Answer:
(A⃗ ×B⃗ )⋅C⃗ = 69.868
Explanation:
We simplify the cross product first, thereafter the solution of the cross product is now simplified with the dot product as shown in the step by step calculation in the attachment
Gravity decreases with the square of the distance, so the new force is (20)/(2*2) = 5N.
Answer:
1. Dry Beans - 591.75 kg/m^3
2. Flour - 593 kg/m^3
3. Wax - 900 kg/m^3
4. Wet sand - 2039 kg/m^3
5. Chalk - 2499 kg/m^3
6. Talcum Powder - 2776 kg/m^3
7. Copper - 8960 kg/m^3
Explanation:
Make sure your units are the same
Average speed = distance traveled / time
average speed = (126.5 m * 3.5 laps) / (4.17 min)
= 106.2 m/min
A) 300cm/h
B)1 hr=60 min
300/60=5
5cm/min
C)1m=100cm
300/100=3
3m/h
