what type of energy results from the burning of wood or gasoline?
Answer:
Chemical energy
Explanation:
Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. Chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine.
A ship travels north at 15 km/h for 2 h. What is the ship's displacement in km?
The ship travels with a velocity of 15 km/h within 2 hours. The distance travelled is the velocity times the time taken that is 30 km to the north.
What is velocity ?Velocity is a physical quantity measuring the distance travelled by an object per unit time. Velocity is the rate of speed and it is a vector quantity having both magnitude and direction. The unit of velocity can be m/s, km/h, ft/s etc.
Velocity is the ratio of the change in distance to the change in time. The change in distance is sometimes called the displacement.
then velocity = displacement / time
Given that velocity = 15 km/h
time taken = 2 hours
then displacement = velocity × time
= 15 × 2 = 30 Km
Therefore, the displacement of the ship is 30 km to the north.

A force of 36 N pushes a box that is 12.2 kg. The box is sliding horizontally 2.6 m/s to the left. What is the coefficient of friction? (Could you draw a Force Diagram?)
The coefficient of friction on the box sliding to the left is 0.3.
The given parameters;
applied force , F = 36 Nmass of the box, m = 12.2 kgvelocity of the box, v = 2.6 m/sThe acceleration of the box is calculated as follows;
[tex]F = ma\\\\a = \frac{36}{12.2} \\\\a = 2.95 \ m/s^2[/tex]
The coefficient of friction on the box is calculated as follows;
[tex]\mu_k = \frac{a}{g} \\\\\mu_k = \frac{2.95}{9.8} \\\\\mu_k = 0.3[/tex]
Thus, the coefficient of friction on the box is 0.3.

Freud was an influential and controversial psychologist who believed that psychology should study the unconscious mind. Describe
the two books Freud published in the early 1900s. (Site 2)
Answer:
The Interpretation of Dreams": Freud noticed that dreams played an important role in his analysis of neurotic and "hysterical" patients. When he asked his patients to talk about whatever came into their minds, they often referred to their dreams, which would set off other associations and often illuminate other important connections in their past experience. It took Freud about two years to write the book, finishing it in September 1897.

how many electrons does boron have
Answer:
5 Electrons
Explanation:
Boron has 5 protons, 5 neutrons and 5 electrons. The atomic number (also known as the proton number) of Boron is 5 as it has 5 protons. It has a mass number of 10, as protons and neutron have a relative atomic mass of 1 each, and a neutral charge, as there are equal numbers of +1 protons and −1 electrons.

Which situations might cause two observers (A and B) to measure different frequencies for the same vibrating object? Select the two correct answers.
A. Observer A is stationary and Observer B is moving.
B. Observer A and Observer B are moving at different speeds relative to each other.
C. Observer A and Observer B are stationary but at different distances from the vibrating object.
D. Observer A and Observer B are both stationary and at the same distance from the object.
Answer: The answer is (B) Observer A and Observer B are moving at different speeds relative to each other. And (A) Observer A is stationary and Observer B is moving
Explanation:
This question involves the concept of doppler's effect and its effect on the frequency of sound.
The situations that might cause the two observers to measure different frequencies for the same vibrating object are:
"A. Observer A is stationary and Observer B is moving.
B. Observer A and Observer B are moving at different speeds relative to each other."
Doppler's effect states that the apparent frequency of a source of sound is different than its original frequency. It further explains that whenever an observer and the source are in relative motion with each other, either the source or the observer or both are moving, then the frequency of sound measured by the observer will be different than the actual frequency. This changed frequency is called the apparent frequency and it depends upon the direction and magnitude of the relative motion of the observer and the source.
Hence, the measured frequency can be different for the two observers if they are in relative motion with the source, with different speeds, or in the case when one observer is stationary while the other is in motion.
Therefore, the situations that might cause the two observers to measure different frequencies for the same vibrating object are:
A. Observer A is stationary and Observer B is moving.
B. Observer A and Observer B are moving at different speeds relative to each other.

How do interaction forces act on different masses and on different objects?
Dosen't make sense
Explanation:
TRUE - Two colliding objects will exert equal forces upon each other. If the objects have different masses, then these equal forces will produce different accelerations. ... FALSE - In any collision, the colliding objects exert equal and opposite forces upon each other as the result of the collision interaction.

Why is air pressure lower on top of the airplane wing?
Answer:
Explanation:
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing.
