Answer:
B. 1520 N
Explanation:
The weight of each object can be calculated by using the formula:
where m is the mass of the object and g the acceleration due to gravity.
- The mass of the cow is m = 410 kg, so its weight is
- The mass of the car is m = 565 kg, so its weight is
So, the difference in weight is
And the closest answer is
B. 1520 N
Answer:
True
Explanation:
It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. Any change in motion involves an acceleration, and then Newton's Second Law applies.
- Hyperphysics
Answer:
18 grams
Explanation:
The mass of an object is the object's fundamental property. It is the amount or quantity of mater in the object. Irrespective of the object's location or the gravitational force applied on the object, the mass of an object remains the same. In other words, the mass of an object is the same everywhere.
The mass should however not be confused with its weight which depends on the mass and the gravitational force applied on it.
In summary, whether on earth or in the moon, the mass of an object remains the same. If the mass of the object is 18 grams on earth, it will also be 18 grams in the moon.
1. Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
2. Insulation helps to prevent that transfer of heat. Many different materials are used for insulation. Engineers often use fiberglass, wool, cotton, paper (wood cellulose), straw and various types of foams to insulate buildings. A layer of trapped air can serve as insulation, too!
3. I'm not sure. Sorry
