Answer:
The center of mass changes
Explanation:
The higher the center of mass the more likely things are to topple over but the lower it is the more likely to stay put when all 4 wheels are down .
Answer:
Part A:
(a): -121.26 ft/s.
(b): -121.13 ft/s.
(c): -121.052 ft/s.
(d): -121.026 ft/s.
Part B:
-121.00 ft/s.
Explanation:
Given that the height of the balloon after t seconds is
The average velocity of an object is defined as the total distance traveled by the object divided by the time taken in covering that distance.
where,
are the positions of the object at time and respectively.
<h2><u>
Part A:</u></h2><h2 />
- For the average velocity for the time period beginning when t=3 and lasting .01 sec.
For this case,
- For the average velocity for the time period beginning when t=3 and lasting .005 sec.
For this case,
- For the average velocity for the time period beginning when t=3 and lasting .002 sec.
For this case,
- For the average velocity for the time period beginning when t=3 and lasting .001 sec.
For this case,
<h2><u>
Part B:</u></h2>
The instantaneous velocity of the balloon at the given time is defined as the rate of change of its position at that time.
<u>Note:</u><em> The negative sign with all the velocities indicates that the direction of these velocities are downwards.</em>

Because, say the diamond was 125 feet on both right and left fields, the center field would be 130 feet long, see what i mean? I hope I helped. :)
Answer:
0.1 A
Explanation:
From the question,
V = IR............ Equation 1
Where V = Voltage, I = current, R = Resistance.
Given: I = 0.2 A, R = 10 ohms.
Substitute into equation 1
V = 0.2(10)
V = 2 volt,
If the resistor is replaced with a 20 resistor, The nwe current is
I = V/R................ Equation 2
I = 2/20
I = 0.1 A
