The answer to this question is letter C) Each student read
the meter stick from different angles.
The students might have been reading the meter stick facing
each other. So when one reads the meter stick as 18, the other student will
read the reverse image of the measurement. 18 and 82 can be easily mistaken
when reversed.
Il write down the answers of the blanks which are as follows:-
Weight
Electrical
Magnetic
Force
Newtons
Mass
Kilograms
Hope this helps!
Answer:
72 m
Explanation:
Given:
v₀ = 0 m/s
v = 60 m/s
a = 25 m/s²
Find: Δx
v² = v₀² + 2aΔx
(60 m/s)² = (0 m/s)² + 2 (25 m/s²) Δx
Δx = 72 m
==> they carry energy from one place to another;
==> their speed depends on properties of the medium;
==> they undergo reflection, refraction, diffraction, and dispersion;
==> their intensity varies as the inverse square of the distance they travel;
