Please I need help ill give u 50 points

In Physics, displacement is the distance and direction of the shortest path
from the starting point to the ending point, regardless of the path followed
to get there.

In California the pacific plate slides past the North American plate. If the pacific plate is moving at a speed of 5 centimeters

RUDIKE [14]

Answer:

2000years

Explanation:

We will either convert the distance to centimeters or speed to meters/second.

Converting distance to centimeters: 100 meters= 100*100centimeters =10000centimeters.

time=distance/speed

t=10000/5=2000 years

Suppose that each component of a certain vector is doubled. (a) by what multiplicative factor does the magnitude of the vector c

gladu [14]

<span>a. The magnitude of the vector is doubled as well. Let's say we have a 2-dimensional vector with components x and y. It's magnitude lâ‚ is given by: lâ‚ = âš(xÂ˛ + yÂ˛) If we double the components x and y, the new magnitude lâ‚‚ is: lâ‚‚ = âš((2x)Â˛ + (2yÂ˛)) With a bit of algebra... lâ‚‚ = âš(4xÂ˛ + 4yÂ˛) lâ‚‚ = âš4(xÂ˛ + yÂ˛) lâ‚‚ = 2âš(xÂ˛ + yÂ˛) We can write the new magnitude lâ‚‚ in terms of the old magnitude lâ‚. lâ‚‚ = 2lâ‚ Therefore, the new magnitude is double the old one. It should be clear that this relationship applies to 3D (and 1D) vectors as well. b. The direction angle is unchanged. The direction angle Î¸â‚ for a 2-dimensional vector is given by: Î¸â‚ = arctan(y / x) If we double both components, we get: Î¸â‚‚ = arctan(2y / 2x) Î¸â‚‚ = arctan(y / x) Î¸â‚‚ = Î¸â‚ The new direction angle is the same as the old one.</span>
