Answer:
55.56 watt
Explanation:
Work (W) = 1000 J
time (T) = 18 sec
power (P) = ?
We know power is the rate of doing work so
p = w / t
= 1000 / 18
= 55. 56 watt

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.

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.

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
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.

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
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 .

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?
I said that we should go this far this day and then we can get this far this week. I also said that if we go this fast then we can get this far. So really, I just made goals to help improve our ability,

How much work is done on an object by a force of 10.0 N pushing it 5.00 m?
Work is done on an object by a force of 10.0 N pushing it 5.00 m is 50.0 joule.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
Given parameters:
Force applied on the object is: F = 10.0 N.
Displacement of the object is: d = 5.00 meter.
Hence, Work is done on the object = force × displacement
= 10. N × 5.00 meter
= 50.0 Joule.
So, Work is done on an object by a force of 10.0 N pushing it 5.00 m is 50.0 joule.

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.
