Answer 1

Answer:

[tex]\bf\pink{(C)\:12000\:J}[/tex]

Explanation:

Given :-

[tex]\sf\red{Mass = 200 \ kg}[/tex][tex]\sf\orange{Gravity = 10 \ m/s}[/tex][tex]\sf\green{Height = 6 \ m}[/tex]

Need to find :-

[tex]\sf\blue{Work \ done}[/tex]

Formula required :-

[tex]\sf\purple{Work \ done = Mass \times Gravity \times Height}[/tex]

Solution :-

[tex]\to\:\:\sf\red{Work \ done = Mass \times Gravity \times Height}[/tex]

[tex]\to\:\:\sf\orange{Work \ done = 200 \times 10 \times 6}[/tex]

[tex]\to\:\:\sf\green{Work \ done = 2000 \times 6}[/tex]

[tex]\to \:\ \sf\blue{ Work \ done = {\bf{\blue{1200\:J}}}}[/tex]

Hence, [tex]\bf\green{(B)}[/tex] is the correct option.

3 A, calculate the size of the resistor

Answers

Answer:

4 Ohms

Explanation:

Apply the formula:

Voltage = I (current) . Resistance

You can change it the way you want to use for your purpose.

In this case...

R = V/I

R = 12/3

R = 4 Ohms (Ohm is the unit of measurement of eletrical resistance)
