Explanation:
which element has 5 valence electrons and 4 shells
Answer:
Arsenic
Explanation:
Arsenic is in group 5 and period 4. Group numbers tell us the number of valence electron and period number tells us the number of shells in an element.
A non -viscous incompressible fluid is pumped steadily into the narrow end of a long tapered pipe and emerges from the wide end . The pressure at the input is greater than at the output . A possible explanation is :
Answer:
v₂ =[tex]( \frac{r_1}{r_2})^2 \ v_1[/tex]
Explanation:
This phenomenon is explained by the continuity equation in fluids
v₁A₁ = v₂A₂
where the subscript 1 is for the input narrow part and the subscript 2 for the wide part
v₂ = [tex]\frac{A_1}{A_2} v_1[/tex]
consider the cross section at each point
A₁ = π r₁²
A₂ = π r₂²
we substitute
v₂ =[tex]( \frac{r_1}{r_2})^2 \ v_1[/tex]
therefore the exit velocity is less than the entrance velocity of the fluid.
We can also analyze the situation using Bernoulli's equation
P₁ + ρ g v₁² + ρ g y₁ = P₂ + ρ g v₂² + ρ g y²
if we assume a horizontal system y₁ = y₂
P₁-P₂ = ρ g (v₂² - v₁²)
Which items would have this energy transformation: chemical energy -> mechanical energy?
Answer:
La transformación energética, transformación de la energía, conversión energética o conversión de la energía es el proceso de cambiar la energía de un tipo de energía a otro. En física, la energía es una cantidad que proporciona la capacidad de realizar un trabajo (por ejemplo, levantar un objeto) o proporciona calor. Además de ser convertible, de acuerdo con la ley de conservación de la energía, la energía es transferible a una ubicación u objeto diferente, pero no se puede crear ni destruir.
La energía en muchas de sus formas se puede utilizar en procesos naturales o para proporcionar algún servicio a la sociedad, como calefacción, refrigeración, iluminación o realizar trabajos mecánicos para operar máquinas. Por ejemplo, para calentar una casa, el horno quema combustible, cuya energía potencial química se convierte en energía térmica, que luego se transfiere al aire de la casa para elevar su temperatura.

What line in the sky is created by our revolution around the Sun?
Answer:
Ecliptic
Explanation:
You asked for the term that is used to describe Earth going around the sun
The ecliptic is the path the sun, moon, and planets take across the sky as seen from Earth. It best defines the plane of the Earth's orbit around the sun. The imaginary line can best be visualized in the days just before full moon.

when is the object at rest? in constant speed? accelerating?
Answer:
Answered in explanaion.
Explanation:
REST: When an object does not change its position with respect to its frame of reference or surrounding, then the object is said to be in the state of rest.
CONSTANT SPEED: When the object covers equal distance in equal intervals of time, the object is said to be moving with constant speed.
ACCELERATING: An object is said to be accelerating when the speed of the object increases with respect to time.

When the force of impact on an object is extended in time, does the impulse increase or decrease? Increases
Explanation:
Distinguish between impulses and momentum.Which is force x time and which is inertia in motion?Impulse=force x time;momentum is inertia in motion
what would be the mass of a rock falling from the sky if it hits the ground with a force of 147 N
Explanation:
we know,
F = mg
where m is mass of object and g = acc. due to gravity (9.8 ) m/ s^2
147 = m x 9.8
147/ 9.8 = m
15 = m
therefore mass of object = 15 kg
a 2kg book falls off the top of a 2.3m bookshelf. how much work is required to lift the book back to it's original position? gravity acceleration is 9.58 m/s ²
Answer:
44.068 J
Explanation:
From the question,
Work(W) = mgh............... Equation 1
Where m = mass of the book, g = acceleraton due to gravity, h = height.
Given: m = 2 kg, h = 2.3 m, g = 9.58 m/s²
Substitute these values into equation 1
W = 2×2.3×9.58
W = 44.068 J
Hence the work required to lift the book is 44.068 J

If a riding lawnmower engine exerts 19 hp in one minute to move the mower, how much work is done? (Hint convert: 1 watt equals 0.00135962 hp)
Answer:
Work done = 838470 Joules.
Explanation:
Given the following data;
Power = 19 hp
Time = 1 minute to seconds = 60 seconds.
Next, we would convert the unit of power in "hp" to "Watt."
1 Watt = 0.00135962 horsepower
x Watt = 19 horsepower
Cross-multiplying, we have;
19 = 0.00135962x
x = 19/0.00135962
x = 13974.5 Watts.
Now, to find the work done in moving the mower;
Work done = power * time
Substituting into the formula, we have;
Work done = 13974.5 * 60
Work done = 838470 Joules.
A motorcycle of mass 100 kilograms travels around a flat, circular track of radius 10 meters with a constant speed of 20 meters per second. What force is required to keep the motorcycle moving in a circular path at this speed?
Answer:
100/10 = 10 , 10 × 10 = 100÷20 = 5
I'm pretty sure its wrong
The force required to keep the motorcycle moving in a circular path is equal to 2000 N.
What is centripetal acceleration?The centripetal force can be described as perpendicular to the velocity in a circular motion. If the objects change their speeds in a circular motion and acceleration is produced which is directed toward the center.
The mathematical expression for the centripetal acceleration used:
a = v²/r
Where 'r' is the circle's radius and a is the centripetal acceleration.
Given, the velocity of the motorcycle, v = 20 m/s
The radius of the track, r = 10m
The centripetal acceleration, a = (20)²/ 2×10 = 20 m/s²
The mass of the motorcycle, m = 100 Kg
The force required to produce this acceleration to keep the motorcycle moving in a circular path at this speed can be calculated as:
F = ma = 100 × 20 = 2000 N

A 1.5 kg mass attached to an ideal spring oscillates horizonatlly with an amplitude of 0.30 m. The spring constant is 85 N/m. What is the period of the mass's motion?
Answer:
T = 0.83 seconds
Explanation:
Given that,
The mass attached to the spring, m = 1.5 kg
The amplitude of the spring, A = 0.3 m
The spring constant of the spring, k = 85 N/m
We need to find the period of the mass's motion. The time period in spring mass system is given by :
[tex]T=2\pi \sqrt{\dfrac{m}{k}} \\\\T=2\pi \sqrt{\dfrac{1.5}{85}} \\\\T=0.83\ s[/tex]
So, the period of the mass's motion is 0.83 seconds.
