Answer:
D- lower central air pressure
Answer:
Wind is caused by differences of pressure in the Earth's atmosphere. Air from a high pressure area will move towards an area of low pressure. High winds are caused when air moves between areas with large differences in air pressure.
Explanation:
Explanation:
Given parameters:
Wavelength of photon = 1nm = 1 x 10⁻⁹m
Unknown:
Energy of the photon = ?
Type of radiation = ?
Solution:
The energy of a photon can be derived using the expression below:
E =
h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s
c is the speed of light = 3 x 10⁸m/s
Insert the parameters and solve;
E =
E = 1.98 x 10⁻¹⁸J
Type of radiation:
X-rays
Answer: Balance (B.)
Explanation:
Balances are used to measure mass.
Beakers and graduated cylinders measure volume. Stopwatches measure time. Meter sticks measure length. Thermometers measure temperature.
