Answer:
2.5 x 10⁷ J
Explanation:
F = thrust of the engine = 2.3 x 10⁵ N
d = distance traveled = 87 m
Work done by the engine is given as
W = F d = (2.3 x 10⁵) (87) = 200.1 x 10⁵ J
W' = Net work done
W'' = work done by catapult
KE₀ = initial kinetic energy = 0 J
KE = final kinetic energy = 4.5 x 10⁷ J
Net work done is given as
W' = KE - KE₀
W' = 4.5 x 10⁷ J
We know that
W' = W + W''
4.5 x 10⁷ = 2.001 x 10⁷ + W''
W'' = 2.5 x 10⁷ J
Answer:
The graphic organizers help to keep track of the details. They are a visual representation of knowledge that rescue the important aspects of a concept using labels within a scheme. They also present information in a concise manner, highlighting the organization and the relationship of the concepts. Graphic organizers help students organize their thinking process and their writing.
Explanation:
If you look at a atom under a electron microscope you would use it
Answer:
Momentum
Explanation:
Truck A has a greater momentum compared to Truck B.
Momentum is the product of mass and velocity of a body;
Momentum = mass x velocity
We see that the body with more mass and velocity will have a higher momentum.
Since the two bodies have the same mass, and the speed A is greater, then A will have a greater momentum.
Given what we know, we can confirm that investigative questions are used to develop and test hypotheses and often lead to the formation of an experiment.
<h3>What are investigative questions?</h3>
These are questions posed by scientists that will often lead to a hypothesis. They are the crucial first step in the scientific process. Some examples of investigative questions include:
- Why are plants green?
- Does gravity affect all objects equally?
- What makes ice melt?
etc.
Therefore, we can confirm that investigative questions such as these are often the basis on which hypotheses are created and experiments are made in order to test the speculated results.
