Yes
Explanation:
One can pick up a nail using the curved part of the horseshoe magnet farthest from the poles.
A horse shoe magnet has magnetic fields all around it.
- In the presence of magnetic force fields, any magnetic object will be attracted to it.
- This is the case with any magnet.
- A magnet is any object with magnetic fields all around it.
- This field causes attraction to any magnetic objects especially metals.

Answer:
5.77×10¹⁰ m
Explanation:
From the question,
Applying
Kepler's third law
P² = d³...................... Equation 1
Where P = Planet's period, d = distance between the center of the planet and the sun.
make d the subject of the formula n equation 1
d = ![\sqrt[3]{P^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7BP%5E%7B2%7D%20%20%7D)
.................. Equation 2
Given: P = 0.24 sidereal.
Substitute the value of P into equation 2
d = ![\sqrt[3]{0.24^{2} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B0.24%5E%7B2%7D%20%7D)
d = 0.386 Au
d = 0.386×1.496×10¹¹
d = 5.77×10¹⁰ m
Directly most of alternative energy is gained from water. But eventually almost all energy on earth comes from sun. Without sun we wouldn't have rivers (no rains), we wouldn't have wind (let alone oil or coal) etc. We would only have geothermal and seismic power.
Direct sun radiation conversion (via collectors or photovoltaic) is not very popular yet. But indirectly sun is the main source of earths energy.
Answer:
0.41
Explanation:
A 49 N block has a mass of 5 kg:
49/9.8
A horizontal force of 50 N giving it an acceleration of 6 m/s^2 means that 30 N is taken up by the acceleration
This leaves 20 N to take care for friction. so the coefficient of friction is:
20/49 = 0.41.
Answer: Option (B) is the correct answer.
Explanation:
When model B shows three dimensional shape of the molecule then it becomes easier to visualize the exact shape or geometry of the molecule as we get to know how atoms are bonded together.
Therefore, with the help of this it would be easy to know the hybridization of molecule. Basically, we will get to know the type of molecule represented by model B.
Thus, we can conclude that the statement Model B shows the three-dimensional shape of the molecule, but Model A does not represents Model B better than Model A.
