THow high is the building if the time it takes for a lead weight dropped from the top of the building to fall the last 1.5 m before hitting the ground is 109s?
For the last 1.5m:s = ut + (1/2)at21.5 = ut + (1/2)*10*(109)21.5 - (1/2)*10*(109)2 = u * 109u = -545 ms-1It seems that for this situation to even exist, the lead weight must start going upwards from 1.5m at a speed greater than the speed of sound. This cannot happen if it's dropped off a building, obviously.For the situation to be believable, the time would have to be much shorter, or the distance much larger.
What is the energy of a photon with a wavelength of 550 nm?
frequency is given as f=c/L, where c is the speed of light and L is the wavelength of the electromagnetic wave. Using c=3*108 m/s, we get 3*108/(550*10-9)=545*1012Hz=545 THz Remember that Hz=1/seconds such that units fit
What is the frequency of blue light with a wavelength of 550 nanometers?
f=c/lambda frequency = 299792458 divided by wavelength The freq is in Kilohertz, and the wavelength is in meters. A nanometer is one billionth of a meter. I'll let you figure out how to move the decimals points.

How much does 545 ml weigh?
There can be no conversion.A millilitre is a measure of volume. The masses of equal volumes of the two substances will depend on the densities of the substances and so will clearly be very different. There is, therefore, no direct conversion between mass and volume. You will then need to multiply the mass by the acceleration due to gravity which is appropriate to the location in question.
