Laser transmissions travel at a higher speed than the radio waves true or false

Physics
1 answer:
uranmaximum [27]3 years ago
6 0
<span>False. Laser transmissions and radio waves are both forms of electromagnetic radiation. Both travel at approximately 3.00 x 10^8 meters per second. This is the case because wavelength and frequency are directly proportional to this value. Although laser light has a shorter wavelength than radio waves, it will travel at the same speed because the frequency will be greater.</span>

Using this formula Q = mcAt. A 1kg block of aluminum is increased in temperature by 75°C. how much heat energy was required? a 6
scZoUnD [109]

Answer:

67500 J

Explanation:

Q = mcΔt.................... Equation 1

Where Q = Amount of heat, m = mass of aluminum, c = specific heat capacity of aluminium, Δt = change or increase in temperature.

From the question,

Given: m = 1 kg, Δt = 75 °C

Constant: c = 900 J/kg.K

Substitute these values into equation 1

Q = 1×900×75

Q = 67500 J

Hence the heat energy required is 67500 J
