I believe
the answer is C. 0.14cm.
The zero error in vernier caliper is read by the distance by which the zero of the movable part of the scale is shifted from the zero of the cm ruler in the tool, which is the unmovable part of the tool. The movable part has a scale accuracy of 0.1 cm, while the other has a scale accuracy of 1 cm. And we always use the lowest scale, which is here the 0.1 scale which has greater accuracy with 10 times the 1 cm ruler, to find our errors.

Answer:
Speed of the electron will be
Explanation:
We have given that charge on electron
Mass of electron
Potential difference =
Now according to energy conservation
Answer:
Because they need more energy.
Explanation:
Stars fuse elements in the first place to get energy. In turn, this makes the elements heavier.

Answer:
The weight of the probe is 50 Newtons
Explanation:
Newtons second law states that F = ma
Given the mass of 25kg, and the acceleration of 2m/s^2, we can substitute both values into the equation to find the weight force.
The weight of the probe is 50 Newtons
