Answer:

- The necessary formula to find the force that Pedro must apply is

(Load) × (distance of Load from the fulcrum) = (Effort) × (distance of Edfort from the fulcrum)

- The force that Pedro must apply = 60 N

- La fórmula necesaria para encontrar la fuerza que Pedro debe aplicar es

(Carga) × (distancia de carga desde el punto de apoyo) = (esfuerzo) × (distancia de Edfort desde el punto de apoyo)

- La fuerza que debe aplicar Pedro = 60 N

Explanation:

English Translation

Pedro wants to move a 300N rock with a lever and it is placed 1.5 m from the fulcrum, the distance from the rock to the fulcrum is 30 cm. Select the necessary formula to find the force that Pedro must apply

Solution

The sum of clockwise moment must balance the sum of anti-clockwise moment.

Let the force that Pedro must apply = Effort = F

Taking moment about the fulcrum

(Load) × (distance of load from the fulcrum) = (Effort) × (distance of Edfort from the fulcrum)

Load = 300 N

Distance of Load from the fulcrum = 30 cm = 0.30 m

Effort = F

Distance of Effort from the fulcrum = 1.5 m

300 × 0.30 = F × 1.5

F = (300×0.30)/1.5 = 60 N

In Spanish/En español

La suma del momento en sentido horario debe equilibrar la suma del momento en sentido antihorario.

Deje que la fuerza que Pedro debe aplicar = esfuerzo = F

Tomando un momento sobre el fulcro

(Carga) × (distancia de carga desde el punto de apoyo) = (esfuerzo) × (distancia de Edfort desde el punto de apoyo)

Carga = 300 N

Distancia de carga desde el fulcro = 30 cm = 0.30 m

Esfuerzo = F

Distancia de esfuerzo desde el punto de apoyo = 1.5 m

300 × 0.30 = F × 1.5

F = (300×0.30)/1.5 = 60 N

Hope this Helps!!!

Find the ratio of the final speed of the electron to the final speed of the hydrogen ion, assuming non-relativistic speeds. Take
KiRa [710]

Answer:

\frac{V_{e}}{V_{h}}=0.428*10^{2}

Explanation:

From conservation of energy states that

K_{i}+v_{i}=v_{f}+K_{f}\\ as\\K_{i}=0\\K_{f}=1/2mv^{2}\\ v_{i}=qv\\v_{f}=0\\So\\qv=1/2mv^{2}\\ v=\sqrt{\frac{2qv}{m} }\\ Velocity_{electron}=\sqrt{\frac{2qv}{m_{e}} }\\Velocity_{hydrogen}=\sqrt{\frac{2qv}{m_{h}} }\\\frac{V_{e}}{V_{h}}=\sqrt{\frac{\frac{2qv}{m_{e}}}{\frac{2qv}{m_{h}}}}\\\frac{V_{e}}{V_{h}}=\sqrt{\frac{m_{h}}{m_{e}} }\\\frac{V_{e}}{V_{h}}=\sqrt{\frac{1.67*10^{-27} }{9.11*10^{-31} } }\\\frac{V_{e}}{V_{h}}=0.428*10^{2}

A string along which waves can travel is 4.36 m long and has a mass of 222 g. The tension in the string is 60.0 N. What must be
lora16 [44]

Answer:

frequency is 195.467 Hz

Explanation:

given data

length L = 4.36 m

mass m = 222 g = 0.222 kg

tension T = 60 N

amplitude A = 6.43 mm = 6.43 × 10^{-3} m

power P = 54 W

to find out

frequency f

solution

first we find here density of string that is

density ( μ )= m/L ................1

μ = 0.222 / 4.36  

density μ is 0.050 kg/m

and speed of travelling wave

speed v = √(T/μ)       ...............2

speed v = √(60/0.050)

speed v = 34.64 m/s

and we find wavelength by power that is

power = μ×A²×ω²×v  /  2     ....................3

here ω is wavelength put value

54 = ( 0.050 ×(6.43 × 10^{-3})²×ω²× 34.64 )   /  2

0.050 ×(6.43 × 10^{-3})²×ω²× 34.64 = 108

ω² = 108 / 7.160  × 10^{-5}

ω = 1228.16 rad/s

so frequency will be

frequency = ω / 2π

frequency = 1228.16 / 2π

frequency is 195.467 Hz

How much metabolic energy is required for a 68kg person to run at a speed of 15km/hr for 15min ?
irga5000 [103]
<span>What I have here is exactly the same problem, however, with the time changed to 19 mins:

metabolic energy = metabolic power*time = 1.150*19*60 = 1.311 kJ..corresponding to 1.311/4.186 = 313,2 Cal or kcal 

If we reasonably assume a metabolic eff.cy of 20%, it means we need to assume food for 1500 Cal approx.

Just plug the value t=15min to the equation and you will surely get the correct answer.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
