Answer:
The potential between the plates will decrease.
Explanation:
An insulator is usually placed between the parallel plates and is also called a dielectric because it makes the amount of charge a capacitor can accommodate to increase at a particular potential difference.
Furthermore, the dielectric effect will make the electric field of the charged capacitor which is not connected to a source of supply to decrease.
Now, when the battery is removed, the charge Q remains constant and Capacity C will increase.
Formula for the potential difference is here;
V = Q/C
Since the numerator Q is constant and the denominator C increases, it means the potential difference V will decrease
Answer:
first you have to organize the data. a=acceleration t=time v0=inicial velocity vf=final velocity
a=2.92m/s2
t=5.1s
vf=?
v0=0
now the formula you have to use is: vf=vi+a*t (final velocity equals to inicial velocity plus acceleration times time)

i was the best at my class, hope it helped
Thank you for posting your question your question here. Below is the solution:
time = 3.00 / 1.75
<span>time = 1.714 </span>
<span>now </span>
<span>distance = (initial velocity + final velocity) / 2 * time/ 1 </span>
<span>Hence</span>
<span>3 = ( 1.75 + final velocity) / 2 * 1.714 </span>
<span>3.5 - 1.75 = final velocity </span>
<span>Therefore, the final velocity is 1.75 m /s</span>
Answer:
a = 5.65 m/s² (↑)
Explanation:
T = 34.012 N (↑)
m = 2.2 Kg
g = 9.81 m/s²
We apply Newton's 2nd Law as follows:
∑ Fy = m*a
⇒ T - W = m*a
⇒ T - m*g = m*a
⇒ a = (T - m*g) / m
Finally
⇒ a = (34.012 N - 2.2 Kg*9.81 m/s²) / 2.2 Kg
⇒ a = 5.65 m/s² (↑)
All I know is that 5 is melanin
