"The marble moved 30 cm north in 6 seconds" is the one example among the following choices given in the question that <span>provides a complete scientific description of an object in motion. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer has helped you.</span>
Answer:
A
Explanation:
Formula for Equivalent Resistance :
Solving :
R = 3.33 Ω
<span>The fact that muscles will improve in strength and conditioning in response to resistance training is called MUSCLE HYPERTROPHY.
This occurs because during resistance training the muscles develop very small tears, called micro-tears, that eventually heal and become scar tissues. As the scar tissues continue to increase, muscle fibers are said to bulk up creating that big and muscular physique that you see in people who are into resistance training.</span>
Let the salmon jump with speed v at an angle of 33.3 degree
So here we can find out the components of his velocity in x and y direction
now the horizontal displacement of the salmon is 3.15 m so he cover this horizontal distance with constant speed as there is no acceleration in x direction
here we can say
now in Y direction it is an accelerated motion as it is accelerated due to gravity
now we will plug in v*t = 3.76
now speed v is given by equation above
so here he must have to jump with minimum speed of 5.25 m/s
By the laws of reflection, we know,
Angle of reflection = Angle of incidence
angle of reflection = 30%
In short, Your Answer would be 30
Hope this helps!
