Q7) A box sliding with a velocity of 5 m/s accelerates at 2 m/s^2. How
much is the box displacement after 6 s?
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.
What is the SI unit of measurement for speed? A.meters per second (m/s) B.meters per second (m/s) C.Miles per hour (mi/hr) D.Miles per hour (mi/hr) Kilometers per minute (km/min) Kilometers per minute (km/min) Grams per unit (g/u) Grams per unit (g/u)
Explanation:
The SI unit of measurement for speed is metres per second (m/s) .
Speed : The distance travelled by a body per unit time is know as speed.

Lamar writes several equations trying to better understand potential energy. What conclusion is best supported by lamar's worm?
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
state kepler's three laws of planetary motion
Answer:
1) every planet’s orbit is an ellipse with the Sun at a focus.
2) a line joining the Sun and a planet sweeps out equal areas in equal times.
3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its orbit.
Un automóvil viaja a la velocidad de 10 m/s. Se acelera Durante 12s y aumenta su velocidad hasta 70 m/s ¿Que aceleración experimenta el automóvil?
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
TRUE OR FALSE, PLEASEE HELPPP ASAP
6) The amount of work done on an object depends on the final speed of the object
7) 1 Horsepower (hp) is equal to 746 Watts.
8) The SI unit for Work is the Joule.
9) The lower the percentage, the better the efficiency
10) The Work-Energy theorem states that the change in kinetic energy also equals the amount of work done on an object or system.

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

How is atomic energy is produced ?
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.

1) A mass of 20kg was lifted from a height of 5m to 12m. How much work was done?
Answer:
1400joules
Explanation:
work(j)= force × distance.
Distance is from 5m to 12 that is 7m
Force, we weren't given, and the formula is mass × acceleration due to gravity. mass is 20kg and a is 10 or 9.8
f= 20×10
f=200
work= 200 × 7
work= 1400joules
