Its a bit confusing. Please answer.​

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.

Answer:

the switch or the wire

Explanation:

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:

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

Answer: 1 = Heat

Answer:

12m/s2

Explanation:

:D (just a smiley, not answer d)

Answer:

-47.04

Explanation:

Divide 12 m by 2.5 m/s which equals 4.8s

And then use 4.8s to multiply it with -9.8

4.8(-9.8)= -47.04 m/s

Hope this helped!! :)

The initial height of the pumpkin is 23.52m and the final vertical velocity of the pumpkin is 47.04 m/s.

Initial horizontal speed, u = 2.5 m/s

horizontal distance covered , d = 12m

So the time taken is:

t = d/u

t = 12/2.5 s

t = 4.8s

Now, the initial vertical speed, v = 0

So the vertical distance traveled by the pumpkin will be equal to the initial height of the pumpkin:

s = vt + ¹/₂gt²

s = 0.5 × 9.8 × 4.8 m

s = 23.52m

Final vertical velocity:

v' = v + gt

v' = 9.8 × 4.8 m/s

v' = 47.04 m/s

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options. However, one material that is good candidate for conducting electricity without reacting with other materials is metallic vanadium dioxide. This is because of the inability of this electrical conductor to conduct heat (an unusual property for all other electrical conductors) and thus makes it difficult for it to react with other materials (since an increase in temperature increases possibility of a reaction).

Answer:

b

Explanation:

Answer:

a) 60kg

Explanation:

mass is not affected by gravity

The mass of Joe on the moon is approximately 60 kg. Hence, option (a) is correct.

Given data:

The weight of Joe is, W = 600 N.

The weight of any object is the product of mass and gravitational acceleration of an object. It is the expressed as,

W = mg

Here,

m is the mass of Joe.

g is the gravitational acceleration.

Solving as,

W = mg

600 = m × 10

m = 60 kg.

Thus, we can conclude that the mass of Joe on the moon is approximately 60 kg. Hence, option (a) is correct.

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.

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.

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.
