Answer:
a = 0.5 m/s²
Explanation:
the type of problem is called a Newtons second law of motion.
and the equation would be the <u>sum of F = m * a</u> where m = mass and a = acceleration
forces are 125N and the opposite direction is 120N
Eli pushes the table with a force of 120N towards Andy
and
Andy pushes the table with a force of 125N towards Eli
mass of table given as 10 kg.
using the equation
120N - 125N = 10kg * a
a = (120-125) / 10
a = -0.5 m/s² so the acceleration is in the direction of Andy's force towards Eli.
therefore a = 0.5 m/s²
Answer:
Because of the vibration of the string. since it is vibrating it will make the other air molecules vibrate as well and air vibrating is basically a sound wave.
Answer:
The time of travel and the distance between neighboring dots is always the same. So, the speed between neighboring dots is constant. This speed will be the same as the average speed in part F.

Answer:
Explanation:
The magnitude on the charge at the bottom-left corner due to the charge on the top vertex of the triangle will act along the +ve x-axis and the +ve y-axis.
From Coulomb's law the magnitude of the forces on the charge at the bottom-left corner, due to the charge on the top vertex of the triangle are cos 60, and
The magnitude on the charge due to the charge at the bottom-right corner will only act in the -ve x-axis, since they repel each other (like charges repel). The magnitude is
The angle made by the upper charge to the charge we're considering is 60° with the horizontal.
The total force on the charge along the x-axis is
= cos 60 -
= -
==> -
For the y-axis, we have
= sin 60
=
The resultant force is
The common factors between the two x-axis force, and the y-axis force is
, we put this outside the square root (squaring this and square rooting will give us the initial value)
=
=
==>
the magnitude of the electric force on the charge at the bottom left-hand vertex of the triangle due to the other two charges is
=
