Explanation: Try calculating 8.932 times

10^22 kg

Answer:

F = 2.68 x 10²³ N

Explanation:

The force between lo and Jupiter is given by Newton's Gravitational Formula:

[tex]F = \frac{Gm_1m_2}{r^2} \\[/tex]

where,

F = Force = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²

m₁ = mass of lo = 8.932 x 10²² kg

m₂ = mass of Jupiter = 1.9 x 10²⁷ kg

r = distance between lo and Jupiter = 4.22 x 10⁸ m

Therefore,

[tex]F = \frac{(6.67\ x\ 10^{-11}Nm^2/kg^2)(8.932\ x\ 10^{22}\ kg)(1.9\ x\ 10^{27}\ kg)}{(4.22\ x\ 10^8\ m)^2}[/tex]

F = 2.68 x 10²³ N

Answer:

t = 125 seconds

Explanation:

Given that,

The mass of a train, m = 50,000 kg

Initial speed, u = 5 m/s

Stopping force, F = 2000 N

We know that,

Force, F = ma

Where

a is acceleration

[tex]F=\dfrac{m(v-u)}{t}\\\\t=\dfrac{m(v-u)}{F}\\\\t=\dfrac{50000(0-5)}{-2000}\\\\t=125\ s[/tex]

So, it will take 125 seconds to stop the car.

Answer:

You add up all the individual resistances of the resistors in the series circuit to get the total resistance of the circuit

Explanation:

A series circuit is a circuit that has most of its components connected end-to-end

following what was stated above, in a series circuit, the resistors are connected end to end. This means that the current that flows out from one of the resistors flows into the next one. As a result of this, the current through all the resistors is the same.

To get the total equivalent resistance in a series circuit, you add up all the individual resistances of the resistors in the series circuit. This should give you the total resistance in the circuit.

i.e

Total resistance = R1 + R2 + R3 ....

Answer:

a)   v = 0,  a = - 15 pi²

b) v = - 40.8 cm / s,  a = -74.2 cm / s

Explanation:

the simple harmonic motion is described by the expression

        x = A cos (wt + Ф)

in that case they indicate the amplitude of the movement

        A = 15 cm

angular velocity and period are related

        w = 2π / T

         w = 2π/ 2

         w = π rad / s

speed is defined by

         v = dx / dt

          v = -A w sin (wt + Ф)

acceleration is defined by

         a = dv / dt

         a = - A w² cos (wt + Ф)

In order to evaluate this expression we must know the value of the phase constant (Ф) that meets the initial conditions, the most common thing is that the system is released, v = 0 for y = 0 s, let's use the speed equation

          v = -A w sin (0+ Ф)

for this expression to be zero, the sine must be zero, so

         Ф= 0

now let's write the equations for our case

         v = - 15 π sin (π t)

         a = - 15 π² cos (π t)

a) for x = 0

          v = 0

          a = - 15 pi²

b) for x = 7.5 cm

Let's find out how long it takes to get to this position

          x = 15 cos (π t)

          7.5 / 15 = cos π t

          pi t = cos⁻¹ 0.5

          t =  1.047/π

don't forget that the angles are in radians

          t = 0.333 s

now let's look for speed and acceleration

         v = - 15 π sin (π 0.333)

         v = - 40.8 cm / s

         a = - 15 π² cos (π 0.333)

         a = -74.2 cm / s

Answer:

Option C, The 30 m telescope can observe objects 9 times fainter, and with 3 times smaller angular size, than the 10 m telescope.

Explanation:

As we know,

The surface brightness of the object viewed through telescope is proportional to the square of the diameter of the lens

Thus, Brightness ([tex]B_{30}[/tex]) of 30 m telescope would be proportional to [tex]30^2[/tex]

Brightness of 10 m ([tex]B_{10}[/tex]} telescope would be proportional to [tex]10^2[/tex]

Thus, the ration of the two would be

[tex]\frac{B_{30}}{B_{10}} = \frac{30^2}{10^2} \\\frac{B_{30}}{B_{10}} = \frac{9}{1} \\B_{30} = 9 * B_{10}[/tex]

Thus, brightness of 30 m telescope would be able to view 9 times fainter object as compared to the 10 m telescope.

Also , 30 m telescope would be able to view 3 times smaller angular sized object as compared to the 10 m telescope

Hence, option C is correct

Answer:

13 N

Explanation:

From the question,

(F₁+F₂)-F' = ma................ Equation 1

Where F₁= Jack's force, F₂ = Jill's force, F' = Friction force, m = mass of the object, a = acceleration of the object.

Given: F₂ = 4 N, F' = 2 N, m = 3 kg, a = 5 m/s²

Substitute these values into equation 1 and solve for F₁

(F₁+4)-2 = 3×5

(F₁+4)-2 = 15

F₁+4 = 15+2

F₁+4 = 17

F₁ = 17-4

F₁ = 13 N

Hence the force applied by Jack is 13 N

Answer:

a)It is NOT possible using this telescope, to see the two stars as separate stars

b)[tex]d_{min} =28.466m[/tex]

Explanation:

From the question we are told that:  

Diameter of lens,[tex]d = 25 cm \approx 0.25 m[/tex]

Distance from both star [tex]D_f= 2*10^{17} m[/tex]

Distance between both stars [tex]D_b= 6*10^9 m[/tex]

Wavelength of light [tex]\lambda =700 nm \approx 700*10^-9 m[/tex]

Generally the equation for angle subtended by the two stars at the lens  is mathematically given by

 [tex]\theta=\frac{D_f}{D_b}[/tex]

 [tex]\theta=\frac{6*10^9}{2*10^{17}}[/tex]

 [tex]\theta=3.0*10^{-8} rad[/tex]

Generally the equation for minimum angular separation of two object is mathematically given by

[tex]\theta_{min} = 1.22*\lambda/d[/tex]  

[tex]\theta_{min}= \frac{1.22*700*10^-9}{0.25}[/tex]  

[tex]\theta_{min}= 3.416*10^-^6 rad[/tex]

Therefore

 [tex]\theta < \theta_{min}[/tex]

[tex]3.0*10^{-8} rad< 3.416*10^-^6 rad[/tex]

It is NOT possible using this telescope, to see the two stars as separate stars

b)

Generally the equation for minimum diameter of the lens is mathematically given by

  [tex]d_{min} =\frac{ 1.22*\lambda}{\theta}[/tex]

  [tex]d_{min} =\frac{ 1.22*700*10^{-9}}{3*10^{-8}}[/tex]

  [tex]d_{min} =28.466m[/tex]

Answer:

skateboard mid-ollie is being actively steered. This is exactly what makes doing an ollie so hard. It's not enough to get the skateboard up into the air - you also have to steer it while it's in the air. You should keep your hands up in the hair a bit to help with balance, scrunch your legs a bit down to have a proper and effective jump. wear nee pads incase you dont fix the landing. Practice jumping on ur skate board tho, if u jump at it without knowing much youll just get hurt.

Explanation:

Answer: When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel. Furthermore, when a liquid is poured from one vessel to another, it retains its volume (as long as there is no vaporization or change in temperature) but not its shape.

Explanation: A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.

In a symbiotic relationship, both organisms involved benefit or are neutrally affected. Symbiosis is a close and long-term interaction between two different species.

The term "symbiosis" encompasses mutualism, commensalism, and parasitism. In mutualism, both organisms benefit from the interaction, such as in the case of bees and flowers where bees obtain nectar and pollen while also helping flowers to pollinate.

In commensalism, one organism benefits while the other is neither helped nor harmed, such as remora fish that attach to sharks for transportation and feeding on scraps left by the shark. In parasitism, one organism benefits while the other is harmed, such as ticks that feed on blood from a host animal.

Answer:

I'm not sure how to use it using the Series, but it would be the plastic comb

Explanation:

In the winter, it's likely to be cold and the glass would absorb that energy, also making it cold. in order to be able to hold it, you would need something warm, thus making the plastic one the better option as it is less likely to absorb the cold energy

Answer:

what are you asking exactly?

Answer:

Explanation:

Because the total energy available to the ball doesn't change whatsoever during its entire trip from the window to the ground,

TE = KE + PE which says that the total energy available to a system is equal to the kinetic energy of the system plus the potential energy, and that this value will not ever change (because energy cannot be created or destroyed. Sound familiar?) If the ball is being held still before it is dropped from some height off the ground, it is here that the total energy can be determined, and that total energy at this point is all potential, since the ball is not moving while someone is holding it and getting ready to drop it. The SECOND it starts to fall, the potential energy begins to be converted to kinetic. As the potential energy is losing value, the kinetic is gaining it at the same rate (again, energy doesn't just disappear; it has to go somewhere. Here, it goes from potential to kinetic a little at a time). When the ball finally hits the ground, or an INSTANT BEFORE it hits the ground, the potential energy is 0 because the height of something on the ground has a height of 0. At this instant, right before the ball hits the ground, is where the KE is the greatest. All the energy at that point has been converted from potential to kinetic.

Long story short, choice B is the one you want.
