Physics
1 answer:
CaHeK987 [17]3 years ago
4 0

Answer:

The effect of gravity extends from each object out into space in all directions, and for an infinite distance. However, the strength of the gravitational force reduces quickly with distance. Humans are never aware of the Sun's gravity pulling them because the pull is so small at the distance between the Earth and Sun.

sasho [114]

Answer:

The height of the tower is 8.96 m.

Explanation:

We have, a visitor to a lighthouse wishes to determine the height of the tower. She ties a spool of thread to a small rock to make a simple pendulum, which she hangs down the center of a spiral staircase of the tower. The period of oscillation is 6.01 s.

It is required to find the height of the tower. Let it is l. The time period of a simple pendulum is given by :

T=2\pi \sqrt{\dfrac{l}{g}}

l is length of pendulum, or height of tower

l=\dfrac{T^2g}{4\pi^2}\\\\l=\dfrac{(6.01)^2\times 9.8}{4\pi^2}\\\\l=8.96\ m

So, the height of the tower is 8.96 m.

Answer:

Fix any holes or cracks in your walls. Inspect your walls and pay close attention to the areas around window frames, ventilation grates, and electrical sockets. If you find any holes or cracks, repair them with caulk. If the damage is substantial, reach out to a professional to handle drywall or plaster cracks and holes.

Seal your doors. Installing weathering strips to your door frames not only helps to stop heat loss but can also help to hamper noise traveling throughout your home.

Replace your internal doors. If the doors inside your home are hollow, you may consider replacing them with solid doors. This will reduce the amount of sound which is able to pass through. You could try fitting it yourself but for truly great results you better reach out to professionals.

Replace or repair your windows. This is an expensive option, depending on how many windows you replace. However, upgrading your windows to double or triple-paned with PVC frames can dramatically reduce noise pollution. If you prefer natural materials, having your wooden windows and frames repaired can also help reduce the clamour and racket coming from outside.

Fix squeaky floors. Hardwood floorslook great and can add a lot of character to a room, but if one or more of the floorboards are loose, it can cause a never-ending squeaky nightmare. Although a fresh installation would be great, to get your flooring back in shape with trusty specialists is the best.

Insulate your walls and ceiling. Installing insulation product, such as ceiling panels, mass-loaded-vinyl, neoprene rubber, viscoelastic foam, and fibreglass behind walls and ceiling panels can drastically lessen the amount of noise coming in, or out, of your home.

Explanation:

Make use of big, thick rugs. If you cannot bear to cover your hardwood floors, the next best option for blocking some of the noise from below is to use rugs. The right rug can really tie a room together, as well as provide a soft, warm refuge for your feet.

Consider putting up heavy curtains. Changing your curtains for an alternative made from a heavier material can absorb a surprising amount of noise from the street. To block even more noise, make sure that your curtains also cover the wall below and above the windows. For a fantastic job, consider our fantastic curtain fitting service.

Rearrange your furniture. You can block some of the noise from the next door neighbours by arranging your furniture so that larger pieces are placed against the shared wall.

Build and fill a large bookcase. This one is especially aimed at book lovers. You can pick bespoke furniture or flat pack assembly. By filling the bookcase and ensuring there isn’t a lot of empty space on the shelves, you will find that a good amount of noise from the outside, or your neighbours, is unable to make its way into the room as books are excellent at absorbing noise. If you are a passionate book lover, read our blog on how to make the perfect reading nook.
