Answer:
The frequency of the wave is 5.0Hz
Explanation:
The frequency of a wave is the number of oscillations or revolutions made in a second.
Answer:
The work done by the force on the particle is 29.85 J.
Explanation:
The work is given by:
![W = ^{x_{2}}_{x_{1}}\int F_{x} dx](https://tex.z-dn.net/?f=%20W%20%3D%20%5E%7Bx_%7B2%7D%7D_%7Bx_%7B1%7D%7D%5Cint%20F_%7Bx%7D%20dx%20)
Where:
x₁: is the lower limit = 0 m
x₂: is the upper limit = 1.9 m
Fₓ: is the force in the horizontal direction = (4.5 + 13.7x - 1.5x²)N
![W = 29.85 J](https://tex.z-dn.net/?f=W%20%3D%2029.85%20J)
Therefore, the work done by the force on the particle is 29.85 J.
I hope it helps you!
Answer: The variable that you manipulate is called the independent variable. The variable that you measure is called the dependent variable.
The answer is D. For instance, Sir Issac Newton believed that light was made up of tiny particles that acted wave like. In conclusion, the answer is D. Sir Issac Newton.
Answer:
Elastic collision
Explanation:
The interaction of two particles is called collision. There are two types of collision i.e. elastic collision and inelastic collision.
Two bouncy balls colliding with each other is an example of elastic collision. In this type of collision the momentum and kinetic energy of the bodies remains constant i.e.
![m_1u_1+m_2u_2=m_1v_1+m_2v_2](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3Dm_1v_1%2Bm_2v_2)
and
![\dfrac{1}{2}m_1u_1^2+\dfrac{1}{2}m_2u_2^2=\dfrac{1}{2}m_1v_1^2+\dfrac{1}{2}m_2v_2^2](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7Dm_1u_1%5E2%2B%5Cdfrac%7B1%7D%7B2%7Dm_2u_2%5E2%3D%5Cdfrac%7B1%7D%7B2%7Dm_1v_1%5E2%2B%5Cdfrac%7B1%7D%7B2%7Dm_2v_2%5E2)
Where
m₁ and m₂ are masses of two balls A and B
u₁ and u₂ are initial velocities of ball A and B
v₁ and v₂ are final velocities of ball A and B
