1.	The value of 120 joule per second on a system thathas 10 g, 10^2 cm and 10^3 second as base unit is ____(1) 12 x 10^10 units (2) 12 x 10^12 units(3) 12 x 10^14 units (4) 12 x 10^16 units
Answer» here we are USING the basic formula for unit conversion through dimensional analysis any physical QUANTITY is equal to the product of its unit with the magnitude if you have a physical quantity X then X = n1u1 = n2u2 where YUVAN YouTube or units of the physical quantity in two different systems and n1and n2 are magnitudes corresponding to two different systems n2 = n1u1/u2 = 120(1kg/10g)(1m/10²cm)²(1s/10³s)-³ =120(10²)(1)²(10-³)-³ =12×10¹² answer is (2) Any doubts ask me through chat

Answer»

here we are USING the basic formula for unit conversion through dimensional analysis

any physical QUANTITY is equal to the product of its unit with the magnitude

if you have a physical quantity X then

X = n1u1 = n2u2

where YUVAN YouTube or units of the physical quantity in two different systems and n1and n2 are magnitudes corresponding to two different systems

n2 = n1u1/u2

= 120(1kg/10g)(1m/10²cm)²(1s/10³s)-³

=120(10²)(1)²(10-³)-³

=12×10¹²

answer is (2)

Any doubts ask me through chat
