Scholar ISIAH was searching for his favorite hip hop song on a certain FM radio station known as 105.1. He approached a Physics Professor at York College and found out that this station broadcasts electromagnetic waves at a frequency of 9.05 X 107 Hz and the radio waves travel at a speed of 3.00 X 108 m/s. He wanted to know the specific wavelength of these radio waves? The wavelength is

Galileo was the first to notice that the moon has craters, valleys, and mountains. how might this have changed people's perception of the moon at the time?

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).
