<span>Answer:
The spring force at A and B can be obtained
directly by summing moments_aJx)ut points B and A. respectively.
(+ IM, = 0; F A (1)- 392.4(3) =0 F A = 1 177.2 N
C+ 1M a = 0; F, (1) -392.4(4) = 0 F, = 1569.6 N
Spring Formula : Applying A = - , we have
Inn I S ,
A a = - 1 . 177 ' -- = 0.07*48 m A, = 156 ~ = 0. 10464 ra

A magnetic field. that's how people make magnets, by wrapping copper wire around whatever they want to be magnetic then running electricity through the wire. it works on revers to make electricity.

Answer:
Explanation:
To solve this problem we have to take into account that the energy consumed per second is the power. Hence, by multipling the power and the time spent to arrive to the lab we obtain the total energy consumed.
But first we have to calculate the time
Now we use E=W*t for both times
A. Hence, by running the energy consumed is lower.
B.
E1=1008000J
E2=1392000J
C. Because the more intense exercise is made in a lower time in comparison with the less intense exercise, and higher the time, more energy is consumed.
Answer:
True
Explanation:
Gamma rays and X-rays are made of packets of energy (photons) without mass or charge, with high penetrating power such that they can pass through the human body and impinge on a photographic plate creating an image of the interior of the human body. They electromagnetic radiation of high energy and high frequency that emanate from some natural sources such as cosmic sun rays and radon gas.
Gamma rays and X-rays can be man made by use of man made electronic devices and radioactive elements
Gamma rays and X-rays find use in airport security scanning and imaging services for medical testing.
