Answer:

Harish went 1.92 Km in 2 minutes.

Explanation:

Harish is running at 16 m/s (Meters per second) and we need to find how far he goes in 2 minutes.

We can use this formula to calulate the distance:

m/s x time

We know that Harish is going 16m/s so let's plug that in:

16 (m/s) x time

We also should know that 2 minutes is 120 seconds - Let's plug that in too:

16 (m/s) x 120 (Seconds)

Now we calculate:

16 x 120 = 1920

Harish went 1,920 meters in 2 minutes.

Even though we have a correct answer, we can still make it easier to read by converting meters into kilometers.

1 Kilometer (Km) is equal to 1,000 meters.

All we need to do now is divide 1,920 by 1,000 and that will gove us our simplified answer of:

1.92 Km

Answer:

1.92 km

Explanation:

I will explain you:

2×60=120

we have to take 16×120=1920km bro

Answer:

In terms of the light spectrum, blue is a primary color, which means that it is one of the base colors that exist in the universe and it cannot be created by combining different colors together. The primary pigment colors are cyan, magenta, and yellow. Cyan absorbs red, yellow absorbs blue, and magenta absorbs green.

Answer:

2 ans : the bell has 8550 J energy

Answer:

1. kinetic energy = ½mv²

m= 2.1 kg

v = 30m/s

Ek = ½ ×2.1×30×30

= 945J

2. potential energy = mgh

m = 190kg

g = 9.8

h = 45m

Ep = 190×9.8 × 45

= 83790J

3.potential energy = mgh

m= 75kg

g= 9.8

h = 300m

Ep = 75×9.8×300

= 220,500J

Answer:

Aceleracion = 5 m/s²

Explanation:

Dados los siguientes datos;

Velocidad inicial = 10 m/s

Velocidad final = 70 m/s

Tiempo, t = 12 segundos

Para encontrar la aceleración;

Aceleración se puede definir como la tasa de cambio de la velocidad de un objeto con respecto al tiempo.

Esto simplemente significa que la aceleración viene dada por la resta de la velocidad inicial de la velocidad final a lo largo del tiempo.

Por lo tanto, si restamos la velocidad inicial de la velocidad final y la dividimos por el tiempo, podemos calcular la aceleración de un objeto. Matemáticamente, la aceleración viene dada por la fórmula;

[tex] Aceleracion = \frac{final \; velocidad - inicial \; velocidad}{tiempo}[/tex]

Sustituyendo en la fórmula, tenemos;

[tex] Aceleracion = \frac{70 - 10}{12}[/tex]

[tex] Aceleracion = \frac{60}{12}[/tex]

Aceleracion = 5 m/s²

Answer:

Fission and Fusion

Explanation:

There are two basic processes: fission and fusion. In both processes, mass is converted to energy according to the famous equation, e=mc2

In fission, heavy fuel (isotopes of uranium, plutonium, thorium, etc.) atoms split, releasing kinetic energy daughter particles and as radiation. In a reactor plant kinetic energy of the daughter particles is converted to thermal energy as the particles are slowed by the fuel matrix or primary coolant. Radiation is absorbed by various components of the reactor and converted to thermal energy. Thermal energy from both sources is then carried out of the reactor core by primary coolant to a turbine where it is converted to electrical energy which is then transmitted to the power grid.

In fusion, light atoms of hydrogen combine to form helium. Energy released from this reaction will be captured and used to generate electricity as well, once we have constructed a fusion reactor large enough to be self-sustaining (i.e. produce as much or more energy from fusion than needed to start the reaction going).

In the case of nuclear weapons, the tremendous energy from the nearly simultaneous fission/fusion reactions is used to create a fireball, intense radiation, and a large shock wave.

Answer:As a pendulum swings, its potential energy converts to kinetic and back to potential. ... A swinging pendulum.

Explanation:During the course of a swing from left to right, potential energy is converted into kinetic energy and back.

Answer:

The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.

Complete question is;

Lamar writes several equations trying to better understand potential energy. What conclusion is best supported by Lamar’s work?

A) The elastic potential energy is the same for any distance from a reference point.

B) The gravitational potential energy equals the work needed to lift the object.

C) The gravitational potential energy is the same for any distance from a reference point.

D) The elastic potential energy equals the work needed to stretch the object

Answer:

B) The gravitational potential energy equals the work needed to lift the object.

Explanation:

In physics, we know that potential energy is the energy of a body at rest while the energy of a body in motion is known as kinetic energy.

However,the work required to lift a body from it's position of rest is equal to the Gravitational potential energy of that body.

Elastic potential energy is the one that is stored as a result of force applied to deform an elastic object. Thus, it is not equal to the work needed to stretch the object and it is also not the same for any distance from reference point.

Thus, looking at the options, Option B is correct

Explanation:

Answer:

The box displacement after 6 seconds is 66 meters.

Explanation:

Let suppose that velocity given in statement represents the initial velocity of the box and, likewise, the box accelerates at constant rate. Then, the displacement of the object ([tex]\Delta s[/tex]), in meters, can be determined by the following expression:

[tex]\Delta s = v_{o}\cdot t+\frac{1}{2}\cdot a\cdot t^{2}[/tex] (1)

Where:

[tex]v_{o}[/tex] - Initial velocity, in meters per second.

[tex]t[/tex] - Time, in seconds.

[tex]a[/tex] - Acceleration, in meters per square second.

If we know that [tex]v_{o} = 5\,\frac{m}{s}[/tex], [tex]t = 6\,s[/tex] and [tex]a = 2\,\frac{m}{s^{2}}[/tex], then the box displacement after 6 seconds is:

[tex]\Delta s = 66\,m[/tex]

The box displacement after 6 seconds is 66 meters.
