On question 30, that is a displacement- time graph (DT). On this type of graph the gradient is equal to the velocity. B has the steepest gradient, then A and finally C
Now velocity is a vector quantity so it has a direction and speed ( speed doesn't have a fixed direction.)
on the DT graph im going to assume that movement B is a positive velocity with A and C being negative.
So by ranking these: A is the most negative, C is the least negative and B has to be the greatest as it is the only positive velocity.
Q31, The same type of graph is present, by looking at the gradients we can rank the largest and smallest velocities- speeds in the case of the question.
i'll skip my working out as its the same as before:
C, B, A and then D
the same idea as on Q30 applies to Q31 part b,
D,C,B then A
The answer is:
It can be disruptive to the whole banking system.
Left. Opposite of the direction the box is pushed.
By subtracting the value of absolute zero, also know as adding 273.15!
Answer:
L
Explanation:
For every action, there is an equal and opposite reaction.
As the moment of inertia if the gyroscope is 1/10 of that of the remainder of the satellite, the angular velocity of the satellite will be 1/10 that of the spun up gyroscope and in the opposite direction.
L = Iω
