Answer:
false
Explanation:
Resultant is a force with the combined effect of two or more forces. Even though a force is a vector, it is not part of the definition of a vector. Vectors a made of 2 or more components, depending on the dimension of the vector. A 2-D vector has two components, 3-D has three, and so on. In your case, you are probably generally working on 2-D vectors, so simply two components would be correct.

Answer:
1. Weight
2. potassium chlorate
3. pushing forward
Explanation:
1. Our full body stands in our feet, so feet takes all the weight of the body. In Newtonian mechanics, weight is a force. Weight is happened with the interaction between the mass and gravitational field. As the gravitational field is a vector, it has directions that are downward. So the interaction between mass and gravitational field works downward. So all the weight is felt by our feet.
2. In a fire stick, potassium chlorate is used. Potassium is known as a flammable chemical. Potassium chlorate is used in the upper part of the fire stick. When potassium chlorate faces frictions, a chemical reaction is happened, which creates great heat. The heat makes extra oxygen and heat, which makes the stick burn and create fire.
3. It is easy to rolling than push forward. If we consider a heavy lawn roller, the weight of the roller works downward. If we push the lawn roller, the force divided into two sub forces. One works downward which increases the weight of the roller and other works forward. But if we roll the lawn roller, the forces divided into two forces: upward and forward. Upward force makes the weight decrease and forward force makes it move forward. As the weight decrease, it becomes easy to roll than push
The distance the ball rolls is given by
<em>x</em> = 1/2 <em>a</em> <em>t</em>²
so that
<em>x</em> = 1/2 * (3.3 m/s²) * (7.5 s)² = 92.8125 m ≈ 93 m
Answer:
42cm
Explanation:
To find the volume of a box, you simply multiply the length, by the width, then by the heigh!
2cm x 7cm x 3cm = 42cm
I hope my answer helped you! :)
