A 222 N force is required to keep an object moving along a circular path with a diameter of 11.6 m at a speed of 7.60 m/s. What
Arte-miy333 [17]

Answer:

m=22.3\ kg

Explanation:

The expression for centrifugal force is shown below as:-

F=\frac{m\times v^2}{r}

Where, m is the mass of the object = ?

v is the velocity of the object = 7.60 m/s

r is the radius

F is the force = 222 N

Diamter = 11.6 m

Radius = d/2 = 11.6 m/2 = 5.8 m

Applying the values in the above expression as:-

222=\frac{m\times {7.60}^2}{5.8}

57.76m=1287.6

m=22.3\ kg

What coefficient should go in front of the hydrogen peroxide (H2O2 ) molecule to make the chemical equation balanced? ___ H2O2 ➞
GarryVolchara [31]

Answer:

2

Explanation:

H2O2 ➞ 2 H2O + O2

The reaction is currently not balanced because the number of atoms on the reactant side is not equal to that of the product side

Hydrogen

Reactant = 2 Product = 4

Oxygen

Reactant = 2 Product = 4

Adding 2 to H2O2 balances the reaction as the number of atoms of both elements are now balanced on both sides of the equation

2H2O2 ➞ 2 H2O + O2
