the north end to the south end.

<h3><u>Explanation;</u></h3>

Magnetic field lines from a bar magnet form lines that are closed. The direction of magnetic field is taken to be outward from the North pole of the magnet and in to the South pole of the magnet.
A magnetic field refers to the area surrounding a magnet where a force is exerted on certain objects. These lines are spread out of the north end of the magnet.
The magnetic field lines resemble a bubble.

A sewing machine uses 1.6kWh of electricity in one day. If electricity costs 9p per unit, what is the total cost in pence of usi

atroni [7]

Answer:

$\huge\boxed{\sf 1.6\ units = 14.4p}$

Explanation:

Since,

So,

1.6 kWh = 1.6 units

If,

1.6 units = 9p × 1.6

1.6 units = 14.4p

Which of the following would have more momentum than fiona, a 313kg hippo, running at 8m/s?

kap26 [50]

Let's calculate the momentum of Fiona, given by the product between its mass and its speed:
$p=mv=(313 kg)(8 m/s)=2504 kg m/s$

Now let's compare it with the momentum of the other animals:
a) the mass of the sea turtle is missing, so we cannot calculate its momentum.
b) the momentum of the dolphin is
$p=mv=(150 kg)(18 m/s)=2700 kg m/s$
c) the momentum of the horse is
$p=mv=(380 kg)(4 m/s)=1520 kg m/s$
d) the momentum of the lion is
$p=mv=(190 kg)(11 m/s)=2090 m/s$

And we can see that the correct answer is b), because the momentum of the dolphin is greater than the momentum of Fiona.

Which is an example of an abiotic factor in a pound environment

zvonat [6]

A. The water

Biotic factors mean living this such as frogs, grasshoppers, snakes, etc.

Aboriginal factors means non-living such as water, temperature, sunlight, etc.
Abiotic factors are the non-living parts of the environment that have a major influence on living organisms which makes water an abiotic factor.

Hope this helped, if it did please like (if you want to :)
