1) C. velocity
Acceleration is defined as the rate of change of velocity per unit time. In formulas:
where
is the change in velocity
is the time interval
Therefore, the correct answer is C. velocity.
2) A. 9.8m/s/s
Earth's gravity is a force, so it produces an acceleration on every object with mass located on the Earth's surface. This acceleration can be calculated, as it is given by the formula
where
is the gravitational constant
is the Earth's mass
is the Earth's radius
By substituting these numbers into the formula, one can find that the acceleration due to Earth's gravity is 
.
Answer: 1. the object is moving away from the origin
4. the object started at 2 meters
5. the object is traveling at a constant velocity

The Thermal radiation is one of "3 mechanisms who allows to bodies exchange energy".
The thermal radiation formula is given by:
Where 
If we solve for P we got:
Since we have a baseball ball considered as a sphere the superficial area is given by:
Solution to the problem
And if we replace this into our equation of P we got:
And we can reorder this like that:
We can convert the radius to meters and we got:
Now we can convert the temperature to Kelvin and we got:
the emissivity given
And now we can replace into the formula for P and we got:
Answer:
Hey, I'm not sure I understand exactly what your assignment is but hopefully this helps . . .
put the other end against the side of the bubls base to light up the light bulb.
This will act as the bulbs conductor, lighting up bc you are making a complete electrical circuit between positive and negative terminals of the battery.
Ok hopefully this helps you out
