6.35x10^-4 OR 6.3x10-4 (if only one decimal number is allowed)
Answer:
v (speed) = S / t = 4 * 400 m / (6 * 60 sec) = 4.4 m/s
The average velocity is zero because there is no net vector displacement.
Answer:
if the radius of the artery decreases by a factor of 1.5 because of the blockage by what factor has the volume flow rate decreased?
(1) acceleration, a = 4 m/ (2) acceleration of 10 N, = 1 m/ and acceleration of 30 N, = 3 m/
Explanation:
- Here, the acceleration of the object could be found using the equation derived in the second law of motion. The equation is given as, F = ma where m is the acceleration of the object, m is the mass of the object and F is the applied on the object.
- Let be the acceleration for force 10 N, to find acceleration rearrange the equation to a = . When we substitute 10 N force and 10 kg mass of the box in the equation. We will get = 1 m/
- Let be the acceleration for force 30 N, to find acceleration rearrange the equation to F = . When we substitute 30 N force and 10 kg mass of the box in the equation. We will get = 3 m/
- To find the combined, just add the force and substitute in the above equation. Hence, a = 4 m/
