a)Gamma
Explanation:
Gamma rays are chargeless. So they cannot be deflected by electric or magnetic fields
***elements become less electropositive and more electronegative in their properties...
The radiation that was emitted is still "visible"
The universe is still expanding
Dark matter could only be crated by an atomic collapse big enough to create or destroy a universe
Answer:
To go from 20.0 to 30.0 m/s, that is a velocity change of 10.0 m/s.
From the definition of acceleration,
a = (velocity change)/(time required)
In this case you know that a = 5.0 m/s^2, so
time = (10.0 m/s)/(5.0 m/s^2)
= 2.0 seconds
OK. My heart is pounding, but I'm as ready as I'll ever be. Let 'em rip !
