HELP!!!

i’ve been stuck at this question for a whole day

Answer:

8000 kg/cm^3

Explanation:

The density formula is P = M/V

Density = P = ? expressed in kg/m^3

M = mass = 40,000 kg

V = volume = 5 m^3

P = 40,000/5

P = 8000 kg/m^3

Answer:

a) La carga eléctrica máxima que puede acumular la pila recargable es 6480 coulombs.

b) La máxima cantidad de energía acumulada por la pila recargable es 7776 kilojoules.

c) No son exactas todas las cifras significativas que aparecen en el dato de la etiqueta.

Explanation:

a) La capacidad de la batería es la corriente constante suministrada por la batería durante su tiempo de servicio. En este caso, puesto que la batería tiene una capacidad de [tex]1800\,mAh[/tex], significa que la batería entrega una corriente de 1.8 amperios durante una hora. La máxima cantidad de carga es estimada por la siguiente expresión:

[tex]q = C\cdot \Delta t[/tex] (1)

Donde:

[tex]C[/tex] - Capacidad de la pila recargable, medida en amperios-hora.

[tex]\Delta t[/tex] - Tiempo de servicio, medido en horas.

[tex]q[/tex] - Carga eléctrica, medida en coulombs.

Si tenemos que [tex]C = 1.8\,A[/tex] y [tex]\Delta t = 3600\,s[/tex], entonces la máxima cantidad de energía que puede acumular es:

[tex]q = (1.8\,A)\cdot (3600\,s)[/tex]

[tex]q = 6480\,C[/tex]

La carga eléctrica máxima que puede acumular la pila recargable es 6480 coulombs.

b) La máxima cantidad de energía suministrada por la batería ([tex]E_{max}[/tex]), medida en joules, es definida por la siguiente expresión:

[tex]E_{max} = q\cdot V[/tex] (1)

[tex]E_{max} = (6480\,C)\cdot (1.2\,V)[/tex]

[tex]E_{max} = 7776\,J[/tex]

La máxima cantidad de energía acumulada por la pila recargable es 7776 kilojoules.

c) Sabemos que las unidades estándar del voltaje y la capacidad son el volt y el amperio-hora, respectivamente. Entonces, si asumimos que las cifras significativas quedan representadas por el número de decimales y que se considera razonable que haya una cifra significativa, entonces tenemos que cada variable es en formato de ingeniería:

[tex]C = 1.8 Ah[/tex] y [tex]V = 1.2\,V[/tex].

Al mutiplicarse cualquiera de estas cantidades por un número con una cifra significativa deja con un producto con dos cifras significativas. Por tanto, se pierde precisión al realizarse operaciones de multiplicación.

No son exactas todas las cifras significativas que aparecen en el dato de la etiqueta.

Heya!!

For calculate force, lets applicate second law of Newton:

                                                    [tex]\boxed{F=ma}[/tex]

                                                 Δ   Being   Δ

                                                 F = Force = ?

                                            m = Mass = 50 kg

                                        a = Aceleration = 7,2 m/s²

⇒ Let's replace according the formula:

[tex]\boxed{F= 50\ kg * 7,2 m/s^{2}}[/tex]

⇒ Resolving

[tex]\boxed{ F = 360\ N}[/tex]

Result:

The force is 360 Netwons.

Good Luck!!

Answer:

a) 0 m/s

b) 4 m/s

Explanation:

The average velocity would end up being 0 because it is displacement over time and the displacement here is 0. However, speed is total distance over time which here is 400/100 so it is 4.

Explanation:

I cant explain it but when i asked my teacher thats what he told me

Answer: A) Clare  B) Clare  c) 108 miles

Explanation:

Step 1

For Laura

Time taken by Laura = 3hours

Speed = 44mphn

Distance covered = speed x time

=  44 X 3= 132 miles

For Clare

Distance covered =144 miles

time = 4 Hours

Speed = Distance / Time

144/ 4 =36 mph

Step 2

a) Who travels the greater distance= Clare travels at a greater distance of 144 miles.

b)Whose speed is the slower= Clare speed is slower with 36mph

c)How far would Laura travel if she drove for 3 hours at the same speed

as Clare?

if Laura's speed = Clare speed = 36mph

time = 3hours

Distance= Speed x time

= 36 mph x 3 hours

108miles

Answer:

U = 66,150 J

Explanation:

Gravitational Potential Energy

Gravitational potential energy is the energy stored in an object because of its vertical position or height in a gravitational field.

It can be calculated with the equation:

U=m.g.h

Where m is the mass of the object, h is the height with respect to a fixed reference, and g is the acceleration of gravity or [tex]9.8\ m/s^2[/tex].

The child of mass m=45 Kg is perched above a h=150 m ravine. His gravitational potential energy is:

[tex]U=45~Kg\cdot 9.8\ m/s^2\cdot 150\ m[/tex]

U = 66,150 J

Answer:

555

Explanation:

Explanation:

... in every interaction, there is a pair of forces acting on the two interacting objects. The size of the force on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.

Answer:

Digestion begins in the mouth, when you chew.

Answer:

88km E

Explanation:

25 km is added already

then if we take the formula of speed(V)

V=d/t

and rearrange it to subject d (distance)

d= V x t

we get

d= 42km/h x 1.5hrs

we get

63 km

now if we add the already travelled 25 km to this additional distance

63km + 25km = 88km

Thus the final distance traversed by the ship from its origin is

88km E

The amount of sun’s energy that hits an area helps determine the climate of that area. The Brazilian Rainforest has a tropical climate that averages of up to 300 mm of rain during some months. Which of the following best describes the role of the water cycle in determining the rainforest’s weather?

Answer:

b

Explanation:

The relative distance can calculate by dividing the time travelled by the speed difference between points A and B. Considering that B is going more quickly than A, we substract A's speed from B's speed.

Relative Speed = Speed of B - Speed of A

Relative Speed = 6 km/h - 5 km/h

Relative Speed = 1 km/h

Now, we can calculate the relative distance traveled by B after 2 hours:

Relative Distance = Relative Speed * Time

Relative Distance = 1 km/h * 2 hours

Relative Distance = 2 km

Therefore, B will be 2 kilometers away from A after 2 hours of walking in the same direction.
