Answer:
<em>| Fn | = 258 N</em>
Explanation:
<u>Net Force</u>
The net force vector is the sum of all the force vectors applied to a body.
There are four forces applied to a car:
325N to the north
175N to the south
465N to the east
255N to the west
To simplify the calculations, we find the net force by each axis separately, considering forces to the right and upward as positive.
Fx = 465 N - 255 N = 210 N
Fy = 325 N - 175 N = 150 N
The magnitude of the net force is:
| Fn | = 258 N
Answer:
true
Explanation:
The rest of the tectonic plate gets dragged along with the oceanic lithosphere, and this causes the plates to move. Convection is another driving force behind the plate tectonics. Convection refers to specific cells that are present in the Earth’s mantle.
Answer:
For the first one I think that depending on how high up you put the skater effects how fast/the velocity is.
For B I don't know
And for C I think that it depends on where you were to put it, if you put it somewhere down low, then it's energy would be really low compared to if you were to put the skater on a high ramp, the gravity pulling down on it would give it a greater force
Sorry I wasn't too helpful with it, did my best!:) And sorry if it's too late to use these for you
Explanation:
For A if you put the skater way up high when it came down all the gravity pulling down on the skater would cause it's/ there velocity to become greater because of the force pushing down on it (AKA Kinetic Energy)
Positive ions have lost one or more electrons so have a positive charge rather than a neutral one.
