Answer:
An object’s weight is proportional to its mass.
Answer: Kinetic theory or kinetic theory of gases attempts to explain overall properties of gases, such as pressure, temperature, or volume, by considering their molecular composition and motion. The theory basically states that pressure is not caused by molecules pushing each other away, like earlier scientists thought.
Explanation:
Well the diagram would look like the water cycle I think
Answer:
Black Flies, leeches and aquatic worms.
Explanation:
Black Flies, leeches and aquatic worms are the organisms that are tolerant to pollution and has the ability to survive in the polluted environment occur due to man-made waste. these organisms sometimes takes food from these pollutants and help in surviving these organisms. Without these tolerant organisms, those organisms which are not sensitive to these pollutants will die and removed from that polluted environment.
We have to assume that the truck was not moving
before he started pushing it.
After he did 12 J of work pushing it, the truck had
12 J of kinetic energy.
Kinetic energy = (1/2) (mass) (speed²)
12 J = (1/2) (3 kg) (speed²)
Divide each side by 1.5 kg : 12J / 1.5 kg = speed²
1 J = 1 newton-meter (12 kg-m²/sec²) / (1.5 kg) = speed²
= 1 kg-m² / sec²
(12 / 1.5) ( m²/sec²) = speed²
Speed = √(8 m²/s²)
Speed = 2.83 m/s .
We can't say anything about velocity, because we don't know
anything about the direction in which the truck is moving.
