Answer:
it right. Its The Iron Nail i just did it and i got correct (:
Explanation:
The core of the electromagnet if In an electromagnet that is made up of a D-cell battery with wire wrapped around an iron nail, the ends of the wire being taped to the battery is iron nail so, option D is correct.
What is an electromagnet?A coil surrounding a magnetic core through which an electric current is conducted to magnetize the core is an electromagnet. Wherever controlled magnets are needed, such as in devices where the magnetic flux needs to be adjusted, reversed, or turned on and off, an electromagnet is utilized.
The idea of the magnetic circuit systematizes the engineering design of electromagnets. The ampere-turns of the coil that creates the magnetic field and magnetic flux in the magnetic circuit are known as the magneto motive force F, or Fm, in this context.
Thus, the core is an iron nail.

What force must be applied to the end of a rod along the x-axis of length 2.25 m in order to produce a torque on the rod about the origin of 11 z-hat N·m? Choose among the available options below. x,y,z,-z
Answer:
4.9N approx.Explanation:
Step one:
given data
length of rod r= 2.25m
Required torque = 11 Nm
Required
The force needed to produce a torque of 11Nm
Step two:
"By definition, Torque is the twisting force that tends to cause rotation.
The point where the object rotates is known as the axis of rotation."
Mathematically,
[tex]\tau = rF\sin\theta[/tex]
[tex]\tau[/tex] = torque
r = radius
F = force
[tex]\theta[/tex] = angle between F and the lever arm
in this case is zero
[tex]\tau = rF\\\\F=\tau/r[/tex]
substituting we have
F=11/2.25
F=4.88N
F=4.9N approx.

Answer:
truck 1 has the most velocity
Explanation:
Because it weights less which means it faster and yea
One group approached their investigation by dropping a mass so it
fell vertically downward. They planned to measure the position of the
mass as it descended using a motion detector. They checked whether
the motion detector that they were using was sensitive enough to
capture the motion during the fall, and they were satisfied.
Given that they are measuring the motion (position, velocity, and
acceleration) of the mass, the students can only measure
gravitational potential energy and kinetic energy; any other form of
energy is undetectable. If they hope to see that energy is conserved
in this system, which of the following assumptions must be true (or
approximately true)?
Air Resistance is negligible
The initial vertical velocity of the mass is negligible.
Answer:
Air Resistance is negligible
Explanation:
If they hope to see that energy is conserved, then energy must not be gained or lost during the experiment. That is, loss due to air resistance must be negligible.
Answer:
air resistance negligible=true

What causes volcanoes to form in the middle of plates?
Science, 7th
Answer:
As a plate sinks deep into a subduction zone, it heats and begins to melt, forming magma. If the magma reaches the surface it can build tall volcanic mountains.
Explanation:
Answer: " Most volcanoes form along plate boundaries. Volcanoes are common along tectonic plate boundaries where oceanic plates sink beneath other plates. As a plate sinks deep into a subduction zone, it heats and begins to melt, forming magma. If the magma reaches the surface it can build tall volcanic mountains. "

Which of the following would increase the gravitational force of attraction between two objects?
A.-Doubling the mass of both objects, only
B.-Doubling the mass of both objects and doubling the distance between the objects
C.-Doubling the mass of one object and doubling the distance between the objects
D.-Doubling the distance between the objects, only
Answer:
Doubling the mass of both objects
Explanation:
If you double the mass of both objects, the gravitational force will quadruple, if you move the objects away from each other, the gravitational force will decrease
The gravitational force of attraction is increased by doubling the mass of both objects.
According Newton's law of Universal gravitation force, two objects in the universe attracts each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of distance between them.
[tex]F = \frac{Gm_1 m_2}{R^2}[/tex]
where;
R is the distance between the two objectsThus, we can conclude that by doubling the mass of both objects or reducing the distance between them, the gravitational force of attraction increases.

What average net force is required to stop a 1950 kg car in 10.5 s if it’s initially traveling at 28m/s
Answer:
An average net force of 5200 N is needed to stop the car
Explanation:
Cinematics and Dynamics
Cinematics describes the variables involved in the movement without dealing with its causes. There are four main concepts in cinematics: Velocity (or its scalar equivalent, the speed), acceleration, time, and displacement (or the scalar equivalent, distance).
The acceleration can be calculated by:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
The initial speed is vo=28 m/s, it stops (vf=0) in t=10.5 seconds, thus the acceleration is:
[tex]\displaystyle a=\frac{0-28}{10.5}[/tex]
[tex]a = -2.67~m/s^2[/tex]
The acceleration is negative because the car loses speed.
Knowing the mass of the car m=1950 Kg, we can calculate the net force required to stop the car by using the formula:
F = m.a =1950*2.67
F = 5200 N
An average net force of 5200 N is needed to stop the car

Consider an elevator carrying Kermit the frog weighing 4000.0 N is held 5.00 m above a spring with a force constant of 8000.0 N/m. The elevator falls onto the spring while subject to a frictional force (brake) of 1000.0 N. Determine the maximum compression distance, x, of the spring.
Answer:
Maximum compression distance (x) = 2.236 m (Approx)
Explanation:
Given:
Weight of frog = 4,000 N
Height = 5 m
Constant force = 8,000 N/m
Frictional force = 1,000 N
Find:
Maximum compression distance (x)
Computation:
Using Law of conservation;
mgh = 1/2(k)(x)²
4,000(5) = 1/2(8,000)(x)²
Maximum compression distance (x) = 2.236 m (Approx)

How do u know that liquid exerts pressure ?
Answer:
All fluids exert pressure like the air inside a tire. The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions.

Hope this helps!! Please consider marking brainliest! Have a good one!!A 615.00 kg race car is uniformly traveling around a circular race track. It takes the race car 20.00 seconds to do one lap around the 80.00 m radius circular track. What is the frequency of the race car's circular motion?
Answer:
The value is [tex]f = 0.05 \ Hz[/tex]
Explanation:
From the question we are told that
The mass of the car is [tex]m = 615 \ kg[/tex]
The period of the circular motion is [tex]T = 20 \ s[/tex]
The radius is [tex]r = 80 \ m/s[/tex]
Generally the frequency of the circular motion is
[tex]f = \frac{1}{T }[/tex]
=> [tex]f = \frac{1}{ 20 }[/tex]
=> [tex]f = 0.05 \ Hz[/tex]
