It doesn't really matter how long the pendulum is now. If the clock is running too fast, then you should slightly INcrease the length of the pendulum. Short ones swing faster. Long ones swing slower.
Answer:
The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
Answer:
The First Law of Thermodynamics relates internal energy or thermal energy, heat and work. There are some important things to consider. The first law will not tell you the amount of internal or thermal energy, but only how much it has changed. Heat is not temperature. Heat is the flow of energy from hot to cold objects. If heat flows into a system, we consider it positive. If heat flows out of a system, we consider it negative. Work can be done on or by the gas. If the volume increases, the gas is doing the work and we consider this negative. If work is done on the gas, the volume decreases and we consider this positive.
The speed of the wavelength on this string 322.4 m/s.
Given,
Half wavelength = 0.65m,
So, Wavelength = 2*.65=1.3m, frequency=248Hz
Speed=wavelength*frequency=1.3*248=322.4 m/s.
<h3 /><h3>Wavelength</h3>
The wavelength, or spatial period, of a periodic wave in physics refers to the length over which the wave's structure repeats. It is the separation between neighbouring wave points that correspond to the same phase, such as two adjacent crests, troughs, or zero crossings. It is a property of both travelling waves and standing waves as well as other spatial wave patterns. The spatial frequency is the wavelength's reciprocal. The Greek letter lambda (), which represents wavelength, is frequently used. When describing modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids, the term wavelength is also occasionally used.
