Answer 1

Basically your liquid will go over the line because you are adding more mass. the balloon will inflate because  of mass filling it.  Part 1  I noticed that there was a change from the original line.   part 2  Some mass is lost. The bubbles are the gas leaving. The balloon increases in size because of the mass. The cup got heavier when I added the vinegar.

Gas leaving caused the bubbles.

A 66 kg student stands on a very light, rigid board that rests on a bathroom scale at each end as shown in (Figure 1).

Answers

The reading on the scale is equal to the weight of the student which is 646.8 N.

The given parameters;

mass of the student, m = 66 kg

The reading on the scale is determined by applying Newton's second law of motion as follows;

[tex]R = ma+ mg\\\\R = m(a + g)\\\\R = m(0 + g)\\\\R = mg[/tex]

The student is at rest and not accelerating, a =0

[tex]R = 66 \times 9.8\\\\R = 646.8 \ N[/tex]

Thus, the reading on the scale is equal to the weight of the student which is 646.8 N.

Explanation:

The phrase “seat value” is used in the hospitality and bar sectors to describe how much money each seat or square foot of customer area must generate to justify its existence.

What is the use of seat by the people?

An area to sit is a seat. The phrase may also refer to headquarters in a more general meaning as well as extra elements such a back, armrest, and head restraint.

Being in the centre allows you to benefit from both the advantages of both front and back seating while balancing out their extremes. While you're still close enough to be paying careful attention to the lecture, the middle rows will relieve you of the pressure and expectations of the front.

By remaining seated, students help avoid physical altercations. There is more time spent on task when pupils are seated.

Environmental psychology, which gives people the impression that they have some degree of influence over their daily lives, is the driving force behind all of this behavior.

A 50.0 kg crate is pulled 375 N of force applied to a rope. The crate slides without friction.
After being pulled 3.07 meters the crate has a velocity of 5.61 m/s. What is the angle (degrees) made by the rope with the horizontal?

Answers

Hi there!

We can use the work-energy theorem to solve.

Recall that:

[tex]\large\boxed{W = \Delta KE = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2}[/tex]

The initial kinetic energy is 0 J because the crate begins from rest, so we can plug in the given values for mass and final velocity:

[tex]W = \frac{1}{2}(50)(5.61^2) = 786.8025 J[/tex]

Now, we can define work:

[tex]\large\boxed{W = Fdcos\theta}}[/tex]

Now, plug in the values:

[tex]786.8025 = Fdcos\theta\\\\786.8025 = (375)(3.07)cos\theta[/tex]

Solve for theta:

[tex]cos\theta = .6834\\\theta = cos^{-1}(.6834) = \boxed{46.887^o}[/tex]

explain maximum and minimum thermometer working(answer only for points will be reported)​

Answers

Explanation:

Six’s Maximum and Minimum thermometer is a U shaped parallel tube made up of glass. One side registers the maximum temperature and the other side records the minimum temperature.The bend at the bottom of the thermometer contains mercury which moves up or down based on the expansion and contraction of alcohol.When the temperature rises, the alcohol expands and pushes the mercury up the maximum column. This also pushes the mercury down in the minimum column.Similarly, when the temperature falls, the alcohol contracts and pulls the mercury up in the minimum column resulting in a fall of mercury in the maximum column.The steel indexes are located on the surface of mercury. They move along with the flow of mercury up and down.When the temperature reaches its maximum and minimum limits, the metal indexes remain at that place. This helps in recording the maximum and minimum temperatures of the day.

Question 5. One 1,5V battery runs a portable MP3 player that draws 5,7mA of current
for about six hours before it runs out.
a) What is the resistance If the portable MP3 player?
b) How much power is dissipated in the portable MP3 player?
c) Find the energy delivered by the portable MP3 player?

Answers

First, convert the values of the units to S.I units (otherwise the final answer may be wrong):

P.D = 1.5 volts
Current = 5.7 x 10^-3 amps
Time = 21600 seconds


a) To find resistance, you can use the equation V=IR and rearrange it to find the resistance.

Resistance = p.d / current
Resistance = 1.5 / 5.7x10^-3

Resistance = 263.2 ohms (rounded to 1dp)


b) To find power, you can use the following equations to calculate power:
P=VI
P=I^2 R
P = V^2 / R
P = E/T

You can use any of the equations and still get the right answer, however it's best to use the equations which have the values that you already know from the questions.

I used P=VI:

Power = p.d x current
Power = 1.5 x (5.7x^-3)

Power = 8.55 x 10^-3


c) To find energy, you can use the equation E=PT.

Energy = power x time

(Using the value of power from the previous question)

Energy = (8.55x10^-3) x 21600

Energy = 184.68 joules

Explain how energy changes in the spring toy below when it goes downstairs.

Answers

Given what we know, we can confirm that the spring toy uses the transfer of potential gravitational energy into kinetic energy of motion in order to fall down the stairs.

How does the toy do this?The toy stores potential energy. It does this using gravity. Once it begins to fall, it uses the momentum from each fall to continue to do so. With each fall, its stored potential energy is transferred to kinetic energy.

Therefore, we can confirm that the spring toy uses its position at the top of each stair as a source of potential energy, which using the momentum from the last fall, it transfers into the kinetic energy of motion as it falls, all through the help of gravity.

I will mark brainliest

Answers

Hi there!

Answer E.

For a collision to be completely elastic, there must be NO LOSS in kinetic energy.

We can go through each answer choice:

A. Since the ball rebounds at half the initial speed, there is a loss in kinetic energy. This is NOT an elastic collision.

B. A collision involving sticking is an example of a perfectly INELASTIC collision. This is NOT an elastic collision.

C. A reduced speed indicates that there is a loss of kinetic energy. This is NOT elastic.

D. The balls traveling at half the speed after the collision indicates a loss of kinetic energy, making this collision NOT elastic.

E. This collision indicates an exchange of velocities, characteristic of an elastic collision. We can prove this:

Let:

m = mass of each ball

v = velocity

We have the initial kinetic energy as:

[tex]KE = \frac{1}{2}mv^2 + 0 = \frac{1}{2}mv^2[/tex]

And the final as:

[tex]KE = 0 + \frac{1}{2}mv^2 = \frac{1}{2}mv^2[/tex]

Thus, Kinetic energy is CONSERVED. This collision is ELASTIC.

C. What is an example of an action and reaction at work in this picture? (Use Newton's 3rd Law to help you)

Answers

Answer:

The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.

At point B, Alberto's distance covered increases with time, equal distance is covered in equal time interval. The speed increases uniformly. At the point C to D, the distance covered with time remains the same. At the point D, equal distance is no longer covered in equal time intervals.

According to the law of inertia, an object will remain at rest or in a state of uniform motion unless it is acted upon by an unbalanced force. This means that smokey mouse will continue moving uniformly unless a force acts on it.

From Newton's second law; F = ma and a = F/m. F = force , m= mass, a = acceleration. This implies that smokey mouse can increase its speed by;

Increasing the force acting on the mouse

Decreasing the mass of the mouse

Action and reaction is encountered as the mouse is walking. The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.

The distance covered as the crane does work is 76 m.

Recall that the work done in lifting the crane is the product of force and distance covered. In this case, we are talking about the distance through which the crane is raised. Therefore;

Work done = Fs

F = Force applied

s = Distance covered

Work done/Force applied = Distance covered
