Wings to fly. Without flying, birds would be near defenseless.
Acceleration means speeding up, slowing down, or changing direction. The graph doesn't show anything about direction, so we just have to examine it for speeding up or slowing down ... any change of speed.
The y-axis of this graph IS speed. So the height of a point on the line is speed. If the line is going up or down, then speed is changing.
Sections a, c, and d are all going up or down. Section b is the only one where speed is not changing. So we can't be sure about b, because we don't know if the track may be curving ... the graph can't tell us that. But a, c, and d are DEFINITELY showing acceleration.

225=m (2.20m/s2 which give m=16kg I used newtons second law to fins the required average force
Complete question is;
Describe how α-radiation is similar to β-radiation?
Answer:
Explained below
Explanation:
The similarity between both alpha radiation and beta radiation is that in both cases, they both show deflection when they go through electric and magnetic fields. Although alpha deflects towards the negative plate while bets deflects towards the positive plate.
Secondly they both have high speeds. Just that alpha is from the helium nucleus while beta is from electrons.
