Answer:
<em>The volume of water is 3.5 cubic meter</em>
Explanation:
<u>Density
</u>
The density of a substance or material is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
We are given the density of water as 
.It's required to find the volume of m=3,500 kg of water. Solving for V:
The volume of water is 3.5 cubic meter
Answer:
c) both technician A and B
Explanation:
- A communication network is a collection of the interconnected networks that are managed to support the transfer of the information form a user in one network location and to a user of the another node.
- Are connected as the link and to enable the communication and sharing of the data between the terminals and different modules. Hence both the A and B technicians are equally correct.
Answer:
Explanation: The equation that relates resistance of tungsten at different temperatures is as follows
R = R₀ [1 + α ∆T] , R₀ is resistance at lower temperature , R is resistance at higher temperature . α is temperature coefficient of resistivity and ∆T is rise in temperature .
Putting the values
170 = 26 [1 + .0045 ∆T]
∆T = 1230.75
lower temperature = 40◦C
higher temperature = 1230 + 40
= 1270◦C
