Why does it take more force to get a resting object to move than it does to keep

Physics

Triss [41]3 years ago

Answer:

Objects have a natural tendency to resist change. ... Heavier objects (greater mass) resist change more than lighter objects. Example: Pushing a bicycle or a Cadillac, or stopping them once moving. The more massive the object (more inertia) the harder it is to start or stop.

A cell has an internal resistance of 0.02ohms and e.m.f of 2.0v calculate it's terminal p.d if it's delivers (a)5A ( b)50A

Aleksandr-060686 [28]

Answer:

(a) The terminal voltage of the cell is 1.9 V.

(b) The terminal voltage of the cell is 1.0 V.

Explanation:

Given:

(a)

E.M.F of the cell (E) = 2.0 V

Internal resistance of the cell (r) = 0.02 ohms

Current passing through the cell (I) = 5 A

Now, the potential difference across the terminals of the cell is given as:

$V=E-Ir$

Plug in the given values and solve for 'V'. This gives,

$V=2.0-(5\times 0.02)\\\\V=2.0-0.1=1.9\ V$

Therefore, the terminal voltage of the cell is 1.9 V.

(b)

E.M.F of the cell (E) = 2.0 V

Internal resistance of the cell (r) = 0.02 ohms

Current passing through the cell (I) = 50 A

Now, the potential difference across the terminals of the cell is given as:

$V=E-Ir$

Plug in the given values and solve for 'V'. This gives,

$V=2.0-(50\times 0.02)\\\\V=2.0-1.0=1.0\ V$

Therefore, the terminal voltage of the cell is 1.0 V.

Calculate the total resistance for a 650ohm , a 350 ohm , and a 1000 ohm resistor connected in series

Mekhanik [1.2K]

Answer:

2000 ohms

Explanation:

Resisters in series just add.

Rt = R1 + R2 + R3

R1 = 650 ohm

R2 = 350 ohm

R3 = 1000 ohm

Rt = 650 + 350 + 1000

Rt = 2000 ohms.
