4)What is the mass of an object weighing
3,000N?

Explanation:

306.12 Kg,

The mass of an object weighing 3000N is 300kg

Explanation:

Here,

Weight (W) = 3000N is given

So,

we will use

W = mg

where,

m = mass of the body

g = acceleration due to gravity

Now,

W = mg

3000 = m × 10

m = 3000 ÷ 10

m = 300kg

Thus, The mass of an object weighing 3000N is 300kg

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
