Answer:C
Explanation:
Given
mass of Volkswagen
speed of Volkswagen
mass of Ford pick up
speed of ford pick up
When two bodies collide head-on then force experienced by both the bodies will be the same but opposite in direction.
According to newton's third law, the force exerted by one particle on another is equal to the force exerted by the second particle on first.
Thus two bodies will experience the same force
Answer:
c. The Volkswagen bug experiences a force that is the same as the Ford pickup truck experiences.
Explanation:
Given:
mass of Volkswagen bug,
speed of Volkswagen bug,
mass of Ford pickup,
speed of Ford pickup,
Since both undergo a head-on collision they both face the equal impact in accordance with the Newton's third law of motion which states that every action has equal and opposite reaction.
So the bug the force applied by the bug on the pickup is equal to the force applied by the pickup on the bug. This happens only till both the masses are in contact with each other.
b. The final temperature of the coffee cup will be higher than 25°C but less than 75°C.
c. The final temperature of the coffee cup will be more than 80°C.
d. The final temperature of the coffee cup will be 80°C.
Answer:
b. The final temperature of the coffee cup will be higher than 25°C but less than 75°C.
Explanation:
We know in thermal equilibrium.
Heat loss by one object = Heat gain by other object.
Now, heat is loss by the object whose temperature is higher than other because heat travels from high temperature to other.
And the object who gain heat its temperature increases till both body reach same temperature.
In this case, water loss heat, therefore its temperature decreases.
Similarly , metal block is at low temperature so its temperature increases.
Therefore , both water and metal block must have temperature less than and to have thermal equilibrium.
Generally, as temperature rises, solid solubility increases while gas solubility decreases. This is why when a carbonated drink gets warm, it has less bubbles.
Generally, as the temperature increases, the solubility of solids typically increases, while the solubility of gases usually decreases. Thus, for Ava's case with the beverage, as the drink got warmer (indicating an increase in temperature), the bubbles, which are gaseous, decreased. A real-life example of this is a carbonated drink. When you open a cold soda, it starts out very bubbly.
However, if you let it sit and warm up, the gas (carbon dioxide) becomes less soluble in the liquid and leaves the solution, resulting in fewer bubbles.
