When the wires are connected to the terminals of the battery, what causes electric current in the circuit?

1 answer:

4 0

Answer: The battery provides a voltage between terminals. The electric field set up in a wire connected to the battery terminals causes the current to flow, which occurs when the current has a complete conducting path from one terminal of the batter to the other. This is called a circuit.

Suppose the work required to stretch a spring from 1.1m beyond its natural length to a meters beyond its natural length is 5 J,

Nadya [2.5K]

Answer:

Explanation:

The formula for the work done on a spring is:

$W = \frac{1}{2}kx^{2}$

where k is the spring constant and x is the change in length of the string

For the first statement,

x = (a-1.1), W = 5

=> $5 = \frac{1}{2}k(a-1.1)^{2}$

Now making k the subject of formula, we have:

$k = \frac{10}{(a-1.1)^2} ---------------- (A)$

For the second statement,

x = (a-4.8), W = 9

=> $9 = \frac{1}{2}k(a-4.8)^{2}$

Now making k the subject of formula, we have:

$k = \frac{18}{(a-4.8)^{2} } ------------------------- (B)$

Equating A and B since k is constant, we have:

$\frac{10}{(a-1.1)^{2} } = \frac{18}{(a-4.8)^{2} }$

solving for the value of a

$8a^{2} +56.4a-208.62=0$

solving for a, we get:

a = 2.6801 or -9.7301

but since length cannot be negative, a = 2.68m

substituting the value of a in equation B, we have:

$k=\frac{18}{(2.68-4.8)^{2} }$

k = 4.005

HELP PLEASE ⚠️⚠️⚠️⚠️⚠️⚠️⚠️❗❗❗❗❓❓❓<br> Why does it matter that we protect African Wild Dogs?

pshichka [43]

Explanation:

African wild dogs are among the most effective predators in the world. They use extraordinary cooperation and teamwork to pursue, overhaul and bring down their prey.African wild dogs are struggling to cope with the rapid increase in human settlements and infrastructure development that are encroaching on their traditional range. They are perfectly adapted to their natural environment, but require vast territories to survive – much larger than most other carnivore species. This increased exposure to human contact poses numerous threats to the wild dogs’ survival.
