<span>B.Water molecules will transfer heat as they move from the lower part of the bucket to the boat through all the condutions</span>
To calculate velocity, divide distance traveled by the time it took to travel that distance and add direction.
So either number 1 or number 3
The required energy to accelerate the golf ball is .
<h2>What is Energy?</h2>
- Energy, which is observable in the execution of labor as well as in the form of light and heat, is the quantitative quality that is transmitted to an object or to a physical phenomenon in physics.
- Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.
- The joule, which is defined as "the energy transmitted to an object by the effort of moving it a length of one metre against a force of one newton," is the standard measure for power in the International System of Units (SI).

Answer:
10 m/s²
Explanation:
Force is the product of mass of an object and its acceleration
The formula is : F= m*a -----where m is mass and a is acceleration
Use the values given in the equation as;
F= m*a
1000 = 100 * a
1000/100 = a
10 = a
10 m/s² = a
Answer:
The difference between the sound intensity is 13.98 dB.
Explanation:
Given that,
Distance from father = 30 cm
Distance from mother = 1.50 cm
We need to calculate the intensity
Using formula of intensity
For father,
....(I)
For mother,
....(II)
The difference between the sound intensity
Put the value into the formula
Hence, The difference between the sound intensity is 13.98 dB.
