Answer:
- one battery
- two switches
- two resistors
- three light bulbs
Explanation:
Matching the description to the symbols shown below, we make the following correlations:
- circle with an X = light bulb; 3 are described
- small circle connected to another small circle = switch; 2 are described
- stack of horizontal lines (longer/shorter) = battery; 1 is described
- zigzag = resistor; 2 are described
Apparently, the diagram has 1 battery, 2 switches, 3 light bulbs, and 2 resistors.
Answer:
The molecules absorb heat and acquire more kinetic energy.
Explanation:
In a solid, the solids only vibrate about their mean positions but do not translate. When energy is supplied to the molecule in the form of heat, the molecules vibrate faster. Eventually, they acquire sufficient energy to leave their mean positions and translate. Hence the solid crystal collapses.
When ice is heated, water molecules acquire sufficient kinetic energy to translate. The intermolecular bonds are gradually broken in the solid framework as heat is absorbed. The heat required for this is known as the latent heat of fusion.
The temperature remains constant until phase transition is over, then temperature rise resumes.
Answer:
Apples weigh more due to the larger mass, yet same quantity. With a 1050% increase over an average grape. Multiply 150g x 7g = 15000, bow multiply 7g x 100g = 700. Both equal
Explanation:
Your average apple weighs about 150g and 250g. The average grape weighs about 7g being small, and a large 11g. That's a 1050% increase.. Disclaimer I haven't measured massxweightxheight in awhile so might be completely wrong Mass is a measure of how much force it will take to chanfe the path
