Answer:
M_Train>> m_car a_train <a_car
Explanation:
To start the movement of the train or the car, the motorcycle applies a force on the wheels, which starts the acceleration in the case of the train, it has a much greater mass than that of the car, for which to obtain the same acceleration necessary a much greater force
a = F / m
as the mass of the train is greater than that of the car.
a_train <a_car
Something similar happens when the vehicles stop, the engine stops applying force forward and the brakes apply a force backward that creates a negative acceleration that slows down, again as the mass of the train is much greater than the of the car its negative acceleration is much less.
It is good to clarify that to compensate for this the trains have a braking system on all wheels
That will depend on the coefficient of friction between the sliding surfaces, and also on Zak's weight. We don't have any of that information.

Answer:
physical material from which something is made or which has discrete existence
Explanation:
Answer:
The weight of body is 1.3040 gram.
Explanation:
Given that,
The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws.
Suppose a crab with a body weight of 1.8 gram has claws weighing 1.1 gram.
Estimate the weight of a fiddler crab with claws weighing 0.85 gram.
Determine the weight of crab body
We need to calculate the value of proportional constant
Put the value into the formula
We need to calculate the crab weight
Here, x = 0.85 g
Put the value into the formula
Hence, The weight of body is 1.3040 gram.
