45 rpm is greater/faster. Convert both measurements to the same unit rate:
45 rpm = (45 rev) / (1 min) = (45 rev) / (60 s) = 0.75 rps
4.71 rad/s = (4.71 rad) / (1 s) • (1 rev) / (2π rad) = (4.71 rev) / (2π s) ≈ 0.74962 rps

Felix selects a golf ball at random. Based on the information in the table, which statement is
true?
A The golf ball is more likely to be green than all other colors combined.
B The golf ball is equally likely to be pink, white, orange, or green.
C The golf ball is 2 times as likely to be orange as it is to be pink.
D The golf ball is 7 times as likely to be green as it is to be white.
The golf ball is two times as likely to be orange as it is to be pink. Therefore, option C is correct.
What is probability?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.

A piece of wire length 30cm and cross sectional area of 0.5mm^2 has a resistance of 5ohms at 20°c. It is then heated to a temperature of 150°c. Calculate it's resistivity at 20°c
Answer:
8.333*10^-6 ohms
Explanation:
Resistivity of a material is expressed as;
p = RA/l
R is the resistance of the material
A is the cross sectional area
l is the length of the material
Given
R = 5 ohms
A = 0.5mm^2
A = 5 * 10^-7m^2
l = 30cm = 0.3m
Substitute into the formula;
p = (5 * 5 * 10^-7m^2)/0.3
p = 25 * 10^-7/0.3
p = 0.0000025/0.3
p = 8.333*10^-6
Hence its resistivity at 20 degrees Celsius is 8.333*10^-6 ohms
What happend to the space pod in missing seconds?
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.

Why does the plane, tied on a string onto the ceiling, move in a horizontal circle, and why doesn’t the plane move up and down?
Answer:
There’s a tangential velocity and centripetal force. The object moves in a circle because it’s falling towards the center of the circle (point directly under string) but the velocity is such that the object never gets closer to the center
