INPUT ARTICLE: Article: The force (F) required to move an object of mass (m) with an acceleration (a) is given by the formula F = m x a. So, force = mass multiplied by acceleration. The International System of Units (SI) unit of mass is the kilogram, and the SI unit of acceleration is m/s2 (meters per second squared). So when mass and acceleration are expressed in their SI units, we get the force in its SI units which is N (Newtons) As an example, if the mass of the object is given to be 3 pounds, you'll need to convert those pounds to kilograms. 3 pounds make 1.36 kg, so the mass of the object is 1.36 kg. If the weight of an object is given in N (Newtons), then divide it by 9.8 to get the equivalent mass. For example, 10 N weight is equivalent to 10/9.8 = 1.02 kg.

SUMMARY: Multiply mass times acceleration. Convert figures to their SI values. Keep in mind that weight and mass mean different things in Physics.

In one sentence, describe what the following article is about: To clean the tank, you first need to place your crab in a holding container so you can give the tank and the accessories a good clean. The container can be a clean plastic tub or bin. Your crab will likely run around the holding container while you clean his tank. You can leave a small bowl of dechlorinated water out and place it next to the holding container so it comes to room temperature. You can then use this bowl later to clean any mites on your pet so he is mite free when he goes back into his clean, mite free tank. If you'd really like to make sure there are no mites left in the tank at all, you can use a small vacuum to suck out any mites in the tank. Do this before you wet the tank, as the vacuum will work better on a dry surface. Focus on the corners of the tank as this is where the mites tend to like to hang out. Once you have removed the accessories, you can wipe down the tank with a wet paper towel. Press down on the sides and bottom the tank to swish any mites and remove them. Make sure you do this in the corners of the tank, as this is often where the mites like to hide. You can also rinse the tank out with tap water to drown and wash away any mites still in the tank. Try to eliminate any black flecks in the tank so the tank is spotless and clean. Mites do not like direct sunlight, so once you rinse and wipe down the tank with plain water, you should let it dry completely in the sun. You can also let the tank dry indoors overnight. Once the tank is dry, you can place the sterilized tank accessories back into the tank.
Summary: Place your crab in a holding container. Use a small vacuum to remove the mites in the tank. Wipe down the tank with plain water to remove any mites still in the tank. Let the tank dry in direct sunlight.

INPUT ARTICLE: Article: Remove excess food and waste and spot-clean the cage as needed with a wet paper towel. Scoop out any soiled bedding and replace it with dry, fresh bedding. This should be done every single day. If your guinea pig spills water into the food dish, remove that food and replenish the dish with fresh, dry food. Doing this every day will help prevent bacteria from growing in the food and water receptacles.

SUMMARY:
Spot-clean the cage. Refill food and water. Wash food and water dishes in hot, soapy water.
