7 0

Answer:

D.They are equal in magnitude and opposite in direction

Explanation:

  • Newton's third law states that the action force is always associated with a reaction force.
  • When a body 'A' exerts a force on body 'B', it is called the force of action.
  • When the body 'B' in turn resist the force of 'A' is called the reaction force. It is the reactive force acted upon by the body 'B' on 'A'.
  • This reaction force is equal in magnitude of the action force.
  • If the two bodies remain in the same horizontal line, the 'A' exerts a force in the direction towards 'B' and the body 'B' exerts a reaction force in the direction towards 'A'.
  • Hence, the two forces that are exerted by the bodies are equal in magnitude and opposite in direction.

Pls help my science teacher is a horrible teacher...
Anettt [7]

First of all, looks like your teacher is indeed pretty horrible. Secondly, the constraints to consider would be proper weight distribution, methods to minimize excessive motion of the building structure, and quantities such as volume and density, which would help in determining the optimal structure. Keeping the frequency of oscillation for a building low in case of an earthquake or natural disaster would also be a priority.

the hydrometer with the density of liquid to be 800 kg metre per square is the volume of the submerged part of the hydrometer is
julia-pushkina [17]

Answer:

Mass = 0.04 Kg

Explanation:

Given the following data;

Density = 800 kg/m³

Volume = 5 * 10^{-5} m³

To find the mass of the object;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

Density = \frac {mass}{volume}

Making mass the subject of formula, we have;

Mass = density * volume

Substituting the values into the formula, we have;

Mass = 800 * 5 * 10^{-5}

Mass = 0.04 Kg

KonstantinChe [14]

Answer:

d. perfectly elastic

Explanation:

According to the kinetic theory for collisions of gas molecules:

1.The loss of energy is negligible or we can say that it is zero.

2.Molecules of the gas move in a random manner.

3.The collision between molecules and with the wall of the container is perfectly elastic.That is why loss in the energy is zero.

Therefore the correct answer will be d.

d. perfectly elastic
