shtirl [24]3 years ago
8 0

Answer:

As Per Given Information

Mass of Car 4000 Kg

Acceleration of car 20m/s²

we have to find the force required to make the car car accelerate at given magnitude .

Using Formulae

  • Force = Mass × Acceleration

On Putting the value we obtain

↝ Force = 4000 × 20

↝ Force = 80000 N

↝ Force = 80KN

So, the force required to maintain the given acceleration is 80 KiloNewton .

suter [353]

Balanced chemical reaction: 2KCl + Pb(NO₃)₂ → PbCl₂ + 2KNO₃.

According to principle of mass conservation, number of atoms must be equal on both side of balanced chemical reaction.  

KCl is potassium chloride.

Pb(NO₃)₂ is lead(II) nitrate.

KNO₃ is potassium nitrate.

PbCl₂ is lead(II) chloride.

The mass of a solid substance is 21.112 g. If the volume of the solid substance is 19.5 cm3, calculate the density of the substa
Ostrovityanka [42]

Answer:

ρ = 1.08 g/cm³

Explanation:

Step 1: Given data

Mass of the substance (m): 21.112 g

Volume of the substance (V): 19.5 cm³

Step 2: Calculate the density of the substance

The density (ρ) of a substance is equal to its mass divided by its volume.

ρ = m / V

ρ = 21.112 g / 19.5 cm³

ρ = 1.08 g/cm³

The density of the substance is 1.08 g/cm³.
