Answer:

(I will talk in my opinion only)

electronics do harm our mental health but they are also helpful ones like mobile both a boon and a curse

physical health is greatly affected and it's something no need to explain

social ( for me ) my only place to be social and talk people is brainly so for me mobile is very important

Answer:

Just a little bit. You should not be on electronics all the time. I know some people that are so addicted to there electronics that they won't even hang out with people. If you are at the point where you think about things other than school, friends, and family...you should think about getting off of your electronics and go play with a neighborhood friend outside, or have a sleepover! Your whole life should not count on your phone, iPad, or your laptop.

Answer:

The carbon atom has greater kinetic energy than a hydrogen atom.

Hope this helps! :)

Carbon atom has the greater kinetic energy.

Kinetic energy is defined as the energy attained by a body by virtue of its motion.

Here,

The speed of the hydrogen atom and carbon atom are the same.

Kinetic energy of hydrogen atom, KEн = 1/2 m(н) v(н)²

Kinetic energy of carbon atom, KEс = 1/2 m(с) v(с)²

where m and v are mass and speed respectively.

Taking the ratio,

KEн/KEс = m(н)/m(с)

KEн/KEс = 2/12

KEн/KEс = 1/6

KEс = 6KEн

Therefore the kinetic energy of carbon atom is 6 times the kinetic energy of hydrogen atom.

Hence,

Carbon atom has the greater kinetic energy.

Answer:

Q=mc(T2-T1)

Explanation:

Ti is the temperature

m is mass

c is specific heat capacity for steam

Q is heat, [Q]=J

Answer:

100 m/s

Explanation:

We'll begin by converting 1 km to m. This can be obtained as follow:

1 km = 1000 m

Finally, we shall determine the final velocity of the car. This can be obtained as follow:

Initial velocity (u) = 0 m/s

Acceleration (a) = 5.0 m/s²

Distance (s) = 1000 m

Final velocity (v) =?

v² = u² + 2as

v² = 0² + (2 × 5 × 1000)

v² = 0 + 10000

v² = 10000

Take the square root of both side

v = √10000

v = 100 m/s

Therefore, the speed value of the car is 100 m/s.

Answer:

Many species will be affected by increased global temperatures due to following reasons as mentioned.

As snow at poles will continue to melt and habitat for many species will be lost. This is create imbalance in the food chain of oceans which are prime source of food for many species. Some species will thrive as their hunters will be eradicated due to loss of habitat and overall food chain balance will be disturbed. This will cause species to go extinct.

The cycle of rain will be disturbed causing an imbalance in water cycle which will cause droughts and species will suffer and die eventually will go extinct.

(1) Use Newton's second law: The force F required to accelerate a mass m with acceleration a satisfies

F = m a

So the force needed to accelerate the lion-stretcher system is

F = (175 kg) (2 m/s²) = 350 N

(2) Average speed is defined as the ratio of distance traveled to the time it takes to travel that distance, so in this case the bus's average speed is

(280 km) / (4 h) = 70 km/h

(3) The vertical lines in the plot split up the distance function into 5-minute chunks. The one with the highest average speed is the one over which the distance changes the most. Roughly, the average speeds over each of the given choices is

• 0 to 5 min : (1500 m - 0 m) / (5 min) = 300 m/min

• 10 to 15 min : (3250 m - 2500 m) / (5 min) = 150 m/min

• 15 to 20 min : (3750 m - 3250 m) / (5 min) = 100 m/min

• 25 to 30 min : (4500 m - 4250 m) / (5 min) = 50 m/min

(4) Velocity is a vector, so it has both magnitude and direction. A car moving at constant velocity would be traveling at the same magnitude and direction. But a car on the circular track is constantly turning and changing direction.

Answer:

The ratio of the width of the slits to the separation between them is 1:5

Explanation:

For this set of question

n = 1, m = 5

As we know for nth minimum

[tex]D sin\theta =n \lambda[/tex]

For mth Maximum

[tex]d sin\theta =m \lambda[/tex]

From the above two equations we get

[tex]Sin\theta = \frac{1*\lambda}{D} \\d * \frac{1*\lambda}{D} = 5 *\lambda\\\frac{D}{d} = \frac{1}{5}[/tex]

The ratio of the width of the slits to the separation between them is 1:5

Answer:

Average acceleration of the car is 1.167 m/s^2

Explanation:

The speed of car with which it is travelling is 12 m/s

As the driver accelerates the car, the speed reaches 26 m/s

The change in speed in 12 seconds is

26 -12 = 14 m/s

Average acceleration is change in speed divided by time

[tex]\frac{14}{12} \\1.167[/tex] m/s^2

Answer:

Average Density = 1.07 g/cm³

Explanation:

The average density of the whole mixture is given by the following formula:

[tex]Average\ Density = \frac{mass\ of\ whole\ mixture}{volume\ of\ whole\ mixture}[/tex]

where,

volume of whole mixture = volume of water + volume of acid

volume of whole mixture = 100 cm³ + 50 cm³ = 150cm³

mass of whole mixture = mass of water + mass of acid

mass of whole mixture = (volume of water)(density of water) + (volume of acid)(density of acid)

mass of whole mixture = (100 cm³)(1 g/cm³) + (50 cm³)(1.2 g/cm³)

mass of whole mixture = 160 g

Therefore,

[tex]Average\ Density = \frac{160\ g}{150\ cm^3}[/tex]

Average Density = 1.07 g/cm³
