Explanation:

sample answer

The plants can be used in the future to help counteract some human

emissions they absorb carbon dioxide from the air and release oxygen.

What is photosynthesis?

It is a process carried out by photosynthetic autotrophic organisms, such as plants, algae and some prokaryotes. These organisms capture sunlight, convert it into chemical energy, which will be used to produce organic compounds, based on water and carbon dioxide.

Trees, like other plants, in the process called photosynthesis, absorb carbon dioxide from the air and release oxygen. They also make the air wetter and cooler. In this way, plants contribute to the good quality of the air we breathe.

A measuring cylinder contains 80 cm3 of a certain liquid. The liquid is poured

into an empty beaker of mass 48 g. The total mass of the beaker and the liquid

was found to be 136 g.

(a) Calculate the mass of the liquid in grams.

(b)Calculate the density of the liquid in gcm-3

Answers

Answer:

1.5 g/cm

Let d be the density of fluid.

So , Initial reading of balance, F

1

=30dg N

After the level reaches 50cm

Final reading of balance , F

2

=50dg N

Given that difference between final and initial reading is 30g

i.e, F

=30 g

⟹50dg−30dg=30g

⟹20dg=30g

⟹d=

So, density of fluid is 1.5g/cm

A vinyl "record" with a diameter of 0.3 m is spinning at a rate of 1 m/s.

a) What would the centripetal acceleration be for a piece of gum (0.005kg) stuck to the outside edge of the record?

b) How much centripetal force will the gum have to overcome to remain "stuck" to the vinyl?​

Answers

This question involves the concepts of centripetal force and centripetal acceleration.

a) The centripetal acceleration for the piece of gum stuck to the outside edge of the record will be "6.67 m/s²".

b) The gum will have to overcome "0.033 N" centripetal force to remain stuck to the vinyl.

a)

The centripetal acceleration of the gum can be found using the following formula:

[tex]a_c=\frac{v^2}{r}[/tex]

where,

[tex]a_c[/tex] = centripetal acceleration = ?

v = linear speed of record = 1 m/s

r = radius of the record = [tex]\frac{diameter}{2}=\frac{0.3\ m}{2}=0.15\ m[/tex]

Therefore,

[tex]a_c=\frac{(1\ m/s)^2}{0.15\ m}\\\\a_c = 6.67\ m/s^2[/tex]

b)

Now, the centripetal force can be given as follows:

[tex]F_c=ma_c\\F_c=(0.005\ kg)(6.67\ m/s^2)\\F_c=0.033\ N[/tex]

What is the potential energy of a 2 kg bowling ball resting at the top of a 5 m high hill? Show all of your work and include the correct units to receive full credit.​

Answers

Answer:

[tex]\boxed {\boxed {\sf 98 \ J}}[/tex]

Explanation:

We are asked to find the potential energy of a bowling ball.

Potential energy is the energy an object possesses due to its position. It is calculated using the following formula.

[tex]E_p= mgh[/tex]

In this formula, m is the mass, g is the acceleration due to gravity, and h is the height.

The bowling ball has a mass of 2 kilograms. The hill is 5 meters high. Assuming this situation is occurring on Earth, the acceleration due to gravity is 9.8 meters per second squared.

m= 2 kg g= 9.8 m/s²h= 5 m

Substitute the values into the formula.

[tex]E_p= (2 \ kg )(9.8 \ m/s^2)(5 \ m)[/tex]

Multiply the numbers together.

[tex]E_p=19.6 \ kg*m/s^2(5 \ m)[/tex]

[tex]E_p=98 \ kg*m^2/s^2[/tex]

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. Our answer of 98 kg*m²/s² is equal to 98 Joules.

[tex]E_p= 98 \ J[/tex]

The bowling ball has 98 Joules of potential energy.

A cyclist pedals up to the top of a hill.

a) What kind of energy is being used to do work against gravity?

b) State the type of energy the cyclist has when he stops at the top of the hill.

c) When the cyclist moves downhill without pedaling, what type of energy does he gain?

Answers

Explanation:

A) kinetic energy

B) potential energy

C) Mechanical energy

a) The motorcyclist rises utilising chemical energy's "mechanical energy" (kinetic and potential energy). b) The cyclist's highest "gravitational potential energy" is transformed into motion downhill. c) When the rider moves downhill, potential energy becomes "kinetic energy." "Kinetic energy" is most vital.

a) "Mechanical energy" is used by the cyclist to ride up the slope. Kinetic and potential energy from an object's motion and position make up mechanical energy. As they pedal, cyclists transform chemical energy from their bodies into mechanical energy. This mechanical energy overcomes gravity as the cyclist climbs. As the cyclist climbs, potential energy accumulates, which is translated into kinetic energy as they descend.

b) At the summit of the slope, the biker has "gravitational potential energy." An object's gravitational potential energy depends on its position in a gravitational field. The biker has gained potential energy by climbing against gravity. At the crest of the hill, the cyclist's kinetic energy is lowest while potential energy is highest. The cyclist's potential energy is ready to be turned into kinetic energy as they descend.

c) Without pedalling, the rider gains "kinetic energy." The cyclist's speed increases as they descend, converting potential energy into kinetic energy. The cyclist's potential energy is turned into kinetic energy by gravity. As the rider descends, their potential energy diminishes but their kinetic energy increases, speeding up their bike. The biker converts potential energy into kinetic energy as he descends, and most of it is converted back at the bottom.

In conclusion, the cyclist climbs the incline using "mechanical energy" from chemical energy. They descend using "gravitational potential energy" at the top. Potential energy becomes "kinetic energy" when the rider descends without pedalling, speeding up the bike. Potential-to-kinetic energy conversion helps the cyclist climb the slope.

We do not feel the gravitational forces from objects other than the Earth because they are weak.

Answer:

We do. It's just way too small compared to the force between the objects we're observing and the earth. It's like looking inside a room with an elephant and a grain of rice. The rice is there, it's just too small compared to the room and the elephant inside for you to notice it.
