The answer to this question is the first choice. In the hydrogen fusion process, the first step involves the collision of two protons to emit an antielectron and a neutrino. Only the first choice of
1_1H + 1_1H →2_1H + e^+ + v + energy
reflects this process. A hydrogen ion with a mass of one and number protons of 1 means a proton.

A, yes because the plane is using air resistance and acceleration is increasing while it goes up. Although you don’t know speed, still yes.
Answer:
0.2m/s2
Explanation:
acceleration= change in velocity ( in this case speed)/ change in time.
4.5-3.5=1m/s
change in time=5-0 =5
1m/s divided by 5 seconds acceleration as the result
Answer:
Acceleration (a) is defined as the rate of change of velocity. Velocity is a vector quantity, and therefore acceleration is also a vector quantity. The SI unit of acceleration is metres/second2 (m/s2).
