Answer:
If magnitude of vector A is less than magnitude of vector B then its x-component will be also less
Explanation:
In first case magnitude can never be negative -ve sign shows the direction only so it is incorrect statement.
The magnitude of any vector can never be less than its component because component of vector is found with the multiplication of sine and cos angle which values lies between 0 and 1 so after multiplication it gives less value than the vector
If magnitude of any vector is less then its x component will also be less because magnitude of component is dependent on the magnitude of vector
One plate goes under another in the subduction zone. So for
the given question, the correct option is option “A”. Subduction rates are not
very high. They can be only a few centimeters per year and that is the reason
people do not feel the effect. The plates between which the shifting occurs can
either be oceanic crust or the continental crust. Mountain formations are
necessarily associated with subduction movements of plates. In such cases the
movements are huge and can result in earth quakes as well.
Answer:
gravity
Explanation:
That would make the most sense from what I know
Answer:
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Answer:
L = 0.99 m = 99 cm
Explanation:
The period is the reciprocal of the frequency.
T = 1/0.5 = 2.0 s
T = 2π√(L/g)
L = g(T/2π)²
L = 9.8(2.0/2π)² = 0.99 m
If the system accelerates upward, it will cause the apparent gravity to increase. This will require a longer pendulum to keep the same period, or shorten the period if the length remains the same. This shows up in the equation where the product of gravity and the square of the period must remain constant for the length to remain constant.
