A 30 g spoon is lifted above a table and has 0.062 J of potential energy. How high is it?

Answers

Hi there!

We know that:

U (Potential energy) = mgh

We are given the potential energy, so we can rearrange to solve for h (height):

U/mg = h

g = 9.81 m/s²

m = 30 g ⇒ 0.03 kg

0.062/(0.03 · 9.81) = 0.211 m

if a balloon is squeezed, what happens to the pressure of the gas inside the balloon?

Answers

Answer:   By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases. If the volume increases, its pressure decreases.

b. The molar mass of the compound is 116 g/mol, what is its molecular formula?

PLS URGENTLY ANS

Answers

The empirical formula of the compound is Li₂CO₃

First, we will determine the respective number of moles of each element present in the compound by dividing by their atomic masses

Lithium                      Carbon                          Oxygen

6.25÷6.94                 5.40÷12.01                    21.60÷16.00

0.9006                      0.4496                          1.35

Now, divide through by the smallest number of moles, that is, 0.4496

Lithium                      Carbon                          Oxygen

0.9006÷0.4496        0.4496÷0.4496            1.35÷0.4496

2                                      1                                    3

Hence, the empirical formula of the compound is Li₂CO₃

Define power and explain how to determine power. (4 points)

Answers

The definition of power is operating electrically or having strength or force. An example of power is the functioning of a gasoline-driven saw or tool. Or Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the traction force on the wheels and the velocity of the vehicle. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element.

A cliff diver dove off a cliff at 8 m/s and landed in the water 21 m away from the cliff. How high is the cliff?

Answers

The vertical height of the cliff on which the diver drove off is 33.76 m.

The given parameters;

horizontal velocity of the diver, v = 8 m/shorizontal distance traveled by the diver, X = 21

The time of motion of the cliff diver is calculated as follows;

[tex]t = \frac{X}{v} \\\\t = \frac{21}{8} \\\\t = 2.625 \ s[/tex]

The vertical height of the cliff is calculated as follows;

[tex]h = v_0_y t + \frac{1}{2} gt^2\\\\h = 0 + 0.5 \times 9.8 \times 2.625^2\\\\h = 33.76 \ m[/tex]

Thus, the vertical height of the cliff on which the diver drove off is 33.76 m.

Photosynthesis is a process in which green plants manufacture there own food in the presence of sunlight through the equation below

6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂

From the equation above, it can be seen that aside from the food (C₆H₁₂O₆) produced by green plants during photosynthesis, science has assisted us in knowing that these green plants take-up the carbon dioxide (CO₂) that is exhaled by humans and release the oxygen (O₂) that is inhaled by humans thereby purifying the air of the surrounding they are found. This concept has made man understand the importance of planting in residential areas.

Depletion of the Ozone layer; the ozone layer is a layer in the earth stratosphere which shields the earth from direct sunlight/rays. Over the years, the burning of hydrocarbon on earth has caused the depletion of this layer thereby exposing the earth to more direct sunlight from the sun. Science has had an impact in the thinking of man in this regard by making us more conscious of the risk of burning these hydrocarbons which has led to the collective efforts by governments across the world to minimize the burning of these substances.

Rain; rain are droplets of water that fall from the atmosphere. Rain formation occurs when water (in the form of ocean, river and/or seas) are evaporated into the atmosphere as a result of heat from the sun. These evaporated water molecule rises and cools down to form and form a cloud It is then returned to earth in the form of rain. This explanation changes the mythical understanding of rain in different culture

for rogue waves to form so often, they must follow a non linear system, instead of the linear constructive interference system scientists once thought it was to explain these waves. What does it mean to be a non linear equation?

Answers

Rogue waves are unpredictable and sudden waves that appear as surface waves and that have the ability to make ships capsize. For a wave to be a non-linear equation it means that it is unpredictable. What is expected does not actually happen. The resulting wave is often chaotic in nature.

In mathematics, a non-linear equation is one in which the input does not equal the output. This makes it more difficult to predict the outcome of variables.

Also, a linear constructive interference system is one in which the meeting of two waves causes an amplification in which the resulting wave is equal to the sum of the individual waves.

So, when rogue waves are said to be non-linear, it means that the resulting wave is not equal to the individual waves that formed it. They are chaotic and unpredictable.

In an experiment to determine the density of a substance the following results were
obtained. Use the results to plot a graph of mass against volume.
Mass (g) 10 20 30 40 50 60 70 80 90
Volume (cm 3 ) 0.5 1.0 1.4 2.0 2.2 2.6 3.0 3.6 4.5

a) Find the gradient of the graph.
b) What does the gradient represent?
c) What is the mass when the volume is 1.5cm 3 ?
d) What is the volume when the mass is 65g?

Answers

Answer:

a) Gradient = rise/run = mass/volume

since the graph is mass against volume we know mass is on the y-axis and volume is on the x-axis

in physics it’s best to use a larger part of the graph to find the gradient, so imma use the biggest values.

90/4.5 = 20

(additional note: sometimes you may get a different gradient. For example, when using 30 and 1.4 you get ≈21 this is an anomalous result since ita gradient differs; a mass against volume graph is supposed to be linear)

b) gradient represents density (p) since gradient is = mass/volume. And density also = mass/volume

For c and d just plot the points and you’ll be able to read from the graph to get the values.

I got this graph (the image)

but you’ll be able to interpret better when ‘you’ draw it (so try plotting it)
