The answer is D) Cyclones. I am 100% sure on this one, so yeah. Hope this helps, and good luck. :D
To solve this problem we will proceed to use Newton's second law for which the mass (m) multiplied by the acceleration (a) is defined as the Force (F) applied on a body, mathematically that is,

According to the statement for the first object, the acceleration is,

For the second object the acceleration is,

Solving for the mass of the second object,



Therefore the correct answer is D.
Answer:
Front weels
Explanation:
Because they are the one which select the direction of the car.
Answer:
The correct reaction force in response to Heidi's action force is:
c. The friction is equal to 660 N since the beam is not accelerating.
Explanation:
Heidi's action force does not affect the beam. Since friction resists the sliding or rolling of one solid object over another, there is no friction acting on the beam, in this respect. The reaction force is what makes the dog to move because it acts on it. According to Newton's Third Law of Motion, forces always come in action-reaction pairs. This Third Law states that for every action force, there is an equal and opposite reaction force. This means that the dog exerts some force on Heidi, as he pulls it "forward with a force of 9.55 N."
The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).
or C. Mass if you're on plato
