(b) Lorna then built a different circuit as shown below. How could Lorna get both bulbs to light at the same time in this circuit?
(b) Lorna then built a different circuit as shown below. - 1

Answers

Answer 1
Answer: Lorna should close the switches S3 and S4,and leave them closed.
Then, both bulbs are controlled by S5. 
When it's closed, they both light. When it's open, they're both off (dark).

WHAT IS THE IMPORTANCE OF THE TROPIC OF CANCER AND TROPIC OF CAPRICORN

Answers

The tropic of cancer and tropic of capricorn has inportance in geographical studies. They help to divide the oceans. They help to classify different countries ( as lying in and around of either of the zones). On classifying, we can also predict weather or atmospheric pressure over the country ( with respect to tropic of cancer or tropic of capricorn). Thus, it has important role in geography. 
they help the divide the world and describe the difference in weather patterns

I don't understand these following questions, can someone please help me?1) find the work done by a 25 N force applied for 6 meters
2) calculate the potential energy of a 5 kg object sitting on a 3 m ledge
3) a rock is at the top of a 20 meter tall hill, the rock has a mass of 10 kg. how much potential energy does it have?

Answers


These questions are testing to see if you know
the formulas for work and potential energy ... or
if you know where to find them when you need them.

1).  The formula for work is:

                       Work = (force) x (distance) .

In this question:  Work = (25 N) x (6 m) = 160 joules .
_____________________________

The formula for potential energy is

                   PE  = (mass) x (gravity) x (height) .

On Earth, gravity = 9.8 m/s² 

This information gives you both of the other questions.

#2).  PE  = (mass) x (gravity) x (height)

               = (5 kg) x (9.8 m/s²) x (3m) =  147 joules

#3).  PE  = (mass) x (gravity) x (height)

               = (10 kg) x (9.8 m/s²) x (20 m) =  1,960 joules

A light bulb converts electrical energy into light energy and also some thermal energy. The amount of electrical energy is 50 Joules before the conversions. What is the total amount of energy from before the conversions to after the conversions?

Answers

If the amount of electrical energy is 50 Joules before the conversions, then it would be 50 Joules after the conversion.

According to law of conservation of energy, we cannot create or destroy energy so it remains constant
