A driver in a Volkswagen bug (mass = 1335 kg) pulls out going 10 miles per hour in front of a Ford pickup truck (mass = 2675 kg) which is traveling 40 miles per hour. The two vehicles experience a head-on collision. Which of the following statements is true concerning the forces that each vehicle (and driver) experience in this collision? a. The Volkswagen bug experiences a much greater force than the Ford pickup truck due to the greater speed of the truck.
b. The Volkswagen bug experiences a much greater force than the Ford pickup truck due to the larger mass of the truck.
c. The Volkswagen bug experiences a force that is the same as the Ford pickup truck experiences.
d. The Volkswagen bug experiences a much smaller force than the Ford pickup truck due to the smaller speed of the Volkswagen bug.
e. The Volkswagen bug experiences a much smaller force than the Ford pickup truck due to the smaller mass of the Volkswagen bug

Answers

Answer 1

Answer:

Answer:C

Explanation:

Given

mass of Volkswagen $m_1=1335 kg$

speed of Volkswagen $v_1=10 mi/hr$

mass of Ford pick up $m_2=2675 kg$

speed of ford pick up $v_2=40 mi/hr$

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 2

Answer:

Answer:

c. The Volkswagen bug experiences a force that is the same as the Ford pickup truck experiences.

Explanation:

Given:

mass of Volkswagen bug, $m_v=1335\ kg$

speed of Volkswagen bug, $v_v=10\ mi.hr^(-1)$

mass of Ford pickup, $m_f=2675\ kg$

speed of Ford pickup, $v_f=40\ mi.hr^(-1)$

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.

Answers

When the switch is open, the ammeter reads zero. When the switch is closed, the meter reads a number that's (battery voltage) divided by (resistance of the lamp), and the lamp glows.

the ammeter would read the current flowing in the circuit

A block of metal initially at 25°C is submerged in water initially at 75°C in a coffee cup. Which of the following is true? a. The final temperature of the coffee cup will be less than 20°C.
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.

Answers

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 $75^0C$ and $25^0C$ to have thermal equilibrium.

When Ava first opened her beverage, there were lots of bubbles. However, as her drink got warmer, she noticed that there were fewer bubbles in it. In general, as the temperature increases, the solubility of solids _______ while the solubility of gases _______. 1) increases, decreases 2) increases, increases 3) decreases, decreases 4) decreases, increases

Answers

In general, as the temperature increases, the solubility of solids increases, while the solubility of gases decreases. Therefore, the correct answer is 1) increases, decreases.

Final answer:

Generally, as temperature rises, solid solubility increases while gas solubility decreases. This is why when a carbonated drink gets warm, it has less bubbles.

Explanation:

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.

The Pangaea theory supports the theory of plate tectonics because _____.it is based on the idea that there were several land masses when Earth was first created
it is based on the idea that all the present continents were one supercontinent
it does not require scientists to support the notion that Earth's plates can move
one day, Earth will have one large land mass again

Answers

The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent.
