AU is the distance from the earth to the sun, and solar mass represents a measurement equal to the mass of our sun.
The units applied in astronomy is quite different from the units applied in daily life. The unit called astronomical units (AU) describes the distance from the earth to the sun. The unit solar mass represents the mass of the sun and is taken to be equal to 1.989 x 10^30 kilograms.
Therefore, the difference between the AU and solar mass is that; AU is the distance from the earth to the sun, and solar mass represents a measurement equal to the mass of our sun.

While moving at a constant speed on a level, snowy surface, a snowmobile rider throws a snowball vertically up-
wards. If the snowmobile continues moving at a constant velocity, the ball returns to the driver. Explain, using one of Newton's Laws of Motion why the ball lands ahead of the driver if the snowmobile stops.
The ball lands ahead of the driver if the snowmobile stops in obedience to the law of inertia.
According to Newton's first law of motion, an object continues in its state of rest or uniform motion unless it is acted upon by an unbalanced external force. This is also known as the law of inertia.
The law of inertia explains the reluctance of an object to stop when it has started moving and also the reluctance of objects to start moving. The ball lands ahead of the driver if the snowmobile stops in obedience to the law of inertia.

What are the two factors that affect the gravitational pull between two objects?
Answer:
hen dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance.
Explanation:
Suppose the gravitational force between two spheres is 30 N. If the magnitude of both masses doubles, and the distance between them tripled. What is the force between the masses?
If both masses double in size and their separation between them triples. 13..33 N will be the force between the masses.
What is gravitational force?Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.
Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.
Given data:
The gravitational force = 30 N
Mass 1 =m₁
Mass 2=m₂
Distance between charges = R
Condition given:
Mass 1 = 2m₁
Mass 2= 2m₂
Distance between charges = 3R
[tex]\rm F = \frac{Gm_1m_2}{R^2}[/tex]
Case 2;
[tex]\rm F'=\frac{G(2m_1)(2m_2)}{(3R)^2} \\\\ F'=\frac{4}{9} \frac{Gm_1m_2}{R^2} \\\\ F'=\frac{4}{9} F \\\\ F'=\frac{4}{9} \times 30 \\\\ F'=13.33 \ N[/tex]
Hence, the forces between the masses will be 13..33 N.

What water pressure must a pump that is located on the first floor supply to have water on the thirteenth of a building with a pressure of 35 lb/in2 Assume that the distance between each floors is 10ft.
The water pressure on the first floor must be 455 PSI in order to push the water to the 13th floor at the given pressure.
The given parameters;
Pressure on the 13 th floor, P₁ = 35 PSIDistance between each floor, d = 10 ftThe vertical pressure of the water is calculated as follows;
[tex]P = \rho gh\\\\\frac{P}{h} = \rho g\\\\\frac{P}{h} = k\\\\\frac{P_1}{h_1} = \frac{P_2}{h_2} \\\\[/tex]
The vertical height of the first floor from the 13th floor = 130 ft

While exercise generally benefits all of the glands, why is it particularly beneficial for the pancreas?
A.
Exercise increases the levels of the hormones that the pancreas produces.
B.
Physical activity positively impacts blood sugar, giving the pancreas less work.
C.
The pancreas can only properly regulate hormones when the body is in motion.
D.
The pancreas is structured more like a muscle than a gland, so it benefits from stretching.
PLEASE NO LINKS
Answer:
B
Explanation:
The pancreas is responsible for regulating blood sugar, exercise gives it less work to do
Excercise is particularly beneficial for the pancreas because physical activity positively impacts blood sugar, giving the pancreas less work. Correct option is B.
When you engage in physical activity, several things happen that benefit the pancreas:
Increased Insulin Sensitivity: Exercise helps improve the body's sensitivity to insulin. This means that cells become more responsive to the insulin signal, allowing glucose to enter the cells more effectively. This can help prevent insulin resistance, a condition where cells don't respond properly to insulin and blood sugar levels rise.
Improved Blood Sugar Regulation: Exercise can lower blood sugar levels by facilitating the uptake of glucose into cells for energy. This can reduce the burden on the pancreas to produce excess insulin to manage high blood sugar levels.
Reduced Risk of Type 2 Diabetes: Regular physical activity is associated with a reduced risk of developing type 2 diabetes, a condition characterized by impaired blood sugar regulation. By helping maintain healthy blood sugar levels, exercise supports the pancreas in its role of insulin production.

A block of mass m is initially at rest on a rough horizontal surface when a constant force F is exerted on it, as shown. The block accelerates to the right and is moving with speed v once it has moved a distance d. Which of the following equations can be used to solve for the force of friction exerted on the block by the surface?
The equations that can be used to solve for the force of friction exerted on the block by the surface is F- f = mv² / d
The constant force F is exerted on the block of mass and it accelerates with a speed, v and covering a distance of d in the direction of the force. The force of friction is an opposing force to the applied force.
Therefore,
using Newtons third law
F - f = ma
a = v/t
t = d/v
F - f = m × v / t
F- f = m × [tex]\frac{v}{\frac{d}{v} }[/tex]
F- f = m × v²/d
Therefore,

if a car travels around a circular track with a radius of 100 m once every 10s what will its average angular velocity around the track be?
Answer:
0.628 radians per second
Explanation:
Angular velocity
= 2pi/T
= 2(3.14159)/10
= 0.628 radians per second
The average angular velocity around the track is 62.8 m/s, using the circumference of the track as the total distance.
Average angular velocity:What information do we have?
Radius of track = 100 m
Time taken = 10s
Circumference of track = 2πr
Circumference of track = 2(3.14)(100)
Circumference of track = (2)(314)
Circumference of track = 628 m
Average angular velocity around the track = Circumference of track / Time taken
Average angular velocity around the track = 628 / 10
Average angular velocity around the track = 62.8 m/s

In which scenario below does the ball have more gravitational potential energy when sitting at the top. Why?
The B figure has got more gravitational potential energy because gravity can draw it up straight rather than in a fashion (A) that would leave it with less room to travel.
What is Gravitational Potential Energy?The work (energy exchanged) per mass that would be required to transport an object to a point from a set reference location is the gravitational attraction at that location. It mimics the electric potential, with mass acting as the charge. There is a negative potential at any finite distance because the benchmark location, where the potential is zero, is conventionally indefinitely far from any mass.
The subject of potential theory is based on the gravitational potential, sometimes referred to as the Newtonian potential in mathematics. The electrostatic and popular throughout the world fields produced by ellipsoidal bodies that are uniformly charged or polarized can also be resolved using this method.
