Why is Coulomb's proportionality constant so much larger than Newton's?

The term you are looking for is "chemical battery". Chemical batteries work by converting chemical energy into electrical energy through a series of chemical reactions. These reactions take place within the battery's cells, which are composed of two electrodes and an electrolyte.

When the battery is connected to a circuit, the chemical reactions produce an electrical current that can be used to power devices. Chemical batteries are widely used in many applications, including consumer electronics, electric vehicles, and renewable energy systems. They are a crucial component of our modern technological society, and ongoing research is focused on developing more efficient and sustainable battery technologies to meet growing energy demands.

The value of the constant relating energy and frequency is Planck's constant, denoted by the symbol h and has a value of 6.626 x 10^-34 J s.

The relationship between energy and frequency is represented by the equation E = hf, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the photon. This equation shows that energy and frequency are directly proportional to each other. In other words, as the frequency of a photon increases, its energy increases as well. Likewise, as the frequency of a photon decreases, its energy decreases.

Planck's constant is a physical constant that relates the energy of a photon to its frequency. It is denoted by the symbol h and has a value of 6.626 x 10^-34 J s.

The average power developed by the boy during the climb is approximately 29.4 W.

In physics, the amount of energy transferred or converted per unit time is called power.

total height = number of steps x height of each step

total height = 30 x 0.15 m = 4.5 m

Given, time = 60 s

As power = work done / time

work done = force x distance

force = mass x gravity

mass is boy's mass (40 kg) and gravity is acceleration due to gravity (9.81 m/s²).

force = 40 kg x 9.81 m/s² = 392.4 N

The distance that the boy moves is equal to the total height that he has climbed: distance = total height = 4.5 m

work done = force x distance

work done = 392.4 N x 4.5 m = 1765.8 J

power = work done / time

power = 1765.8 J / 60 s

power ≈ 29.4 W

Therefore, the average power developed by the boy during the climb is approximately 29.4 W.

As for the anomalous behavior of water, water has a higher boiling point and melting point as compared to other substances with similar molecular weight. This is due to the strong hydrogen bonding between water molecules, which requires more energy to break the bonds and change the state of water from solid to liquid to gas.

The force in the cable when the rod is in the position shown is 735.78 N. To determine the force in the cable, we need to find the tension force acting in the cable. We can start by considering the equilibrium of forces acting on the rod.
Since the collar at A is smooth, there will be no frictional force acting on it, the only forces acting on the rod are its weight (W) and the tension force (T) in the cable.

We can resolve these forces in the vertical direction, since the rod is in a horizontal position.
By applying the principle of equilibrium, we have:

Σ Fy = 0
T - W = 0
T = W

Substituting the value of weight (W) of the rod, we have:

T = mg = 75 kg x 9.81 m/s² = 735.78 N

Therefore, the force in the cable when the rod is in the position shown is 735.78 N. To determine the force in the cable when the rod is in the position shown, we will follow these steps:

50 meters north in 10 seconds.

speed = distance ÷ time = 50 meters ÷ 10 seconds = 5m/s

Answer:

At positions C and E potential energy is maximum. At position D kinetic energy is maximum.

Explanation:

Answer:

Explanation:

They traveled this distance in 2 parts, essentially. Part 1 had an average speed for a certain number of hours, part 2 had an average speed for a certain number of hours, and those 2 parts taken together took them a distance of 364 km. In equation form, that looks like this:

km/hr part 1 + km/hr part 2 = 364 km

Now we need to find each part on the left side of that equation. Part 1 first:

We traveled 65 km/hr for 2 hours, so that took us

\(65\frac{km}{hr}*2hr\) and canceling out the hour label, we have that in part 1 we got

65(2) = 130 km. Good. Now onto the second part, where our unknown is.

We traveled 78 km/hr the second part for x hours, so that took us

\(78\frac{km}{hr}*xhr\) and canceling out the hour label, we have that in part 2 we got

78x km. Now we can fill in the main equation (the one in bold print)

130 km + 78x km = 364 km and subtracting 130 km from both sides:

78x km = 234 km and dividing by 78 km:

x = 3 hours. Part 2 took 3 hours. Part 1 took 2 hours, so the whole trip took 5 hours.

Answer:

θ = 29.38°

Explanation:

The centripetal force is given by the formula;

F_c = F_n(sin θ) = mv²/r

Now, the vertical component of the normal force is; F_n(cos θ)

Now, this vertical component is also expressed as; F_n(cos θ) = mg

Thus, the slope is;

F_n(sin θ)/F_n(cos θ) = (mv²/r)/mg

tan θ = v²/rg

v² = rg(tan θ)

The initial speed will be gotten from the relation;

(v_o)² = μ_s(gr)

Plugging rg(tan θ) for (v_o)², we have;

μ_s(gr) = rg(tan θ)

rg will cancel out to give;

μ_s = (tan θ)

Thus, θ = tan^(-1) μ_s

μ_s is coefficient of static friction given as 0.563

θ = tan^(-1) 0.563

θ = 29.38°

Mass of the snow falls vertically and lands on the moving slide the speed of the slide will decrease due to friction.

It is mentioned that the friction along the icy horizontal surface and the sled is knowledgeable then it means that we cannot ignore the friction. So, when the mass of snow falls vertically from the tree on the sled when the sled passes underneath the tree it cannot be considered a elastic collision.

The kinetic energy of the system will be changed and the linear momentum will not remain constant because of the friction. It will be an inelastic collision and because the mass of the body is increasing, so, the speed of the slide will decrease when the mass of the snow will fall on the sled.

if the universe is 13.8 billion years old, how can we see 46 billion light years away because space has also been expanding?

When total distance to distant cosmic objects like galaxies is taken into account, their measurement is referred to as cosmological distance. This distance accounts for universe's ongoing expansion. Space itself stretches as a result of the universe's expansion, causing two things' distances to grow even when they are not physically moving apart.

One may observe objects that are currently positioned farther distant than the age of the universe thanks to this stretching of space. For a very long time, light emanating from these far-off objects has been travelling through space. Light has essentially travelled a greater distance than the actual physical distance between us and the object because of the universe's expansion during that time.
