<span>The difference between Dalton's model of the atom and Thomson's model was that Dalton's model had different elements that consist of different atoms and Thomson's model had atoms that have smaller particles called electron.

We're missing one essential piece of information that we need in order to answer this question. You have not specified <em>what planet</em> the object is falling on. The answer depends on the gravitational acceleration on that planet, and they're all different.
Without that information, we'll just go ahead and assume that the object is falling to the surface of the Earth. Wherever on Earth this tense drama is unfolding, the acceleration of gravity is going to be around <em>9.8 m/s²</em> everywhere.
So THAT's the object's acceleration if there is no air resistance. The object's MASS makes no difference. It doesn't matter whether the object is a sparrow feather or a school bus. Heavier objects DO NOT fall faster than light objects.
If there is no air resistance, then ALL objects fall with the same acceleration. It's called the "acceleration of gravity" on that planet or moon, and you can easily look it up. It's 9.8 m/s² on Earth, 1.62 m/s² on the Moon, 3.71 m/s² on Mars, 8.87 m/s² on Venus, and 24.8 m/s² on Jupiter.
Answer:
velocity of car=5.855 m/s
Explanation:
Answer:
C) at right angles to the direction of the motion
Explanation:
The magnetic force exerted on a charged moving particle is given by

where
q is the charge of the particle
v is the velocity of the particle
B is the magnetic field intensity
is the angle between the direction of v and B
Moreover, the direction of the force is perpendicular to both v and B. In particular, the direction can be found by using the right hand rule:
- index finger: direction of the velocity
- middle finger: direction of the magnetic field
- thumb: direction of the force (if the charge is positive, otherwise the direction must be reversed if the charge is negative)
