I used rise and run to see where point a lies .
That's kind of an answer you could you right?
Answer:
0.369 V
<u>Explanation:</u>
Given :
Capacitance ( c ) = 650 × 10–4 F
Charge ( q ) = 24 × 10–3 C
We are asked to find potential difference ( v )!
We know:
q = c v
= > v = q / c
Putting values here we get:
= > v = ( 24 × 10–3 ) / ( 650 × 10–4 ) V
= > v = 240 / 650 V
= > v = 24 / 65 V
= > v = 0.369 V
Therefore, potential difference between the plates is 0.369 V
The work done is 150 joules
Explanation:
Work occurs when a force (F) acts on an object to move it some
distance (d) from the start point
→ Work done = F × d
The S.I unit of work is Joule
A force of 50 N is used to move a footstool 3 m
→ F = 50 N
→ d = 3 m
→ Work done = F × d
Substitute the values of F and d in the rule
→ Work done = 50 × 3 = 150 joules
The work done is 150 joules

Answer:
A. The same amount
Explanation:
The acceleration at which objects free falls to the ground on Earth is constant and its value is always
, regardless of their mass (in this problem we neglect air resistance).
So, it doesn't matter if the two rocks are different or they are launched from different heights: their acceleration will be exactly the same.
This can be proved this way: first of all, the force of gravity exerted on every object is equal to the weight of the object,

where m is the mass of the object and g the acceleration of gravity.
However, we also know for Newton's second law that

where a is the acceleration of the object.
Combining the two equations,

So, the acceleration of an object in free fall is exactly the acceleration of gravity.
If the answer is not C D then is A bc of the way it crosses over
