Answer:
t = 0.25 seconds
Explanation:
Given that,
Initial speed of a bullet, v = 800 m/s
Distance from the target is 200 m
We need to find the time required for the bullet to reach the target. Time is simply calculated by the definition of velocity i.e.
So, it will take 0.25 seconds to reach the target.
The acceleration is defined as the rate of change of velocity.
So, if the acceleration is zero, this means that the rate of change of velocity is zero, which also means that the body is moving with constant velocity.
Since we are given that the net forces acting on the body is zero, this means that the body is at equilibrium
Based on this:
<span>All forces on the bullets cancel so that the net force on a bullet is zero, which means the bullet has zero acceleration and is in a state known as equilibrium.
Note that if this constant velocity is equal to zero, then the body would be at rest (not moving)</span>
A heavy rainfall will fix two things to rocks and soil.
First the extra water just makes them denser. The additional weight may be just
sufficient to let things to move. Second, the rainwater becomes into all of the
openings of the soil or round the rocks. This can perform as an emollient to assist
the particles or the rocks start touching down the slope in the development of
mass wasting.
Frequency division multiplexing operates by dividing the signal into different frequencies
<u>Explanation:</u>
The technique that is used in the networking is the Frequency Division Multiplexing. using this technique, the existing bandwidths can be partitioned into different frequency bandwidths. These are not interrupting with each other. Each bandwidth can be used for carrying signals individually.
Using this technique many users can share a particular communication medium and they will not be interrupted with each other's communication.Hence this technique can also be termed as Frequency Division Multiple Access.
