A 2750 kg helicopter flies horizontally at constant speed. Air resistance creates a 7510 n backward force. What is the magnitude of the lift force created by the propellers
Answer:
Explanation:
Let lift force F be created by propellers at angle of Ф with the horizontal .
The vertical component of this force will balance the weight of helicopter and horizontal component will balance the air resistance .
F sinФ = mg = 2750 x 9.8 = 26950 N
F cosФ = 7510 N
Squaring and adding ,
F² = 26950² + 7510²
= 726302500 + 56400100
= 782702600
F = 27976.82 N .

Latitude plays a major role in determining the climate of an area. What causes some areas of Earth to receive less direct solar energy than others?
Answer:
Explanation:
The main cause of different parts of the earth receiving different amounts of solar energy is as a result of the tilt of the Earth. Having different latitudes also play a role in that, as latitudes are used to measure the distances between places on earth(together with longitude) receiving different amounts of solar energy also leads to having different atmospheric circulation. Making some places have more heat, while other places have lesser heat energies. Logically, the areas with higher presence of solar energy are going to be hotter than places with lesser presence of solar energy.

Answer:
16. 68.18 Km/h
17. 3 miles.
Explanation:
16. Determination of the speed
Distance travelled = 150 Km
Time = 2.2 hours
Speed =?
Speed is simply defined as the distance travelled with time. Mathematically, it is expressed as:
Speed = Distance / time
With the above formula, we can obtain the speed as follow:
Distance travelled = 150 Km
Time = 2.2 hours
Speed =?
Speed = Distance /time
Speed = 150 / 2.2
Speed = 68.18 Km/h
17. Determination of the distance.
Speed = 3 mph
Time = 1 hour
Distance =?
Speed = Distance /time
3 = distance / 1
Distance = 3 miles
In each cycle, a heat engine performs 710 J of work and exhausts 1480 J of heat. What is the thermal efficiency?
A) 0.24
B) 0.47
C) 1.7
D) 0.32
Answer:
D) 0.32
Explanation:
The computation of the thermal efficiency is given below:
Thermal efficiency is
= 710 J ÷ (710 J + 1480 J)
= 710 J ÷ 2,190 J
= 0.32
Hence, the thermal efficiency is 0.32
Therefore the last option is correct

When a guitar string is plucked, what part of the standing wave is found at the fixed ends of the string?(1 point)
the antinodes
the nodes
the resonance
the harmonics
A node is a place on a standing wave where the amplitude is the smallest. When a guitar string is plucked the nodes part of the standing wave is found at the fixed ends of the string.
What is a node?A node is a place on a standing wave where the amplitude is the smallest. The nodes at the ends of a vibrating guitar string, for example, are nodes.
The guitarist alters the effective length of the vibrating string and hence the note played by shifting the location of the terminal node through frets.

Un prisma rectangular con un volumen de 80 m^3 se sumerge hasta la mitad en agua, calcular la fuerza de empuje que recibe.(rho_(del agua)=1000 kg/m^3)
Answer:
400 kN
Explanation:
El principio de Arquímedes establece que, cuando un cuerpo está total o parcialmente sumergido en un fluido, experimenta un empuje hacia arriba que es igual al peso del fluido desplazado.
Dado que;
Volumen del bloque = 80m ^ 3
Densidad del agua = 1000 kg / m ^ 3
Empuje hacia arriba = 1/2 * 80 * 1000 * 10
Empuje hacia arriba = 400 kN

The diagram below shows a race car traveling around a racetrack at a constant speed of 150 km/hr.
B
According to the above information and diagram, at which points (if any) is the velocity of the car the same?
O Points A and B
O Points A and C
O Points B and C
O The velocity is not the same at any of the points.
Answer:
point a and c
Explanation:
point a and c
According to the above information and diagram, at Points A and C the velocity of the car is the same, so option B is correct.
What is velocity?When anything is moving, its velocity tells us how quickly that something's location is changing from a certain vantage point and as measured by a particular unit of time.
If a point moves along a path and covers a certain distance in a predetermined amount of time, its average speed over that period of time is equal to the distance covered divided by the travel time. A train traveling 100 kilometers in two hours, for instance, is doing it at an average speed of 50 km/h.
As the car accelerates from point A and decelerate at point B and then again accelerate from point B and gain the highest velocity at point C therefore, the velocity of the car is the same at point A and C.

A snowball is rolling down a grassy hill. Determine what force is causing the object to slow down or speed up. Sketch a free-body diagram, including arrows, force values, and label be sure the label the forces appropriately.
Answer:
Rolling Friction (round object on a flat surface) Speeding up.
Explanation:
Gravity continually pulls something such as a table, roster, or person down from the hill. Thus, when you bounce, gravity makes you to arrive on the territory. Friction, however, doesn't pull something down. Friction, however, doesn't pull something downstairs. ... Also, friction always operates identically to the surface in connection because of the sliding movement.
These pairs of forces are known as ____________-reaction pairs because one pushes against the other with an equal but opposite force.

Which is the first step in the process during the formation of molded fossils? A Sediment hardens into rock. B Sediment is eroded from rock. C Organisms are buried under sediment.
The first step in the process during the formation of molded fossils is that the sediment is eroded from rock. Thus, the correct option is B.
What is Fossil formation?Fossils are important as they provide important evidence for the evolution and the adaptation of plants and animal species to their environments. Fossil evidence helps in providing the record of how creatures have evolved and how this process can be represented through the help of a tree of life, showing that all the species are related to each other.
Four types of processes which contribute to the formation of a fossil include mineralization, carbonization, encrustation, and distillation. They occur once an organism has become fully trapped within the surrounding sediment, and it primarily depends up on the mineral composition of the silt and water.
Therefore, the correct option is B.

Answer:
1.) Identify a team or group you participated with for your physical activity. Describe how you became involved, two positive ways you behaved that benefited your team and that were a positive influence on the game.
On February 12th I ran with my sisters. One positive behavior was that I did not go slow, and I kept with the pase. Another positive behavior was when the other person got tired or fell, the other two people helped them up. Some ways that I influenced the group was, I pushed the other people to do good and I also pushed them to not give up. Another way that I influenced the group was, I did not hold them down, like when they sped up, I sped up.
2.) How can participation in team sports improve your overall fitness?
It can improve my fitness by showing me that if they can do it, so can I and if I do not, it is not because I cannot, it is because I will not. Another way that it can improve my fitness is, if we start to slow down, we can tell each other to keep going and if we keep going, then our skill ability level will go up and that is how we can get more fit.
3.) How did you adjust the strategy for the team sport that you played?
