A dryer runs on 240 V with a resistance of 30.0 Ω. What is the current of the dryer?
Answers
Answer:
Current, I = 8 Amps
Explanation:
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Given the following data;
Resistance, R = 30 ohms
Voltage, V = 240V
To find the current;
Current, I = 8 Amps
Therefore, the current of the dryer is 8 Amperes.

Answer:
12m/s²
Explanation:
Two balls with equal masses and speed engage in a head-on elastic collision. Since the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero.
Therefore, the second ball experience an acceleration of 12m/s² at the same time.
Final answer:
Due to the law of conservation of momentum, two balls of equal mass colliding will experience equal but opposite accelerations at the simultaneous point of collision. In this case, if one ball experiences an acceleration of 12m/s^2, the other will experience -12m/s^2.
Explanation:
In the field of physics, this scenario falls under the law of conservation of momentum. According to this law, the total momentum before and after the collision remains the same. If two balls of equal mass collide, and one experiences an acceleration of 12 m/s2, the other ball will experience an equal but opposite acceleration, so -12 m/s2. Please keep in mind, that this is a simplification and real-life situations might be more complex due to factors like friction, air resistance and the angle of collision.

Unit Cell
Explanation:
- A unit cell is the smallest fundamental particle of a crystal structure that represents the structure of a crystal.
- Long-range, three-dimensional repetitiveness of this unit cell forms a crystal. A unit cell is composed of ions or atoms in a particular arrangement forming a well-defined structure.
- Crystal have a sharp melting and boiling point and when cut using a tool, they give a sharp edge on the pieces.
b. the earth is not hot enough.
c. geothermal energy is intermittent.
d. geothermal sources do not have enough energy to generate electricity
Answers
Answer:
a. Limited to certain regions.
Explanation:
It will be wrong to say that the earth is not hot enough, geothermal energy is intermittent or this source is not enough to generate electricity. It is not the fuel, it's the earth which is continuously emitting radiation or heat and it will keep on emitting that. So it's the most consistent source of energy and is abundant enough to produce electricity. So the problem is, it's the location specific source of energy and can only be utilized at the places lying at the edges of the tectonic plates. So the correct option is a.
B. Electrical energy
Among the choices given, the type of energy associated with electric currents is electrical energy. By its definition, electric current is the flow of charged particles through a conductor or a conduction medium, for example, a wire. Basically, it involves electricity. It is similar to water current but instead of water molecules, charged particles move down a conductor. These charged particles are mostly electrons which move freely and at random. When all the free electrons move in the same direction, a current is created.

The range is 15.15 m and the time in the air is 1.01 s
Explanation:
Horizontal Motion
When an object is thrown horizontally (with angle 0°) with a speed v from a height h, it follows a curved path ruled exclusively by gravity until it eventually hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:
To calculate the time the object takes to hit the ground, we use the equation below:
The cannon is shot from a height of h=5 m with an initial speed of v=15 m/s. The range is calculated below:
d = 15.15 m
The time in the air is:
t = 1.01 s
The range is 15.15 m and the time in the air is 1.01 s
