My commute to school is a constant distance, but the time it takes to get there fluctuates owing to traffic.

If an object moves with respect to a reference frame, such as when a passenger travels to the back of an airliner or a professor moves to the right with respect to a whiteboard, the item's position changes.

This change in location is described as displacement.

My commute to school is a constant distance, but the time it takes to get there fluctuates owing to traffic,

The initial and the final position of the commute is the same, but the displacement varies with the route which affects my car's speed and where it is in line at stop lights.

Explanation:

f=175N

m=43kg

a=?

know

f=ma

a=f/m

a=175/43

a=4.06m/s

If a net horizontal force of 175 N is applied to a bike whose mass is 43 kg, acceleration is produced 4.06 m/s².

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Given in the question,

f = 175 N

m = 43 kg

a =?

know

f = ma

a = f/m

a = 175/43

a = 4.06 m/s²

If a net horizontal force of 175 N is applied to a bike whose mass is 43 kg, acceleration is produced 4.06 m/s².

Answer:

no

Explanation:

the metal spoon would be higher temperature

Answer:

Yes

Explanation:

The equation you wrote is incorrect,

the correct is: CaCO3+CaO+CO2

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed. Therefore, the quantity of mass is conserved over time.

Your friend is incorrect in saying that this doesn't follow the law of conservation of mass. The molecule of oxygen is split up but the number of total atoms of oxygen is same. So, it follows the law of conservation of mass.

Answer:

it is push or pull and it is machanical energy but the arrows are going out so it means it is pull

the reason is because it the arrows are going out that means they are using mecanichal energy bc they using hands the evedance is that we can identify the energy

Explanation: its common sense

Answer:

a) [tex] y_{max} = 7.7 m [/tex]

b) y = 7.4 m

Explanation:

a) La altura máxima que alcanza la pelota se puede encontrar usando la siguiente ecuación:

[tex] y_{max} = y_{0} + v_{0y}t - \frac{1}{2}gt^{2} [/tex]    (1)

En donde:  

[tex]y_{0}[/tex]: es la altura inicial = 0

[tex]v_{0y}[/tex]: es la velocidad inicial en y

g: es la gravedad = 9.81 m/s²

t: es el tiempo

Primero debemos encontrar la velocidad inicial en y:

[tex] v_{fy} = v_{0y} - gt [/tex]

Sabiendo que la velocidad final en y es igual a cero (en la altura máxima), y con t = 1.25 s (la mitad del tiempo total) tenemos:

[tex] v_{0y} = gt = 9.81 m/s^{2}*1.25 s = 12.3 m/s [/tex]

Ahora, podemos encontrar la altura máxima:

[tex] y_{max} = v_{0y}t - \frac{1}{2}gt^{2} = 12.3 m/s*1.25 s - \frac{1}{2}9.81 m/s^{2}*(1.25 s)^{2} = 7.7 m [/tex]

b) Podemos encontrar la altura cuando t = 1 s con la misma ecuación (1):

[tex]y_{max} = y_{0} + v_{0y}t - \frac{1}{2}gt^{2} = 12.3 m/s*1 s - \frac{1}{2}9.81 m/s^{2}*(1 s)^{2} = 7.4 m[/tex]

Por lo tanto, la pelota se encontraba a 7.4 m luego de 1 segundo despúes del lanzamiento.

Answer  888990,0 kg

Explanation:

888990,0 kg is the mass of the object.

Any two mass-containing objects are attracted to one another by the gravitational force. Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive.

Newton's Universal Law of Gravitation is what it is known as.

Admittedly, you aren't pushing on those other objects all that much because you don't have a very large mass. Additionally, items that are very far apart from one another do not clearly tug on one another. 

Therefore, 888990,0 kg is the mass of the object.

Answer:

obviously sasuke

Explanation:

everyone is always over estimating borutos powers like lets be real here sasuke is almost as strong as naruto and when they were younger he had better hand to hand combat and in jutsu's he was a prodigy and he is able to calculate precise movements to try and defeat his oponent lets not forget that he has the sharingon over whatever jutsus boruto has (i dont know because ive never seen the anime and i dont plan on doing so) (i hate boruto its trash) which means he could read borutos chakra and he would be more powerful because his sharingan awoken when he was a mear child he would be much more powerful beause hes mastered his sharingan. oh yeah and his fire ball and chidori (which could k!11 boruto if sasuke inflicts enough chakra into his jutsu) (if u want to say otherwise my pronouns are she/her so use them if u want to say something involving pronouns thanks)

Answer:

s = 19.23 m

Explanation:

Since, the frictional force is given as:

f = μN = μW

f = μmg   ----------- equation (1)

but, from Newton's 2nd Law:

f = ma   -------------- equation (2)

comparing equation (1) and equation (2):

ma = μmg

a = μg

here,

a = acceleration of puck

μ = coefficient of static friction = 0.13

g = -9.8 m/s² (negative sign for slowing down of puck)

Therefore,

a = (0.13)(-9.8 m/s²)

a = -1.274 m/s²

Now, using 3rd equation of motion:

2as = Vf² - Vi²

where,

s = distance covered = ?

Vf = Final Velocity = 0 m/s (since, puck finally stops)

Vi = Initial Velocity = 7 m/s

Therefore,

2(- 1.274 m/s²)s = (0 m/s)² - (7 m/s)²

s = (- 49 m²/s²)/(- 2.548 m/s²)

s = 19.23 m

Explanation:

Because When placed on hot water, the thermometer itself expands slightly first so the Mercury appears to be descending. After the thermometer expands slightly, the Mercury expands. Hence, Mercury column in thermometer first decends slightly and then rises when placed in hot water

Answer:

Any liquid in a container, when heated, at first it's level goes down a little, then rises.

It's because the container volume increases first, before the liquid gets hot. So the level goes down. It takes a little longer to heat up the whole volume of the liquid. A little later, as the liquid gets heated up, it expands faster than the container and the level rises.

In general, coefficient of thermal expansion is higher for liquids than solids.

This is why the mercury level first goes down then rises.
