The vertical component is B) 7.9 m/s
Explanation:
A vector can be resolved into its horizontal and vertical components. The horizontal and the vertical components form the sides of a right triangle, in which the resultant corresponds to the hypothenuse, so we can use Pythagorean's theorem:
where
R is the resultant vector
Rx is the horizontal component
Ry is the vertical component
In this problem, we have:
R = 12 m/s is the resultant vector
Rx = 9 m/s is the horizontal component
Solving the formula for Ry, we find the vertical component:

Answer:
sine the resistors are connected in series, we could add the sum and that single value replaces the individual resistors in series. therefore, 100ohm resistor can do.
Answer:
Acceleration = Passing a car on the highway/Any change in speed or direction/Slowing down to turn at an intersection
Friction = The force that opposes motion/The wheels moving against the road
Newton's first law = An object in motion stays in motion unless acted on by an outside force
Newton's second law = The harder you kick a ball the faster it will travel
Answer:
quasars are massive celestrial bodies that are far or remotely placed emitting large energy radiations.
parallax is the best way of determining distances between astronomical bodies and parallaxes of stars are measured relative to a quasar to minimise the measurement error. each observations is stimulated with the basic angle variations leading to minimum uncertainty in the results as the assumptions in the measurements are as minimal as possible.
