The correct Answer is:
To solve the question, we need to analyze the effects of striking a key on a mechanical piano with different intensities. Here’s a step-by-step breakdown: ### Step 1: Understand the scenario The question describes two instances of striking the same key on a mechanical piano: first gently and then much harder. ### Step 2: Identify the key concepts - **Loudness**: This is related to the intensity of the sound. Striking the key harder increases the intensity, which results in a louder sound. - **Pitch**: This is determined by the frequency of the sound waves produced. Since the same key is struck in both instances, the pitch remains unchanged. ### Step 3: Analyze the first strike When the key is struck gently, it produces a sound of lower intensity, resulting in a softer sound. ### Step 4: Analyze the second strike When the key is struck much harder, the intensity of the sound increases, leading to a louder sound. However, because the same key is used, the frequency of the sound waves does not change, and thus the pitch remains the same. ### Step 5: Conclusion Based on the analysis: - The sound will be louder when struck harder. - The pitch will remain the same since the same key is used. Therefore, the correct answer is that the sound will be louder, but the pitch will not be different. This corresponds to option 1. ### Final Answer **The correct answer is: Sound will be louder, but pitch will not be different (Option 1).** ---

A student is running at her top speed of 5.0 m s^(-1) , to catch a bus, which is stopped at the bus stop. When the student is still 40.0m from the bus, it starts to pull away, moving with a constant acceleration of 0.2 m s^(-2) . a For how much time and what distance does the student have to run at 5.0 m s^(-1) before she overtakes the bus? b. When she reached the bus, how fast was the bus travelling? c. Sketch an x-t graph for bothe the student and the bus. d. Teh equations uou used in part (a)to find the time have a second solution, corresponding to a later time for which the student and the bus are again at thesame place if they continue their specified motions. Explain the significance of this second solution. How fast is the bus travelling at this point? e. If the student s top speed is 3.5 m s^(-1), will she catch the bus? f. What is the minimum speed the student must have to just catch up with the bus?For what time and what distance dies she have to run in that case?

A spring, which is initially in its unstretched condition, is first stretched by a length x and then again by a further length x. The work done in the first case is W_(1) and in the second case is W_(2) .

Starting from rest a particle is first accelerated for time t_1 with constant acceleration a_1 and then stops in time t_2 with constant retardation a_2. Let v_1 be the average velocity in this case and s_1 the total displacement. In the second case it is accelerating for the same time t_1 with constant acceleration 2a_1 and come to rest with constant retardation a_2 in time t_3. If v_2 is the average velocity in this case and s_2 the total displacement, then

A particle performing simple harmonic motion having time period 3 s is in phase with another particle which also undergoes simple harmonic motion at t=0 . The time period of second particle is T (less that 3s). If they are again in the same phase for the third time after 45 s, then the value of T will be

A horizontal frictionless rod is threaded through a bead of mass m . The length of the cart is L and the radius of the bead, r , is very small in comparison with L(r lt lt L) . Initially at ( t = 0 ) the bead is at the right edge of the cart. The can is struck and as a result, it moves with velocity v_(0) towards right. When the bead collides with the cart's walls, the collisions are always completely elastic. The first collision takes place at time ti and the second collision takes place at time t_(2) . Find t_(2)-t_(1)

A circular ring of small thickness and of inner and outer diameters 3.8 cm and 4.2 cm respectively , suspended on one side of a common balance is exactly balanced by keeping sufficient mass in the pan on other side .At this instant the lower surface of ring is just resting on the surface of a liquid . Now if the ring is puled up gently , such that it does not loose its contact with the liquid , find how much mass should be changed in other pan , again to keep the balance in balanced position ? (Assume angle of contact is zero and surface tension of liquid is (1 //pi) N/m)

A particle of mass m and charge q is accelerated by a potential difference V volt and made to enter a magnetic field region at an angle theta with the field. At the same moment, another particle of same mass and charge is projected in the direction of the field from the same point. Magnetic field induction is B. What would be the speed of second particle so that both particles meet again and again after regular interval of time. Also, find the time interval after which they meet and the distance travelled by the second particle during that interval.
