Answer:
Power is a scalar quantity and has a unit,a magnitude(a numerical value) but no direction.
Explanation:
The chemical bonds alow it to pass to the other object.
Answer:
26.6 m/s
Explanation:
Given:
Δy = 2.1 m
t = 5.35 s
a = -9.8 m/s²
Find: v₀
Δy = v₀ t + ½ at²
(2.1 m) = v₀ (5.35 s) + ½ (-9.8 m/s²) (5.35 s)²
v₀ = 26.6 m/s
Answer:
mass of the products
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the <u>mass of the products </u>in a chemical reaction must equal the mass of the reactants.
Answer:
Explanation:
Magnitude of tension
= centripetal force
= m ω²R
= m (2π/T)² R , T is time period of revolution.
= .085 x (2 x 3.14 / .55)² x .84
= 9.3 N .
