Radiation damages the cells that make up the human body, it can even cause cancer
Answer:
The vehicle displacement is 9.90 feet.
Explanation:
Given that,
Height of tree = 4.5 feet
Distance = 33 feet
According to figure,
We need to calculate the value of l
Using Pythagorean theorem
![l=\sqrt{(33)^2+(4.5)^2}](https://tex.z-dn.net/?f=l%3D%5Csqrt%7B%2833%29%5E2%2B%284.5%29%5E2%7D)
We need to calculate the vehicle displacement
Using horizontal component
Vehicle displacement =horizontal component of pulled rope
![Vehicle\ displacement= d\cos\theta](https://tex.z-dn.net/?f=Vehicle%5C%20displacement%3D%20d%5Ccos%5Ctheta)
Where,
is angle between rope and ground
d = pulled length of rope
![Vehicle\ displacement=10\times\dfrac{33}{\sqrt{(33)^2+(4.5)^2}}](https://tex.z-dn.net/?f=Vehicle%5C%20displacement%3D10%5Ctimes%5Cdfrac%7B33%7D%7B%5Csqrt%7B%2833%29%5E2%2B%284.5%29%5E2%7D%7D)
![Vehicle\ displacement=9.90\ feet](https://tex.z-dn.net/?f=Vehicle%5C%20displacement%3D9.90%5C%20feet)
Hence, The vehicle displacement is 9.90 feet.
Answer:
Txomin lifted the stone with greater mass. (Txomin levantó la roca con mayor fuerza).
Explanation:
The sportsman that lifts the stone with a greater mass needs a higher force (El deportista que levanta la piedra con mayor masa necesita una mayor fuerza):
José
![F = (200\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)](https://tex.z-dn.net/?f=F%20%3D%20%28200%5C%2Ckg%29%5Ccdot%20%5Cleft%289.807%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%5Cright%29)
![F = 1961.4\,N](https://tex.z-dn.net/?f=F%20%3D%201961.4%5C%2CN)
Txomin

![F = 2157.54\,N](https://tex.z-dn.net/?f=F%20%3D%202157.54%5C%2CN)
Txomin lifted the stone with greater mass. (Txomin levantó la roca con mayor fuerza).
Consider that the bar magnet has a magnetic field that is acting around it, which will imply that there is a change in the magnetic flux through the loop whenever it moves towards the conducting loop. This could be described as an induction of the electromotive Force in the circuit from Faraday's law.
In turn by Lenz's law, said electromotive force opposes the change in the magnetic flux of the circuit. Therefore, there is a force that opposes the movement of the bar magnet through the conductor loop. Therefore, the bar magnet does not suffer free fall motion.
The bar magnet does not move as a freely falling object.
The best answer to this question is D. a god scientific question should be based on observations instead of just imagination.
Hope this helps.
