An electric oven has a resistance of 201 ohms and a voltage of 220 V. How much current does it draw?
asambeis [7]

1.1 A. An electric oven with a resistance of 201Ω and a voltage of 220V drwa a current of 1.1 A.

The easiest way to solve this problem is using the Ohm's Law I = V/R.

An electric oven has R = 201Ω, and a drop of voltage V = 220v, solve using I = V/R:

I = 220V / 201Ω

I = 1.09 A ≅ 1.1 A

Determine the thrust produced if 1.5 x 10^3 kg of gas exits the combustion chamber each second, with a speed of 4.00 x 10^3 m/s.
ozzi

Answer:

The thrust is 6\times 10^6\ N

Explanation:

Given that,

Mass of gas, m=1.5\times 10^3\ kg

The rate at which the gas is expelling, \dfrac{dv}{dt}=4\times 10^{3}\ m/s

We need to find the thrust produced by the gas.

We know that force is equal to the rate of change of momentum. So,

F=\dfrac{p}{t}

Also, p = mv

F=\dfrac{mv}{t}

So,

F=1.5\times 10^3\times 4\times 10^3\\\\F=6\times 10^6\ N

So, the thrust is 6\times 10^6\ N

How big the sun is compared to the planets
Ksivusya [100]
<span>The sun's circumference is about 2,713,406 miles (4,366,813 km). The total volume of the sun is 1.4 x 1027 cubic meters. About 1.3 million Earths could fit inside the sun. The mass of the sun is 1.989 x 1030 kilograms, about 333,000 times the mass of the Earth. hope this helps! :) please chose brainlest

A transformer has a primary voltage of 115 V and a secondary voltage of 24 V. If the number of turns in the primary is 345, how
Eduardwww [97]
Here's a fun and useful factoid:

               The ratio of the voltages on a transformer is the same
               as the ratio of the number of turns in each winding.

So the ratio of  (345 to the secondary turns)  is  (115V to 24V).

That's a proportion.

                 (115/24)  =  (345/x)

I'll bet you can take it and solve it from here.
Just cross-multiply in the proportion and etc. etc.

Foraging bees often move in straight lines away from and toward their hives. Suppose a bee starts at its hive and flies 500 m du
Ainat [17]

Answer:

The distance of the bee from the hive is 740 m.

Explanation:

Given that,

Bee starts fly 500 m due east, 430 m west and 670 m east.

The direction of the bee

500 m in positive direction

430 m in negative direction

670 m in positive direction

We need to calculate the net distance

Using formula of distance

D=500-430+670

D=740\ m

Hence, The distance of the bee from the hive is 740 m.
