Answer:
B
Explanation:
Mass is the amount of matter in an object. Weight is the force of gravity on an object.
Answer: 2 s
Explanation: Change in momentum is equal to impulse which is J= Fxt
Derive the equation to find t.
t= J/F = 60/30= 2
The given figure shows the arrangement of vectors
-B is acting with a magnitude of 25 with
So vector B is along the opposite direction of vector -B
Statement A is wrong since the direction is opposite
Statement B is also wrong since it makes
Statement C is correct since it has 25 m magnitude
Statement D is wrong because vector's magnitude cannot be negative.
So option C is the correct answer.
Answer:
False. Temperature is independent of volume
