The mass of the worker is 75 kg, the radius of merry go round is 4.5m and the linear velocity of the merry go round is 4.1m.s.
a) The diagram is attached below.
b) The friction force while rotation will be equal to the centrifugal force, this is the reason why he will be able to go round,
So, we can write,
Friction force Fr = Centrifugal force
Fr = MV²/R
Where Fr is the friction force,
M is the mass of the worker,
V is the velocity of the merry go round,
r is the distance at which the worker is standing.
Putting all the values,
Fr = 75 x 4.1 x 4.1/4.5
Fr = 280.16N.
The friction required is 280.16N.
c) The distance she travelled by her after the first round will be equal to the circumference of the circle,
Distance = 2Πr
D = 2 x 22 x 4.5/7
D = 28.28m

in astronomy, it is important to look for trends in your data. based on the average latitude and rotation period of each sunspot, what is the trend for rotation period as it relates to latitude?
A time of "solar maximum" (or "solar max") is when the number of sunspots peaks, whereas a time of "solar minimum" is when they are few (or "solar min").
Every year, a different amount of sunspots are seen on the "surface" of the Sun. This cycle, which has an average duration of about eleven years, explains the rise and decline in sunspots counts. The "Sunspot Cycle" is the term used to describe the cyclical change in sunspot counts that was first observed in 1843 by German amateur astronomer Samuel Heinrich Schwabe. A time of "solar maximum" (or "solar max") is when the number of sunspots peaks, whereas a time of "solar minimum" is when they are few (or "solar min").
A recent sunspot cycle, for instance, lasted from the solar minimum in 1986, when 13 sunspots were observed, to the solar max in 1989, when more than 157 sunspots surfaced, and on to the subsequent solar minimum in 1996 (ten years after the solar minimum in 1986), when the number of sunspots had decreased to less than 9.
Through the course of the sunspot cycle, both the quantity and location of sunspots change. Sunspots typically start to emerge around a latitude of 15° closer to the equator as the solar cycle advances through solar max. Sunspots begin to appear relatively close to the solar equator, at about 7° North and South latitude, as the cycle comes to an end and solar min is once again approaching.
Around solar min, when sunspots of the current cycle are forming at low latitudes and sunspots of the next cycle are starting to form at high latitudes once more, there is frequently an overlap in this latitudinal migration tendency. Spörer's Law is the name given to the progressive equatorward drift of sunspots that occurs throughout the sunspot cycle and was originally observed in the early 1860s by the German astronomer Gustav Spörer and the Englishman Richard Christopher Carrington. Another English astronomer, Edward Walter Maunder, created the first "butterfly diagram" in 1904, which was a pictorial representation of this trend in sunspot migration.

4 Applications of named material with high specific heat capacity
Water has the highest specific heat capacity.
The specific heat capacity is measured in J/(kg K) or J/(kg °C), and it is the amount of heat (J) absorbed per unit mass (kg) of the material when its temperature rises by 1 K (or 1 °C).
Applications of water with highest specific heat capacity are:
Fomentation: Hot water bottles are employed for this process because, despite producing a lot of heat, the water stays hot for a long period inside the bottle. Water is utilized as a coolant in automobile radiators. It can absorb a lot of heat energy from the car's engine thanks to its high specific heat capacity, but its temperature doesn't get too hot.Bottled Wines: Wine bottles are stored submerged in water in colder areas.

Given is a feather dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s².
State second equation of motion.The second equation of motion is -

The values of velocity at point A,C,E and G is 15m/s, the values of velocity at point B, D, F and H is 10m/s, 20m/s, 30m/s and 40m/s respectively.
The projectile is launched from the top of the cliff with a horizontal velocity of 15m/s.
Throughout the motion of the projectile the velocity will have two components. On along vertical and one along horizontal.
Here, the direction of the acceleration is only downwards because only gravity is there and that in only downwards direction.
There is no acceleration in the horizontal direction. So, the velocity in the horizontal direction will never change.
So, the velocity at A,C,E and G is 15m/s throughout the motion.
We know that,
t = √(2h/g)
h = 1/2gt²
Where,
H is height of the cliff at that point,
t is the time,
g is gravity which is equal to 10m/s².
So, the height at point,
B is 1/2(10)(1)² = 5m
D is 1/2(10)(2)² = 20m
F is 1/2(10)(3)² = 45m
H is 1/2(10)(4)² = 50m.
The vertical velocity can be found by using the formula,
V = √2gh
So, vertical velocity at point,
B is √2(10)(5) = 10m/s.
D is √2(10)(20) = 20m/s.
F is √2(10)(45) = 30m/s.

In physics, mass is a numerical representation of inertia, which is a basic characteristic of all matter. The resistance a body of matter offers to a change in its speed or location as a result of the application of a force is what it is in essence. The change a force applies produces a change that is smaller the more mass a body has. The kilogramme, which is defined in terms of Planck's constant as equal to 6.62607015 1034 joule second, is the unit of mass in the International System of Units (SI). One kilogramme times one square metre per second squared is equivalent to one joule.

A force is a power that has the ability to alter an object's motion. A force can modify, or accelerate, the velocity of a mass-containing object. Intuitively, pushing or pulling can be used to describe force. As a vector quantity, a force is one that has both magnitude and direction.
The definition of magnitude is simply "distance or quantity." It displays an object's size, direction, or motion in absolute or relative terms. It is employed to indicate the size or scope of something.
The two main categories into which forces can be separated are: Forces in contact. Non-contact forces
A force can be appropriately described as a push or a pull. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another.

The speed of a moving object is the distance it travels in a given amount of time.
The distance travelled divided by the time gives the average speed of an object in a given time. The speed of an object is defined as the distance travelled per unit of time.

Newton's law of motion consists of three laws for the motion of a body, Where Newton's first law of motion states that An object at rest remains at rest, and an object in motion remains in movement at a steady speed and in a straight line unless acted on by an unequal force. Newton’s first law states that each object will stay at rest or in uniform motion in a straight line unless compelled to alter its state by the action of an outside drive. This tendency to stand up to changes in a state of motion is inertia. On the off chance that all the outside strengths cancel each other out, then there's no net drive acting on the object. In case there's no net constraint acting on the object, at that point the object will keep up a consistent speed.
