What happens at the anode of an electrolytic cell?a. electrons are given up
c. electrons are formed
b. electrons are accepted
d. electrons form bonds

Answers

Answer 1
Answer: The correct answer for the question that is being presented above is this one: "c. electrons are formed." The anode inside the electrolytic cell makes the electrons formed. There is something happened inside the electrolytic cell that will make the electrons to form.

For an isothermal process, the work done by or on a system of ideal gas is equal to the change in what? A. The work done is equal to the change in internal energy.
B.The work done is equal to the change in heat energy.
C.The work done is equal to change in entropy.
D.The work done is equal to the change in pressure.

Answers

For an isothermal process, the work done by or on a system of ideal gas is equal to the change in heat energy. The correct option is B.

What is isothermal process?

The process in which the temperature remains constant and other physical quantities are variable, is called the isothermal process.

From the first law of thermodynamics, the work done is the difference between heat supplied and change in internal energy of the system.

W = ΔQ - ΔU

For isothermal process, change in internal energy will be zero.

So, work done is equal to  the change in heat energy.

Thus, the correct option is B.

Ocean waves are examples of:
transverse waves
longitudinal waves
circular waves

Answers

Circular is correct.
ocean waves could be the example of both circular and transverse waves. sometimes, ocean waves could move in an up and down (~~~~~~~) wave. sometimes the ocean waves could move in circular waves, [((((O))))] so it depends on the movement. I would mostly choose transverse waves, though, since most of the time, 'ocean waves' are meant to be such kind of movement [~~~~~~~~~~~~~~].

In 3.0 seconds, a wave generator produces 15 pulses that spread over a distance of 45 centimeters. Calculate its period.0.022 s

0.066 s

0.20 s

0.33 s

Answers

Period = (time) / (number of pulses)

= (3 sec) / (15 pulses)

= 0.2 sec/pulse

Think about multiplying the mass of each student by a factor to calculate each student’s kinetic energy. Is there a common factor that works for every student? If so, what’s this factor?

Answers

Answer:

KE= (1/2)mv^2

given m, the remaining components of the equation are=

1/2v^2?

Explanation:

KE= (1/2)mv^2

plug in...

=(1/2)(27 kg)(3 m/s)^2= 121.5

KE= 121.5 J

Answer:

Multiplying the mass of any student by a factor of 4.5 gives the kinetic energy of the student.

How are mass and inertia related

Answers

inertia is the resistance of any physical object to any change in its state of motion. inertia exists due to the mass of the object

3. Reading the graph, we find the velocity is 8 m/s at t-2 s and 16 m/s at t-4 s. Based on this information,what is the acceleration?

Answers

first take the change in time, which is the difference of 4 & 2, so 2 and that’s that’s denominator, then take the change in velocity, which is the difference of 16 and 8, which is 8 ( ur numerator)


8 / 2 = 4 so ur acceleration should be 4
