Two people are pushing a couch from opposite sides. one person pushing to the right with a force of 3 N. the other person pushes

to the left a force of 4 N. which of the following best describes how the couch will move?
a) the couch will move to the left with a force of 1 N.**
b) the couch will not move.
c) the couch will move to the right with a force of 7 N.
d) the couch will move to the left with a force of 7 N.

i think its A correct me if im wrong

letter a because 4N to the left +3N to the right = 4N left minus 3N left as you change the direction of 3N then you also change the plus into minus. the direction will always favour to which of the direction is bigger

The Sun's energy reaches the earth by _____. conduction convection radiation fusion
Stels [109]
When heat or any other kind of energy move from one place
to another, conduction and convection need some material stuff
along the way, otherwise they don't happen. 

There is no material stuff between the Sun and the Earth, so
the Sun's energy reaches us by radiation.

what is the focalength of the combination of two thin renses of power -5D and -2D placeci in contact with each other?​
Ghella [55]

Answer:

f = - 0.143 m = - 14.3 cm

Explanation:

First, we will calculate the power of the combination of lenses:

P = P₁ + P₂

where,

P = Power of Combination = ?

P₁ = Power of first lens = - 5D

P₂ = Power of second lens = - 2D

Therefore,

P = - 5D - 2D

P = - 7D

Now, the focal length can be given as:

f = \frac{1}{P} \\\\f = \frac{1}{-\ 7\ D} \\\\

<u>f = - 0.143 m = - 14.3 cm</u>

Negative focal length indicates that combination will act as diverging lens.
