Why must there be a chain at the bottom of a truck

MrRa [10]

Answer:

Known as automatic tire chains and sometimes referred to by brand names like Onspot or Insta-Chain, these chains essentially hang listlessly from the vehicle's suspension until inclement weather arrives. When that happens, a driver can flip a switch that will lower the chains so they hang in front of the back tires.

The force of gravity acts on all apples on an apple tree. Some apples are twice as far from the ground as others. For the same m

EleoNora [17]

Answer:

c) paractically the same weight

Explanation:

The force of gravity acts on all apples on an apple tree. Some apples are twice as far from the ground as others. For the same mass these twice-as-high apples have _________.a) 1/4 weightb) 1/2 weightc) paractically the same weigh

from newton's law of motion

states that

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

f $\alpha$ =mdv/dt

dv/dt=a

f=kma

f=ma, where k is constant and equal to 1

a=g since the body is falling under gravity

acceleration of the apples become acceleration due to gravity

W=mg

since they all have equal mass, then the weight on the body will be practically and obviously the same
