A cylinder has a height of 6 millimeters and a radius of 4 millimeters. What is its volume? Use ≈ 3.14 and round your answer t

netineya [11]

Answer:

$V=301.44\ \text{mm}^2$

Step-by-step explanation:

Given that,

Height of the cylinder, h = 6 mm

Radius of the cylinder, r = 4 mm

We need to find the volume of the cylinder. The formula for the radius of the cylinder is given by :

$V=\pi r^2 h$

Putting given values,

$V=3.14\times (4)^2 \times 6\\\\V=301.44\ \text{mm}^2$

So, the volume of the cylinder is $301.44\ \text{mm}^2$ .

If a 2-kg block compresses a spring 800mm from its relaxed state, how much potential energy does the block have due to the sprin

Tju [1.3M]

Answer:

8 Joule

Step-by-step explanation:

Mass of block = 2 kg

Displacement = x = 800 mm = 0.8 m

Spring constant = k = 25 N/m

Potential Energy of a spring

Work done = Difference in Potential Energy

Work Done = Δ P.E.

$\Rightarrow \Delta\ P.E.=\frac{1}{2}kx^2$

⇒P.E. = 0.5×25×0.8²

⇒P.E. = 8 Nm = 8 Joule

Here already the spring constant and displacement is given so the mass will not be used while calculating the potential energy.
