The process of charging a conductor by bringing it near another charged object and then grounding the conductor is called Induction. The correct option is C.

The process described, in which a conductor is charged by bringing it near another charged object and then grounding the conductor, is known as induction. Induction involves the redistribution of charges within the conductor without direct contact between the two objects.

Here's how the process works: When a charged object is brought close to the conductor, the charges in the conductor are rearranged.

This occurs due to the electric field of the charged object influencing the distribution of charges within the conductor. However, the conductor itself remains electrically neutral overall.

If the conductor is then grounded, allowing it to make contact with the Earth or a large reservoir of charge, any excess charges in the conductor are neutralized or redistributed, resulting in the conductor becoming charged with the opposite polarity to that of the inducing object.

Therefore, the correct term for this process is c, induction.

(a) The distance travelled by the object is  100 m.

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is 60 m.

(a) The distance travelled by the object is calculated from the total area of the curve.

total distance = area of triangle 1 + area of triangle 2 + area of rectangle.

total distance = (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

total distance = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) 20) + (10 - 0)(10 - 8)

total distance =  60 m + 20 m + 20 m

total distance = 100 m

(b) The displacement of the object in time interval between t = 0 s and t = 10 s is calculated as follows;

displacement = final position - initial position

displacement =  (¹/₂ x base x height)₁ +  (¹/₂ x base x height)₂ + length x width

displacement = (¹/₂ x 6 s x 20 m/s) +  (¹/₂ (8 - 6) (-20)) + (10 - 0)(10 - 8)

displacement = 60 m - 20 m + 20 m = 60 m

The radius of curvature of an optical system, such as a headlight, affects the divergence of the optical rays emitted by the light source. The radius of curvature is a measure of the curvature of the lens or mirror used in the optical system.

When the radius of curvature is large, the optical rays are focused into a smaller area, resulting in a narrower beam of light. This is because the light is bent more sharply as it passes through the lens or mirror, causing it to spread out less. On the other hand, when the radius of curvature is small, the optical rays are focused into a larger area, resulting in a wider beam of light. This is because the light is bent less sharply as it passes through the lens or mirror, causing it to spread out more.

The size of the light source also affects the divergence of the optical rays emitted by the headlight. The divergence of the light is a measure of how much the light spreads out as it travels away from the source. When the light source is small, the divergence is small, resulting in a beam of light that is focused and narrow. On the other hand, when the light source is large, the divergence is large, resulting in a beam of light that is spread out and wide. This is because the light has more distance to travel before it reaches the lens or mirror, causing it to spread out more.

When the lowly high diver pushes off horizontally with a speed of 2.04 m/s from the edge of a platform that is 10.0 m above the surface of the water,

(a) The diver is approximately 1.67 meters away from the edge of the platform after 0.817 seconds.

(b) The diver is approximately 6.85 meters above the surface of the water at that time.

(c) The diver strikes the water approximately 2.92 meters away from the edge of the platform.

To solve this problem, we'll use the equations of motion under constant acceleration and consider the vertical and horizontal components separately.

Given:

Initial horizontal speed (vx) = 2.04 m/s

Height of the platform (h) = 10.0 m

Time (t) = 0.817 s

Acceleration due to gravity (g) = 9.8 m/s²

(a) To find the horizontal distance from the edge of the platform after 0.817 s:

We can use the equation: distance = initial velocity × time

Horizontal distance = vx × t

Horizontal distance = 2.04 m/s × 0.817 s

Horizontal distance ≈ 1.67 m

Therefore, the diver is approximately 1.67 meters away from the edge of the platform after 0.817 seconds.

(b) To find the vertical distance above the surface of the water at that time:

We can use the equation: height = initial height + initial velocity × time + (1/2) × acceleration × time²

Vertical distance = h + 0 + (1/2) × g × t²

Vertical distance = 10.0 m + (1/2) × 9.8 m/s² × (0.817 s)²

Vertical distance ≈ 6.85 m

Therefore, the diver is approximately 6.85 meters above the surface of the water at that time.

(c) To find the horizontal distance from the edge of the platform where the diver strikes the water:

We'll consider vertical motion. The time it takes for the diver to fall from the platform to the water can be found using the equation: height = (1/2) × g × t²

Solving for time:

10.0 m = (1/2) × 9.8 m/s² × t²

t² ≈ 2.04 s²

t ≈ √2.04 s

t ≈ 1.43 s

Now, we can calculate the horizontal distance using the equation: distance = horizontal velocity × time

Horizontal distance = vx × t

Horizontal distance = 2.04 m/s × 1.43 s

Horizontal distance ≈ 2.92 m

Therefore, the diver strikes the water approximately 2.92 meters away from the edge of the platform.

Right distance = 19m

Time is taken to cover distance = 4.8s

Left distance = 12m

Time is taken to cover distance = 5s

total displacement = 19 m to the right - 12 m to the left = 7 m to the right

A. To calculate the magnitude of the average velocity, we need to find the total displacement and divide it by the total time.

The total time it took for the woodchuck to run both distances is:

The total time = 4.8 s + 5 s

The total time = 9.8 s

The magnitude of the average velocity is:

v = displacement/time

v  = 7 m / 9.8 s

v = 0.71 m/s

If the same force is applied to an object with a small mass, it will experience a greater acceleration due to less inertia and the ease with which it can be accelerated. In contrast, an object with a larger mass will require more force to achieve the same acceleration.

According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass. Mathematically, we can express this relationship as:

acceleration = force / mass

Therefore, if the same force is applied to an object with a small mass, it will experience a greater acceleration compared to an object with a larger mass. This is because the smaller mass results in less inertia, meaning it requires less force to cause a given acceleration. In other words, a smaller mass will accelerate more easily when the same force is applied to it. For example, if you apply the same force to a baseball and a bowling ball, the baseball will accelerate much more quickly because it has a smaller mass than the bowling ball. Conversely, if you apply the same force to a truck and a car, the car will accelerate more quickly because it has a smaller mass than the truck.

The hydraulic gradient (i) can be calculated by dividing the head difference (h) by the distance (L) between the manometer tappings:

i = h / L

Given:

Head difference (h) = 45 mm

Distance between manometer tappings (L) = 100 mm

Converting the units to meters:

h = 45 mm / 1000 = 0.045 m

L = 100 mm / 1000 = 0.1 m

Substituting the values into the formula:

i = 0.045 m / 0.1 m = 0.45

(ii) Flow rate:

The flow rate (Q) can be calculated using the equation:

Q = (V / t) / A

Where V is the quantity of water collected, t is the duration of the test, and A is the cross-sectional area of the test sample.

Given:

Quantity of water collected (V) = 500 ml = 0.5 L

Duration of test (t) = 300 seconds

Diameter of test sample (d) = 100 mm

Converting the units to meters:

V = 0.5 L = 0.5 / 1000 = 0.0005 m³

t = 300 seconds

d = 100 mm / 1000 = 0.1 m

Calculating the cross-sectional area (A) using the formula for the area of a circle:

A = π * (d/2)^2

Substituting the values:

A = π * (0.1/2)^2 = π * 0.005^2 = 0.00007854 m²

Substituting the values into the formula for flow rate:

Q = (0.0005 m³ / 300 s) / 0.00007854 m²

Calculating the flow rate:

Q = 0.00000167 m³/s
