Which object has the most thermal energy?
A. A 6 kg rock at 15°C
B. A 6 kg rock at 10°C
C. A 10 kg rock at 10°C
D. A 10 kg rock at 15°C
Answer:
D. A 10 kg rock at 15°C
Explanation:
Thermal energy is heat energy, meaning that the hotter rocks will have more energy.
The heavier/larger rocks can store more energy.
So if we combine the largest two variables, we get a 10kg rock at 15°C.
Answer: D

Why is it important to describe motion in universal terms?
Answer:
Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.
Explanation:
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.
The motion of an object occurs when there is change in the position of the object with time and the object moves in the direction of the applied force. This motion is influenced by the net force acting on the object.
For example:
The dimension of speed of object in motion is measured with two fundamental quantities (length and time);
speed = LT⁻¹
The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

A car accelerates at 3 m/s*2. Assuming the car starts from rest, how much time does it need to
accelerate to a speed of 12 m/s?
3 sec
2 sec
4 sec
12 sec
None of the other answers
Acceleration,a = 3 m/s²
Initial velocity,u = 0 m/s
Final velocity,v = 12 m/s
To be calculated:-Calculate the time take by a car.
Solution:-According to the first equation of motion:
v = u + at
★ Substituting the values in the above formula,we get:
⇒ 12 = 0 + 3 × t
⇒ 12 = 3t
⇒ 3t = 12
⇒ t = 12/3
⇒ t = 4 sec
We are given with some parameters used in Kinematics for determining the motion of an object.
Accleration = 3 m/s²Started from rest (Initial vel.) = 0 m/sFinal velocity = 12 m/sWe have to find the time taken by the car to attain the final velocity with the given accleration. By using 1st equation of motion which says:
v = u + atFinal velocity = Initial velocity + Accl. × Time taken
Plugging the values,
➝ 12 = 0 + 3(t)
➝ 3t = 12
➝ t = 4 s
So, the correct answer is Option C. And we are done...

What is the momentum of A 200 kg shark swimming at 15 m/s
Answer:
3000 kg meter per sec
Explanation:
Momentum of an object refers the motion of an object. Momentum depends upon mass and velocity both.
Formula to calculate the momentum of any object is,
Momentum = Mass × Velocity
By substituting values of mass and velocity of the shark from the question,
Momentum of shark = 200 × 15
= 3000 kg meter per second
Therefore, shark weighing 200 kg has the momentum as 3000 kg meter per seconds.

Steve is recording the temperature of an object on Celsius and Fahrenheit scales. Relationship between the two scales is given by F = 1.8 ⋅ C. Steve will plot the Celsius readings along the y-axis and the Fahrenheit readings along the x-axis. (5 points) True False
Answer:
False
Explanation:
since the Farenheit depends on the amount of Celsius times (*) 1.8 (F= 1.8 * C),
then we can deduce that Farenheit is the dependent variable while celsius is independent. after this, remember that the independent variable is the X value and the dependent variable is the Y value.

What is chemical reaction?A chemical reaction is a procedure that causes one group of chemical components to change chemically into another.
Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei (no change to the elements present).
The study of chemical processes involving unstable and radioactive elements, where both electronic and nuclear changes may take place, is known as nuclear chemistry.
