Answer:

0.4 N

Explanation:

The weight mg is 8 N, so the mass is:

mg = 8 N

m = 8 N / g

m = 8 N / (10 m/s²)

m = 0.8 kg

The force needed to accelerate it to 0.5 m/s².

F = ma

F = (0.8 kg) (0.5 m/s²)

F = 0.4 N

Answer:

it is below pls give 5 star

Explanation:

Foods contain stored potential energy in the form of chemical energy. When we consume food, the particles undergo a chemical reaction that releases the chemical energy. In turn, this energy is used by the body to perform its daily activities.

Therefore, when you eat a bowl of vegetable soup, you get the chemical energy that is stored in it.
