One way parents and guardians can influence technology use is to establish set boundaries and model proper use for their children. which of these outcomes
would you expect if this guideline was followed?
adults and children would look at things online together.
adults would spend more time reading blogs on their phones.
children would watch videos online late into the evening.
adults and children would communicate less frequently by text message.

Adults and children would look at things online together.

Explanation:

The use of technology is one of the important concern in the present day. Amidst this concern is the concern about the exposure of the children to mobiles. The use and accessibility of the mobiles depend upon the parents' decision. To establish the boundaries and to model the proper use of mobiles the adults can assist and monitor the children the ways to use the technology properly.

Δτ = 50 N.m

Explanation:

The torque applied on an object is given by the product of the force applied on it and the perpendicular distance between the force and the axis of rotation of the object. That is:

τ = F r

where,

τ = Torque applied on the object

F = Force applied on it

r = distance from axis of rotation

FOR HANDLE SIDE OF DOOR:

τ₁ = F r₁

where,

τ₁ = Torque applied on the object = ?

F = Force applied on it = 100 N

r₁ = distance from axis of rotation = 1 m

Therefore,

τ₁ = (100 N)(1 m)

τ₁ = 100 N.m

FOR MIDDLE OF DOOR:

τ₂ = F r₂

where,

τ₂ = Torque applied on the object = ?

F = Force applied on it = 100 N

r₂ = distance from axis of rotation = 1 m/2 = 0.5 m

Therefore,

τ₂ = (100 N)(0.5 m)

τ₂ = 50 N.m

Now, the difference between the amount of torque in both cases is:

Δτ = τ₁ - τ₂

Δτ = 100 N.m - 50 N.m

Δτ = 50 N.m
