Answer:
when an acount is made online i can also give you the other awnsers
Explanation:
F = ma (force = mass x acceleration)
So the car’s mass affects the amount of force, changing how it would roll down a ramp, I think.
Explanation:
potential difference = current × risstance
see part a point3 current is same
v= IR
v = 8×0.2
v= 1.6
see part a point 5
this potential difference is less than cell
Answer:
force exerted by the cat is 693 N
Explanation:
We know that total energy is the sum of work done by gravity and friction i.e.
solving for F
here -ve sign indicate work done in opposite direction
where, m is mass of cat = 4.00 kg
h = 2.00 m,
Putting all value in above equation
F = 692.53 N = 693 N
Therefore force exerted by the cat is 693 N
