Answer:
6 kilograms
Explanation:
force (N) = mass (kg) × acceleration (m/s²). an object of constant mass accelerates in proportion to the force applied. If the same force is applied to two objects of different mass, the heavier object has less acceleration than the lighter object. Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter.

Un neumático sin cámara, soporta una presión de 1.5 atm cuando la temperatura ambiente es de 300°K. ¿Qué presión llegará a soportar dicho neumático si, en el transcurso de un viaje, las ruedas alcanzan una temperatura de 67ºC? Atm
Answer:
El neumático soportará una presión de 1.7 atm.
Explanation:
Podemos encontrar la presión final del neumático usando la ecuación del gas ideal:
[tex] PV = nRT [/tex]
En donde:
P: es la presión
V: es el volumen
n: es el número de moles del gas
R: es la constante de gases ideales
T: es la temperatura
Cuando el neumático soporta la presión inicial tenemos:
P₁ = 1.5 atm
T₁ = 300 K
[tex] V_{1} = \frac{nRT_{1}}{P_{1}} [/tex] (1)
La presión cuando T = 67 °C es:
[tex] P_{2} = \frac{nRT_{2}}{V_{2}} [/tex] (2)
Dado que V₁ = V₂ (el volumen del neumático no cambia), al introducir la ecuación (1) en la ecuación (2) podemos encontrar la presión final:
[tex] P_{2} = \frac{nRT_{2}}{V_{2}} = \frac{nRT_{2}}{\frac{nRT_{1}}{P_{1}}} = \frac{P_{1}T_{2}}{T_{1}} = \frac{1.5 atm*(67 + 273)K}{300 K} = 1.7 atm [/tex]
Por lo tanto, si en el transcurso de un viaje las ruedas alcanzan una temperatura de 67 ºC, el neumático soportará una presión de 1.7 atm.

what would happen to our vision if the lens of our eyes were concave? defend your answer NO LINKS!!!
If the lens of our eyes were concave, we would not be able to see. We would be blind. This is because our eyes form a visual image on the same side of the lens at the object being viewed. Thus, a concave lens would result in the visual image focusing in front of the eye, not the retina inside the eye. This would mean that no signals would be sent to the brain, and vision would not be possible.

Where do human get the stuff they need to survive?
Answer:
Humans survive through gaining nutrients by eating
Answer:
We must have food, water, air, and shelter to survive. If any one of these basic needs is not met, then humans cannot survive. Oxygen is one of the most essential human needs. Our bodies need a consistent supply of it to function properly. Without access to oxygen, you can experience a condition known as cerebral hypoxia, which affects the brain. As little as five minutes without air can result in brain damage. We get food from plants and animals, we get water from rivers and streams, and we get shelter from building anything that is around.

An air track car with a mass of 6 kg and velocity of 4 m/s to the right collides with a 3 kg car moving to the left with a velocity of 2 m/s. After the collision, the 6kg car continues forward with a velocity of 1 m/s. What is the new velocity of the 3 kg car after the collision?
Remember that moment before collision is equal to the moment after collision.
[tex](m1 \times u1) + (m2 \times u2) = (m1 \times v1) + (m2 \times u2)[/tex]
Plugging in our values,
[tex](6 \times 4) - (3 \times 2) = (6 \times 1) + (3 \times v2) \\ 24 - 6 = 6 \times 3v2 \\ 18 = 18v2 \\ v2 = 1 {ms}^{ - 1} [/tex]
The velocity of the second car after the collision is 8 m/s.
What is law of conservation of momentum ?The law of conservation of momentum states that, within the domain, the total momentum before collision is equal to the momentum after collision.
Here,
Mass of the car to the right, m₁ = 6 kg
Mass of the car to the left, m₂ = 3 kg
Velocity of the first car before collision, u₁ = 4 m/s
Velocity of the second car before collision, u₂ = 2 m/s
Velocity of the first car after collision, v₁ = 1 m/s
According to the conservation of momentum,
(m₁u₁) + (m₂u₂) = (m₁v₁) + (m₂v₂)
(6x4) + (3x2) = (6x1) + (3v₂)
3v₂ = 24
Therefore, v₂ = 24/3
v₂ = 8 m/s
Hence,
The velocity of the second car after the collision is 8 m/s.

Why would you advice a person to sit rather than stand in a moving bus?
Answer:
Standing in a moving bus may lead the person fall when the driver will apply brake.
Explanation:
According to Newton's third law of motion, there is an equal and opposite reaction to every action. When the bus is moving, the person standing is in the state of rest. The moment the driver applies brake, the bus stops. The stopping of the bus makes the person in the stationary position change in motion. Because of this force, the person may fall and collide if he is standing instead of sitting in the moving bus.
A laptop computer adapter has a voltage of 19 v it has a resistance of 4.0 Ω and the adapter gets warm when operating. So determine the current going through the adapter
Answer:
Current, I = 4.75 Amps
Explanation:
Given the following data;
Voltage = 19 V
Resistance = 4 Ohms
To find the current;
Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.
Mathematically, Ohm's law is given by the formula;
[tex] V = IR[/tex]
Where;
V represents voltage measured in voltage.
I represents current measured in amperes.
R represents resistance measured in ohms.
Making current (I) the subject of formula, we have;
[tex] I = \frac {V}{R} [/tex]
Substituting into the formula, we have;
[tex] I = \frac {19}{4} [/tex]
Current, I = 4.75 Amps
A record player has a velocity of 33.33 RPM. How fast is the record spinning in m/s at a distance of 0.085 m from the center?
Answer:
0.297 m/s
Explanation:
It is 0.297 m/s. The study of rotational motion in the absence of forces is known as angular kinematics.
What is angular velocity?The angular velocity of an object is the rate at which it rotates or revolves around an axis in time. The Greek letter omega (, sometimes ) represents angular velocity. The SI unit of angular velocity is radians per second because it is measured in angle per unit time. Angular velocity (w) is a vector quantity in uniform circular motion and equals angular displacement (, a vector quantity) divided by time change (t). The arc length travelled (S) divided by the change in time (t) equals speed, which is also equal to |w|R. An example of angular velocity is a roulette ball on a roulette wheel, a race car on a circular path, and a Ferris wheel.To learn more about Angular Kinematics refer to:

What is the speed of a wave with a frequency of 100 hz and a wave length of .5 m?
Answer:
Explanation:
There are 2 ways to help with this. Explain the details, which are fairly simple in this topic, or give the formula. My hope is that an explanation will last longer than memorizing the formula. I give you both.

During a lab investigation, students added four 50 g masses to two boxes and arranged the boxes so that they were motionless on a pulley, as shown in the diagram. The students then followed the procedure described in the box. The students recorded their observations after
each procedure and reset the pulley system to the original conditions.
During which procedures did students observe an unbalanced upward force on Box 1?
Group of answer choices
Procedures 4 and 5
Procedures 3 and 4
Procedures 1, 2, and 3
Procedures 1, 3, and 5
Answer:
Procedures 4 and 5.
Explanation:
Both would cause the box to move up.
4, it becomes lighter
5, the other becomes heavier, pulling it down, causing box one to go up
Since we seek the action of force to push up box 1, the students observes an unbalanced upward force on Box 1 in procedures 4 and procedure 5.
In what procedures did students observe an unbalanced upward force on Box 1?Generally, In procedure 4 we added another mass to the box two, therefore, causing box one to experience an upward force.
Therefore, students observe an unbalanced upward force on Box 1 in procedure 4.
Procedure 5 we remove masses from box 1 resulting in box 2 becoming heavier, pulling it down.
Therefore, students observe an unbalanced upward force on Box 1 in procedure 5.

A 0.10 kg mass is oscillating on Planet X at a small angle from a light string of length 0.20 m with a period of
0.63 s.
What is the acceleration of gravity on Planet X?
Answer:
the acceleration of gravity on Planet X is 19.89 m/s^2
Explanation:
The computation of the acceleration of gravity on Planet X is shown below:
T = 2π√l ÷ √g
g = l ÷ (T÷ 2π)^2
= 4π^2l ÷ T^2
= 4π^2× 0.2 ÷ 0.63^2
= 19.89 m/s^2
Hence, the acceleration of gravity on Planet X is 19.89 m/s^2
