Answer:
When the object is placed between F and O of a convex lens, the lens forms an erect and enlarged image.
Explanation:
The skier's speed at time <em>t</em> is
<em>v</em> = (23 m/s²) <em>t</em>
To reach a speed of 9.3 m/s, the skier would need
9.3 m/s = (23 m/s²) <em>t</em>
<em>t</em> = (9.3 m/s) / (23 m/s²)
<em>t</em> ≈ 0.404 s
Answer: When a liquid substance is poured into a vessel, it takes the shape of the vessel, and, as long as the substance stays in the liquid state, it will remain inside the vessel. Furthermore, when a liquid is poured from one vessel to another, it retains its volume (as long as there is no vaporization or change in temperature) but not its shape.
Explanation: A solid has a definite shape and volume. A liquid has a definite volume, but takes the shape of its container. A gas lacks either a defined shape or volume. Plasma is similar to a gas in that its particles are very far apart, but a gas is electrically neutral and plasma has a charge.
Answer:
A charged object in an electric field experiences a force due to the field. The electric field strength, E, at a point in the field is defined as the force per unit charge on a positive test charge placed at that point.
