What is the current in a circuit with a 9.0 V battery and a resistance of 36.0 ohms

Physics
1 answer:
Vaselesa [24]3 years ago
6 0
Ohm's law states that the voltage within an electrical circuit is equal to the product of the current and the voltage. Mathematically it is written as V=IR where V is the voltage, I is the current and R is the resistance. If a circuit has a voltage of 9.0 Volts and a resistance of 36.0 Ohms, the current is I = V / R = 9.0/36.0 = 0.25 Amps.

In a collision between an electron and a hydrogen atom, it is useful to select both objects as the system because which of these
lukranit [14]

Answer:

Explanation:

Because of the following ,it is useful to select both objects as the system during  collision between an electron and a hydrogen atom

1. The total momentum of the system does not change during the collision.

2.The forces the objects exert on each other are internal to the system and don't change the total momentum of the system.

3. During the time interval just before to just after the collision, external forces are negligible.

vector J is 3250m long in a 38.4 direction. Vector K is 1822 m long in a 58.8 direction. Find the magnitude and direction of the
garik1379 [7]

Answer:

The resultant vector has a magnitude of 4998 m and a direction of 45.7°.

Explanation:

The x component of the resultant vector is the sum of the x components of each individual vector.

x = 3250 cos 38.4 + 1822 cos 58.8

x = 3490.8

Similarly, the y component of the resultant vector is the sum of the y components of each individual vector.

y = 3250 sin 38.4 + 1822 sin 58.8

y = 3577.2

The magnitude can be found with Pythagorean theorem:

√(x² + y²)

√(3490.8² + 3577.2²)

4998

The direction can be found with trigonometry:

atan(y / x)

atan(3577.2 / 3490.8)

45.7°

The resultant vector has a magnitude of 4998 m and a direction of 45.7°.

You are riding your bike to the mall. You travel the first mile in 10 minutes. The last mile takes you 15 minutes. This is an ex
sweet [91]
If the person if slowing down, then this would mean that this would actually be "negative acceleration". Sense this person first did a mile in 10 minutes, and then the next mile that this person did was actually 15 minutes, then this shows you that they actually went a lot slower. And this is why this would be a great example of "negative acceleration".
