Answer: Limiting reactant
Explanation:
The limiting reactant is a reactant will get completely consumed up in the reaction. This reactant being in low concentration will lead to the formation of limited amount of product.
In the given situation, since the butter cakes are required to be 3 sticks for making 3 cakes but only 2 cakes are available thus the butter stick is the limiting reactant.

En la etiqueta de un bote de fabada de 350 g, leemos que su aporte energético es de 1630 kj por cada 100 g de producto a) La cantidad de fabada que tiene que comer un hombre si su necesidad energética diaria es 2500 kj para sobrevivir b) El aporte calórico del bote de fabada en calorías
Answer:
(a) 153.37 g
(b) 5705 kJ
Explanation:
(a) To find the amount of bean needed by a man you first calculate the equivalence in beans to 2500kJ
[tex]2500kJ*\frac{100g}{1630kJ}=153.37\ g[/tex]
Thus, 153.37 g has the energy needed by a man that needs 200kJ per day.
(b) The amount of energy per pot of bean is given by:
[tex]E=350g*\frac{1630kJ}{100g}\\\\E=5705\ kJ[/tex]
Thus, the energy is 5705kJ

An ice skater spins at 2.5 rev/s when his arms are extended. He draws his arms in and spins at 10.0 rev/s. By what factor does his moment of inertia change in the process?
Answer:
The moment of inertia decreased by a factor of 4
Explanation:
Given;
initial angular velocity of the ice skater, ω₁ = 2.5 rev/s
final angular velocity of the ice skater, ω₂ = 10.0 rev/s
During this process we assume that angular momentum is conserved;
I₁ω₁ = I₂ω₂
Where;
I₁ is the initial moment of inertia
I₂ is the final moment of inertia
[tex]I_2 = \frac{I_1 \omega_1}{\omega_2} = \frac{I_1*2.5}{10} \\\\I_2 = 0.25I_1 = \frac{1}{4}I_1[/tex]
Therefore, the moment of inertia decreased by a factor of 4
When using the lens equation, a negative value as the solution for d baseline i indicates that the image is
A. real
B. virtual
C. upright
D. inverted
When using the lens equation, a negative value as the solution for d baseline i indicates that the image is Virtual. The correct option is B.
What is reflection?When a light strikes on a shiny surface, it reflects back the light ray in the same medium. The phenomenon is called reflection and the ray is called the reflected ray.
From the Len's maker formula, e have
1/f = 1/u + 1/v
where f = radius of curvature /2
So, the negative value as the solution for d baseline i indicates that the image is Virtual.
Thus, the correct option is B.

Gold, quartz, and talc are minerals. Copper and iron are types of ore. What is the difference between minerals and ores?
A mineral is a non-living, solid substance that can be extracted from the ground. Ore is a type of mineral made up of metals.
An ore is non-living and solid with little value unless it occurs in large amounts, in which case it is a mineral.
O A mineral is a valuable form of ore that can be extracted from the ground
O A mineral is a non-living, solid substance made of elements. Ore is a large deposit of one or more valuable minerals in the ground.
Answer:
A mineral is a valuable form of ore that can be extracted from the ground
Explanation:
Gold, quartz and talc are minerals because they are found in the earth in a valuable form of ore while ores are rocks that contain valuable concentrations of minerals.that can be mined.
An ORE in general term can be said to be a mineral deposit that contains enough Minerals that can be mined in commercial quantities while Minerals are valuable components of an Ore that can be mined ( naturally occurring ) in an ORE.

Object A has a mass of 10 kg and is moving at a velocity of 2.0
m/s. So Object A's momentum is - kg. m/s.
Answer:20kgm/s
Explanation:
Mass=10kg
Velocity=2m/s
Momentum=mass x velocity
Momentum=10 x 2
Momentum=20
Momentum=20kgm/s
The object with mass m when moving with the velocity, its momentum can be calculated. The momentum of the object A is 20 kg.m/s.
What is momentum?Momentum is the product of mass and velocity of a moving object.
If the momentum is p, the mass of the object is 10 kg and the velocity is 2.0 m/s, then the momentum will be
p = 10 × 2.0
p = 20 kg.m/s
Thus, the momentum of the object A is 20 kg.m/s

Rafael swings a baseball bat with a force of 25 N. The baseball bat exerts a force of 5 N on the baseball. What is the mechanical advantage of the baseball bat? The mechanical advantage of the baseball bat is
Answer:
0.2
Explanation:
Mechanical Advantage is defined as the ratio of force output with respect to the force input. Thus,
MA = output / input
MA = 5 / 25
MA = 1/5
MA = 0.2
Since this value is less then one. Even though it's tagged a mechanical advantage, in reality it would be mechanical disadvantage.
Therefore, we can say that the mechanical advantage of the baseball bat is 0.2

A boat at anchor is rocked by waves whose crests are 28 m apart and whose speed is 7 m/s. How often do these waves reach the boat? State your answer in terms of frequency (Hz) and period T (seconds).
Answer:
0.25 Hz
4 s
Explanation:
Speed = wavelength × frequency
7 m/s = 28 m × f
f = 0.25 Hz
Frequency = 1 / period
0.25 Hz = 1 / T
T = 4 s
A paint brush is dropped from the top of a tall ladder and free falls to the ground. What changes, if any, would be observed of the velocity and the acceleration of the brush as it falls? Pick the two answers. The velocity increases. The velocity decreases. The velocity remains a constant value. The acceleration increases. The acceleration decreases. The acceleration remains a constant value.
Answer:
Explanation:
As the paint brush is dropped from the top of a tall ladder it started free falling
i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.
We know acceleration due to gravity is the attraction experienced by the object due to earth attraction
Value of acceleration due to gravity is constant i.e. [tex]9.8\ m/s^2[/tex]
Therefore the correct choice is
velocity is increasing and acceleration is constant

Rohit placed a pencil perpendicular to principal axis in front of a converging
mirror of focal length 30 cm. The image formed is twice the size of the pencil.
Calculate the distance of the object from the mirror.
Answer:
45 cm ( in my opinion)♀️
Explanation:
( Using the mirror formula)
1/ u + 1/v = 1/f
( introducing magnification; m into the formula )
u( 1/u + 1/v ) =u×1/f
1 + u/v =u/f
( But u/v =1 ÷v/u= 1/m)
1 +1/m =u/f
(Supposing m is actually equal to 2, and f =30 cm, then;)1 + 1/2 =u/30
2+1= u/15
3=u/15
3×15=u
45 cm=u

Which phrases describe all the outer planets’ motion? Select two options.
no rotation
fast rotation
slow revolution
opposite revolution
north to south rotation
Answer:
Fast rotation
Slow revolution
Explanation:
Solar system has 8 planets. 4 inner rocky planets - Mercury, Venus, Earth and Mars and 4 outer gaseous planets - Jupiter, Saturn, Uranus and Neptune. The outer planets have few common features.
They are gaseous. There period of revolution is larger than the inner planets which means that they have slow revolution about the Sun. One day on the outer planets is smaller than the inner planets which means they have fast rotation.
For example, Jupiter has revolves around sun in 11.86 Earth years and rotates about axis in 9.8 Earth hours. Uranus revolves around sun in 84 Earth years and rotates on its axis 17.9 Earth hours.
Answer:
Fast rotation

You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is 2.0 amps, what is the
resistance?
A 12 ohms
B 0.75 ohms
C 3.0 ohms
D.0.5 ohms
E. 6.0 ohms
Answer:
The answer is "C. 3.0 ohms".
Explanation:
Ohm's law states the following:,
V = IR
where:
Voltage (V) = 1.5 volts × 4 batteries = 6.0 volts
Current (I) = 2.0 amps
Resistance (R) = ? ohms
To solve for Resistance (R) the equation must be rearranged this way:
R = V / I
Then, the variables must be replaced with the known values:
R = 6.0 volts / 2.0 amp
R = 3.0 ohms
The answer is C. 3.0 ohms.

What is the critical angle for glass when the refractive index is 1.45
Answer:43.6°
Explanation:
Refractive index=n=1.45
Critical angle=c
n=1/sinc
1.45=1/sinc
Cross multiply
1.45sinc=1
Divide both sides by 1.45
(1.45sinc)/1.45=1/1.45
sinc=0.6897
c=sin(inverse)(0.6897)
c=43.6°
Critical angle is 43.6°
