a 1,402-kg car rounds an unbanked curve with a radius of 53 m at a speed of 9.9 m/s. what minimum coefficient of friction must exist between the road and tires to prevent the car from slipping?

Answer: C

Explanation:

Since bulb B is burnt out, the wires can't transfer to bulb A, so that's why bulb A will burn out.

If I get it wrong, sorry. Im still learning.

Answer:

if you need an actual number answer you can use   :Vf = Vi + at.  If you throw the ball it will have an initial force beside gravity accelerating the fall temporarily from greater than throw it downwards, its acceleration (in the absence of air resistance) will be greater than  9.8 m/s2 until it slows back down to a constant 9.8 m/s2 after ( t )amount of time

Explanation:

If you drop a ball, it accelerates downward at 9.8 m/s2. if instead you throw the ball straight downwards While throwing, we apply an additional force other than the gravitational force.

This gives an additional, temporary acceleration along with the gravitational acceleration.

Thus from the instant it is thrown and the instant it leaves your hand, the object is under variable acceleration, the variation of acceleration being the reason of the varying force which we do apply on the object. But once it leaves our hand it is always under constant acceleration of g which is9.8 m/s2

Answer:

The neutral state of an atom is when it's net charge is zero; that is, the number of protons equals the numbers of electrons. Oxygen is the eighth element in the periodic table, with the symbol O. This means that it has eight electrons in its neutral state. Since it is neutral, it also has eight protons!

Answer:

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

The strength of gravity of planets Jupiter and Pluto are 23.1m/s² and  0.6m/s² respectively.

We are given that,

The mass of the shoes =  m=0.500 kg

The weigh  of the shoes on the Jupiter = W₁=11.55 N

The weigh of the shoes on the Pluto = W₂=0.3 N

Therefore, the weight to mass ratio determines the strength of gravity, or the acceleration caused by gravity.

\(g_{j} = \frac{w_{1} }{m}\)

Putting the values in above equation we can get,

\(g_{j} = \frac{11.55N}{0.500kg}\\ g_{j} = 23.1m/s^{2}\)

Since, the gravity strength of planet Jupiter would be 23.1m/s²

\(g_{p} =\frac{w_{2} }{m} \\g_{p} = \frac{0.3N}{0.500kg} \\g_{p} = 0.6 m/s^{2}\)

Thus, the gravity strength of planet Pluto may be 0.6m/s².

The net vertical force on the caboose (C) is

∑ F[v, C] = F[n, C]  - (1.4 kg) g = 0

where F[n, C] is the magnitude of the normal force exerted by the track on the caboose; so we have

F[n, C] = (2.3 kg) g = 13.72 N

which means the coefficient of kinetic friction µ between the caboose and the track is

F[f, C] = 0.46 N = µ (13.72 N)   ⇒   µ = (0.46 N) / (13.72 N) ≈ 0.034

and presumably the coefficient is the same for the locomotive.

The net vertical force on the locomotive (L) is

∑ F[v, L] = F[n, L] - (2.3 kg) g = 0

where F[n, L] is the magnitude of the normal on the locomotive, so that

F[n, L] = (2.3 kg) g = 22.54 N

and so the locomotive is opposed by a frictional force with magnitude

F[f, L] = µ (22.54 N) ≈ 0.76 N

Taking the locomotive and caboose together, the net horizontal force on the system is

∑ F[h] ≈ - F[f, C] - F[f, L] + F[engine] = (2.3 kg + 1.4 kg) (3.1 m/s²)

Solve for F[engine] :

F[engine] ≈ (3.7 kg) (3.1 m/s²) + 0.46 N + 0.76 N ≈ 13 N

An estimate of how much energy per year is needed for 1 gigawatt is approximately 31,536,000,000,000,000 joules (J) per year.

To estimate how much energy per year is needed for 1 gigawatt, we need to consider the unit of measurement for energy, which is joules (J).

A gigawatt is equivalent to 1 billion watts or 1,000,000,000 watts. To calculate the energy per year, we need to multiply this value by the number of seconds in a year.

There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365 days in a year.

So, 1 gigawatt x 1 year = 1,000,000,000 watts x 60 seconds/min x 60 minutes/hour x 24 hours/day x 365 days/year

= 31,536,000,000,000,000 joules (J) per year

Therefore, approximately 31,536,000,000,000,000 joules (J) per year  is an estimate of energy needed for 1 gigawatt.

If the voltage across the capacitor is doubled, then the charge on the capacitor becomes two times that of the initial and energy stored in the capacitor becomes four times (4x) than of the initial.

The formula for calculating the charge on a capacitor is given by:

Qc = CV

where C is the capacitance of the capacitor and V is the voltage across the capacitor.

Since the capacitance of a capacitor is a constant value, the charge on the capacitor is directly proportional to the voltage across it.

Qc∝V

From the above equation, we can see that when the voltage across the capacitor doubles, the charge on the capacitor also doubles from its initial value.

The formula for calculating the energy stored in a capacitor is given by:

Es = ½ CV²

where C is the capacitance and V is the voltage.

Since the capacitance of a capacitor is always constant, the stored energy is proportional to the square of the voltage. Es∝V²

Now that the voltage has been doubled, the formula for stored energy is given by:

new ∝ (2V)²

∝ 4(V)² 

Therefore, energy stored in the capacitor becomes four times than of the initial.

Answer:

When a battery charges a capacitor, the conduction electrons flow from the battery to the plates of the capacitor. As the capacitor becomes charged, the electrons accumulate on the plates, creating a potential difference between the plates. This potential difference causes the flow of electrons to stop once the capacitor is fully charged, and the capacitor can hold a charge.

During the charging process, the voltage across the capacitor increases as more charge accumulates on the plates, while the current decreases as the flow of electrons slows down. When the capacitor is fully charged, the voltage across the capacitor is equal to the voltage of the battery, and the current stops flowing.

In summary, when a battery charges a capacitor, the conduction electrons flow from the battery to the plates of the capacitor, creating a potential difference that charges the capacitor. Once the capacitor is fully charged, the flow of electrons stops.

The conduction electrons in a battery charging a capacitor will flow from the negative terminal of the battery to the positive terminal.

This flow of electrons is known as an electric current. As the electrons move, they transfer energy to the capacitor, which causes the capacitor to become more positively charged. This process of charging continues until the capacitor reaches the same electrical potential as the battery.

Once the capacitor is fully charged, the electrons will no longer flow and the capacitor will remain at the same voltage as the battery.

The conduction electrons have transferred energy from the battery to the capacitor, allowing the capacitor to store electrical energy.

If the magnetite is aligned with the south pole, it indicates that the magnetite possesses a north pole. Magnetite is a naturally occurring mineral that exhibits strong magnetic properties. Like any magnet, it has two magnetic poles, the north pole and the south pole.

In a magnet, opposite poles attract each other, while like poles repel each other. The north pole of a magnet is attracted to the south pole of another magnet, while the north poles repel each other, as do the south poles.

Therefore, if the magnetite is aligned with the south pole, it means that the opposite, or north pole, is pointing in the opposite direction. The alignment of the magnetite with the south pole suggests that the north pole of a magnet would be attracted to it. This corresponds to the concept of magnetic polarity, where the north and south poles of magnets exhibit opposite polarities and attract each other.

Understanding the polarity of magnets is essential in various applications, such as magnetic compasses, electric motors, and magnetic storage devices. The proper alignment and recognition of the north and south poles are crucial for utilizing the attractive and repulsive properties of magnets in different technological and scientific contexts.

BASE jumping is the recreational sport of jumping from fixed objects, using a parachute to descend safely to the ground. "BASE" is an acronym that stands for four categories of fixed objects from which one can jump: building, antenna, span, and earth (cliff).[1][2] Participants exit from a fixed object such as a cliff, and after an optional freefall delay, deploy a parachute to slow their descent and land. A popular form of BASE jumping is wingsuit BASE jumping.

Explanation:

In contrast to other forms of parachuting, such as skydiving from airplanes, BASE jumps are performed from fixed objects which are generally much lower altitude, and BASE jumpers typically carry only one parachute. BASE jumping is significantly more hazardous than other forms of parachuting, and is widely considered to be one of the most dangerous extreme sports

Answer:not sure

Explanation:

Sorry:(

Answer:

1.) Displacement = 32.08m

2.) Velocity = 55km/h

3.) Acceleration = 94.29 km/h^2

Explanation:

Given that the train takes 35 minutes to cover the distance between the two towns. The train's average speed is 55 kilometers per hour. That is,

Time t = 35 minute

Convert it to hours by dividing it by 60

35/60 = 7/12 hours

Speed = 55 km/h

The displacement of the car is:

Displacement = 55 × 7/12 = 32.08 m

The velocity of the car will be 55 km/h

The acceleration of the car will be:

Acceleration = velocity/time

Substitute velocity and time into the formula

Acceleration = 55 ÷ 7/12

Acceleration = 94.29 km/h^2

In the given figure, if I = 2A and I2 = 6A, the relation between F1 and F2 is, F1 = F2.

The two forces are an action reaction forces. They act on different wires, and have equal magnitudes but opposite directions. So, they are equal.

We find the discussion of action and reaction forces in newton's third law.

According to the Newton's third law states that If there is an action force, there must be a reaction force. If there is an object A which exerts a force on object B, then object B must also exerts an equal and opposite force on object A. In other words, we can say that forces result from interactions.

Action and reaction forces acts on different objects. they exist in pair. They are always equal in magnitude and opposite in direction.

False. Thousands of years ago, astronomers did recognize that the Earth is spherical; however, the specific observation of the Earth's shadow during lunar eclipses being circular was not the primary evidence for determining the Earth's shape. Instead, several other observations and deductions were made to support the idea of a spherical Earth.

One of the earliest and most famous pieces of evidence for a spherical Earth was the observation of ships disappearing hull-first as they sailed away from shore. Additionally, the changing positions of stars and constellations as one traveled further north or south, the shape of the Earth's shadow on the Moon during partial lunar eclipses, and the curved shape of the horizon were all contributing factors that led ancient astronomers to conclude that the Earth is spherical.

While the circular shape of the Earth's shadow during lunar eclipses does provide support for a spherical Earth, it was not the sole basis for this understanding.

Explanation:

To power the device using a solar panel, we need to use a battery to store the energy during peak sunlight hours. The battery can then be used to power the device during times when there is no sunlight. The device requires a power of more than 22.5W, it cannot be powered directly by the solar panel.

To calculate if we can power a device with a resistance of 10Ω using direct power from a solar panel, we need to consider the panel's power output and the device's power requirement. At sunrise/sunset, the solar panel's power output is significantly lower than during peak sunlight hours. Therefore, it is unlikely that the panel could provide enough power to operate the device.

Assuming the solar panel can produce a maximum of 100W at peak sunlight hours, we can calculate the current that the panel can provide using Ohm's Law.

Current (I) = Voltage (V) / Resistance (R)
I = 15V / 10Ω
I = 1.5A

Power (P) = Current (I) x Voltage (V)
P = 1.5A x 15V
P = 22.5W

Since the device requires a power of more than 22.5W, it cannot be powered directly by the solar panel.

Therefore, to power the device using a solar panel, we need to use a battery to store the energy during peak sunlight hours. The battery can then be used to power the device during times when there is no sunlight.
