Answer:
Explanation:
The magnitude of the electric field between two parallel conducting plates is defined as:
Here is the potential difference between the plates and d its separation.
The electric potential energy is defined as the product between the particle's charge and the potential difference:
Solving for and replacing in the electric field formula:
In this case we have a double charged ion, so :
We have to remember a point , which is ' the cart or spring rest on a smooth horizontal track ' , i.e., any frictional force doesn't take place.
<u>Explanation:</u>
a) According to the question the cart is pulled to position A and released, i.e., the velocity of the cart at A initially (say time,t=0) is 0 m/s ,then moves toward position E, where it reverses direction and returns again to position A , in the 2nd phase cart moves along A to E , the cart's velocity increase and again goes to zero at point E and again change the direction, hence
( File has been attached)
b) Let's , the distance between two consecutive points is x meter and the spring constant is k N.m
c) ( File has been attached)
d) Movinf Right
e) Moving left
Answer:
A large elliptical
Explanation:
A S0 type galaxy is a large elliptical.
Answer:
Frequency – The frequency of a wave is the number of waves that pass a given point in a certain amount of time. Frequency is measured in units called hertz (Hz), and is defined as the number of waves per second. A wave that occurs every second has a frequency of 1 wave per second (1/s) or 1 Hz.
The time taken is
Explanation:
The motion of the bullet is a uniform motion (=constant velocity), therefore we can use the following equation:
where
v is the speed of the bullet
d is the distance covered
t is the time taken
For the bullet in this problem,
d = 0.30 m is the distance travelled
v = 800.0 m/s is the speed
Solving for t, we find the time taken:
