Answer:
the answer is moss
Explanation:
moss is a low growing plant without roots and thin cell walls
All of the answers apply because any object can have positive, negative or neutral charges depending on their atoms
Answer
Vernier caliper measure nearest to 0.01 mm.
If the correct reading of the experiment is 9.62 mm.
But you misread it and listed it as 8.62 mm.
This is Clearly the case of mistake in Accuracy.
Because the reading is wrong and answer is not accurate hence it is mistake in accuracy.
To Judge weather the reading is precise or not we should have a range where the result is acceptable but in the question no range is given. So, we cannot comment on precision.
The true velocity is 250 km/h.
Explanation:
As the aircraft is moving with speed of 300 km/h and the wind velocity is in east direction with the magnitude of 60 km/h. The resultant velocity or the true velocity can be found by the vector addition of the velocities.
If the true velocity is represented as V and the velocity of aircraft is represented as vₐ and the velocity of wind as vₓ, then
V² = vₐ² + vₓ² - vₐ.vₓ cosθ
So, the angle formed between them is 30°
Then, V² = (300)² + (60)² - 2×(300×60) cos 30°
V²=90000+3600-31177=62423
V =250 km/h
So, the true velocity is having magnitude of 250 km/h.
Thus, the true velocity is 250 km/h.
Im not 100% sure but I beleive the answer is :Because different celestial body's form different shapes and sized of comets and meterors
