A :-) 1.) 3rd law of motion.
2.) 2nd law of motion ( law of inertia ).
- 2nd law states that if an object has more mass then it has more inertia ( mass = inertia ).
So , here the empty shopping cart is easier to push compared to loaded one.
3.) 1st law of motion.
- 1st law states that a object in rest will stay at rest , if a object is in motion it will stay at motion until a unbalanced force is applied on it.
So , here the baseball was in motion then , an unbalanced force ( bat ) was applied on it , so the was thrown up into the air.
4.) 3rd law of motion.
- 3rd law states that every action force has an equal and opposite reaction force.
So , here when your walking , your foot pushes the ground backwards ( action force ) , and the ground pushes your foot forward ( reaction force ).
5.) 1st law of motion.
The best answer to fill in the blank should be ''continuation'' because series means a lot and lines are long, narrow, figures, so its continuation since its constant.

The answer is - both magnetic poles</span>
<span>In the earth's southern magnetic pole, auroras are known as aurora austalis or southern lights while in the northern magnetic pole they are known as aurora borealis or northern lights.</span>
<span>They are caused by charged particles borne in solar winds that are escaping from the sun. As they approach the earth, the winds distort the earth's magnetic field which allows some particles to enter the earth's atmosphere, where they excite the gases and make them glow with spectacular display of colors.</span>

The acceleration of the wooden box is 6.17 m/s² towards the west.
<h3 /><h3>What is acceleration?</h3>
Acceleration can be defined as the rate of change of velocity.
To calculate the acceleration of the wooden box can be calculated using the formula below.
Formula:
- F₂-F₁ = ma.................. Equation 1
Where:
- F₂ = Force on the wooden box acting towards west
- F₁ = Force on the wooden box acting towards the east
- m = Mass of the wooden box.
- a = Acceleration of the wooden box
Make a the subject of the equation
- a = (F₂-F₁)/m........................ Equation 2
From the question,
Given:
- F₂ = 270.7 N
- F₁ = 85.7 N
- m = 30 kg
Substitute these values into equation 2
- a = (270.7-85.7)/30
- a = 185/30
- a = 6.17 m/s² towards the west.
Hence, The acceleration of the wooden box is 6.17 m/s² towards the west.

Answer:
Part of the question is missing but here is the equation for the function;
Consider the equation v = (1/3)zxt2. The dimensions of the variables v, x, and t are [L/T], [L], and [T] respectively.
Answer = The dimension for z = 1/T3 i.e 1/ T - raised to power 3
Explanation:
What is applied is the principle of dimensional homogenuity
From the equation V = (1/3)zxt2.
- V has a dimension of [L/T]
- t has a dimension of [T]
- from the equation, make z the subject of the relation
- z = v/xt2 where 1/3 is treated as a constant
- Substituting into the equation for z
- z = L/T / L x T2
- the dimension for z = 1/T3 i.e 1/ T - raised to power 3
