If the absolute temperature of an object is tripled, the thermal power radiated per unit surface area of this object will increase by a factor of 27.

This is because the thermal power radiated per unit surface area of an object is proportional to the fourth power of its absolute temperature, according to the Stefan-Boltzmann law. The equation for this law is:

P = εσT^4

Where P is the thermal power radiated per unit surface area, ε is the emissivity of the object, σ is the Stefan-Boltzmann constant, and T is the absolute temperature of the object.

If the absolute temperature is tripled, the equation becomes:

P = εσ(3T)^4

P = εσ(81T^4)

P = 81εσT^4

Therefore, the thermal power radiated per unit surface area will increase by a factor of 81/3 = 27.

The magnitude and direction of the magnetic force on a particle of charge is - 2.21 in the opposite direction.

Magnetic force is defined as the electrically charged particles that are in motion and exhibit either attraction or repulsion. The interaction between moving and stationary charged particles is explained by the electromagnetic force, commonly known as the Lorentz force.

The magnitude and direction of the magnetic force can be calculated as

F = q v B sinθ

Given q = 13 C

v = - 20 m/s

B =  0.5 T²

F = 13 C x - 20 m/s x 0.5 T² sinθ

F = - 130 sinθ

Let θ is equal to 1

Then, F = 130 sin1

F = - 130 x 0.017

F = - 2.21

Thus, the magnitude and direction of the magnetic force on a particle of charge is - 2.21 in the opposite direction.

For someone with a negative Weber slope for weight detection, it would be easier to tell the difference between 20 pounds and 21 pounds.

The Weber's Law states that the just noticeable difference (JND) between two stimuli is proportional to the magnitude of the stimuli. A negative Weber slope indicates that the JND decreases as the magnitude of the stimuli increases. In this case, as the weight increases, the person's ability to discriminate between the weights becomes easier.

When a long wire carries a current towards the east in a magnetic field that is directed due south, the direction of the magnetic force on the wire is vertically downward.

The force exerted by a magnetic field on a moving charged particle is described by the Lorentz force equation. The direction of the magnetic force F on a moving charged particle with charge q is given by F = qv x B, where v is the velocity of the particle and B is the magnetic field vector.

The direction of the magnetic force is perpendicular to both the velocity of the particle and the direction of the magnetic field.

If the current in the wire is towards the east and the magnetic field is directed towards the south, then the magnetic force on the wire will be perpendicular to both these directions, which is vertically downward.

Therefore, the correct option is e) vertically downward.

Explanation:

Jessie will run for a duration of time, which is the time it takes for Melissa and Rory to meet each other.

Together combined, Melissa and Rory runs at 14km/h. The bike trail is 21km, so it will take 1.5 hours.

Jessie runs at 18km/h, so Jessie will run 18 * 1.5 = 27km.

The price of E85 (85% ethanol, 15% gasoline) would need to be $2.42 per gallon for its cost to be the same as that of pure gasoline.

To determine the price of E85 that would make its cost equivalent to that of pure gasoline, we need to consider the energy density and the proportion of ethanol and gasoline in E85.

Given that pure gasoline has an energy density of 115,600 BTU per gallon and ethanol has an energy density of 75,670 BTU per gallon, we can calculate the energy content of E85.

Since E85 is composed of 85% ethanol and 15% gasoline, we can calculate the energy density of E85 as follows:

Energy density of E85 = (0.85 * energy density of ethanol) + (0.15 * energy density of gasoline)

                   = (0.85 * 75,670 BTU/gal) + (0.15 * 115,600 BTU/gal)

Now, to determine the price of E85, we compare the energy content of E85 to that of pure gasoline:

Price of E85 / Price of pure gasoline = Energy content of E85 / Energy content of pure gasoline

Given that the price of pure gasoline is $3.70 per gallon, we can rearrange the equation to solve for the price of E85:

Price of E85 = (Energy content of E85 / Energy content of pure gasoline) * Price of pure gasoline

Substituting the values, we can calculate that the price of E85 would need to be $2.42 per gallon for its cost to be equivalent to that of pure gasoline.

Explanation:

The false statement is B) Homolytic bond cleavage yields neutral radicals in which each atom gains one electron.

In homolytic bond cleavage, each atom retains one electron from the shared pair of electrons, resulting in the formation of two neutral radicals, where each atom retains its original number of electrons.

No atoms gain or lose electrons in this process.

In a homolytic bond cleavage, a covalent bond is broken, and the shared pair of electrons is split equally between the two atoms involved in the bond.

This results in the formation of two neutral radicals, with each atom retaining one of the electrons from the shared pair.

A radical is a chemical species characterized by the presence of an electron that is unpaired, meaning it does not have a partner electron with which it forms a complete pair. When a covalent bond is homolytically cleaved, each atom involved in the bond gains one electron, resulting in the formation of two radicals.

These radicals are highly reactive due to the presence of the unpaired electron, which makes them prone to participate in further chemical reactions.

It's important to note that in homolytic bond cleavage, there is no transfer of electrons from one atom to another.

Instead, the bond is broken in a way that allows each atom to retain one of the electrons, leading to the formation of two neutral radicals.

Therefore, statement B, which suggests that each atom gains one electron, is false.

The similarity between the last time the globe warmed and the climate change occurring today is that both are caused by the emission of greenhouse gases into the atmosphere.

Greenhouse gases trap heat from the sun in the atmosphere, causing the earth's temperature to increase. The difference between the two is that the current warming is happening much faster than the last time the globe warmed. This is largely due to the amount of greenhouse gases that have been released into the atmosphere since the industrial revolution. In addition, the current warming is affecting the global climate in more extreme ways than the last time the globe warmed, with more frequent and intense storms, droughts, and heatwaves.

The motion in which a body has constant horizontal component of velocity

but changing vertical component of velocity is called projectile motion. Every projectile body has PROJECTILE MOTION.

The Vertical Velocity will decrease during upward motion and increase during downward motion, by the factor,

\(V_f = V_iSin(theta) - gt (Upward Motion)\\\\V_f = V_iSin(theta) + gt (Downward Motion)\)

Where,

Vf = final velocity

Vi = initial velocity  

Theta θ is the angle at which projectile is fired

g is acceleration due to gravity

t is time  

B) HORIZONTAL VELOCITY:

HORIZONTAL VELOCITY remains constant. According to Newton's 1st Law object in motion stays in motion until a force acts on it. There are no forces acting on a projectile in the horizontal direction (neglecting air resistance), therefore the velocity is constant.

Angle = θ(theta) = 30

Initial Velocity = \(V_0 = 150 ms^{-1}\)

g = 10 m/s^2

Time taken to reach maximum height = T = ?

The time taken by the projectile to reach the maximum height is given by,

                                      \(T = \frac{V_0Sin(theta)}{g}\\\\T = \frac{150Sin(30)}{10}\\\\T = \frac{150x0.5}{10}\\\\T = \frac{75}{10}\\\\T = 7.5 seconds\)

Explanation:

We see that induced emf when the top of the magnet passes out of the loop would be greater than the induced emf when the bottom of the magnet enters into the loop.

As the magnet moves down the magnetic flux through the coil increases. According to Lenz's Law, a coil induces a current that opposes the magnetic flux. The direction of the induced emf is determined by the right-hand rule. According to the rule, if the thumb points in the direction of movement of the conductor and the index finger points in the direction of the magnetic field, then the index finger represents the direction of the induced current.

When the north end of the magnet moves into the coil EMF is induced in the coil and current begins to flow. The direction of flow will be against the movement of the magnet. Therefore, the direction of the generated current is counterclockwise when viewed from the magnet side. The magnitude of the magnetic field can change over time. The area enclosed by the loop can change over time. The angle between the magnetic field and the loop normal can change over time.
