A)Alpha
B)beta
C)gamma
D)positron
Answers
The radioactive decay is shown in the image attached to this answer
Answer:
Alpha
Explanation:
An alpha decay is said to have occurred when the mass number of the daughter nucleus decreases by four units and the atomic number of the daughter nucleus decreases by two units.
If we look at the equation from left to right, we will notice that the mass number of the daughter nucleus decreased by four units and the atomic of the daughter nucleus number by two units compared to that of the parent nucleus leading to the emission of an alpha particle.

Fundamentally, pressure is defined as force per unit area. What is the source of the force in a gas sample? A) The force is from gravity acting on the particles. B) The force is composed of the sum of the collisions only between gas molecules. C) The force is composed of the sum of the collisions only between the gas molecules and the container. D) The force is composed of the sum of all collisions--between the gas molecules, each other and the container. E) The force was imparted to the container in its initial filling, a transfer of momentum.
Answers
Answer:
Option C
Explanation:
Given
Pressure = Force /Area
For any gas sample, force is defined as basically the force exerted by the gas molecules when they strike the surface (with in which they are contained) and bounce back.
Hence, Option C is the correct
Un móvil posee un movimiento uniformemente acelerado, con una velocidad inicial de 20 m/s y aceleración 1,5 m/s. ¿Qué velocidad tendrá cuando hayan transcurrido 2 minutos? ¿Qué espacio habrá recorrido durante ese tiempo?
Answers
Answer:
La velocidad que tendrá el móvil cuando hayan transcurrido 2 minutos es 200 m/s.
El espacio que habrá recorrido el móvil durante 2 minutos es 13200 metros.
Explanation:
El movimiento rectilíneo uniformemente variado o MRUV es un movimiento que ocurre sobre una línea recta con aceleración constante. En otras palabras, un cuerpo realiza un movimiento rectilíneo uniformemente variado cuando su trayectoria es una línea recta y su aceleración es constante y distinta de 0. Esto implica que la velocidad aumenta o disminuye su módulo de manera uniforme.
La velocidad que tendrá un móvil luego de un tiempo t será:
v= v0 + a*t
donde v0 es la velocidad inicial y a es la aceleración.
En este caso v0= 20 m/s, a=1,5 m/s² y t=2 minutos= 120 segundos. Reemplazando y resolviendo se obtiene:
v= 20 m/s + 1.5 m/s²* 120 segundos
v= 200 m/s
La velocidad que tendrá el móvil cuando hayan transcurrido 2 minutos es 200 m/s.
La expresión de la posición en función del tiempo para el movimiento uniformemente variado es:
x= x0 + v0*t + [tex]\frac{1}{2}[/tex] *a*t²
donde x0 es la posición inicial, v0 es la velocidad inicial y a es la aceleración.
En este caso x0= 0 m, v0= 20 m/s, a=1,5 m/s² y t=2 minutos= 120 segundos. Reemplazando y resolviendo se obtiene:
x= 20 m/s* 120 s + [tex]\frac{1}{2}[/tex] * 1.5 m/s² *(120 s)²
x= 2400 m + 10800 m
x= 13200 m
El espacio que habrá recorrido el móvil durante 2 minutos es 13200 metros.
how does a force pumb works
Answers
Answer:
A force pump can be used to raise water by a height of more than 10m, the maximum height allowed by atmospheric pressure using a common lift pump.
In a force pump, the upstroke of the piston draws water, through an inlet valve, into the cylinder. On the downstroke, the water is discharged, through an outlet valve, into the outlet pipe.
A man is driving his 1100 kg car at 36 km/h on a straight freeway. After accelerating for 30 seconds, the car
has a speed of 108 km/h. How much work did the engine do during the 30 seconds?
Answers
Answer:
W = 439998 J = 439.99 KJ
Explanation:
First, we will calculate the acceleration of the car by using the first equation of motion:
[tex]v_f = v_i + at\\\\a = \frac{v_f-v_i}{t}[/tex]
where,
a = acceleration = ?
vf = final speed = [tex]108(\frac{km}{h})(\frac{1000\ m}{1\ km})(\frac{1\ h}{3600\ s})[/tex] = 30 m/s
vi = initial speed = [tex]36(\frac{km}{h})(\frac{1000\ m}{1\ km})(\frac{1\ h}{3600\ s})[/tex] = 10 m/s
t = time = 30 s
Therefore,
[tex]a = \frac{30\ m/s - 10\ m/s}{30\ s}[/tex]
a = 0.67 m/s²
Now, we will calculate the force applied by the engine:
F = ma
where,
F = force = ?
m = mass = 1100 kg
Therefore,
F = (1100 kg)(0.67 m/s²)
F = 733.3 N
Now, we will calculate the distance covered by the car by using the second equation of motion:
[tex]s = v_it+\frac{1}{2}at^2\\\\s = (10\ m/s)(30\ s)+\frac{1}{2} (0.67\ m/s^2)(30\ s)^2[/tex]
s = 600 m
Now, the work done (W) by engine can be calculated as follows:
W = Fs
W = (733.3 N)(600 m)
W = 439998 J = 439.99 KJ

Recessive alleles only show their effect if the individual has two copies of the allele.
Explanation:
Dominant and Recessive Alleles If your allele pair is FF or Ff, you will have freckles. The only way you can escape a freckled face is to inherit the recessive gene from each parent, giving you the ff allele pair. In general, recessive alleles show up in your phenotype only if you have two of them.

This lens is called the objective, because it's nearest to the object you're looking at.
If 30.45 grams of water is to be heated up 3.3 degrees to make baby
formula, how much heat must be added? The specific heat of water is
4.18 J/g °C.
A. 420 J
B. 281 J
C. 1604 J
D. 410 J
Answers
Answer:
A. 420 J
Explanation:
Given the following data;
Mass = 30.45 g
Specific heat capacity = 4.18 J/g °C.
Temperature = 3.3°C
To find the quantity of heat;
Heat capacity is given by the formula;
[tex] Q = mct [/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
t represents the temperature.
Substituting into the equation, we have;
[tex] Q = 30.45 * 4.18 * 3.3 [/tex]
Q = 420.03 ≈ 420 Joules
