The plates of a parallel-plate capacitor are maintained with a constant voltage by a battery as they are pushed together, withou
UNO [17]

Answer:

<em>The amount of charge increases.</em>

<em></em>

Explanation:

For a capacitor that has its plates still connected to a battery, the voltage on the capacitor remains constant. If the distance between the two plates of this capacitor is decreased, the capacitance will increase, and then the charge on the plate will increase in accordance with the relationship

Q =CV

From this relationship, if V is held constant, then Q has to increase for C to increase also.

A baseball has a momentum of 6.0 kg m/s south and a mass of 0.15 kg. What is the baseball’s velocity? Show work
kupik [55]

Momentum of an object is defined as product of mass and velocity

so it is given as

P = m* v

here it is given that

mass = 0.15 kg

momentum = 6 kg m/s

so by plug in values in the above equation

6 = 0.15 * v

v = \frac{6}{0.15}

v = 40 m/s

so its speed will be 40 m/s
