Answer:
0.37sec
Explanation:
Period of oscillation of a simple pendulum of length L is:
T
=
2
π
×
√
(L
/g)
L=length of string 0.54m
g=acceleration due to gravity
T-period
T = 2 x 3.14 x √[0.54/9.8]
T = 1.47sec
An oscillating pendulum, or anything else in nature that involves "simple harmonic" (sinusoidal) motion, spends 1/4 of its period going from zero speed to maximum speed, and another 1/4 going from maximum speed to zero speed again, etc. After four quarter-periods it is back where it started.
The ball will first have V(max) at T/4,
=>V(max) = 1.47/4 = 0.37 sec
Answer:
Nope!
Explanation:
The amplitude of a wave does not affect the speed at which the wave travels. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

Answer:
c. frequency
Explanation:
Frequency refers to t<u>he flow at which a vibration develops into a wave</u>. Moreover, frequency is typically measured per second, and it can occur in a material like sound waves or in an electromagnetic field, such as radio waves and light. As a result, the sound mixer can exclude unwanted vibrations that turn into sound waves.
The angle the velocity of the electron make with the magnetic field is sin(∅) = 90° answer.
The equation F = qv X B may be damaged down into two elements, the significance and the path. The importance is given by F = qv B sin(∅),
Magnetic field = 1. 25-tesla
F = qv B sin(∅)
= sin(∅) = F/qv B
sin(∅) = qv X B/qv B
sin(∅) = 90° answer.
The most importance of the magnetic pressure appearing at the electron whilst its velocity v is perpendicular to B i.e magnetic discipline. The route of the force acting on the electron is the course the palm of the left hand faces. The path of the magnetic area, the direction of the transferring rate, and the route of the pressure on the particle are all perpendicular to each other.
