Answer:

B. 2

Explanation:

The reaction expression is given as:

_S + 3O₂ → 2SO₃

Now let us balanced the expression;

On the product side we have 2 moles of S

On the reactant side we should have 2moles of S

So, we put the coefficient 2 to balance the expression;

We have 6 moles oxygen on both sides

Helen [10]

The percentage error in his experimental value is -51.97%.

<h3>What is percentage error?</h3>

This is the ratio of the error to the actual measurement, expressed in percentage.

To calculate the percentage error of the student, we use the formula below.

Formula:

Error(%) = (calculated value-accepted value)100/(accepted............. Equation 1

From the question,

Given:

Calculated value = 4.15 g/cm
accepted value = 8.64 g/cm

Substitute these values into equation 1

Error(%) = (4.15-8.64)100/8.64
Error(%) = -4.49(100)/8.64
Error(%) = -449/8.64
Error(%) = -51.97 %

Hence, The percentage error in his experimental value is -51.97%.

A box slides down a 31° ramp with an acceleration of 0.99 m/s2. Determine the coefficient of kinetic friction between the box an

tino4ka555 [31]

Answer: $\mu$ =0.48

Explanation:

Given

inclination $\theta =31^{\circ}$

Acceleration of object $=0.99 m/s^2$

Now using FBD

$mg\sin \theta -f_r=ma$

$mg\sin \theta -\mu mg\cos \theta =ma$

$a=g\sin \theta -\mu g\cos \theta$

$0.99=5.04-\mu 8.4$

$\mu 8.4=4.057$

$\mu =0.48$

if the amplitude of sine curve is 4 and the frequency is 1 with no phase shift, what is the function that descirbes this curve?

Vlada [557]

Answer:

y = 4 Sin (2πt)

Explanation:

Amplitude, A = 4

frequency, f = 1

Wave function is given by

y = A sinωt

where, ω is angular frequency

ω = 2 π f = 2 π x 1 = 2π

So, the desired wave function

y = 4 Sin (2πt)
