Answer:0.502kg
Explanation:
F4om the relation
Power x time = mass x latent heat of vapourization
P.t=ML
1260 * 15 *60 = M * 22.6 * 10^5
M= 1134000/(22.6 *10^5)
M=0.502kg=502g
Answer:
a. 475.14 Hz
b. 1959 Hz
c. 2341.53 Hz , 3053.34 Hz
Explanation:

a. smallest use the capacitive 4.2 uF + 6.0 uF = 10.2uF replacing:


b. second smallest use the capacitive 6 uF so:


c. second largest and largest oscillation first combination so:
Use 4.2 uF


And finally largest oscillation cap in serie so:




Answer:
Explanation:
Given that,
Gas central heating was used for 5days
At a rate of 102kWh of energy
Then, 1 kWh = 7p
So,
The total time is 5days
t = 5days
1 day = 24hours
Then, t = 5days = 5 × 24 = 120hours
Given 102kWh, then, they consumers 102 kW in one hour, then, for the 120hours,
The total energy used is 102 × 24
Then, total energy = 2448 kWh
So, 1 kWh = 7p,
Then, 2448 kWh = 7 × 2448
2448 kWh = 17,136 p.
So, the cost of the using central heat is 17,136 p
In a solution, a SOLUTE is the substance being dissolved.
In a solution, a SOLVENT is the substance in which something is dissolved.
For example in salt water, the salt is the solute. And the water is the solvent. Usually, which substance has a larger amount in the solution can be called a solvent. It doesn't matter if it's a gas, solid, or liquid. They can all be solute or solvents.
