Answer:

Hello! The answer is D or X, Z, Y, W

Explanation:

Well to work out kinetic energy, you need to use the formula:

(1/2 * mass) * velocity^2 = Kinetic Energy (Joules)

W = (1/2 * 10) * 8m/s^2 = 320 J

X = (1/2 * 18) * 3m/s^2 = 81 J

Y = (1/2 * 14) * 6m/s^2 = 252 J

Z = (1/2 * 30) * 4m/s^2 = 240 J

If you put those in order, you get X, Z, Y, W, which is option D.

A certain first-order reaction is 58% complete in 95 s. What are the values of the rate constant and the half-life for this proc

guajiro [1.7K]

Answer:

$0.005734 s^{-1}$ and 20.86 seconds are the values of the rate constant and the half-life for this process respectively..

Explanation:

Expression for rate law for first order kinetics is given by:

$a_o=a\times e^{-kt}$

where,

k = rate constant

t = age of sample

$a_o$ = let initial amount of the reactant

a = amount left after decay process

We have :

$a_o=x$

$a=58\%\times x=0.58x$

t = 95 s

$0.58x=x\times e^{-k\times 95 s}$

$\k= 0.005734 s^{-1}$

Half life is given by for first order kinetics::

$t_{1/2}=\frac{0.693}{k}$

$=\frac{0.693}{0.005734 s^{-1}}=120.86 s$

$0.005734 s^{-1}$ and 20.86 seconds are the values of the rate constant and the half-life for this process respectively..

Reading the temperature of a solution by using a thermometer is an example of a(n) ________.

blsea [12.9K]

Answer:

B. Observation

Explanation:

Using a thermometer to read the temperature of a solution is tantamount to the making an observation.

Observation are recorded using our senses of sight, taste, earing, feeling etc or by the use of instrument.

Through observation, data is usually collected to make inferences about an experiment.
An observation leads to the formulation of a hypothesis which is scientific guess that leads to experimental designs.
Conclusions are drawn from the information of data obtained from an experiment.
