Any unit of acceleration must have the dimensions (form) of
(a unit of length) / (a unit of time)²
Answer:
<em>50 m/s</em>
<em></em>
Explanation:
In a projectile motion, acceleration is only on the vertical plane, that is, the vertical velocity is the only velocity component that undergoes acceleration under gravitational force. The horizontal component of velocity dos not change with time, and hence is the same as the initial velocity of the projectile.
Considering the four electric charges forming a square with magnitude of charge of 2.0 nC on each. :
A) Magnitude of the force on the 5.5 nC charge in the middle of the figure = 3.48 * 10^-4 N
B) Direction of the force on the 5.5 nC charge in the middle of the figure = Leftward ( negative x -axis )
Using the given data :
size of square = 4 cm
magnitudes of four charges = 2.0 nC
<u> a) </u><u>magnitude</u><u> of the force on the center charge </u>
Electric force between two point charges = ----- ( 1 )
where ;
step 1 ; find r ( distance between charges )
r² = ( 2 )² + ( 2 )² = 8 cm²
back to equation 1
F = 9 * 10⁹ * = 1.23 * 10^-4 N
∴ magnitude of the force on the center charge ( Fnet )= 4F cos 45°
= 4 * ( 1.23 * 10^-4 ) * = 3.48 * 10^-4 N
b) The direction of the force at the center is along the negative x-axis ( leftward )

Answer: your feet are the foundation! Even though all your body parts are connected and affect one another, your feet are what we at Foot Levelers call, the "foundation".
Explanation:
Here we have a circular motion. In that type of motion two new forces appear: centrifugal and centripetal. Centrifugal force tries to move object away frome the center of rotation. Centripetal force is the reason why object moves in a circle.
According to Newton's first law, in order for water not to spill out total force acting on water must be equal to zero. Forces acting on the water are gravitational and centrifugal.

Forces have opposite signs as they act in opposite directions. But their value is the same so we can ignore signs:
