Explanation:
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
what is the average speed of the object at 8 seconds accelerate without speeding up
because i said so
the answer is 80 diveded by 8 equalzzzz
Transforme: a) 2 km em m b) 1,5 m em mm c) 5,8 km em cm d) 0,4 m em mm e) 27 mm em cm f) 126 mm em m g) 12 m em km
Answer:
a) 2000 m
b) 1500 mm
c) 580000 cm
d) 400 mm
e) 2.7 cm
f ) 0.126 m
g) 0.012 km
Explanation:
Transform
a) 2km to m
1 km = 1000m
hence : 2 km = 2 * 1000 = 2000 m
b) 1.5m to mm
1 m = 1000 mm
hence: 1.5 m = 1.5 * 1000 = 1500 mm
C) 5.8 km to cm
1 km = 100000 cm
hence ;5.8 km = 5.8 * 100000 = 580000 cm
D) 0.4 m to mm
1 m = 1000 mm
hence; 0.4 m = 0.4 * 1000 = 400 mm
E) 27 mm to cm
1 mm = 0.1 cm
hence ; 27 mm = 27 * 0.1 = 2.7 cm
F) 126mm to m
1 mm = 0.001 m
hence ; 126 mm = 126 * 0.001 = 0.126 m
G) 12m to Km
1 m = 0.001 km
hence ; 12 m = 12 * 0.001 = 0.012 km

2.Joan is taller than Stefan. Stefan is taller than Patrick. Joan is taller than Patrick
3.the sides of rhombus are equal.
4.A prime number has exactly two factors, 1 and itself. For example, 13 is a prime number because the only factors of 13 are 1 and 13.
________ 8. The pH of a solution is a measure of the concentration of H+ ions in it. TRUE OR FALSE
Answer:
False.
Explanation:
Potential of Hydrogen is the full form of PH.
Potential of Hydrogen tells about the acidity or basicity of the solution.
The pH of a solution is a measure of the concentration of hydrogen ions [tex](H+)[/tex] ions and hydroxide ions [tex](OH-)[/tex] in a solution.
So, the given statement is false.
How long would it take for a car to travel 22km if it has an average speed of 55 km/hr
Distance = (speed) x (time)
Time = (distance) / (speed)
Time = (22 km) / (55 km/hr)
Time = (22/55) (hr)
Time = 0.4 hour (that's 24 minutes)

A wave has a wavelength of 0.02m and period of 8.0*10^-2 seconds. calculate it's speed. (showing working)
Answer:
[tex]v = 0.25m/s[/tex]
Explanation:
Given
[tex]\lambda = 0.02m[/tex] --- Wavelength
[tex]T = 8.0 * 10^{-2}s[/tex] --- Period
Required
Determine the velocity of the wave
This is calculated using:
[tex]v = \frac{\lambda}{T}[/tex]
[tex]v = \frac{0.02m}{8.0*10^{-2}s}[/tex]
[tex]v = \frac{0.02m}{8.0*0.01s}[/tex]
[tex]v = \frac{0.02m}{0.08s}[/tex]
[tex]v = 0.25m/s[/tex]
Hence, the velocity is 0.25m/s

A dwarf planet is likely to
O A. have a bright tail and a glowing nucleus
O B. have chunks of rocks and that never clump together
O C. have a liquid hydrogen layer that surrounds a solid core
O D. have objects similar in mass orbiting nearby
Answer:
a have a bright tail and a glowing nucleus
A dwarf planet is most likely to have a bright tail and a glowing nucleus. Thus, the correct option is A.
What is a dwarf planet?A dwarf planet is a small planetary-mass object which is in direct orbit that of the Sun, it is smaller than any of the eight classical planets however it is still a world in its own right.
The prototypical dwarf planet is Pluto. The dwarf planets is that the geologically active bodies, which is an expectation that was borne out in 2015 by the Dawn mission to Ceres and the New Horizons mission to Pluto.
Dwarf planets always being in orbit around the Sun. They are not being a satellite of a planet. They having a mostly round shape due to its own gravity. They also have not cleared its neighboring region of debris.
Therefore, the correct option is A.

Subsistence farming and Intensive farming
Answer:
Subsistence farming is growing food for your own and your family's direct consumption. Like a backyard vegetable garden, but with fruit, starch crops, and animals as well. Intensive agriculture is anything that really works the land hard. The inputs cost money, so it is generally only done for profit

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 .
PLEASE HELP!!! ✨✨✨✨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.
2. How can participation in team sports improve your overall fitness?
How did you adjust the strategy for the team sport that you played?
4. Describe the positive outcomes that might result from including players with less ability or
even a disability on your neighborhood team.
5. Describe the alternative sport experience you completed and why you chose it.
6. Identify one individual or dual activity and one alternative or extreme activity you chose to
participate in and how you used offensive and defensive strategies in the game.
7 Did you meet your goal throughout this activity log? Why or why not?
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?
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,
4.) Describe the positive outcomes that might result from including players with less ability or even a disability on your neighborhood team.
We all go to the pase that everyone can go at first and then work our way up as a group and if one person needs to go slower, then we all go slower and keep going together.
5.) Describe the alternative sport experience you completed and why you chose it.
I completed running and biking because I really love biking and I am passionate about it because it is very relaxing and calming. I also completed running because I wanted to have something that I could rotate with so that I did not get tired of biking.

Explanation:
A 40N force is applied to a spring constant of 100 N/m how far can this spring be compressed by the force
Answer:
Extension, e = 0.4 meters
Explanation:
Given the following data;
Force = 40N
Spring constant, k = 100N/m
To find the extension;
Force = spring constant * extension
Substituting into the equation, we have
40 = 100 * extension
Extension, e = 40/100
Extension, e = 0.4 meters
Therefore, the spring can be compressed by the force over a distance of 0.4 meters.
