Answer:
Les facteurs abiotiques font référence aux éléments physiques et chimiques non vivants de l'écosystème. Les ressources abiotiques proviennent généralement de la lithosphère, de l'atmosphère et de l'hydrosphère.
Explanation:
Answer:
1. Magnetic force = 4.56*10^-12 N
2. Acceleration = 5.01 *10^18 m/s^2
3. A) The direction of the moving electron will change but its speed will remain constant.
Explanation:
Given Data:
B = 0.0040 T North
q = 1.6*10^-19 C
Mass of electron = 9.1*10^-31 kg
V = 9.5% of speed of light
= 9.5% *3*10^8
= 28.5*10^6 m/s west
So, B and v are perpendicular to each other.
Therefore, ∅ = 90°
1, Calculating the magnetic force using the formula;
F = qvBsin∅
= 1.6*10^-19 * 28.5*10^6*sin90
= 4.56*10^-12 N
Therefore, the strength of the force = 4.56*10^-12 N
2. Calculating acceleration using the formula;
F = ma
a = F/m
= 4.56*10^-12 /9.1*10^-31
= 5.01 *10^18 m/s^2
3. A) The direction of the moving electron will change but its speed will remain constant.
