Answer:
A. 46.15 ohms
B. 1248 W
C. 2.25×10⁶ J
Explanation:
A. Determination of the resistance.
Current (I) = 5.2 A
Voltage (V) = 240 V
Resistance (R) =?
From ohm's law,
V = IR
240 = 5.2 × R
Divide both side by 5.2
R = 240 / 5.2
R = 46.15 ohms
B. Determination of the power.
Current (I) = 5.2 A
Voltage (V) = 240 V
Power (P) =?
P = IV
P = 240 × 5.2
P = 1248 W
C. Determination of the energy.
Power (P) = 1248 W
Time (t) = 30 minutes
Energy (E) =?
Next, we shall convert 30 minutes to seconds. This can be obtained as follow:
1 min = 60 s
Therefore,
30 min = 30 min × 60 s / 1 min
30 min = 1800 s
Finally, we shall determine the energy. This can be obtained as illustrated below:
Power (P) = 1248 W
Time (t) = 1800 s
Energy (E) =?
E = Pt
E = 1248 × 1800
E = 2.25×10⁶ J
Answer:
S & O
Explanation:
Electrons can be shared when both atoms are non-metal.
(called Covalent Compound)
Answer:
This causes higher average tidal ranges. The gravitational pull of the Sun and moon on Earth combined cause high tides that will be higher and low tides that will be lower than average.
Answer:
Inertia
Explanation:
The term for the tendency is inertia.
<em>The inertia of a body is the tendency of the body to remain unmoved when at rest and the tendency to keep moving when in motion. In other words, it is the tendency of a body to remain in a state of rest or motion. </em>
A static body will remain in a state of perpetual rest if no force acts on it and a moving body will keep moving in the same direction if no force acts on it. The force that needs to be overcome in order to change the state of the object is otherwise known as inertia force.
