What else can I help you with?
A river current has a velocity of 5 kmh relative to the shore. A boat moves in the same direction as the current at 4 kmh relative to the river. How do you calculate the velocity of the boat relative?
The velocity of the boat relative to the shore is the vector sum of its velocity relative to the river and the velocity of the river current. In this case, it would be 4 km/h (boat's speed) + 5 km/h (current's speed), which equals 9 km/h.
What is the relationship between depth and current speed?
As depth increases, current speed typically decreases due to friction with the riverbed. This is known as the velocity gradient, where the flow is faster at the surface and slower towards the bottom. It's important to consider this relationship when studying river dynamics or designing structures in rivers.
What is the relationship between current, charge, and velocity in an electrical system where the current is equal to the charge multiplied by the velocity?
In an electrical system where current is equal to the charge multiplied by the velocity, the relationship is that the current flowing through the system is directly proportional to both the amount of charge and the velocity at which the charge is moving. This means that as either the charge or the velocity increases, the current flowing through the system will also increase.
What is the difference between absolute path name and relative path name in Unix?
Absolute path: Path from root directory (it is the same place, wherever the current path is) Relative path: Relative to the current path.
What relation between electric current and drift velocity?
The drift velocity of free electrons in a conductor is directly proportional to the magnitude of the electric current flowing through the conductor. This means that as the current increases, the drift velocity of the electrons also increases. The relationship is described by the equation I = nAvq, where I is the current, n is the number density of charge carriers, A is the cross-sectional area of the conductor, v is the drift velocity, and q is the charge of the charge carrier.
Difference between velocity and current modulation in klystron?
Velocity modulation in a klystron involves the interaction between the electron beam's velocity and the RF field to produce amplification. Current modulation, on the other hand, involves varying the electron beam's current to control the amplification of the RF signal. In summary, velocity modulation affects the electron beam's speed, while current modulation affects the electron beam's density in a klystron.
How many paths are in a parallel circuits?
At least two paths. Current will divide between them according to their relative impedances.
How can produce an electric current by means of electric magnetic induction?
Create relative motion between a magnetic field and a loop of wire.
How many paths are there in a parallel circuit?
At least two paths. Current will divide between them according to their relative impedances.
What relative humidity is a comparison between?
The current water vapor content of the air (in question) AND the maximum amount of water vapor that it could carry.
How induced current produce?
when a conductor moves accross a magnetic field or when magnetic field moves with respect to a stationary conductor for current to be induced, there must be relative motion between the coil and the magnetic.
