A 1.5-kg block slides at rest starts sliding down a snow-covered hill Point A, which has an altitude of 10 m. There is no fricti

damaskus [11]

Answer:

the speed of the block when it reaches point B is 14 m/s

Explanation:

Given that:

mass of the block slides = 1.5 - kg

height = 10 m

Force constant = 200 N/m

distance of rough surface patch = 20 m

coefficient of kinetic friction = 0.15

In order to determine the speed of the block when it reaches point B.

We consider the equation for the energy conservation in the system which can be represented by:

$\dfrac{1}{2}mv^2=mgh$

$\dfrac{1}{2}v^2=gh$

$v^2=2 \times g \times h$

$v^2=2 \times 9.8 \times 10$

$v=\sqrt{2 \times 9.8 \times 10$

$v=\sqrt{196$

v = 14 m/s

Thus; the speed of the block when it reaches point B is 14 m/s

What happens when the wire in an electromagnet is wrapped around a soft iron core?

Pavlova-9 [17]

The magnetic particles in a soft iron nail will line up with the magnetic field when the current is switched on. ... When you switch on the current, the coil becomes an electromagnet. But also, the soft iron core becomes a magnet. It will add to the strength of the electromagnet.

A wooden block has a mass of 986 g and a density of 16 g/ cm3. What is the volume?

netineya [11]

Density = Mass / Volume.
Volume = Mass / Density = 986 / 16 = 61.625 cm^3.
