Answer: covalent bond
Explanation:
since sulfur and oxygen are both non-metals it forms a covalent bond
Most likely, sulfur and oxygen atoms create a covalent bond.
What is an ionic bond?Ionic bonding includes an electron transfer, in which one atom acquires an electron and the other loses an electron.
One of the ions formed has a negative charge (anion), whereas the other has a positive charge (cation)
The atoms link together to create a molecule because their opposing charges attract one other.
The type of chemical bond that involves the transfer of electrons between atoms will be an ionic bond.
Covalent bonds are chemical bonds that keep atoms of different elements together while sharing electrons.
Hence, most likely, sulfur and oxygen atoms create a covalent bond.

Waves will transmit through wood, hydrogen gas, milk and water.
Waves are disturbances that propagates energy usually through a material medium.
Most mechanical waves pass through the given medium. Only electromagnetic waves do not really require a material medium for their propagation. They can be propagated through a vacuum.
A truck weighing 3.0 × 104
newtons was driven up a
hill that is 1.6 × 103
meters long to a level area that
is 8.0 × 102
meters above the starting point. If the
trip took 480 seconds, what was the minimum power
required?
Answer:
5.0x10^4
Explanation:
Im gunna geuss that you didn't add the exponents so...
P=power
F=force
d=displacment
P=Fd
equation:
3.0x10^4(1.6x10^3 - 8.0x10^2)/480
=30000(800)/480
=50000 or 5.0x10^4
The minimum power required, if a truck weighing 3 × 10 ⁴ newtons were driven up a hill that is 1.6 × 10 ³ meters long to a level area that is 8.0 × 10 ² meters above the starting point, is 5 × 10 ⁴ Watt.
What is power?Power is the rate at which work is accomplished or energy is delivered in science and engineering. It can be written as W/t, which is the product of the amount of work finished (W) or energy transferred (E) divided by the amount of time (t).
A low-powered motor can carry out the same amount of work slowly, whereas a high-powered motor can finish it rapidly. To measure work (or energy) per unit of time, power units include foot-pounds per minute, joules per second (or watts), and ergs per second.
Given:
The weight of the truck, F = 3 × 10 ⁴ N,
The length of the hill, s = 1.6 × 10 ³ m,
The distance travelled, S = 8 × 10 ² m,
The time of the trip, t = 480 sec,
Calculate the power by the formula given below,
[tex]Power = Force \times displacement / time[/tex]
P = 3 × 10 ⁴ × (1.6 × 10 ³ - 8 × 10 ²) / 480
P = 5 × 10 ⁴ Watt
Therefore, the minimum power required, if a truck weighing 3 × 10 ⁴ newtons were driven up a hill that is 1.6 × 10 ³ meters long to a level area that is 8.0 × 10 ² meters above the starting point is 5 × 10 ⁴ Watt.

If the Sun has 28 times more gravity than Earth,
what is your weight on the Sun?
If someone have weight that is force due to gravity is X than on the sun it will become 28 X.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Mass of body is constant on any place in the universe and weight changes with acceleration due to gravity so, at sun weight will be 28 X.
If someone have weight that is force due to gravity is X than on the sun it will become 28 X.

CUAL DE LAS SIGUIENTES LEYES NO PERTENECEN A LOS 3 PRINCIPIOS DE NEWTON? 1.LEY DE LA ATRACCION 2.LEY FUNDAMENTAL DE LA DINAMICA 3.LEY DE ACCION Y REACCION 4.LEY DE LA INERCIA
Answer:
La Ley de atracción no pertenece a los tres principios de Newton.
Explanation:
Las leyes de Newton son tres principios que sirven para describir el movimiento de los cuerpos, basados en un sistema de referencias inerciales (es aquél que está en reposo o se mueve con velocidad constante, es decir, no tiene aceleración).
Las 3 leyes de Newton son:
Primera Ley o Ley de Inercia : Esta ley enuncia que todo cuerpo permanece en su estado de reposo o de movimiento rectilíneo uniforme a menos que otros cuerpos actúen sobre él. Explica que para modificar el estado de movimiento de un cuerpo es necesario actuar sobre él. Segunda ley o Principio Fundamental de la Dinámica : Esta ley dice que la fuerza que actúa sobre un cuerpo es directamente proporcional a su aceleración. Es decir, si sobre un cuerpo actúa una fuerza, dicho cuerpo modificará su velocidad, es decir, adquirirá una aceleración. Dicha fuerza y su aceleración generada son proporcionales y están relacionadas mediante: F=m*a donde F es la fuerza aplicada, m es la masa del cuerpo sobre el que se aplica la fuerza y a es la aceleración adquirida por dicho cuerpo.Tercera ley o Principio de acción-reacción : Esta ley expresa que cuando un cuerpo ejerce una fuerza sobre otro, éste ejerce sobre el primero una fuerza igual y de sentido opuesto.Entonces, la Ley de atracción no pertenece a los tres principios de Newton.

Two balls have the same mass. One ball moving along the positive x–axis and the other ball moving along the positive y–axis undergo perfectly inelastic collision. What can you say about the motion of the balls after the collision?
A.
The balls stick and move together.
B.
The balls separate immediately.
C.
The first ball stops while the other ball starts moving.
D.
The two balls travel off in opposite directions, 180° apart.
Answer:
A. The balls stick and move together.
Explanation:
When a bodies undergo perfectly inelastic collision, the two bodies stick together after the collision and begins to move.
In this collision, kinetic energy is not conserved. For perfectly elastic collision, the two bodies conserve kinetic energy and begin to move apart.
Kinetic energy is not conserved because some of the energy gets converted into other forms of energy.

20. Show that an acceleration of 0.67 m/s/s is the result if a force of 1000N is exerted on a 1500 kg
car.
Explanation:
Given parameters:
Mass of the car = 1500kg
Force applied = 1000N
Acceleration = 0.67m/s²
Unknown:
Proof that the acceleration will result from the applied force on the car
Solution:
According to newton's second law of motion,
Force = mass x acceleration
So;
Acceleration = [tex]\frac{Force }{mass}[/tex]
Now insert the parameters and solve;
Acceleration = [tex]\frac{1000}{1500}[/tex] = 0.67m/s²
We have shown that the acceleration is 0.67m/s²
A net force of 10.N accelerates an object at 5.0 m/s^2. What net force would be required to accelerate the same object at 1.0 m/s^2?
A.) 1.0 N
B.) 5.0 N
C.) 50. N
D.) 2.0 N
Answer:
I believe the answer is 2.0
Explanation:
The net force that would be required is 2 N
From the question,
We have that
A net force of 10 N accelerates an object at 5.0 m/s².
To determine the net force that would be required to accelerate the same object at 1.0 m/s²,
First, we will determine the mass of the object
From the Newton's second law of motion, we have that
F = ma
Where F is the force
m is mass
and a is acceleration
From the given information
F = 10N
a = 5.0 m/s²
Putting the above parameters into the formula, we get'
10 = m × 5.0
∴ m = 10 ÷ 5.0
m = 2 kg
∴ The mass of the object is 2kg
Now,
For the net force that would be required to accelerate the same object at 1.0 m/s²,
Using the same formula
F= ma
Here,
a = 1.0 m/s²
and m = 2 kg
∴ F = 2 × 1
F = 2 N
Hence, the net force that would be required is 2 N

A rock falls off a cliff that is 82 m high. How fast is the rock moving when it hits the ground?
Answer:
40.1m/s
Explanation:
This is a kinematics problem
x = 82m
a = -9.8m/s^2
v(initial) = 0
Find: v(final)
Using kinematics equation:
vf^2 = vi^2 + 2a(delta)x
vf^2 = 0 + 2*(-9.8)*(82)
vf = sqrt(1607.2) = 40.09m/s
The is traveling with a velocity of 40.1m/s when it hits the ground.
Write one example situation of Newton's Third Law involving mass that are the same.
Answer:
Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.
