Frequency is the inverse of the time period. The frequency of the wave will be 0.02.
Frequency is defined as the number of cycles per second. The time to make one complete cycle is frequency.
Frequency = 1 / period
F= 1 / T
F=1/50 sec
F=0.02 Hz.
Hence, the frequency of the wave will be 0.02.

Answer:
A magnetic force can convert kinetic energy stored in a magnetic field to potential energy. Kinetic energy can convert potential energy stored in a gravitational field. A magnetic energy can convert potential energy stored in a gravitational field to kinetic energy.
component equal to 5 m/s and a vertical component
equal to 6 m/s.
At the highest point of the projectile's flight, what is (a) the horizontal component of its
velocity and
(b) the vertical component of its velocity?
Explain.
The horizontal component of a projectile's velocity remains constant throughout its flight. Hence, at the highest point, its value is the same as the initial, 5 m/s. The vertical component, on the other hand, becomes zero at the highest point.
For a projectile, the horizontal component of motion and the vertical component of motion are independent. Therefore, the horizontal component of velocity remains constant throughout the flight as long as there is no air resistance. Hence, at the highest point of a projectile's flight, the horizontal velocity (a) remains the same, i.e., 5 m/s.
However, for the vertical component, it is subjected to the acceleration due to gravity. At the highest point, the vertical component of velocity (b) becomes zero, because it has momentarily stopped before changing direction and accelerating downwards.

Answer:Consider again the cannonball launched by a cannon from the top of a very high cliff. Suppose that the cannonball is launched horizontally with no upward angle whatsoever and with an initial speed of 20 m/s. If there were no gravity, the cannonball would continue in motion at 20 m/s in the horizontal direction. Yet in actuality, gravity causes the cannonball to accelerate downwards at a rate of 9.8 m/s/s. This means that the vertical velocity is changing by 9.8 m/s every second. If a vector diagram (showing the velocity of the cannonball at 1-second intervals of time) is used to represent how the x- and y-components of the velocity of the cannonball is changing with time, then x- and y- velocity vectors could be drawn and their magnitudes labeled. The lengths of the vector arrows are representative of the magnitudes of that quantity. Such a diagram is shown below.

To solve this we assumethat the gas inside the balloon is an ideal gas. Then, we can use the ideal gasequation which is expressed as PV = nRT. At a constant pressure and number ofmoles of the gas the ratio T/V is equal to some constant. At another set ofcondition of temperature, the constant is still the same. Calculations are asfollows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 = 308 K x 556 cm³ / 278 K
V2 = 616 cm³
