Answer:
I would hit it as hard as you can with the club.
Explanation:
well one thing that I like to do is hit the golf ball as hard as possible with the club.
This is because for me, when I do that, I can normally get more momentum which means I also get a farther hit.

In winter, your classroom is warmed by a heater. Your teacher asks you to close the window because "this will stop the cold from getting in". Explain what is actually happening to the flow of heat in this scenario.
When the window is closed the heat is trapped inside the classroom which is circulating around the room but when the window is opened, the heat is escaping so most of the heat is escaping rather than circulating the room.
In winter, your classroom is warmed by a heater. Your teacher asks you to close the window because "this will stop the cold from getting in" because of the thermal gradient present between the outside colds air and the warm air present inside the room, as the window gets closed the outside air would not able to extract the thermal energy of the warm air present inside the room.
What is thermal energy?It can be defined as the form of the energy in which heat is transferred from one body to another body due to their molecular movements, thermal energy is also known as heat energy.
Thermal energy can be produced with help of various means such as by burning fossil fuels, with the help of solar energy.
As given in the problem statement In winter, your classroom is warmed by a heater. Your teacher asks you to close the window because "this will stop the cold from getting in because when the window is closed the cold air from the outside would not be able to extract the heat from the warmed air present inside the room
Thus, the flow of heat would get obstructed by the closing of the window

An airplane is flying in a horizontal circle at a speed of 490 km/h. If its wings are tilted at angle ɵ = 45° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface.
The radius of the circle in which the plane is flying is 1887 m.
What is aerodynamic lift?The aerodynamic lift is the force that keeps the aircraft flying in the air.
Let the aerodynamic lift be F1 sinθ= mv^2/R ---- (1)
and F1 cosθ= mg --------- (2)
Equating (1) and (2) and eliminating the mass;
R = v^2/ g tanθ
Where v = 490 km/h or 136 m/s
R = (136)^2/9.8 * tan 45
R = 18496/ 9.8

if nominal gdp is 1800 and the money supply is 450, then what is velocity?
Answer:
Explanation:
answer: 4 velocity.
if nominal gdp is 1800 and the money supply is 450, then what is velocity?
4 velocity.
If the nominal GDP is 1800 and the money supply is 450, then the velocity of money would be 4.
The total value of goods and services generated in an economy during a given time period, usually a year, is referred to as nominal GDP and is not adjusted for inflation. It depicts what products and services are now selling on the market.
Given:
Nominal GDP, PQ = 1800
Money supply, M = 450
From equation of exchange:
MV = PQ
V = (PQ) ÷ M
V = (1800) ÷ (450)
V = 4
Hence, if the nominal GDP is 1800 and the money supply is 450, then the velocity of money would be 4.

The coefficient of kinetic friction between the block and the horizontal surface will be 1.597.
What is kinetic friction?A force that acts among sliding parts is referred to as kinetic friction. A body moving on the surface is subjected to a force that opposes its progressive motion.
The given data in the problem is;
μ is the coefficient of kinetic friction=?
m is the mass of the block=10 kg
g is the acceleration due to gravity= 9.81 m/s²
Acceleration of block(a)=20 m/s²
Force (F)= 50 N
θ=30°
There are two forces to act on the block, one is the force directed while the other was the friction force opposing the motion.
From the newton's second law;
F= ma
F-f = ma
Fcos30°- μmg=ma

O A. Gravity doesn't exist between the Earth and the sun.
B. Gravity exists in the whole universe.
C. Gravity is a force that pushes two or more objects apart.
D. Gravity exists between two or more objects that have mass.
Answer:
B and D
Explanation:
A is wrong because objects with mass have gravity and the Earth and Sun both have mass. As we know, the Earth orbits around the Sun and the reason si because gravity.
B is corrects because throughout the whole universe there are objects like planets and meteors and more. All these objects have gravity because they have mass.
C Gravity pulls things together that is why we are on Earth and not pushed away into space.
D is correct, using Sun and a meteor. When a meteor comes within the gravity range of the sun, the sun pulls the meteor toward it. Without anything around the sun, nothing happens because there is nothing to pull.

b. the pulley rope is pulled more than 1 meter, but less than 3 meters.
c. the pulley rope is pulled 3 meters.
d. the pulley rope is pulled more than 3 meters.
Answer:
b
Explanation:
It takes less effort to lift a piano with a pulley. If the piano is lifted 3 meters, then the pulley rope is pulled more than 1 meter, but less than 3 meters.
It takes less effort to lift a piano with a pulley. If the piano is lifted 3 meters, then. The correct answer is a. the pulley rope is pulled 1 meter.
When lifting a piano using a pulley system, the distance the pulley rope is pulled will be the same as the distance the piano is lifted. This is due to the mechanical advantage of the pulley, which reduces the amount of effort needed to lift the piano but does not change the distance the rope is pulled.
In a simple single fixed pulley system, where one end of the rope is attached to a fixed point and the other end is used to lift the piano, the distance the pulley rope is pulled will indeed be the same as the distance the piano is lifted.
