Answer:
-0.01052 m/s
Explanation:
M = mass of ship =
m = mass of shell = 1100 kg
v = velocity of shell = 550 m/s
u = recoil velocity of ship
As linear momentum is conserved
The recoil velocity of the ship taking the firing direction to be the positive direction is -0.01052 m/s
To solve this problem it is necessary to consider two concepts. The first of these is the flow rate that can be defined as the volumetric quantity that a channel travels in a given time. The flow rate can also be calculated from the Area and speed, that is,
Q = V*A
Where,
A= Cross-sectional Area
V = Velocity
The second concept related to the calculation of this problem is continuity, which is defined as the proportion that exists between the input channel and the output channel. It is understood as well as the geometric section of entry and exit, defined as,
Our values are given as,
Re-arrange the equation to find the first ratio of rates we have:
The second ratio of rates is
Answer:
<em>The current is 11 Amperes</em>
Explanation:
<u>Electric Current</u>
The electric current is defined as a stream of charged particles that move through a conductive path.
The current intensity can be calculated as:
Where:
Q = Electric charge
t = Time taken by the charge to move through the conductor
The current intensity is often measured in Amperes.
The charge passing through a point in a circuit is Q= 55 c during t=5 seconds, thus the current intensity is:
I = 11 Amp
The current is 11 Amperes
