Answer: Wouldn't it just be her blocks all walked in an hour added together?
Explanation: 5+2+3+2=12 so 12 blocks an hour?
Answer:
20watts
Explanation:
Formula for calculating power is expressed as;
Power = Work done/Time
Note that the unit of workdone is Joules
Unit of Time is seconds
Hence the unit of power is Joules/seconds or J/s
Hence if the rate at which energy is used up is 20.0J/s, the power will also be 20J/s or 20watts since they have the same unit.
Reference point is the answere
Answer: The acceleration that is directed radially towards the center of the circle having a magnitude equal to the square of the speed of the body along the curve is divided by the total distance from the center of the circle to the moving body.
Explanation:
Yw and mark me brainiest
Answer:
the answer is at
Explanation:
Dimension of at = [ LT^-2 ] [ T ]
= [ LT^(-2+1) ]
= [ LT^-1 ]
which is same as dimension of speed.
