Hi there!
Use the following equation: (Newton's Second Law)
∑F = ma, where:
∑F = net force (J)
m = mass (kg)
a = acceleration (m/s²)
Plug in the given values:
∑F = 1500 · 40 = <em>60,000 J</em>
The actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is mathematically given as
<h3>What are the actual mechanical advantage, the velocity ratio, and the length of the slope if the height of the slope is 10 m?</h3>
Question Parameters:
A block of weight 5000 N is pushed up a slope by a force of 250 N.
Generally, the equation for the actual mechanical advantage is mathematically given as
A=Fout/Fin
A=5000/250
A=20
b)
the velocity ratio is given by the distance moved by the effort divided by the distance moved by the load
Therefore
VR=250/5000
VR=0.05
c)
the length of the slope if the height of the slope is 10 m
Assume the slope is at an angle of 30
Hence
sin 30=10/x
x=20m

Yes it is ! Because u need to learn about weathering
La densidad del metal disminuye a medida que se calienta . Piense en el agua . Cuando hace frío , se convierte en hielo , lo cual es muy densa . Cuando hace calor , se evapora en gas , que no es denso.

Answer:
The Michelson-Morley was designed to detect the motion of the earth through the ether.
No such relation was found and the speed of light is assumed to be the same in all reference frames.
