The positive plate is made of lead grid with a lead oxide paste coating and the negative plate is porous lead. Dilute sulphuric acid is the electrolyte. The lead acid battery produced a direct current or DC during a chemical reaction that turns lead dioxide to lead sulphate and sulphuric acid to water.

A sled is being pulled along a horizontal surface by a horizontal force F of magnitude 600 N. Starting from rest, the sled speed
Simora [160]

Answer:

1440 W

Explanation:

First of all, we can find the total displacement of the sled, which is given by

d=\frac{1}{2}at^2

where

a = 0.08 m/s^2 is the acceleration

t = 1 min = 60 s is the time

Substituting,

d=\frac{1}{2}(0.08 m/s^2)(60 s)^2=144 m

Now we can find the wotk done on the sled, equal to the product between force and displacement:

W=Fd=(600 N)(144 m)=86,400 J

And finally we can fidn the average power, which is the ratio between the work done and the time taken:

P=\frac{W}{t}=\frac{86,400 J}{60 s}=1440 W

Choose the correct statement below about the interaction between magnets, magnetic materials and charges.
bekas [8.4K]

Answer: B. The south magnetic pole attracts the north pole of another magnet.

Explanation:

The correct statement below about the interaction between magnets, magnetic materials and charges is that the south magnetic pole attracts the north pole of another magnet.

We should note that a magnet typically consists of two poles which are the North Pole and the South pole. The opposite poles doesn't repel each other but attracts each other while same pole repels one another.

In this case, the North Pole will attract the South Pole while same magnetic piles repel e.g the North Pole will repel the North Pole.

What is formed from nuclear decay?
Digiron [165]

Answer:

Energy and another nucleus of the new element/particle.

Explanation:

A nuclear decay is an radioactive decay where the nucleus of an atom becomes unstable and loses energy through emitting radiations.For example, there is an alpha decay that release  an alpha particle called helium-4, a beta decay that involve releasing a beta particle which normally occurs in a nucleus that has more neutrons than protons.Other decays are the gamma decay,electron capture and the spontaneous fission.Nuclear decay produces a lot of energy and radiations that could harm human cells if exposed.
