Answer:

I = 4.28 [amp]

Explanation:

To solve this type of problems we must have knowledge of the law of ohm, which tells us that the voltage is equal to the product of resistance by current.

Initial data:

v = 1.5 [volt]

R = 0.35 [ohms]

v = I * R

therefore:

I = 1.5 / 0.35

I = 4.28 [amp]

aalyn [17]

Answer:

1080 meters

Explanation:

60sec in 1 minute

So, 3x60=180

  • 6m/s (one second is 6 meters)

So, 6x180=1080 meters

Explain, briefly, what the electrical field inside a microwave oven does to heat food.
yarga [219]

Answer:

Inside the strong metal box, there is a microwave generator called a magnetron. When you start cooking, the magnetron takes electricity from the power outlet and converts it into high-powered, 12cm (4.7 inch) radio waves. Thus the microwaves pass their energy onto the molecules in the food, rapidly heating it up.May 3, 2018

What are the horizontal and vertical velocities of a stunt bike that leaves a ramp at 100 km/hr and at an angle of 35 degrees?
Alex787 [66]

Horizontal velocity: 81.9 km/h

Vertical velocity: 57.4 km/h

Explanation:

We can solve this problem by resolving the velocity vector into its component along the horizontal and vertical direction.

The horizontal velocity of the stunt bike is given by:

v_x = v cos \theta

where

v = 100 km/h is the magnitude of the velocity

\theta=35^{\circ} is the angle of projection

Substituting, we find

v_x = (100)(cos 35^{\circ})=81.9 km/h

The vertical velocity instead is given by

v_y = v sin \theta

where

v=100 km/h

\theta=35^{\circ}

Substituting,

v_y = (100)(sin 35^{\circ})=57.4 km/h

How does the total momentum of the docked vehicle and station compare to the momentum of each object before the
Xelga [282]

The total momentum before the docking maneuver is  and after the docking maneuver is

Explanation:

Linear momentum  (generally just called momentum) is defined as mass in motion and is given by the following equation:  

 

Where  is the mass of the object and  its velocity.

According to the conservation of momentum law:

"If two objects or bodies are in a closed system and both collide, the total momentum of these two objects before the collision  will be the same as the total momentum of these same two objects after the collision ".

This means, that although the momentum of each object may change after the collision, the total momentum of the system does not change.

Now, the docking of a space vehicle with the space station is an inelastic collision, which means both objects remain together after the collision.

Hence, the initial momentum is:

Where:

is the mass of the vehicle

is the velocity of th vehicle

is the mass of the space station

is the velocity of the space station

And the final momentum is:

Where:

is the velocity of the vehicle and space station docked

Why is the surface salinity of the ocean higher in the subtropics than in equatorial regions?
larisa [96]
Evaporation is more contrasted with the rainfall which is less in the correlation of tropical locale. In tropical locale, protection is very little in light of mists. Alongside temperature, it is the main consideration in adding to changes in the thickness of seawater and consequently sea flow. Saltiness is the way to understanding the worldwide water cycle. 97% of the Earth's free water dwells in the seas. The water cycle is commanded by precipitation and evaporation.
