One fine summer day a group of students was jumping from a railroad bridge into the river below. They stepped off the bridge wit

h an acceleration (due to gravity) of 9.8 m/s2 and they hit the water 1.5 s later. How high (in meters) was the bridge? Only enter the number, not the units.

Answer:

11 m

Explanation:

The following data were obtained from the question:

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) = 1.5 s

Height (h) =..?

The height of the bridge can be obtained by using the following formula:

h =½gt²

h = ½ × 9.8 × 1.5²

= 4.9 × 2.25

= 11.025 ≈ 11 m

Thus, the height of the bridge is approximately 11 m

Which type of electromagnetic radiation is responsible for the colors of<br> objects?
Svetllana [295]

Visible light or electromagnetic radiation within 400nm to 700nm is responsible for colour of the spectrum.

Explanation:

The electromagnetic spectrum contains radiations of varying wavelength. The radiations with the lowest energy are characterised by the longest wavelength.

Within this spectrum lies the visible light which enables us to see a different colour. The radiations within the range 400nm to 700nm are included in the visible spectrum.

While violet lies at the 400nm spectrum part red colour lies at 700nm part. As the wavelength of the radiation transverses between 400-700 nm, the colour of the object changes accordingly.

What is the latent heat of vaporization for water
natulia [17]

When a material in liquid state is given energy, it changes its phase from liquid to vapor; the energy absorbed in this process is called heat of vaporization. The heat of vaporization of water is about 2,260 kJ/kg, which is equal to 40.8 kJ/mol. The vaporization is the opposite process of condensation.

Explain why ice cubes formed from water of a glacier freeze at a higher temperature than ice cubes
ahrayia [7]
Because icebergs contains more molecules, and tempature measures. Heat is the energy of that motion. So there forward because there are more molecules in a iceberg then a ice cube
