x₂ = 16 g m₂ / k. The spring's behavior adheres to Hooke's law, expressed as F = k x. For equilibrium illustrated in Newton's diagram, F - W = 0 and k x₁ = m₁ g, leading to k = g m₁ / x₁. In an elevator moving upward with acceleration, the relation adjusts to F - W = m a, which gives F = m (g + a). Compression becomes K x₂ = 4 m (g + 3g), simplifying to x₂ = 4m / k (4g) and ultimately x₂ = 16m2 / k g.
The orientation of the magnetic field and the induced current in a wire is governed by the right-hand grip rule. Given that the magnetic field is directed upwards, the thumb aligns with this direction while the fingers wrap around it. Observing from above, the current appears to flow in a counterclockwise manner.
By breaking down vector b into its x and y components, we form a right triangle where bx lies along the x-axis, by along the y-axis, and b represents the hypotenuse.
The x component bx equals the hypotenuse multiplied by the cosine of the angle between b and the x-axis, which is shown in

When Sonia rubs the balloon with a wool cloth, electrons from the balloon move to the wool because of the friction. This process causes the balloon to become positively charged. Since both balloons are treated similarly, they acquire positive charges. It’s a known principle of physics that like charges repel one another, so the two balloons will push away from each other after being rubbed with the wool.
Answer:
The peak mechanical energy transformed into internal energy throughout the descent is 26.7 joules.
Explanation:
Potential Energy (PE) is calculated as the weight of the baseball multiplied by the height, which gives us 1.47N × 10m = 14.7Nm or 14.7 joules.
The kinetic energy (KE) is recorded as 12 joules.
The maximum mechanical energy that converts to internal energy during the fall can be expressed as PE + KE = 14.7 joules + 12 joules = 26.7 joules.
