3730 watts equals about 5 horsepower.

Since 1 horsepower = 746 watts, 3730 watts would equals to about 5 horsepower (3730/746 = 5).

The object represented by this graph is moving
Vinil7 [7]

The object represented by this graph is moving toward the origin at constant velocity.

Option 3.

<u>Explanation:</u>

In the figure, x-axis is representing increase in the time and y-axis is presenting increase in the distance from bottom to up. But the line in the graph which is plotted is decreasing from high distance to small distance with increase in time. So this indicates that as the time is increasing, the distance is decreasing.

And the object is moving toward the origin as the distance of the object motion is found to decrease with increase of time as per the graph. But the slope of the graph is found to be almost constant, this indicates that the velocity of the object is constant. Thus, the object represented by this graph is moving toward the origin at constant velocity.

A skateboarder shoots off a ramp with a velocity of 7.1 m/s, directed at an angle of 61° above the horizontal. The end of the ra
dsp73

Answer:

Highest point reached  = 3.37 m

Explanation:

Initial velocity, = 7.1 m/s

Initial vertical velocity = 7.1 sin 61 = 6.21 m/s

Consider the vertical motion of skateboarder,

We have equation of motion, v² = u² + 2as

          Initial velocity, u = 6.21 m/s

          Acceleration, a = -9.81 m/s²

          Final velocity, v = 0 m/s

         Substituting

                       v² = u² + 2as

                       0² = 6.21² + 2 x -9.81 x s

                       s = 1.97 m

So from ramp the position it goes up by 1.97 m

       Highest point reached = 1.97 + 1.4 = 3.37 m

Suppose that a constant force is applied to an object. newton's second law of motion states that the acceleration of the object
amid [387]

Newton’s second law states that force is the product of mass and acceleration. This is expressed mathematically as:

F = m * a

Where F = force, m = mass, a = acceleration

Since in the given problem, the force is constant or same force is acting upon two objects. Therefore we can simply equate the expression m * a of the 2 objects.

m1 * a1 = m2 * a2

Where m1 = 2 kg, a1 = 38 m/s^2, m2 = 19 kg. Therefore finding for a2:

2 kg * 38 m/s^2 = 19 kg * a2

<span>a2 = 4 m/s^2     (ANSWER)</span>

What produces the magnetic field of an electromagnet?
andrew11 [14]

An electromagnet is a magnet whose magnetic field is created when electricity is flowing.

<h2>What is an electromagnet?</h2>

A device consisting of an iron or steel core that is magnetized by electric current in a coil that surrounds it.

<h2>What is magnetic field?</h2>

Magnetic force is defined as the space surrounding a magnet in which magnetic force is exerted.

<h2>What is electricity?</h2>

A form of energy created by charged or moving <em>electrons</em> or <em>protons</em>.

<h2>What does it mean when electricity is flowing?</h2>

The movement of energy is called a flow. The flow of electricity through a wire can be thought of as being similar to the flow of water through a pipe. Electricity usually flows in specially protected wires, but it can also move around using many other objects.

<h2>How does a magnetic field and the flow of electricity relate?</h2>

The electromagnetic force produces two related phenomena: electricity and magnetism. They combine to generate electromagnetism. A magnetic field is created by a moving electric charge. Electric charge movement is induced by a magnetic field, resulting in an electric current.

<h2>What produces a magnetic field? </h2>

Electric charges in motion. Charged particles in motion have both an electric field and magnetic field associated with them.

<h2>How does an electromagnet work?</h2>

An electric current flows through a coil of wire. This produces a magnetic field in the wire. The sides of the coil that carry current at 90 degrees to the magnetic field experience a force as they interact with the magnetic field.
