An electric dryer consumes 6.0 × 10^6 joules ofelectrical energy when operating at 220 volts for
1.8 × 103 seconds. During operation, the dryer
draws a current of
(1) 10. A (3) 9.0 × 102 A
(2) 15 A (4) 3.3 × 103 A

Answers

Answer 1
Answer:

Answer : The dryer draws a current of 15 A.

Explanation :

Given that,

Energy consumed, E=6* 10^6\ J

Voltage, V = 220 Volts

Time, t=1.8* 10^3\ s

Power dissipated is given by :

P=(E)/(t)

Also, P = VI

So, VI=(E)/(t)

I=(E)/(Vt)

I=(6* 10^6\ J)/(220\ V* 1.8* 10^3\ s)    

I=15\ A

So, the correct option is (2)

Hence, this is the required solution.                                                  

Answer 2
Answer:

The dryer draws a current of 15 A.Electric currents is the ratio of charge per unit of time.

What is electric current?

The pace at which electrons travel through a conductor is known as electric current. The ampere is the SI unit for electric current.

Electrons are tiny particles that reside within a substance's molecular structure.

The given data in the problem is;

V is the voltage= 220 volts

E is the electric energy= 6.0 × 10⁶

t is the time =1.8 × 10³ seconds.

I is the electric current=?

The electric current is found as;

\rm P= (E)/(t) \n\n\ P= VI \n\n VI = (E)/(t) \n\n I= (E)/(VT) \n\n I= (6 * 101^6 )/(220 * 1.8 * 10^3) \n\n \rm I= 15 A

Hence the dryer draws a current of 15 A.Electric currents is the ratio of charge per unit of time.

Which of the following best explains why clear-cutting forests is more destructive than selectively cutting down trees in forests?a. Clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals.
b. Clear-cutting places the land at greater risk for wildfires.
c. Clear-cutting makes land more attractive for human development.
d. Clear-cutting causes less soil erosion than selective cutting.

Answers

The answer is a. cutting trees reduce fertility and eliminates animal habitats. Plant material is essential in maintaing soil fertility. Leaves and branches decay to form humus; removing trees decreases the organic content. Trees are home to many animal species, including birds, insects and amphibians. Some trees are even support or home to other plants. Examples include epiphytes in the rainforest ecosystem. Clear cutting forests disrupts whole communities and ecosystems.

When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.Which identifies the energy transformations that take place in Anna’s body as this process takes place?

A: Mechanical energy is converted to kinetic energy, which is then converted to potential energy.
B: Chemical energy is converted to thermal energy and electrical energy.
C: Electrical energy is converted to chemical energy and thermal energy.
D: Mechanical energy is converted to potential energy which is then converted to kinetic energy.

Answers

The correct answer is

B: Chemical energy is converted to thermal energy and electrical energy.

In fact:

- initially, the energy is contained in the molecular bonds of the glucose, inside the sugars that Anna is eating, and this energy is in the form of chemical energy

- Part of this energy is converted into the electrical energy that make the heart beating, and this energy is in the form of electrical energy

- The rest of the energy is converted into heat for the body, and this energy is in the form of thermal energy

Answer: B. Chemical energy is converted to thermal energy and electrical energy.
