When you rub the balloons, it will take electrons away, which is negative. So, the balloons are negative
Answer:
Light travels fast in air but i dont know about water
Explanation:
A worker picks up the bag of gravel. We need to find the speed of the bucket after it has descended 2.30 m from rest. It is case of conservation of energy. So,
h = 2.3 m
So, the speed of the bucket after it has descended 2.30 m from rest is 6.71 m/s.
Answer:
34 m/s
Explanation:
Centripetal acceleration is:
a = v² / r
Given a = 6.55 × 9.8 m/s² = 64.2 m/s², and r = 18 m:
64.2 m/s² = v² / (18 m)
v = 34 m/s
The speed of the centrifuge is 34 m/s.
