What do we mean when we describe forces as balanced?

Well, first, let's recognize that there is no such thing as a force that is
balanced or unbalanced.

When we say that a group of two or more forces is balanced, we mean
that when you add up all the magnitudes and directions of the forces, the
whole group adds up to zero, so they have the same net effect as if there
were no force at all.

How much work is done if 10 N is applied to a 5kg object for 10 meters if there is an opposing force of 5 N
BlackZzzverrR [31]

Answer:

50 J

Explanation:

The net force acting on the box is given by the algebraic sum of the two forces, so:

F=10 N -5 N = 5 N

The net work done on the box is equal to (assuming the net force is parallel to the displacement of the object)

W=Fd

where

F = 5 N is the net force on the object

d = 10 m is the displacement of the object

Substituting,

W=(5 N)(10 m)=50 J

Nuclear winter story. A crazy president is trying to solve the global warming problem and has successfully built a powerful H-bo
Irina18 [472]

Answer:

A nuclear winter is a climatic phenomenon that would follow the detonation of several atomic bombs in the event that a nuclear war broke out. These bombs would cause firestorms that would raise smoke, dust and particles into the atmosphere that would end up in the stratosphere and eventually spread throughout the globe.

Explanation:

That idea is far fetched, because even though those same particles would absorb sunlight, it would raise the temperature in the stratosphere and cause a decrease in temperature in the Earth's layer. Unable to seep the sun's rays, many plant species would die and this would affect the entire food chain.

In addition, that temperature rise in the stratosphere would destroy part of the ozone layer, causing greater exposure to ultraviolet rays. This would end up affecting health and further damaging plant species.

Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.60×106 N, one at an angle 13.0 west of north, an
Juliette [100K]

Answer:W=1.93\times 10^9 J      

Explanation:

Given

Force F=1.6\times 10^{6} N

one at an angle of 13^{\circ} East of North and another at 13^{\circ} West of North

Net Force is in North Direction

F_{net}=2F\cos 13

Forces in horizontal direction will cancel out each other

thus Work done will be by north direction forces  

W=2F\cdot \cos 30\cdot s

here s=0.7 km

W=2\times 1.6\times 10^{6}\cdot \cos 30\cdot 700

W=1.93\times 10^9 J
