Clearly visible data points and appropriate labels on each access that include units
Answer:
The pressure remains the same.
F = P * A the amount of force transmitted would double if only the input area is changed. Pressure is the same at all points in the system.
Answer:negative charge, small relative mass, and found outside the nucleus
Explanation:
The electron is one of the subatomic particles. It is negatively charged and has a relatively small or somewhat negligible mass. It is found outside the nucleus on the orbits. The electron is bound to the nucleus by electrostatic forces of attraction in the Bohr's model of the atom.
Answer:
a. It is constant the whole time the ball is in free-fall
Explanation:
If we divide the movement on its vertical and horizontal components, and we concentrate on the vertical component, let's call x-component, and analyze Newton's second's law:

with
,
the acceleration on horizontal direction and m the mass of the ball, because the only force acting on the object is gravity that is always vertical, there're not forces on the horizontal direction that means
and by (1) that implies
=0 there's not acceleration on horizontal direction.
Because acceleration is the rate at what velocity changes and there's no acceleration, there's no change in velocity, in other words velocity is constant on horizontal direction.
Answer:
1.2 ft/s or 72 ft/min
Explanation:
To solve this problem, we can use the relationship between the angular and linear speed for this particular movement (rotation). As the speed of the current is tangent to the trajectory of the wheel we can define as follows:

The speed of the current is 72 ft/min
