The difference between a fuse and a circuit breaker is that a fuse is a one time circuit element while a circuit breaker is a multiple use device. If you were designing a circuit for a reading lamp, you should include a circuit breaker so you don't have to replace it every time.
Answer:
a round shape. It has its own gravity to pull itself into a round shape
Answer:
2 × 10⁸J/kg
Explanation:
Specific latent heat of vaporization (steam) is the quantity of heat required or needed to change a unit of mass of liquid to gaseous state at constant temperature (boiling point) and pressure.
It can be calculated mathematically using,
Q = mL
Where, Q = quantity of heat
m= mass in kg
L = specific latent heat (J/kg)
Therefore,from the question
Q= 15000000J
mass (m) = 75g = 75/1000 kg = 0.075kg
Q = mL
L = Q/m
L = 15000000 ÷ 0.075
L= 200000000J/kg
L = 2 × 10⁸J/kg

Answer:
P = 9800 [Pa]
Explanation:
In order to calculate the pressure at the bottom, we must use the following formula.
P = Ro*g*h
where:
P = pressure [Pa] (units of pascals)
Ro = density of the water = 1000 [kg/m³]
g = gravity acceleration = 9.8 [m/s²]
h = height = 1 [m] (because its half of the portion, the full height is 2 m)
P = 1000*9.8*1
P = 9800 [Pa]
