Answer:
Explanation:
Period of the pendulum will not change as the period is not a function of mass
T = 2π√(L/g)
Period of the spring oscillator will increase with larger mass because period is a function of mass.
T = 2π/ω = 2π/√(k/m) = 2π√(m/k)
All electromagnetic waves travel in vacuum (space) at the speed of light (3 * 10^8 m/s). Radio waves is just a member of the electromagnetic spectrum. All electromagnetic waves follow the wave equation: speed = frequency * wavelength. With all electromagnetic waves, the speed in space is the same.
It depends on how close you get to it. Remember that its gravity decreases as you get farther from it.
Answer:
The bimetallic strip will bend to the iron's way since
When heated copper expands more than iron
Explanation:
bimetallic strips are temperature regulatory devices used to convert a temperature change into mechanical displacement.
It consists of two layers, usually iron and copper which layers are joined together to form the strip owing to the difference in the constants of expansion of the two materials, a flat strip will bend one way (toward the iron part) if heated. The linear thermal expansion coefficient relates the change in temperature to the change in a material's linear dimensions.
Explanation:
<h2>Speed is the rate of change of distance with time.</h2>
