In conclusion, the experiment aimed to determine the acceleration due to gravity by measuring the period of a simple pendulum. The experiment was performed by measuring the length of the pendulum and recording the time for 10 oscillations. The data was then used to calculate the average period and subsequently, the acceleration due to gravity using the formula: g = (4π²L)/T².

Based on the results obtained, the acceleration due to gravity was found to be (9.79 ± 0.06) m/s², which is in good agreement with the accepted value of 9.81 m/s². The small discrepancy could be due to the experimental errors such as air resistance, friction and measurement errors.

Overall, the experiment was successful in determining the acceleration due to gravity using a simple pendulum and demonstrated the relationship between the period and the length of the pendulum.

If we want to burn a paper by focusing sunlight then we have to use a converging lens that can converge all sunlight at a point called the focus.

Thus Convex lens is used to burn the paper.

The transmissive optical device known as a lens employs refraction to focus or disperse a light beam. While a compound lens is made up of numerous simple lenses (elements), they are typically oriented along a common axis, as opposed to a simple lens, which is made up of a single transparent piece. Materials like glass or plastic are used to create lenses, which are then polished, ground, or molded into the desired shape. Unlike a prism, which refracts light without concentrating, a lens can focus light to create an image. Lenses are also used to describe instruments that focus or scatter waves of radiation other than visible light, such as explosives, microwaves, and electron lenses.

a) The magnitude of the force that the string tension exerts on the airplane varies at different points of the trajectory due to the changing direction and speed of the airplane. When the airplane is at the beginning of its trajectory, the force of string tension is at its highest.

This is because the airplane is being pulled forward by the tension in the string, which opposes the backward force of air resistance. As the airplane moves along its trajectory, the magnitude of the string tension force decreases because the airplane gains speed and experiences less resistance. At the midpoint of the trajectory, the string tension force is at its minimum as the airplane reaches its maximum speed. Finally, as the airplane reaches the end of its trajectory, the magnitude of the string tension force increases again as the airplane slows down and the air resistance force becomes more significant.

b) The magnitude of the sum of the forces (the net force) exerted on the airplane varies at different points of the trajectory due to the balance or imbalance of the forces acting on the airplane. At the beginning of the trajectory, when the airplane is starting to move, the net force is not zero.

It is equal to the difference between the force of string tension and the force of air resistance. As the airplane gains speed and reaches the midpoint of the trajectory, the net force becomes zero because the force of string tension equals the force of air resistance. At this point, the airplane is moving at a constant speed. Finally, as the airplane reaches the end of its trajectory and slows down, the net force becomes nonzero again, with the force of air resistance exceeding the force of string tension.

In summary, the magnitude of the force that the string tension exerts on the airplane and the magnitude of the sum of the forces exerted on the airplane vary at different points of the trajectory due to changes in speed, direction, and the balance of forces.

The resultant vector is 60.2 meter in a direction 48.6° North of west.

Resultant vectors are the product of the addition of two or more vectors.

The resultant vector is obtained by vector addition methods such as:

Considering the vector addition problem given:

Harry travels 40 meters east and then 45 meters south to catch the snitch in a quidditch match. At the same time, Voldemort who was 40 meters away, came racing 30 meters west towards Harry, then he went south of west at 25 degrees crashing into harry.

The resultant vector of both Harry and Voldemort are the same since the crashed into each other.

Using Harry's movement, the motion forms a right angle triangle of sides 40 m and 45 m

Using Pythagoras' rule:

R = √(40² + 45²)

R = 60.2 meter

α = tan⁻¹(40/45)

α = 41.6

θ = 90 - 41.6

θ = 48.6°

Answer:

Explanation:

The maximum height reached by the ball is 1042.9 m and the range of the ball is 543.98 m.

The given problem can be solved using projectile motion. Projectile motion is a form of motion that occurs when an object is thrown near the surface of the earth and moves along a curved path due to the influence of gravity. Here, a ball is thrown into the air at an angle of 70 degrees above the horizontal with an initial velocity of 60 m/s from a 50 m high building. We need to find the maximum height reached by the ball and the range of the ball.

Let's first find the time taken to reach the maximum height. We know that,Initial vertical velocity

u = usinθ

= 60sin70°

= 57.66 m/s

Acceleration due to gravity g = 9.8 m/s²

Maximum height h is given by the formula,

h = u²sin²θ/2g

= 57.66²sin²70°/2×9.8

= 1042.9 m

Now, we can find the time taken to reach the maximum height using the formula

v = u + gt0

= v - u/g

= 0 - 57.66/9.8

= 5.87 s

So, the time taken to reach the maximum height is 5.87 s.

Using the formula, Range

R = u²sin2θ/g

= 60²sin2(70°)/9.8

= 543.98 m

Therefore, the maximum height reached by the ball is 1042.9 m and the range of the ball is 543.98 m.

Answer:

ans: 6 m/s

Explanation:

spaceship 1 has mass= 150kg

initial momentum of spaceship 1 = 900 kg•m/s

we know,

momentum = mass × velocity

so,

velocity = momentum/mass

= 900 / 150

= 6 m/s

since we know it was initial momentum so, velocity is initial speed,

As can be shown, mass has no bearing on an object's centripetal acceleration; as a result, the centripetal acceleration is unaffected by changes in mass.

The rate at which velocity changes is known as acceleration. Acceleration typically indicates that the speed was changing, but not necessarily. An item that is moving in a circle while maintaining a constant speed is still accelerating because of direction of its motion is shifting.

An object's velocity may alter depending on whether it is moving faster, slower, or in a different direction. A falling apple, the sun orbiting the earth, or a car stopped at a stop sign are a few instances of acceleration.

Answer:

Acceleration

Explanation:

For example, if the acceleration is zero, then the velocity-time graph is a horizontal line (i.e., the slope is zero). If the acceleration is positive, then the line is an upward sloping line (i.e., the slope is positive).

The total time taken by the object to reach point C from point A is total time taken = 4.0 s

Given, A, B and C are three successive points on a straight line AB=6.0 m and BC=10.0 m. A small object moving along this line from rest with uniform acceleration passes B, and C, 2.0 s and 4.0 s respectively of passing A. We need to calculate the acceleration, velocity, distance covered and the time taken in getting C.1. Acceleration: Let a be the acceleration of the object. The velocity of the object at point B, vB = a × 2 s [as the object passes B in 2 seconds from A]The velocity of the object at point C, vC = a × 4 s [as the object passes C in 4 seconds from A]From the first equation of motion, we have: vB = u + a t Where u is the initial velocity of the object. As the object is moving from rest,u = 0vB = a × 2 s = 2a => a = vB / 2Substituting the values, a = 10/2 = 5 m/s²

Therefore, the acceleration of the object is 5 m/s²2. Velocity: From the equation of motion, vC = u + a t Where u is the initial velocity of the object. As the object is moving from rest,u = 0vC = a × 4 s = 4 × 5 = 20 m/s Therefore, the velocity of the object when it reaches point C is 20 m/s.3. Distance covered: The distance covered by the object from point A to point B is 6.0 m. The distance covered by the object from point B to point C is 10.0 m. Therefore, the total distance covered by the object is 6 + 10 = 16 m4. Time taken to reach point C:The time taken by the object to reach point B from A is 2.0s The time taken by the object to reach point C from A is 4.0 s Therefore, the time taken by the object to reach point C from point B is: time taken = 4.0 s - 2.0 s = 2.0 s Therefore, the total time taken by the object to reach point C from point A is total time taken = 4.0 s
