Parallel
In a parallel arrangement, the length of the fascicles runs parallel to the long axis of the muscle. Such muscles are either straplike like the sartorius muscle of the thigh, or spindle shaped with an extended belly, like the biceps brachii muscle of the arm. However, some scientists classify spindle-shaped muscles into a separate class asfusiform muscles.
Pennate
in a pennate pattern, the fascicles are short and they attach obliquely to a central tendon that runs the length of the muscle. Pennate muscles come in three forms:
<span><span>Unipennate, in which the fascicles insert into only one side of the tendon, as in the extensor digitorum longus muscle of the leg. </span><span>Bipennate, in which the fascicles insert into the tendon from opposite sides so the muscle “grain” resembles a feather.
The rectus femoris of the thigh is bipennate. </span><span>Multipennate, which looks like many feathers side by side, with all their quills inserted into one large tendon. The deltoid muscle, which forms the roundness of the shoulder is multipennate.</span></span>
Well count how many half lifes it would take to get from 1 to 0.125 first
1 to 0.5 - 1 half life
0.5 to 0.25 - 2nd half life
0.25 to 0.125 - 3rd half life
so essentially it would take 3 half lives to get to 0.125 kg of radium.
Now simply multiply the number of half lives with the half life value given
(3x1620) to get your answer as the number of years that it would take.

Answer:
The correct answer is c. the truck driver.
Any object is said to be the motion if its relative distance with respect to a reference point is keep on changing.
For example, a kid travelling through a train might seem to be stationary with respect to the seat. However, he would seem to be moving if we see him in respect to the railway track outside the train.
A reference point is anything (place, person or any object) used to determine if something or someone is in motion.
In the given situation, the distance between truck driver and bulldozer will remain the same throughout the journey as it is being placed on the back of the truck. Hence, the correct answer is truck driver.
