A 5.0 kg block hangs from a spring with spring constant 2000 N/m. The block is pulled down 5.0 cm from the equilibrium position and given an initial velocity of 1.0 m/s back toward equilibrium. What is the amplitude A, of the motion? Enter your answer in units of cm but do not include units

7.1 cm.

Explanation:

Given,

mass of the block, m = 5 Kg

Spring constant, k = 2000 N/m

moved position, x = 5 cm

initial speed,v = 1 m/s

Amplitude,A = ?

We know,

Relation between velocity, Amplitude is given by

Amplitude of the motion is equal to 7.1 cm.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
