Answer:
When mass is greater, the force needed must be greater keeping the acceleration of the wheel chair constant
Explanation:

force is directly proportional to the mass
The answer is B. The less massive object to orbit the more massive object.
Explanation: The more massive the object, the larger its gravitational pull.
Example: the moon orbits the earth because the moon’s mass is smaller than earth, earth orbits the sun because the earth’s mass is smaller than the sun..
Explanation:
Start with what you know and list your knowns and unknowns
F = ma
F= 3N
m = 6kg
a =?
3N = 6kg x a
solve for a
3N / 6kg = a
Answer: Gravitational force
Explanation:
A non contact force can be described as a force applied to an object by another body that is not in direct contact with it.
For example, an object thrown upwards will return back due to the force of gravity acting on it. So, it means Gravitational force is acting on the body without necessarily being in contact with that body.
Answer:
a

b

Explanation:
From the question we are told that
The current is 
The length of one side of the square 
The separation between the plate is 
Generally electric flux is mathematically represented as

differentiating both sides with respect to t is

=> 
Here
is the permitivity of free space with value

=> 
=> 
Generally the displacement current between the plates in A

=>
