When the ball on a spring is replaced by a smaller ball with half the mass : The period decrease by 29%
<h3>Calculate the Period </h3>
We will apply the formula below to calculate period
T = 
where :
T₁ / T₂ = 
where m₂ = m₁ / 2
Therefore :
T₂ = 
= 0.71 T
Hence we can conclude that the period will decrease by 29% ( i.e 100 - 71 ).

Answer: of gamma rays with high energies.
Explanation:Gamma-ray bursts are extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe.
The frequency of the most energetic bursts has been measured at around 3.0×1021 3.0 × 10 21 Hz.
The first car travels at 60km/h and skid at 30m away from the starting point while another car is also traveling at 180km/h. Now, we need to solve for the skidding distance.
We assigned variables such as:
V1=60km/h
V2=180km/h
Skid1=30m
Skid2=?
We solve this by ratio and proportion method such as shown below:
V1/V2=skid1/skid2
60/180=30/skid2
skid2=(30*180)/60
skid2=90meters
Th answer is 90 meters.
