Determine the horizontal component of 40m at 330 degrees?
Answer:
[tex]a_x=34.64\ m.[/tex]
Explanation:
Rectangular components of a vector
Given a vector [tex]\vec a[/tex], the x-component and y-component of the vector are given respectively by:
[tex]a_x=|\vec a|.\cos\theta[/tex]
[tex]a_y=|\vec a|.\sin\theta[/tex]
Where [tex]\theta[/tex] is the angle measured with respect to the positive horizontal direction.
Let's calculate the horizontal component of a vector with magnitude 40 m and angle 330°
[tex]a_x=40\ m.\cos330^\circ[/tex]
[tex]\boxed{a_x=34.64\ m.}[/tex]

Answer:
Mac’s Speed = 2.5 m/s
Tosh’s Speed = 4 m/s
Tosh moves 1.5 m/s faster than Mac.
Explanation:
Tosh starts from an initial position of 12m and in a span of 3 seconds, (1.00 seconds to 4.00 seconds) he moves 12 meters.
So his speed is distance / time
s = 12 / 3
s = 4 m/s
Mac starts from an initial position of 2m and in a span of 4 seconds, he traveled 10m (2.00m to 12.00m).
Speed = Distance / time
s = 10 / 4
s = 2.5 m/s

Add the m/s sign to the 125. 125 m/s.
Answer = 125 m/s. Hope this helps!
The two objects have different masses, the more massive object pulls with a greater force. TRUE OR FALSE?
Answer:
on earth yes, but in space no because there is no gravity
Explanation:
plz can i have some points
The force exerted by an object depends on the mass of the object. Greater mass results in greater force. Hence, the statement is true.
What is force?Force is an external agent acts on a body to change the substance from the state of rest or motion. There are various kinds of force such as nuclear force, magnetic force, frictional force etc.
According to Newton's law of motion force in a moving body is the product of its mass and acceleration. Hence, force is directly proportional to mass and acceleration and an increase in these quantities will increase the force exerted by the body.
Thus, greater force is needed to a move a body with greater mass. If two objects of different masses exerts force each other, the greater force will be exerted by the massive body.

Light takes 1.28 s to travel from the Moon to Earth. What is the distance between them?
Answer:
384,000
Explanation:
Time taken by light to travel from earth to moon t=1.28s
Let us assume that the speed of light = c
So, the distance traveled by light in this time = c x t
this will be the distance which light traveled to reach moon, so this will be the distance between earth and moon.
The speed of light is 300000 km/s
By putting the values
we get
Distance = c x t
= 300000 x 1.28 km
=384000 km
Goal: Use dimensional analysis to solve conversion problems. 1. Observe: In the question, you are asked to convert kilometers to centimeters. To do this, first you will convert kilometers to meters. Drag the 1000 meters/1 kilometer tile down. A. What do you notice? __________________________________________________ B. Because kilometers appear in the numerator of one term and in the denominator of another, they cancel, or disappear. The process of converting units by canceling is called dimensional analysis. How many meters are in 0.828 kilometers? ________________________________ C. A meter is a much shorter unit of measurement than a kilometer. Based on this fact, does your answer to B make sense? ______________________________________
Answer:
A. The kilometers unit is cancelled out and the result shown is 828 meters.
B. 828 meters are found in 0.828 Kilometers
C. Yes
Explanation:
A. When the 1000 meters/1 kilometer tile is dragged down, the kilometers unit is cancelled out and the value 828 meters appears.
This is because the kilometers appear in the numerator of one term and in the denominator of another, they cancel, or disappear. The process of converting units by canceling is called dimensional analysis.
B. 0.828 Kilometers * 1000 meters/1 kilometer = 828 meters
Therefore, there are 828 meters in 0.828 kilometers.
C. A meter is a much shorter unit of measurement than a kilometer. Based on this fact, it does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.
(A) The process of converting units by canceling is called dimensional analysis.
(B) There are 828 meters in 0.828 kilometers.
(C) It does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.
The given problem is based on some basic fundamentals and applications of dimensional analysis. So as per the given problem, each subpart says,
A.
When the 1000 meters/1 kilometer tile is dragged down, the kilometers unit is cancelled out and the value 828 meters appears.
This is because the kilometers appear in the numerator of one term and in the denominator of another, they cancel, or disappear. The process of converting units by canceling is called dimensional analysis.
Thus, we can conclude that the process of converting units by canceling is called dimensional analysis.
B.
Converting the given value of kilometers into the meters as,
0.828 Kilometers * 1000 meters/1 kilometer = 828 meters
Thus, we can conclude that there are 828 meters in 0.828 kilometers.
C.
A meter is a much shorter unit of measurement than a kilometer. Based on this fact, it does make sense that 0.828 Kilometers which is less than 1 kilometer is equal to 828 meters.

1. A car is traveling at 36 m/s hits a tree and comes to rest in 0.05 seconds.
a. What is the acceleration of the car?
b. Airbags deploy in a car if the acceleration of a car exceeds -600 m/s^2 Will the airbags deploy?
Answer: a. -720m/s^2
b. Yes, airbags will deploy
Explanation:
The formula for acceleration is:
= (Final velocity - Initial velocity)/Time
Final velocity = 0m/s
Initial velocity = 36m/s
Time taken = 0.05s
= (Final velocity - Initial velocity)/Time
= (0 - 36)/0.05
= -36/0.05
= -720m/s^2.
Since it's negative, it shows that there was a deceleration.
2. Yes the airbag will deploy since the acceleration gotten is more than -600 m/s^2.

Consider this situation: A force is applied to a box to move it
to the right across the kitchen floor. Of the forces listed,
identify which act upon the box.
Answer:
The static "frictional force" and the "kinetic friction" will act on the box.
When A force is applied to a box to move it to the right across the kitchen floor, static friction force comes into play before start moving. When the box starts moving, dynamic friction force comes into play.
What is friction?
The resistance provided by surfaces in touch as they move past one another is known as friction.
To walk without slipping, traction is provided by friction. In most situations, friction is advantageous. They do, however, give a strong amount of opposition to the move.
When A force is applied to a box to move it to the right across the kitchen floor, static friction force comes into play until it starts moving. When the box starts moving, dynamic friction force comes into play.

A sample of gold has a mass of 96.5g and a volume of 5.00cm^3. What is the density of gold?
Explanation:
sample of gold has a mass of 96.5 g and a volume of 5.00 cm3. The density of gold is a. 0518 g/cm3.
Taking into account the definition of density, the density of gold is 19.3 [tex]\frac{g}{cm^{3} }[/tex]
But first you must know the definition of density. Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is the relationship between the weight (mass) of a substance and the volume that the same substance occupies.
The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
In this case, you know that:
mass= 96.5 gvolume= 5 cm³Replacing in the definition of density:
[tex]density=\frac{96.5 g}{5 cm^{3} }[/tex]
Solving:
density= 19.3 [tex]\frac{g}{cm^{3} }[/tex]
In summary, the density of gold is 19.3 [tex]\frac{g}{cm^{3} }[/tex]
