The answer is A
Explanation:
Vacuuming doesn’t involve a lot of physical movements.
Answer
m/s rate of change of dispalcement per sec. ie velocity
m/s^2 is (m/s)/s ie rate of change of velocity per sec. ie accelerationplanation:
Answer:
The correct solution is "14.6875 kg".
Explanation:
Given values:
Force,
F = 47.0 N
Acceleration,
a = 3.20 m/s²
Now,
⇒ 
or,
⇒ 
⇒ 
⇒ 
⇒ 
So E = 2x10^-3W/m^2*(π*(3.0x10^-3m)^2)*1min*60s... = 3.4x10^-6J
