Answer:
A
Explanation:
Iron and gadlinium are both very easily made into magnetic substances. Cobalt is also capable of being magnetized. Aluminum, put in an alloy, can make a magnetic substance, but
Aluminum by itself is not able to be magnetized.
P = √ [(px)^2 + (py)^2]
we know that px is 100 kg m/sec
and we know that py is 98 m/sec
So, to find out the momentum, you just need to insert the number into the equation
p = √(v1^2 + v2^2)
<span>p = </span>√<span>(98^2 + 100^2) </span>
<span>p = 140.01 </span>
<span>p = 1.4 x 10^2 k m/s</span>
1) There must not be credible contrary evidence to the ideas suggested by the theory.
2) The models and theories must obey the already established laws of physics. Laws are theories which have such an overwhelming amount of evidence that they are universa, and cannot be disproven.
The answer would be 6377830.272 meters
