Answer:An electromagnet is a magnet that works with electricity. It can be switched on and off. The coils are nearly always made of copper wire because copper is such an excellent electrical conductor. Electromagnets have many uses.Permanent magnets are mainly used in small generators, and they have the advantage that they don't need a power supply. Electric magnets are iron or steel wound with wire. When electricity passes through the wire, the metal becomes magnetic and creates a magnetic field.

Answer:

From our investigation of what forces are like in a collision, we learned that when two

objects collide, a force is exerted on each object. The two forces are in opposite

directions but the same strength. This allowed us to infer that an equal strength force

was exerted on the space station and the pod, but in opposite directions.

As a result, the space station and the pod are moving in opposite directions. We need to

learn more about the effects of collisions on each object’s motion so we can report back

to Dr. Gonzales at the space agency.

You will use physical materials to gather data about

forces in a collision. You will also notice how objects

are affected by collisions. Students will use their

data to infer the force direction for objects in a

collision.

Based on the velocity change of each object,

what did you infer about the direction of forces

during a collision?

• We observed that the velocity of each object changed during a collision, so we can infer

that a force had to be exerted on each object. However, the motion of the objects

changed in different ways.

• The object that was moving forward slowed down, so I can infer that the force must have

pushed backward on this object.

• The other object started moving forward, so the force must have pushed forward on that

object. If one force was backward and one force was forward, then the forces pushed

the objects in opposite directions.

Answer:

Protons; electrons.

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.

Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons. All the physical properties of a mineral result from the mineral's internal arrangement of atoms.

The atomic number is always equal to the total number of protons, which is also equal to the total number of electrons. Protons are the positively charged particles that make up an atom while electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

A chemical element is denoted by [tex] X_{Z}^{A} [/tex]

Where;

X is the symbol of the element.

A is the atomic mass or number of nucleons.

Z is the atomic number or number of protons.

Therefore, the number of neutrons = A - Z

The golf ball is two times as likely to be orange as it is to be pink. Therefore, option C is correct.

Probability can be described as the branch of mathematics of numerical descriptions of how likely an event is to take place. The probability of an event can be a number between 0 and 1, where 0 indicates the impossibility of the event and 1 shows certainty.

Given, the number of pink balls = 4

The number of white balls = 11

The number of orange balls = 8

The number of green balls = 18

The total number of balls = 4 + 11 + 8 + 18 = 41

When Felix picks a golf ball at random. The golf ball is more likely to be pink = 4/41

The probability golf ball is more likely to be white = 11/41

The probability  golf ball is more likely to be orange = 8/41

The probability golf ball is more likely to be green = 18/41

Therefore, the golf ball is two times as likely to be orange as it is to be pink.

Answer: -10m/s

Explanation:

Velocity is solved using the equation displacement over time. Part C shows a displacement or change in x of 30 and a change in time of 3 secs (7-10) so the equation would be 30m/3s= -10m/s it is negative because look at the slope. Its decreasing right? So that means the objects is slowing down which means it can't have a positive velocity

The spring constant of the given bow spring is equal to  1.77 × 10⁵ N/m.

Hooke's law can be described as a law that states that the force (F) required to extend or compress a spring by displacement linearly with respect to that displacement along a straight line.

The spring force can be represented in the form of an equation:

F = -kx

where k is a spring constant of the spring and x is the deformation of the spring. The negative sign shows that force is restoring force.

The energy that can be stored in the spring when it is stretched is given by:

E = (1/2)kx²

Given, the energy stored in the spring when it is stretched, E = 1000J

The distance by which the bow spring is stretched, x = 0.15 m

2000 =  (1/2) × k (0.15)²

k = 1.77 × 10⁵ N/m

Answer:

If the track is horizontal and the string is pulled horizontally, the friction on the cart would be [tex]4.0\; \rm N[/tex].

Explanation:

Let [tex]m[/tex] denote the mass of this cart, and let [tex]a[/tex] denote the acceleration of this cart.

[tex]m = 3.00\; \rm kg[/tex].

[tex]a = 2.00\; \rm m \cdot s^{-2}[/tex].

Apply Newton's Second Law to find the net force on this cart.

[tex]\begin{aligned}\text{Net Force} &= m \cdot a\\ &= 3.00\; \rm kg \times 2.00\; \rm m\cdot s^{-2}\\ &= 6.00\; \rm N\end{aligned}[/tex].

The following forces act upon this cart:

Assume that the track is horizontal, and that the string was pulled horizontally. The normal force from the track would exactly balance the downward gravitational attraction from the earth. Hence, the [tex]6.00\; \rm N[/tex] net force on this cart would be equal (in size) to the size of the tension from the string ([tex]10.0\; \rm N[/tex]) minus the size of the friction from the track.

In other words:

[tex]\begin{aligned}&\text{Size of Net Force}\\ &= \text{Size of Tension} - \text{size of friction}\end{aligned}[/tex].

[tex]\begin{aligned}& 6.00\;\rm N = 10.0\; \rm N - (\text{size of friction})\end{aligned}[/tex].

[tex]\text{size of friction} = 10.0\; \rm N - 6.00\; \rm N = 4.0\; \rm N[/tex].
