the lambda baryon has the quark composition uds. which particle has the same electric charge as the lambda baryon?
Answer:
A particle that has the same charge as lambda baryon is a neutron.
Explanation:
A lambda baryon is a subatomic particle that is made up of three quarks - uds (up, down and strange). It contains the same number of protons and neutrons, and an isotopic spin of 1. It is a family of hadrons just like mesons.
A quark is a fundamental or basic particle that make up a matter. It can combine with two or more to form composite particles (e.g neutron or proton). These basic particles are held by a very strong attractive force. The composite particles are the constituents of the nucleus of an atom.
The particle that has the same electric charge as the lambda baryon is neutron.
What quarks as seen in Lambda?The lambda is known to be a baryon that is composed of three quarks. They are:
An upA down A strange quarkThe neutron is known to be a kind of subatomic particle that is often written as n or n⁰ . It is known to have a neutral charge and its composition is that of 1 up quark and 2 down quarks.

A+block+of+1.2kg+is+placed+on+an+included+plane+at+60°+to+the+horizontal.+Calculate.+a.The+force+that+will+make+the+block+to+slide+down+the+plane.B.The+coefficient+of+friction+.C.+The+normal+reaction+d.+The+friction+force
Answer:
a. 10.2 N b. 1.73 c. 58.8 N d. 10.2 N
Explanation:
a. The force that will make the block slide down the plane
This is the component of the block's weight along the plane F = mgsinθ where m = mass of block = 1.2 kg, g = 9.8 m/s² and θ = angle of incline = 60°.
So, F = mgsinθ = 1.2 kg × 9.8 m/s² × sin60°.= 10.18 N ≅ 10.2 N
b. The coefficient of friction
The coefficient of friction, μ = tanθ = tan60° = 1.73
c. The normal reaction.
This is equal to the vertical component of the block's weight. So, F = mgcosθ. Substituting the values for the variables from above, we have
F = mgcosθ = 1.2 kg × 9.8 m/s² × cos60°.= 58.8 N
d. The frictional force
Since the block does not slide, there is no net force on it. If f is the frictional force, then
F - f = ma. Since a = acceleration = 0,
F - f = 0
f = F = mgsinθ = 1.2 kg × 9.8 m/s² × sin60°.= 10.18 N ≅ 10.2 N

The maximum range of projectle is R° if projected at angle of 45°. It'll be 300% of Range of projectile if projected at angle? a) 30° b) 45° c) 60° d) 76° Correct answer with good explanation
Answer:
The maximum range is 300% of the range of the projectile is projected at an angle of 9.74°.
None of the options are correct.
Explanation:
Normally, ignoring air resistance, for projectile motion, the range (horizontal distance travelled) of the motion is given as
R = (u² sin 2θ)/g
where
u = initial velocity of the projectile
θ = angle above the horizontal at which the projectile was launched
g = acceleration due to gravity = 9.8 m/s²
The range is maximum when θ = 45°
R when θ = 45° is
R = (u² sin 90°)/g = (u²/g)
We are then told that this maximum range is 300% of the value obtainable for the range at a particular angle
Maximum range = 3R
(u²/g) = 3(u² sin 2θ)/g
Sin 2θ = (1/3)
2θ = sin⁻¹ (1/3) = 19.47°
θ = (19.47°/2) = 9.74°

2. Two children play a game of catch, running back and forth to catch each throw from the other. Assume the children are standing 5m apart with one child standing at the origin before the game begins.
The ball makes the following motions:
5 meters right, 8 meters left, 3 meters right, 6 meters left, 15 meters right, and 4 meters left.
Part A:
Calculate the total distance traveled by the child on the left.
Part B:
Calculate the total displacement of the child on the right.
Answer:
Part A: 24 m
Part B: 9 m
Explanation:
Part A:
The children takes turns so the child on the left moves with when the ball moves 5 meters right, 3 meters right, 15 meters right, while the child on the right moves with when the ball moves 8 meters left, 6 meters left, 4 meters left
The total distance traveled by the child on the left is given by the relation;
Initial position of the child on the left = 5 m
First motion of the child on the left = Distance to origin + first distance ball moved
∴ First motion of the child on the left = 5 + 5 = 10 m location of child = 5 m left
Second motion of the child on the left = location of child - position of the ball = 5 - (5 - 8 + 3) = 5 m left location of the child = 0 m
Third motion of the child on the left = location of child - position of the ball = 0 - (6 - 15) = 9 m right
Total distance traveled by the child on the left = 10 + 5 + 9 = 24 m
Part B:
First motion of the child on the right = Distance of child to origin + second position of ball
Initial location of the child on the right = 0 m
∴ First motion of the child on the right = 0 + (5 - 8) = -3 m location of child = 3 m left
Second motion of the child on the right = location of child - current position of the ball = 3 - 6 = -3 m left location of the child = -6 m
Third motion of the child on the right = location of child - position of the ball = -6 - 5 = 11 m right
Final location of the child on the right = 9 m right
Total displacement of the child on the right = Final location of the child on the right - Initial location of the child on the right 9 - 0 = 9 m.

MRU(movimiento rectilineo uniforme) un movil viaja en linea recta con una velocidad media de 12metros /segundos durante 9segundos y luego con una velocidad media de 4.8metros/segundos durante 7 segundos siendo ambas velocidades al mismo sentido. a) cual es el desplazamiento total del viaje de 16 segundos? b) cual es la velocidad media del viaje completo?
Answer:
a) 141.6m
b) 8.4m/s
Explanation:
a) to find the total displacement you use the following formula for each trajectory. Next you sum the results:
[tex]x_1=v_1t_1=(12m/s)(9s)=108m\\\\x_2=v_2t_2=(4.8m/s)(7s)=33.6m\\\\x_T=x_1+x_2=108m+33.6m=141.6m[/tex]
hence, the total distance is 141.6m
b) the mean velocity of the total trajectory is given by:
[tex]v_m=\frac{v_1+v_2}{2}=\frac{12m/s+4.8m/s}{2}=8.4\frac{m}{s}[/tex]
hence, the mean velocity is 8.4 m/s

Se debe usar una rampa de 5 m para elevar muebles que pesen 490 N hasta una plataforma a una altura de 2 m. Su propuesta de que la eficiencia de la rampa es del 100%, ¿cuál debe ser la fuerza requerida para levantar cada mueble en la rampa?
Answer:
F = 180 N
Explanation:
To find the required force you first calculate the angle of the ramp, by using the following relation:
[tex]sin\theta=\frac{2m}{5m}=0.4\\\\\theta=sin^{-1}(0.4)=23.57\°[/tex]
Next, you use the Newton second law to know what is the x component (in a rotated coordinate system) of the gravitational force:
[tex]F_x=mgsin\theta[/tex]
the required force must be, at least, the last force Fx. You know that the weight of the object is 490N = mg. Hence, you have:
[tex]F=F_x=(450N)sin(23.57\°)=180N[/tex]
the required force is 180N

An ant is on the pendulum bob of a clock. What would be its displacement in one time period?
Answer: the displacement is 0
Explanation:
Displacement is defined as the difference between the final position and the initial position.
now, one time period is defined as the time that the pendulum needs to do a full cicle (so after one time period, the position of the pendulum returns to the same place) this means that the final position and the initial position is the same, then the displacement is 0.

Una lancha sube y baja por el paso de las olas cada 3.2 segundos, entre cresta y cresta hay una distancia de 24.5 m. ¿cual es la rapidez con la que se mueven las olas?
Answer:
7.656 m/s
Explanation:
El sonido viaja a cierta velocidad y tiene una frecuencia y longitud de onda. La relación entre la velocidad del sonido (V), su frecuencia (f) y la longitud de onda (λ) es la misma que para todas las ondas, está dada por la ecuación:
V = fλ
pero f = 1/T
∴ V = λ/T
donde T es el período
Dado que:
período (T) es el tiempo necesario para subir y bajar = 3.2 s
La distancia entre dos crestas es la longitud de onda (λ) = 24.5 m
V = λ/T = 24.5 / 3.2 = 7.656 m/s
V = 7.656 m/s

Water in the Antarctica usually exists as ice ,making it very difficult to use the water or conduct experiments reqiring the water to be in liquid state .A coffee addicted physisits stationed at a research base requires about 0.8 kg of ice for his coffe on the hour
Answer:
2730.304 KJ
Explanation:
How much heat is required to convert 0.8 kg of ice at -35°C into steam at 100 C?
Given that:
mass of ice (m) = 0.8 kg = 800 g
Initial temperature ([tex]T_i[/tex]) = -35°C = 238 K
final temperature ([tex]T_n[/tex])= 100°C = 373 K
Specific heat of ice ([tex]S_i[/tex]) = 2.108 J/g.K
Specific heat of water ([tex]S_w[/tex]) = 4.18 J/g.K
Latent heat of fusion ([tex]L_f[/tex]) = 334 J/g.
Latent heat of vaporization ([tex]L_v[/tex]) = 2230 J/g.
[tex]\Delta T=T_n-T_i=373-238=135K[/tex]
Total heat (Q) required to increase the temperature of ice from the initial temperature of 238K to final temperature of 373 K is given by the equation:
[tex]Q=m\Delta TS_i+m\Delta TS_w+mL_f+mL_v\\Q=800(135)*2.108+800(135)*4.18+800*334+800*2230\\Q=227664+451440+267200+1784000=2730304J\\Q=2703.304KJ[/tex]

you were seated sank
into the mud. You and
the person driving the
Vehicle want to lift the
truck using a branch.
You apply a force of
600 N to the branch
which acts as a lever.
The rear of the truck
weighs 2,400 N. What
is the mechanical
gain of the lever arm?
Answer:
m = 4
Explanation:
We have,
You apply a force of 600 N to the branch which acts as a lever. It means it is input force, IF = 600 N
The rear of the truck weighs 2,400 N. It means it is output force, OF = 2400 N
The ratio of output force to the input force is equal to the mechanical advantage of the lever arm. It is given by :
[tex]m=\dfrac{2400}{600}\\\\m=4[/tex]
So, the mechanical gain of the lever arm is 4.

Answer: C. Galactic disk
Explanation:
The part of the Milky Way which allows the determination of it rotational direction is known as the Galactic disk. This disc are shaped because they contain gases which are rich and dynamically young. It is also a part of a group of a galaxies disc is a component of disc galaxies, known as spiral galaxies and lenticular galaxies.
Answer:
Galactic disk
Explanation:
Galactic disc's are composed mostly of the galaxy's stars and a gaseous component mostly composed of cool gas and dust. The stellar population of galactic discs tend to exhibit very little random motion with most of its stars undergoing nearly circular orbits about the galactic center. This circular orbit maintains the galaxy's rotation momentum.
as a car drives past a person standing on a sidewalk, the driver keeps a hand on the horn. how does the pitch of the horn differ for the driver and the person standing on the sidewalk?
Answer:
While the car is going towards the standing person on the sidewalk he is listening the pitch of the horn higher then it is.
When the car passes the person on the sidewalk and goes away, the horn's pitch become lower (for the person standing on the sidewalk).
For the driver, the pitch is always the same.
Explanation:
Is the doppler effect.
When the car is approaching, the sound waves must travel a smaller space than the previous one and they take less time to reach the standing person. So, sound waves reach the standing person with a higher frequency.
It happens the opposite when the car is going away: the sound waves need to travel more space and take more time to reach the person on the sidewalk. So, the frequency of the waves is lower.
