Answer:
8000cm³/hr
Explanation:
Given parameters:
Volume of the liquid draining off per hour = 8000cm³
Time taken to drain off = 1hr
Unknown:
Flow rate = ?
Solution:
Flow rate is the volume of fluid that passes per unit of time.
Flow rate = [tex]\frac{volume of fluid}{time taken}[/tex]
Flow rate = [tex]\frac{8000cm^{3} }{1hr}[/tex]
Flow rate = 8000cm³/hr

A motorcycle has 100,000 J of kinetic energy and is traveling at 20 m/s. Find its mass.
Answer:
The answer is 500 kgExplanation:
The mass of the object can be found by using the formula
[tex]m = \frac{2KE}{ {v}^{2} } \\ [/tex]
v is the velocity
KE is the kinetic energy
From the question we have
[tex]m = \frac{2 \times 100000}{ {20}^{2} } = \frac{200000 }{400} = \frac{2000}{4} \\ [/tex]

a. 60 kg
b. 100 kg
c. 1000 kg
d. 6000 kg
e. 60 N
f. 100 N
g. 1000 N
h. 6000 N
i. nonsense! None of these values are even close.
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.

The coefficient of kinetic friction between a floor and a box made of wood is µk = 0.13. How far does the box slide if it has an initial speed of v0 = 7.0 m/s?
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 888990,0 kg
Explanation:
888990,0 kg is the mass of the object.
What is Gravitational force?
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.

Se lanza una pelota y regresa al punto de partida 2.5 s después ¿Que altura máxima alcanzara? ¿a que altura se hallaba 1 segundo después del lanzamiento?
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.

A machine has mechanical advantage 2,what does it mean?
Answer:
The mechanical advantage of a machine is 2. Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 2 means that for example if you apply 100 N then your machine will multiply that force and generate 200 N .

What is displacement?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.

why you are Mercury column in thermometer first decends slightly and then rises when placed in hot water?
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.

The law of conservation of matter states that matter can be neither created nor
destroyed. Your friend shows you the following chemical equation:
CaCO3+CaO+CO,
He says that because the oxygen atoms are split iretween two different molecules in
the products, the equation does not support the law of conservation of matter. Is
your friend right? Explain your answer.
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.

A train traveling at 48 m/s begins to slow down as it approaches a bend in the tracks. If it travels around the bend at a speed of 14 m/s, and it takes 40 seconds to properly slow down, what is the acceleration acting on the train during this time?
Please help 5 minutes left please!,
Answer:
Acceleration is (48-14)/40 m/s² = 34/40 m/s² = 0.85 m/s²
The acceleration acting on the train during this time of travel is 0.85m/s²
HOW TO CALCULATE ACCELERATION:
The acceleration of a moving body can be calculated by using the formula below:a = (v - u)/tWhere;
a = acceleration (m/s²)v = final velocity (m/s)u = initial velocity (m/s)t = time (s)According to this question, a = ?, v = 48m/s, u = 14m/s, t = 40s.a = (48 - 14)/40a = 34/40a = 0.85m/s²Therefore, the acceleration acting on the train during this time of travel is 0.85m/s².Learn more at: https://brainly.com/question/2040396?referrer=searchResults
