Answer with Explanation:
We are given that
Power of toaster=
Power of electric frying pan=
Power of lamp=
Current in circuit=15 A
Potential difference= V=120 V
We know that
Current=
Using the formula
Current drawn by toaster=
Current drawn by electric frying pan=
Current drawn by lamp=
Answer:
Option B
3
Explanation:
The two dimensions have the following significant numbers
4.56- 3 significant numbers
5.668- 4 significant figures
When responding, we give area as per the most precise number given hence the smallest (most precise) significant figures in these two numbers is 3. Therefore, the area will be given to 3 significant figures ie
4.56*5.668=25.84608 square meters
Area=25.8 square meters
Answer:
An atom is the smallest unit of ordinary matter that forms a chemical element.
Matter is composed of very tiny or microscopic particles called "Atom".
(According to Dalton atomic theory some of his principles were wrong and later was corrected but the definition of an atom was right in his theory).
Answer:
Part a)
First image
second image
Part b)
First image
Second image
Explanation:
When object is placed between mirror and convex mirror
then for the first image
now from the mirror formula
here we have
For second position of image we will take object for convex mirror to be the position of image formed in plane mirror
so the distance of that image from convex mirror is
now by mirror formula
Part b)
Height of image and height of object is related by the equation
for height of second image
I think the correct answer is a series circuit. This type of circuit is characterized by having only one path for electric current to flow. All of the components in the circuit share the same current. Hope this answers the question. Have a nice day.
