An object weighing 4 newtons swings on the end of a string as a simple pendulum. at the bottom of the swing, the tension in the string is 6 newtons. what is the magnitude of the centripetal acceleration of the object at the bottom of the swing?
(a) 0
(b) 0.5 g
(c) g
(d) 1.5 g
(e) 2.5 g

(B) 0.5 g

Explanation:

Newton's second law says ∑  F i = m a .

the rate of change in momentum of a body is proportional to the force applied on the body.

f∝ma

f=kma

were k is constant and equal to 1

The centripetal acceleration is an acceleration.

the tension on the swing and object weight goes to the left hand side while the centripetal acceleration goes to the right handside

At the bottom of the swing, ΣF = FT – mg = mac;

notice that the tension in the swing is 1.5 times the weight of the object

we can write

1.5mg – mg = mac,

0.5mg = mac

0.5 g=ac

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.
