The new velocity of the 0.18 kg ball, given that it's initial velocity was 0.39 m/s is 0.37 m/s

The following data were obtained from the question:

The new velocity of the first ball (0.18 Kg) can be obtained as follow:

Momentum before = Momentum after

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(0.18 × 0.39) + (0.016 × 0.05) = (0.18 × v₁) + (0.016 × 0.26)

0.0702 + 0.0008 = 0.18v₁ + 0.00416

Collect like terms

0.18v₁ = 0.0702 + 0.0008 - 0.00416

0.18v₁ = 0.06684

Divide both sides by 0.18

v₁ = 0.06684 / 0.18

v₁ = 0.37 m/s

Thus, the new velocity of the 0.18 Kg ball is 0.37 m/s

If the children from Beijing had a demyelinating disease, the result of Dr. McKhann's conduction velocity test would likely show a slower conduction velocity.

Demyelinating diseases, such as multiple sclerosis, involve damage to the myelin sheath that surrounds nerve fibers. The myelin sheath plays a crucial role in facilitating the rapid conduction of nerve impulses. When it is damaged, the conduction of electrical signals along the nerves is slowed down.

Dr. McKhann's conduction velocity test measures the speed at which electrical signals travel along the nerves. Normally, healthy nerves with intact myelin sheaths have faster conduction velocities. However, in the case of demyelinating diseases, the damaged myelin sheath interferes with the efficient transmission of electrical signals, resulting in a slower conduction velocity.

Therefore, if the children from Beijing had a demyelinating disease, Dr. McKhann's conduction velocity test would likely indicate a slower conduction velocity compared to individuals without the disease. This result would provide important evidence of the presence of a demyelinating disease in the children.

Terrestrial planets are thought to have dense iron cores primarily due to their formation process and the differentiation of their materials.

During the early stages of planet formation, when dust and gas in a protoplanetary disk come together to form planets, heavier elements such as iron tend to sink towards the center due to their higher density. This process, called planetary differentiation, results in the formation of a dense metallic core at the center of the planet. Iron is one of the most abundant heavy elements in the universe, and its high density makes it more likely to sink towards the core during planetary formation. As the planet grows and accumulates more material, the iron-rich core becomes more prominent.

When a white dwarf supernova occurs, it typically reaches its peak brightness within a matter of days. This peak brightness can be incredibly intense, with some white dwarf supernovae becoming billions of times brighter than the sun.

This brightness does not last long. Within a matter of weeks, the supernova will begin to decline in brightness, eventually fading to 10% of its peak brightness. The exact amount of time this takes can vary depending on a number of factors, including the size and mass of the white dwarf, the amount of material it is consuming, and the environment in which it is located. However, in general, most white dwarf supernovae will reach this 10% point within a few weeks to a few months of their peak brightness. After this point, the supernova will continue to fade, eventually becoming too dim to be seen with even the most powerful telescopes. It is worth noting that while white dwarf supernovae are incredibly bright, they are relatively rare events. Scientists estimate that they occur only once every few hundred years in our own galaxy, making them a fascinating but difficult phenomenon to study. Nonetheless, by analyzing the light and other signals emitted during these events, scientists hope to gain a better understanding of the complex processes that occur during these explosive cosmic events.

To answer this question, the tangential speed of the bob must be calculated. The formula for tangential speed is v = rω, where r is the radius of the circle and ω is the angular velocity.

To calculate the angular velocity, we must use the formula ω = θ/t, where θ is the angle from the vertical and t is the time it takes for one complete revolution of the bob around the circle.
Once we have the angular velocity, we can plug it into the formula for tangential speed. Thus, the tangential speed, v, for the bob must be v = rω, where r is the radius of the circle and ω is the angular velocity which is equal to ω = θ/t, where θ is the angle from the vertical and t is the time it takes for one complete revolution of the bob around the circle.
