Answer:

7) Example: Gravitational force

Gravitational force, also known as gravity, is a type of non- contact force.

10) Unbalanced forces can cause an object to accelerate, make a stationary object move, or cause a moving object to stop.

12) Gravitational force, Frictional force, Magnetic force

13) Friction is beneficial when we are walking as it prevents us from slipping.

For the table, find the net force first and that would help us to find the direction and the type of force (balanced/ unbalanced).

As written in Q11, add all the forces together to determine the net force acting on an object. More specifically, add the forces that act in one direction together. Then subtract the forces acting in the other direction.

Let's look at the teddy bear (Q14 -16):

Take note that we have to look at the direction of the arrow not which side the arrow is on (left/ right of the bear).

Total force acting towards the left

= 16 +7

= 23N

Total force acting on the right= 22N

Net force

= 23 -22

= 1N towards the left

Thus, 14) Unbalanced (since the net force is not 0N)

15) 1N

15) 1N16) left

Vase question:

Total downward force

= 11 +33

= 44N

Total upward force

= 25 +19

= 44N

Net force= 0N

17) Balanced

17) Balanced18) 0N

17) Balanced18) 0N19) No direction

Bicycle question:

Total force acting towards the right

= 65 +115

= 180N

Total force to the left= 170N

Net force

= 180 -170

= 10N to the right

20) Unbalanced

20) Unbalanced21) 10N

20) Unbalanced21) 10N22) To the right

When sodium hydroxide NaOH dissociates in water, the oxygen atoms on the hydroxide anions will interact with:

Inessa05 [86]

Answer:

Hydroxide ions ( OH−) are negatively charged, and the formal negative charge is on the oxygen atom. Since opposite charges attract, the oxygen atoms will interact with the positive end of water's dipole.

A mixture of CO2 and Kr weighs 35.0 g and exerts a pressure of 0.708 atm in its container. Since Kr is expensive, you wish to re

ollegr [7]

Explanation:

Since, it is given that carbon dioxide is completely removed by absorption with NaOH. And, pressure inside the container is 0.250 atm.

For Kr = 0.250 atm and pressure $CO_{2}$ will be calculated as follows.
