The period of the moon's rotation on its axis is the same as its revolution around the Earth much longer than its revolution around the Earth longer or shorter depending on what part of the year we are in much shorter than its revolution around the Earth

Heat that we can feel and is measurable is called: Heat cannot be measured Illogical Latent Sensible

33. What are the two ways that light quality can be characterized? direct or indirect light bright and dim light hard and soft light round and curved light

Which of the following describes the effect of beam filtration on the x-ray spectrum? It increases the number of low-energy photons It decreases the average energy of the beam It increases the average energy of the beam It increases patient dose

What is the acceleration of a train that takes 22 seconds to go from a speed of 73 kilometers per hour to a speed of 45 kilometers per hour? $-1.3km/h/s$ $0.79km/h/s$ $-1.3km/h^{2}$ $-1.1km/h/s$ $-1.6km/hs$

A soccer player runs up behind a soccer ball (of mass 0.50 kg) that is moving at $3.5m/s$ in the same direction as the player. The soccer player kicks it and the ball moves with a speed of $13.5m/s$ What is the magnitude of the impulse (in $kgm/s)$ delivered to the soccer ball? A 5.0 B 7.5 C 10 D 15

Two Students are discussing connecting the meter to measure amperage.Student A states the meter leads should be connected in parallel with the circuit.Student B states the meter leads should be connected in series with the circuit. Who is correct? Student A only Student B only Both Student A and Student B Neither Student A nor Student B

Calculate the frequency of the green light emitted by a hydrogen atom with a wavelength of 486.1 nm. $6.86\times 10^{14}J$ $4.09\times 10^{-19}J$ $4.33\times 10^{14}J$ $4.86\times 10^{-7}J$

9. Given the formula $c=\lambda \cdot v.$ .show how you would manipulate this equation to solve for wavelength and for frequency. (Can you show the equation for just wavelength? Just frequency?) $\square $
