A 10-ohm resistor has a constant current. If 1200 C of charge flow through it in 4 minutes what
Amanda [17]

Answer:

B 5.0 A .

Explanation:

Hello.

In this case, since we know the charge (1200 C), time (4 min =240 s) and resistance (10Ω) which is actually not needed here, we compute the current as follows:

I=\frac{Q}{t}

Then, for the given data, we obtain:

I=\frac{1200C}{4min}*\frac{1min}{60s}\\\\I=5A

Therefore, answer is B 5.0 A .

Best regards!

imagine that two balls, a basketball and a much larger exercise ball, are dropped from a parking garage. If both the mass and ra
tiny-mole [99]

Hypothesis

Let there is no air drag or any other resistance force due to surrounding

Now the force equation of ball is given as

F = mg

ma = mg

a = g

so the ball will be dropped down by acceleration a = g and this acceleration is independent of size and mass of the ball

So in this case both balls will be dropped by same acceleration.

So here both balls will hit the ground at same time

In Europe, gas cost approximately €0.98 per liter. How many dollars($) per gallon is this? ​ using a factor method
bixtya [17]

Answer:

€0.98 per liter = 4.377 doller per gallon

Explanation:

It is given that, In Europe, gas cost approximately €0.98 per liter. We need to convert it into dollars($) per gallon.

We know that, 1 euro = 1.18 United States Dollar

1 litre = 0.264172 US gallon

Cost of gas in Europe is €0.98 per liter.

0.98\ \text{euro/ liter}=\dfrac{0.98\times 1.18\ \text{doller}}{0.264172\ \text{gallon}}\\\\=4.377\ \text{doller/gallon}
