need to convert the 1800 [miles] to meters, therefore:

1800[miles] * \frac{1609.34[m]}{1[mile]} }=2896812[m] = 2896.8[km]

Now using the following equation of kinematics, for the avarage velocity  we have:

v=\frac{x}{t} \\where \\v=velocity [m/s]\\t = time [s]\\x=distance traveled [m]\\

therefore:

t=\frac{x}{v} \\t=\frac{2896812}{15}\\ t=193120.8[s]

Now we can convert from seconds into days.

193120.8[s]*\frac{1[hr]}{3600[s]}*\frac{1[day]}{24[hr]}\\  t = 2.2[days]

Now if the truck has the need to come back, the team will spend double time.

t= 4.4 [days]

Would an increase in pressure favor the formation of ozone or of oxygen?
max2010maxim [7]
<h3><u>Answer;</u></h3>

<u>An increase in pressure favors the formation of ozone </u>

<h3><u>Explanation;</u></h3>
  • Ozone, O3, decomposes to molecular oxygen in the stratosphere according to the reaction

2O3(g) ⇆ 3O2 (g).

  • There are more moles of product gas than moles of reactant gas. An increase in total pressure increases the partial pressure of each gas, shifting the equilibrium towards the reactants.
  • Therefore; an increase in pressure favors backward reactions towards the formation of ozone.

A diamond with a mass of 45 g hangs motionless from a chain. what is the upward force of the chain on the diamond?
BARSIC [14]
The upward force of the chain on the diamond would be the tension in the chain, and this tension would have to support the weight of the 45g that hangs from the chain.

mass = 45 g = 45/1000 kg = 0.045kg

Weight = mg = 0.045 * 10 ≈ 0.45N,            g ≈ 10 m/s²

So the upward force is ≈ 0.45N.
