The frequency of oscillation of a spring-block simple harmonic oscillator is given by f = 2 . such an oscillator composed of a 1 kg block attached to a wall via a spring of stiffness k = 100 n/m starts in equilibrium. a blow from a hammer then sets the block moving inward at a speed of 5 m/s. which of the following best approximates the period and amplitude of the resulting oscillations? a. t= 1.6 s, a = 50 cm b. t= 1.6 s, a = 12.5 cm ° c. t= 0.6 s, a = 50 cm 0 d. t= 0.6 s, a = 12.5 cm

Nova: secrets of the sun - video guide worksheet due tomorrowfront side (photo up top)back side (below of the following)1) a mass ejection is a wave of billions of tons of electrically charged particles.2) the sun is so huge, a earths could fit inside of it.3) the surface of the sun seems to vibrate because the sun generates waves4) using geoseismology or helioseismology, we can see the physical process under the sun's surface.5) the thickest layer of plasma in the sun is a region called the zone.6) the thinner plasma in the convection zone makes the move in a more ordered way.7) rising and sinking plasma created a mesmerizing structure called 8) the sdo revealed tornadoes or volcanoes, hundreds of miles high, on the surface of the sun9) sdo allows scientists to see sunlight across a range of 10) the earth's field protects us against threats from the sun.11) the plasma layers beneath the surface act as a which gets denser towards the core. 12) can light up along the paths of the magnetic field, making them visible. 13) the sun's the corona, is made of plasma that reaches over 3 million degrees.14) a sun spot is dark because it is cooler or warmer than its surroundings15) magnetic outbursts are more common during the period called solar
