Answer:
-2 m/s²
8.7 m/s
Explanation:
Using Newton's second law, the sum of forces in the x direction:
∑F = ma
-120 N = (60 kg) a
a = -2 m/s²
Given:
Δx = 6.0 m
v₀ = 10 m/s
a = -2 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (10 m/s)² + 2 (-2 m/s²) (6.0 m)
v = 8.7 m/s
Yes water is liquid.
Explanation: At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second.
Answer:
The answer to the question is 72N
The formular for calculating force is;
Force = Mass× acceleration due to gravity
therefore 6kg×12m/s/s = 72N
The first choice is the true statement.
Answer:
Variation
Explanation:
This explains variation because theres many different species in the question
