Answer:
80 min
Explanation:
Distance = rate × time
280 Cal = 3.5 Cal/min × t
t = 80 min
Answer:
write the resistance of one resistor
Explanation:
This is because when resistors are connected in parallel current flows in different directions.
Displacement is a vector quantity. So, you incorporate the vector calculations when you try to determine the resultant vector. This is the shortest path from the starting point to the endpoint. If they are moving on one axis only, you use sign conventions. For motions moving to the left, use the negative sign. If it's moving to the right, then use the positive sign. Now, it the object moves 2 km to the left, and 2 km also to the right, the displacement is zero.
Displacement = 2 km - 2km = 0
Generally, the equation is:
<span>Displacement = Distance of motion to the right - Distance of motion to the left</span>
A.the composition of the inner and outer planets, current observations of star formation, and the motion of the solar system I hope this helps
Answer:
(a) 
(b) 
(c) 
Explanation:
First change the units of the velocity, using these equivalents 
and 
The angular acceleration 
the time rate of change of the angular speed 
according to:
Where 
is the original velocity, in the case the velocity before starting the deceleration, and 
is the final velocity, equal to zero because it has stopped.
b) To find the distance traveled in radians use the formula:
To change this result to inches, solve the angular displacement 
for the distance traveled 
(
is the radius).
c) The displacement is the difference between the original position and the final. But in every complete rotation of the rim, the point returns to its original position. so is needed to know how many rotations did the point in the 890.16 rad of distant traveled:
The real difference is in the 0.6667 (or 2/3) of the rotation. To find the distance between these positions imagine a triangle formed with the center of the blade (point C), the initial position (point A) and the final position (point B). The angle 
is between the two sides known. Using the theorem of the cosine we can find the missing side of the the triangle(which is also the net displacement):
