What is the netforce?
Answer:
6 Newtons to the left.
Explanation:
We can convert this into a generic algebra equation by giving directions positive and negative values.
The 6 will be positive, and the 10 and 2 will be negative.
Add 10 and 2 to have 12.
6-12 = -6.
Therefore you have 6 newtons to the left (negative).

From base camp, a park ranger drives 27 meters at 32 degrees East of North, then 40 meters at 58 degrees West of North, and finally 39 meters directly West in an attempt to rescue a lost hiker.
Answer:
R = 73.34 m, θ = 37º North of West
Explanation:
In this exercise you are asked to find the distance traveled.
The best way to do this is with a Cartesian coordinate system, let's use a system where the x axis coincides with the West - East direction), to decompose the trajectories
First trajectory
distance d₁ = 27 m
Direction 32 East of North, this angle is measured from the vertical direction (y-axis)
cos 32 = y₁ / d₁
sin 32 = x₁ / d₁
y₁ = d₁ cos 32
x₁ = d₁ sin 32
y₁ = 27 cos 32 = 22.90 m
x₁ = 27 sin 32 = 14.31 m
second trajectories
distance d2 = 40 m
direction 58 West from North, the angle is measured with respect to the y axis, towards the negative side of the x axis
cos 58 = y₂ / d₂
sin 32 = x₂ / d₂
y₂ = d₂ cos58
x₂ = d₂ sin 58
y₂ = 40 cos 58 = 21.20 m
x₂ = 40 sin 58 = -33.92 m
The negative sign of the x coordinate is due to the fact that the displacement is towards the West (negative of the x axis)
third trajectory
distance d₃ = 39 m
West direction, negative part of x-axis
x₃ = - 39 m
the total distance is
= x₁ + x₂ + x₃
X_{total}l = 14.30 - 33.92 -39
X_{total}X_total = -58.6 m
Y_{total} = y₁ + y₂
Y_{total}= 22.90 + 21.20
Y_{total} = 44.1 m
we give the result in the form of module and angle
we use the Pythagorean theorem
R = [tex]\sqrt{X_{total}^2 + Y_{total}^2 }[/tex]
R =\sqrt58.6^2 + 44.1^2 }
R = 73.34 m
we use trigonometry
tan θ =
θ = tan⁻¹ \frac{ Y_{total} }{ X_{total} }
θ = tan⁻¹ \frac{ 44.1 }{ 58.6 } (44.1 / 58.6)
θ = -37º
this angle is in the second quadrant, given in the form of cardinal coordinates is
θ = 37º North of West
Dominique and her sister are practicing their basketball skills at the park. If both Dominique and her sister both throw their basketballs at the same time and they hit each other. What would happen to their basketballs? a) Only the basketball's speed would be changed b) Only the basketball's directions would be changed c) Both the basketball's speed and direction would change d) Neither the basketball's speed nor direction would change
Answer:
Option C, Both the basketball's speed and direction would change
Explanation:
When two objects travelling with certain speed interact with each their internal forces changes and hence their motion changes simultaneously.
In general cases it is said that momentum is conserved. Momentum is nothing but just the product of mass and velocity.
As the motion of the football changes, then momentum also changes. Since mass is a constant value, it is the velocity of the football that changes.
Hence, both speed and direction of both the football changes.
Option C is correct

Explain why the following statement is either true or false: The idea that all matter consists of the elements was first introduced a few hundred years ago
It is a true statement that the idea that all matter consists of elements was first introduced a few hundred years ago.
What is the matter?Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
Individuals have believed that earth, air, water, and fire are the only four elements that make up matter for roughly two thousand years.
For more than two thousand years, Aristotle's theory that all matter is composed of just four elements was accepted, but only around 500 years ago did scientists begin to find all of the elements that are currently recognized.
Beginning around five hundred years ago, scientists started learning about all of the elements that are currently recognized.

A negative charge of -2 C and a positive charge of 5 C are separated by 84,752 m. What is the force between the two charges?
Answer:
F = 12.52 N
Explanation:
Given that,
Charge, q₁ = -2 C
Charge, q₂ = 5 C
The distance between charges, d = 84,752 m
We need to find the force between the two charges. The force between two charges is given by :
[tex]F=k\dfrac{q_1q_2}{d^2}\\\\F=9\times 10^9\times \dfrac{2\times 5}{(84752)^2}\\F=12.52\ N[/tex]
So, the force between charges is 12.52 N.
Laura puts her file cabinet on a small cart with wheels which will occur. A Laura will increase the amount of friction. B Laura will reduce the force she needs C Laura will decrease the amount of motion D Laura will increases the force she needs
Answer: b
Explanation:
Laura will increase the force she needs. When Laura puts her file cabinet on a small cart with wheels, the cart will experience less friction compared to the file cabinet directly resting on the ground. The correct answer is option D.
The presence of wheels reduces the contact area between the cart and the ground, leading to lower frictional forces. As a result, it becomes easier for the cart to move. However, the file cabinet still possesses its original mass, so to accelerate the cart (and the cabinet) to a certain speed or maintain a constant velocity, Laura will need to exert a greater force on the cart due to the reduction in friction. Therefore, the correct answer is D - Laura will increase the force she needs.
