Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules. That's it.
Answer:
The resistance of the internal light bulb of the car is higher than that of the household circuitry.
Explanation:
Given the following data;
I. Current = 1.5 A
Voltage = 12 V
To find the resistance;
Voltage = current * resistance
12 = 1.5 * resistance
Resistance = 12/1.5
Resistance = 8 Ohms
II. Power = 100 Watt
Voltage = 110 V
To find the resistance;
Power = voltage/resistance²
100 = 110/resistance²
Cross-multiplying, we have;
100resistance² = 110
R² = 110/100
R² = 1.1
Taking the square root of both sides, we have;
R = √1.1
R = 1.05 Ohms
Therefore, the resistance of the internal light bulb of the car is higher than that of the household circuitry.
Answer:
New gravitational force, F' = 216 units
Explanation:
Given that,
Gravitational force between object 1 and 2, F = 72 N
The gravitational force between two objects is given by :

............(1)
If the mass of object 1, 

If the distance between objects is halved, 
Let new gravitational force is F'. It is changed to :





F' = 216 units
So, the new gravitational force will be 216 units.
is this the skater one? If so, it does support the law of conservation of energy because at the top of the ramp the skater has the same amount of potential energy their total energy and as the skater goes down the ramp their potential energy lowers as their kinetic energy rises.
