What is a magnet?
When electric charges move, a phenomenon known as magnetism is produced. These tiny movements can occasionally be found inside a material known as magnets. Magnets and the magnetic fields created by moving electric charges can attract or repel other magnets, which can also change how other charged particles move.
Because they can support a magnetic field that lasts forever, some materials, like iron, are categorized as permanent magnets. These are the magnets that are typically encountered in day-to-day life. Other materials like iron, cobalt, and nickel can be briefly given a magnetic field when placed inside a stronger, bigger magnetic field, but they will eventually lose their magnetic qualities.

D. 0.8000 m
Answers
Answer
C. 0.6125 m
Explanation
The magnification of an image produced by curved mirrors can be given in two ways;
Magnification, M = (Height of the image) / (height if the object) and
M = (image distance,V) / (Object distance, U).
Using the first formula,
M = 0.35/0.4
= 0.875
Now from the second formula,
M = V/U
0.875 = V/0.7
V = 0.875 × 0.7
= 0.6125 m
Answer : v = 0.1625 m.
Explanation :
It is given that,
Height of an object,
Object distance,
Height of an image,
We have to find the image distance (v).
We know that the magnification of mirror is the ratio of height of image to the height of object.
i.e. ..............(1)
Also, magnification is the ratio of image distance to that of object distance.
i.e ............(2)
So, from equation (1) and (2)
So, image is located at a distance of 0.6125 m.

The acceleration of gravity is inversely proportional to
the square of the distance from Earth's center.
The acceleration of gravity is 9.8 m/s² on the Earth's surface ...
6380 km from the center.
If the acceleration of gravity at 'h' is 4.9 m/s² ... 1/2 of what it is
on the surface, then the distance from the center is
(6380 x √2) = 9,023 km (rounded) ,
and 'h' is the distance above the surface
= (9,023 - 6,380) = 2,643 km (rounded) .

Correct answer choice is:
C. The filings will be clustered more densely where the field is weakest.
Explanation:
The closer mutually the field lines will be the more powerful the field would be present. The field is really powerful in the axis of the magnet, though as they are frequently accommodated in the magnet itself, the field is quite weak in the air close to the axis. As the field lines make rings, they have to penetrate in one spot and drop at different, the two poles must be extremely close mutually indeed in the air, and the field is consequently stronger. These points are the North and the south poles.

Explanation:
Total mass = 90 + 90 + 30 kg = 210 kg
Normal force = 210 kg ( 9.81 m/s^2) = 2060.1 N
Force of friction to overcome = normal force x coeff of static friction
F = 2060.1 x .15 = ~ 309 N to get the cart moving...
