Answer:

2H2 + O2 = 2H2O

Explanation:

To balance the equation, you must place coefficients behind the element and have equal amounts of atoms on both sides. In this case, to balance the equation, it would read:

Determine the kinetic energy of a 150 kg roller coaster car that is moving with a speed of 15 m/s
morpeh [17]

Answer:

K.E = 19125 j

Explanation:

Given data:

Mass = 150 Kg

Speed of car = 15 m/s

K.E = ?

Solution:

Formula:

K.E = 1/2 (mv²)

K.E = Kinetic energy

m = given mass

V = speed

now we will put the values in formula.

K.E = 1/2 (mv²)

K.E = 1/2 (150 Kg) (15²)

K.E = 1/2 150 Kg × 225 m²/s²

K.E = 0.5 × 225 m²/s² ×150 Kg

K.E = 19125 j

Liquid does not act that a solid. how is it different from a solid and gas?
Wittaler [7]
Unlike solid matter, where particles are tightly packed and slightly vibrating, or gas, where particles go around everywhere and are extremely loose, a liquid has particles that are loosely packed but are still in slight contact with each other. Hope that's good enough
