Answer:
b) Demultiplexer.
Explanation:
The multiplexed signal occupies the total bandwidth of the communications channel, while that the constituent component signals, occupy only a small part of the bandwidth.
Prior to be demodulated, they must be separated each other, which is done (in a FDM multiplexing scheme) using a series of band-pass filters.
Answer:
2000 pieces
Explanation:
The number of tiles is given by dividing the area of room by the area of each tile. In this case,
thw areas are as shown below
Area of room is 8*10= 80 m2
Converting dimensions of tiles from cm to m then
Area of tiles is 0.2*0.2= 0.04 m2
No of tiles is 80/0.04=2000 tiles
Answer:
P = 5880 J
Explanation:
Given that,
The mass of the block, m = 30 kg
The block is sitting at a height of 20 m.
The block will have gravitational potential energy. The formula for gravitational potential energy is given by :
So, the required potential energy is equal to 5880 J.
....possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors
The combination of depth at 10 m and the temperature of 15 °C will produce the greatest water pressure.
Explanation:
The pressure in any liquid is directly proportional to the depth of the water body. This is because, the more the depth, the more the buoyant force will be acting on the liquid surface. So if the water is kept constant at 15 °C, the volume is said to increase with increase in temperature as volume is directly proportional to the temperature. The same goes for pressure, the pressure of liquid increases with increase in temperature. So the combination of depth at 10 m and the temperature of 15 °C will produce the greatest water pressure.
