Question

What is the weight of the object in mass of 50kg on earth and on the moon?

Answer 1

Answer:

Explanation:

The weight of an object on the moon is 1/6th of that of its weight on earth. So, the weight of an object of mass 50 kg would be 500 N (taking g = 10 m/s) and on the moon would be 83.3 N (500-: 6). So, the weight would always be less on the moon.

hope this helps ya'! pls mark me as brainliest! :))

Answer 2

Answer:

Explanation:

heating coil is to be made, from nichrome wire, which will operate on a 12 V supply and will have a power of 36 W when immersed in water at 373 K. The wire available has a cross-sectional area of 0.10 mm². What length of wire will be required? (Resistivity of nichrome at 273 K = 1.08 x 10-6 Ωm. Temperature co-efficient of resistivity of nichrome = 8.0 x 10-5 K-1.)
