The actual size of the Solar system is too big to show without making a much smaller model. If someone wants to see the orientation of the planets a model has to be made so we can see it without flying out too space.
Answer:
sorry in my sense, an experiment once only changes one variable and need a control setup for experimental setup to make sure is fair test
The velocity of the teddy bear as it strikes the ground is 7.67 m/s.
<h3>
Velocity of the teddy when it strikes the ground</h3>
The velocity of the teddy when it strikes the ground is calculated from principle of conservation of energy as shown below.
K.E(bottom) = P.E(top)
¹/₂mv² = mgh
v² = 2gh
v = √2gh
where;
- h is height of fall of the teddy
- g is acceleration due to gravity
v = √(2 x 9.8 x 3)
v = 7.67 m/s
Thus, the velocity of the teddy bear as it strikes the ground is 7.67 m/s.

B.
This equation quantifies the inter convertibility of mass and energy and helps us understand the large amount of energy that would be released if mass were converted to energy.<span />
