False because their are single cell organisms
Answer:
Explanation:
Given that,
Displacement in North = 11 km
Displacement in East = 11 km
We need to find the approximate displacement of the hiker from the camp. It can be calculated by resultant of two displacement as follows :
Hence, the approximate displacement of the hiker from the camp is .
Answer:
somewhere between 32 m/s and 2 m/s
Explanation:
If the acceleration is applied in the same direction as the original motion, the motion increases.
17 + 3(5) = 32 m/s
If the acceleration is applied in the opposite direction as the original motion, the motion decreases.
17 - 3(5) = 2 m/s
If the acceleration is applied at an angle to the original motion, then we need to vector add original 17 m/s and the acceleration caused 15 m/s to find the final result. We would need the angle in ANY of these cases as velocity is a vector.
<h2>
Option B is the correct answer.</h2>
Explanation:
Period of a spring mass arrangement is given by
where m is mass and k is spring constant.
So period of spring mass arrangement is independent of amplitude of motion.
Here amplitude changes from A to 2A.
Period for amplitude A is given by T.
Since period remains same for amplitude 2A also, the period is T.
Option B is the correct answer.
