Answer:
false you balance by having the same number of atom on the reactants side and the products side
ex: 1N2 + 3H2 -----> 2NH3
reactants on the left and the product is on the right
xplanation:
FORCES HAVE STRENGTH AND DIRECTION
Answer:
therefore critical angle c= 69.79°
Explanation:
Canola oil is less dense than water, so it floats over water.
Given 
which is higher than that of water
refractive index of water 
to calculate critical angle of light going from the oil into water
we know that

now putting values we get

c= 
c=69.79°
therefore critical angle c= 69.79°
Answer:
4.4×10⁻⁷ Coulomb
Explanation:
V = Voltage = 5.8 kV
d = Potential distance = 2.8 mm = 0.0028 m
A = Area = 0.3×0.08 = 0.024 m²
ε₀ = permittivity constant in a Vacuum= 8.85×10⁻¹² F/m

Magnitude of charge transferred between a carpet and a shoe is 4.4×10⁻⁷ Coulomb.
No, speed is not a vector. it is scalar.
because it doesn't need direction but need magnitude.
