Most asteroids _____.

A) revolve around Jupiter in the asteroid belt
B) take millions of years to orbit the sun
C) are found between Mars and Jupiter
D) are larger than 1,000 km in diameter

Answer:answer is B

Explanation:

Answer:

F = 12000 N = 12 KN

Explanation:

First we need to find the acceleration of the bad boys by using second equation of motion:

s = Vi t + (1/2)at²

where,

s = distance covered = 5 m

Vi = Initial Velocity = 0 m/s

t = time taken = 0.5 s

a = acceleration = ?

Therefore,

5 m = (0 m/s)(0.5 s) + (1/2)a(0.5 s)²

a = 2(5 m)/(0.5 s)²

a = 40 m/s²

Now, we calculate the force applied by Newton's Second Law:

F = ma

where,

F = force = ?

m = mass of bad guys = 300 kg

Therefore,

F = (300 kg)(40 m/s²)

F = 12000 N = 12 KN

Answer: The correct option is C ( Chemical energy > Electrical energy > Sound energy)

Explanation:

Energy is defined as the capability or ability to perform work. It is measured in joules. It is a scalar quantity ( that is, fully described by its magnitude).

The principle of conservation of energy states that in a closed system, energy can neither be created nor destroyed during transformation. Although energy can be transformed so that the total energy of a given system always remains constant. The different forms of energy includes:

--> mechanical energy

--> Chemical energy

--> Heat energy

--> sound energy

--> electrical energy

--> sound energy

To be able to create a circuit that will produce siren sounds, a source of power supply will be needed. This would be derived from a battery cell( Chemical energy). This supplies current (electrical energy)to the sound system of the circuit to produce the siren sounds heard(sound energy). Therefore the energy transformation is from CHEMICAL ENERGY to ELECTRICAL ENERGY to SOUND ENERGY.

Answer:

Acceleration, [tex]a=23\ m/s^2[/tex]

Explanation:

Given that,

The statue of Liberty is at a height of 46 m.

Jean Grey needs to fly from  rest on the ground to the top of the Statue of Liberty (46 m) in 2.0  seconds.

We need to find her minimum average acceleration during her  ascent. Let it is t. Using the second equation of motion to find it.

[tex]h=ut+\dfrac{1}{2}at^2\\\\h=\dfrac{1}{2}at^2\\\\a=\dfrac{2h}{t^2}\\\\a=\dfrac{2\times 46}{(2)^2}\\\\a=23\ m/s^2[/tex]

So, the constant acceleration is [tex]23\ m/s^2[/tex] for the entire distance.

hello your question is incomplete attached below is the complete question

answer : [tex]F_{E} > F_{F} > F_{A} = F_{B} > F_{C} =F_{D}[/tex]

Explanation:

The explanation behind the reasoning is attached below

Ranking the magnitude of the net electric force on the lower-left particle from the greatest to the least

[tex]F_{E} > F_{F} > F_{A} = F_{B} > F_{C} =F_{D}[/tex]

The magnitude of the net electric force on the lower-left particle. greatest to least in order of [tex]\rm F_E > F_F > F_A= F_B > F_C=F_D[/tex]

The electric force between the two charges is directly propotional to the product of the charge and inversly propotional to the square of the distance between them.

The electric force for each case found as;

[tex]\rm F_1 = \frac{2K q^2}{q^2} \\\\ \rm F_2 = \frac{2K q^2}{q^2} \\\\[/tex]

[tex]\rm F_3= 2 m \\\\ \rm \rm F_4= 4\sqrt{3} m\\\\ \rm F_5= 4m[/tex]

Hence the magnitude of the net electric force on the lower-left particle. greatest to least in order of [tex]\rm F_E > F_F > F_A= F_B > F_C=F_D[/tex]

Explanation:

Answer:

58.24 Km/h.

Explanation:

From the question given above, the following data were obtained:

Distance (d) = 495 Km

Time (t) = 8 h 30 mins

Speed (S) =?

Next, we shall express 8 hours 30 mins to hours.

We'll begin by convert 30 mins to hour.

60 mins = 1 h

Therefore,

30 mins = 30 mins × 1 h/ 60 mins

30 mins = 0.5 hour.

Thus,

8 h 30 min = 8 + 0.5 = 8.5 hours

Speed is define as the distance travelled per unit time. Mathematically, it is expressed as:

Speed = Distance /time

With the above formula, we can obtain the speed as shown below:

Distance (d) = 495 Km

Time (t) = 8.5 hour

Speed (S) =?

Speed = Distance /time

Speed = 495 Km / 8.5 hour

Speed = 58.24 Km/h

Thus, the speed is 58.24 Km/h.

0.6 m

Explicación:

0,15 m

Explicación:

Paso uno:

dado

Fuerza F = 250N

diámetro d1- 16 cm am = 0.16 m

A1 = πd1 ^ 2/4 = 3.142 * 0.16 ^ 2/4

= 0.02 m ^ 2

Carga L = 3500N

A2 =?

Segundo paso:

sabemos que la presión aplicada a un extremo para levantar una carga en el otro extremo se expresa matemáticamente como

F1 / A1 = F2 / A

sustituir

250 / 0.2 = 3500 / A

cruzar multiplicar

A2 = 0.02 * 3500/250

A2 = 70.3 / 250

A2 = 0.28

sabemos que área = πd ^ 2/4

0.28 = πd2 ^ 2/4

0.28 = 3.142 * d2 ^ 2/4

0.28 * 4 / 3.142 = d2 ^ 2

0.36 = d ^ 2

d = √0.36

d = 0.6 m
